INTRODUCTION
Customer Service
Thank you for purchasing a WhisperKOOL split system. We strive to provide the highest quality products
and the best possible customer service. If you have any questions about your WhisperKOOL unit, please call
Using this Manual
This Owner’s Manual is intended to be a general WhisperKOOL split system installation and maintenance
guide. Please use the supplied unit specific installation guide in conjunction with this manual. In order to
ensure the longevity of your cooling system, the equipment should be installed properly and have a proper
care and maintenance schedule. Please read and review this manual carefully and keep it for future refer-
ence.
What is a WhisperKOOL Split System?
Specialized refrigeration systems designed for one purpose only: to maintain the optimal temperature and
humidity levels conducive to the proper storage and aging of fine wines. Split systems produce minimal
in-cellar noise and have the most lenient exhaust requirements. An exterior housing is required for outdoor
condensing unit installations.
How Does a WhisperKOOL Split System Work?
Similar to the air conditioning systems used for homes, the evaporator and condensing units are installed
in separate locations and are connected by a line set. The evaporator portion is commonly installed in the
wine cellar, with the condensing unit located either outside or in a remote indoor location.

PREPARING THE WINE CELLAR
The performance and life of your WhisperKOOL system are contingent upon the steps you take in preparing
the wine cellar.
Note: Improperly preparing your enclosure or incorrectly installing your WhisperKOOL system may cause
unit failure, leaking of condensation, and other negative side effects.
IT IS HIGHLY RECOMMENDED THAT YOU OBTAIN THE ASSISTANCE OF A
WINE STORAGE PROFESSIONAL.
Wine storage professionals work with licensed contractors, refrigeration technicians, and racking companies
to build well-insulated, beautiful, and protective wine cellars. WhisperKOOL has put together some useful
tips to assist in the installation process. Our recommendations are meant to act as a guide in the process of
building a proper enclosure. Your intended location may have specific needs that we do not address.
Wall & Ceiling Framing
Build wine cellar walls using standard 2x4 or 2x6 construction methods and ceiling joists following the
guidelines of local and state codes in your area. As a general rule, the thicker the walls and the higher the
insulation factor in your cellar, the better it will be at maintaining a consistent temperature.
Insulation
Insulation is REQUIRED with the use of the WhisperKOOL product. Standard fiberglass or rigid foam insula-
tion is normally used in cellar construction or, in some cases, “blown-in”insulation is used. It is very impor-
tant that all walls and ceilings are insulated to keep the cellar temperature as consistent as possible during
the summer and winter months. The R-factor, or quality of insulation, is determined by the rate at which
heat passes through the insulation. The higher the R-factor, the more resistant the insulation is to conduct-
ing heat. Using higher R-values in insulation will lower your operating costs and unit run time.
Vapor Barrier
Vapor barrier is REQUIRED to prevent the intrusion of water vapor so that the cellar can be kept at the cor-
rect temperature and humidity. 6 mm plastic sheeting (recommended) should be applied to the warm side
of the cellar walls. The vapor barrier must also be applied to the outside walls and ceiling. If it is impossible
to reach the outside, then the plastic must be applied from within the cellar. The most common method is
to wrap the entire interior, leaving the plastic loose in the stud cavity so the insulation can be placed be-
tween each stud. All of the walls and ceiling must be wrapped in plastic for a complete vapor barrier.
In areas of high humidity, such as Southern and Gulf States, the vapor barrier will prevent infiltration of
warm moist air. The moist air can cause mold to form, and standing water in drain pans promote microbial
and fungal growth that cause unpleasant odors and indoor air quality problems. If mold is found, remove it
immediately and sanitize that portion of the system.
Door and Door Seal
An exterior grade (1 3/4”) door must be installed as a cellar door. It is very important that weather stripping
is attached to all 4 sides of the doorjamb. A bottom “sweep”or threshold is also required. The door must have
a very good seal to keep the cool cellar air from escaping out of the cellar. One of the most common prob-
lems with cooling units running continually is the door not sealing properly. In cases where glass doors are
used and the room size is close to the recommended unit size, the next larger size WhisperKOOL should be
used. This will compensate for the insulation loss due to the inefficient door.

Unobstructed Airflow
Unobstructed airflow to and from both the evaporator and condenser is a critical factor in the system’s over-
all performance. Make sure there is a 3 ft. horizontal clearance in the front of both units. This will assure that
the air can circulate in an efficient manner. Avoid any attempt to camouflage the evaporator by installing
racking in front of the unit. This will restrict the airflow and reduce system performance.
In-Cellar Mounting
If you are mounting your evaporator in the cellar, it should be mounted within 18“ of the top of the room in
order to achieve sufficient cooling. As the room cools down, the warm air will rise to the ceiling. Mounting
the evaporator high in the room will create a consistently cool environment by capturing the warm air and
replacing it with cool air. Mounting the evaporator low in the room will result in a temperature variation in
the room due to the unit’s inability to draw warm air from the ceiling of the cellar to the unit itself.
Ducting
Some systems are designed to have the air exchange happen out of the cellar using duct work. This allows
the evaporator unit to placed in a variety of positions around the cellar and in some models up to 25 duct
feet away. The return air (from cellar to unit) needs to be located low in the cellar with the supply air (from
unit to cellar) should be located high in the cellar. This greatly increases the efficiency of the cooling system
by allowing the cold air travel throughout the entire cellar space and absorb as much heat as possible.

SPLIT SYSTEM INSTALLATION
General Installation Guidelines and Instructions
WhisperKOOL requires that a certified HVAC technician install and charge all split systems. Please take a
moment to review state and city building codes to ensure the safe and proper installation of the system.
Electrical Needs
WhisperKOOL split systems requires a dedicated 110-volt 20-amp circuit. The system draws a large amount
of amps at initial start up. By designating a dedicated circuit breaker, you will guarantee that the system has
enough power to run effectively. Contact an electrician for assistance with the installation of this dedicated
electrical circuit:
1. Match the electrical outlet to the plug provided on the WhisperKOOL unit.
2. Provide a dedicated circuit and wiring for the unit.
3. Provide a weatherproof plug for units mounted outside.
WE RECOMMEND THAT YOU DO NOT USE A GROUND FAULT INTERRUPTER (GFI) WITH THIS PRODUCT.
In case the system should lose power, press the reset button and attempt to turn the unit back on. Check
the home/main circuit breaker. If the unit does not respond properly, refer to the Troubleshooting section
on page 17.
Condensing Unit Preparation
Note: The condensing unit is shipped with a protective foam pad/ block to prevent damaging tubing
against the condenser coil fins. Please ensure that this pad is removed prior to operation.
*A Low Ambient Control is used on most models,
a Fan Cycling Switch is used otherwise.

Installing the Condensing Unit
The condensing unit can be mounted inside a utility area of the home or outside utilizing the required
outdoor condensing unit housing. The condenser requires a dedicated 20 amp circuit, non-GFI. Make sure
there is a minimum three-foot horizontal clearance in front and rear of the unit. The unit may either be hard
wired or plug-in depending on local electrical codes.
Inside Condensing Unit Installations: Inside installations require special consideration, as there
must be adequate ventilation to dissipate the heat created during normal operations. An exhaust
port with fan may need to be installed to ensure that heat is effectively removed from the utility
room. A return grille or provision for 500 - 600 cfm of cool air to enter the room to replace the ex-
hausted air will accomplish this. Unobstructed airflow to and from the unit is a critical factor in the
unit’s overall performance. Make sure there is a minimum three-foot horizontal clearance in front
and rear of the unit. This will assure that the unit can move the air around the room in an efficient
manner.
Outdoor Condensing Unit Installations. You must utilize the exterior condensing unit housing for
outdoor installations. Place the condensing unit on a solid foundation in a location with adequate
ventilation. There should be three feet of clearance in the front and rear of the unit and one foot on
each side. The unit should be elevated 18 inches in order to avoid any possible flooding or damage
by animals, and should be clear of leaves, dirt, and other debris.

SPLIT SYSTEM INSTALLATION (cont’d)
Installing the Evaporator Unit
Please refer to the supplied Unit Specific Installation Guide
for detailed evaporator installation guidelines.
Head Pressure Control, Low Ambient Control Switch, Fan Cycling Switch:
These switches are used to cycle the condenser fan at low ambient temperature conditions. If your unit is
equipped with a Low Ambient Control, set the switch to 170 psig for cut-in and 70 psig for the differential.
Further adjustment may be needed. Verify the settings via refrigeration manifold gauge and perform the
final adjustments to the readings on the gauge manifold. If your condensing unit is not equipped with a Low
Ambient Control, it features a pre-set Fan Cycling Switch.
Refrigeration Lines
A 1/4 inch O/D copper “liquid line”and a 3/8 or 1/2 inch O/D copper “suction line”connect the two units.
The refrigerant drier and the sight glass shall be installed (in that order) in the direction of the refrigerant
flow in the liquid line between the condensing unit and evaporator. Enclose the suction line in a cellular
insulation ½”wall thickness Armaflex (brand name) or equal to reduce heat transfer.
Wiring System
The compressor is controlled by a “pump down cycle,”therefore, no wiring between the condensing unit
and evaporator unit is necessary. Wire the system in accordance with local codes and the enclosed wiring
diagrams (pg 22). The evaporator unit requires a standard 20 amp circuit, non-GFI. A dedicated circuit is not
mandatory, but recommended.
Charging the System (by Certified HVAC technician)
After all the piping is complete:
Open both of the service valves on the condensing unit (the unit is pressurized with nitrogen, and there
should be an audible sound of gas escaping through the service ports).
With electrical power connected to the evaporator unit, energize the solenoid valve (pressurize with dry
nitrogen) to 200psi. Leak test all fittings. The system must hold 200psi for 30 minutes.
If no leaks are found, leave the solenoid valve energized and evacuate the system through both the liquid
and suction service ports. Using a high vacuum pump, evacuate to 200 microns, measuring the vacuum
with a digital micron gauge. When evacuation is complete, break vacuum and pressurize with liquid R-134A
refrigerant.
With the electrical power turned on to the condensing unit, and the evaporator unit running, slowly feed
liquid refrigerant (R134A) into the suction service port. As the suction pressure rises to 15 PSIG, the condens-
ing unit will start. Slowly feed refrigerant while maintaining a pressure above 10 PSIG to prevent the com-
pressor from short cycling. Slowly feed refrigerant with the compressor running until the sight glass is clear
of all bubbles. Do not exceed 3.5 lbs of refrigerant. Check superheat at the evaporator outlet. Superheat
should be at 10°-12°. Check the compressor crankcase temperature after 30 minute run time – it should be
hot (115°to 140°). If it is cooler, superheat is too low. Adjust TXV to recommended superheat.
Allow the system to operate for one hour and then check the refrigerant level in the sight glass again. Ad-
ditional refrigerant may be required as the temperature of the enclosure is lowered to approximately 55°F or
the ambient temperature at the condensing unit rises above the temperature at which the unit was initially
charged. Depending on temperature, the “high side”should be approximately 175 lbs, and the ”low side”28
lbs or more to keep the evaporator from icing. It is recommended while charging to use a digital refrigerant
scale for better accuracy in measuring the amount of charge.

DUCTED INSTALLATION
Ducting the supply and return air to the cellar creates a virtually silent cellar space and also maximizes cellar
capacity. It is absolutely crucial to only use insulated duct work as it minimizes cooling loss, prevents sweat-
ing, and reduces noise. Failure to use insulated ducting will cause the unit to run excessively and greatly
shorten its lifespan.
Note: Do not exceed a total of 25 duct feet between the evaporator and cellar vent, this means a total of 50’
combined for both the supply and return lengths.
Avoid crimping the flexible ducts. This chokes down the inside area and reduces the airflow causing the unit
to lose efficiency. Be sure all ducts and surfaces in contact with the airflow are insulated and have a vapor
barrier on the outside.
Un-insulated ducts and surfaces cause bare, exposed metal surfaces to sweat, further degrading the
insulation and equipment cooling capacity.
General Duct Recommendations:
•
•
•
•
•
•
•
•
•
Provide support for the flexible duct to prevent sags and bends
Stretch out the duct to make a smoother interior, which reduces air resistance
For 90° bends, use a 90° adjustable elbow (Ell)
Do not squeeze or reduce the inside diameter of the ducts, which reduces airflow
Use short and straight duct work where possible
Remove the grilles and panels from the openings to connect the duct work
Check that all fan blades move freely
Keep air paths free of loose foreign objects and debris
Connect the round flexible ducts to the WhisperKOOL system using the duct collars provided with
the duct accessory kit
•
Pull the outer plastic wrapping and insulation away from the end of the duct to expose the reinforced
inside duct liner
•
•
Fasten the duct collar using tie straps or clamps around the inside liner
Secure the duct collar to the unit using the screws provided. Take care to not damage or bend the
gasket
•
Use approved duct tape to seal all joints
Do not clamp around the outside insulation,
as it will compress and loosen over time.
Note: When performing a ducted installation, it is crucial
to not forget about routing the bottle probe into the cellar.
The system must have the sensing bottle in the cellar to
maintain the cellar environment.

LIQUID MEASURING THERMOMETER
Most WhisperKOOL systems come equipped with a liquid temperature measuring thermometer probe . This
self calibrating probe contains a sensor chip, which actually communicates back and forth to the thermostat.
This results in a consistent liquid temperature as air temperature fluctuates
Measuring liquid temperature has a couple unique advantages:
1. The temperature of the wine can be more precisely controlled, ensuring a more consistent overall
temperature.
2. The system will switch on/off less often, extending cooling system life.
To use the thermostat:
1. Fill an empty wine bottle 3/4 full with room temperature tap
water
2. Press bottle probe securely into bottle
3. Place the bottle with probe into a level rack space. Avoid pull-
ing too much on the probe cord, it may become disconnected
resulting in non-operation of the unit.
Remember: The WhisperKOOL System maintains cellar environ-
ment based on the liquid temperature. It is ideal to place the
probed bottle lower in the racking so that it is not near cold supply
air.
Note: When performing a ducted or remote installation, it is cru-
cial to not forget about routing the bottle probe into the cellar. The
system must have the sensing bottle in the cellar to maintain the
cellar environment.

When power is applied to the unit, the control will
briefly display all symbols, and the Snow Flake
symbol will be displayed (if unit is calling for cool-
If the condensing unit is installed outside (which will
allow the condenser to be exposed to low ambient
temperatures), the condenser fan may cycle on and
ing). There may be a brief delay prior to the evapora- off. The purpose of the fan cycling is to maintain
tor fan turning on, as the fan will not turn on until
the evaporator probe temperature drops to the
perspective start temperature (below 70°F). When
the evaporator fan is activated the Fan symbol will
be displayed. The temperature control feature for
the evaporator fan is a feature applicable to Whis-
perKOOL. This is the Advance Product Safety Tech-
nology (APST), which ensures that in the possible
event of a cooling deficiency, the heat from the
the system high side pressure, which will ensure
an adequate refrigeration process. The fan cycling
process is accomplished by way of a Johnson Control
attached to the condensing unit.
Bottle Probe Failure Protection
In the event that a bottle probe should fail, the APST
(Advance Product Safety Technology) will automati-
cally transition the Refrigeration Compressor cycles

the evaporating unit is placed in a remote location
outside of the cellar.
Anti Short Cycle
The Anti Short Cycle ensures that the unit will re-
main off for a period of 5 minutes after the unit has
reached the set point to allow the pressure in the
refrigeration system to equalize prior to starting the
compressor.
Anti Frost Cycle
The Anti Frost Cycle is a precautionary measure, as
icing or frosting of the coil does not occur during
normal operation. The system will go through a
defrost cycle every 4 hours. During the defrost cycle,
the indoor fan will provide air flow across the indoor
coil, which will evaporate any frost accumulation.

Tune”the Control Operating System to their applicable choice.
The following CPSM options are available for adjustment:
Fon – Humidity Management Enhancement: This parameter is normally set at 5, which should
provide adequate relative humidity for the cellar.
•
An increase in this parameter will increase the Humidity Enhancement (%RH), and a decrease
in the parameter will decrease Humidity Enhancement (%RH).
•
•
Adjustments should be made in increments of 5, with a maximum of 15, and a minimum of 0.
After any adjustment to Humidity Enhancement, you should wait a minimum of three days
before making any additional adjustments. This will allow the cellar sufficient time to accli-
mate to the new setting.
Fof - Humidity Management Enhancement: This parameter is normally set at 1. This parameter
should not be adjusted, as it simply provides an OFF cycle time for the fan, during the compres-
sor OFF cycle. However, the parameter is located within the CPSM as a convenience to the cus-
tomer, should it need to be adjusted.

1. Condensate drain
clogged
Clear out drain
2. Evaporator coil
frozen
Clean the coil and / or fan wheel
Call a CERTIFIED HVAC service technician.
3. Drain line improperly
installed
Wine cellar temperature above thermostat set point
1. Large quantity of warm
wine placed in cellar
Allow time for wine to cool
2. Wine Cellar Door left
open for long period.
Close Door. Allow time for wine to cool.
3. No power to either
evaporator or condensing
unit
Is the thermostat display illuminated?
If not, check power supply switch, if equipped. Ensure it is in the
ON position.
If on, check to see in the breaker is tripped.
If tripped, reset and check display.
Check breaker to condensing unit. If tripped, check to see if com-
pressor is hot – too hot to touch. If so, allow to cool for one (1)
hour before resetting breaker.
After cooling, reset breaker and note whether it remains set or
trips off. If it trips, call a CERTIFIED HVAC service technician for
repair.

If the breaker remains set, check to see if compressor is
running and condenser fan turns on.
After compressor runs a few minutes, check the refrigerant
“sight glass”in the ¼”copper tubing. Look for bubbles.
If no bubbles are present and compressor is running,
refrigerant system is running OK.
If bubbles are present, system is low on refrigerant.
A CERTIFIED HVAC service technician will have to locate and
repair any refrigerant leaks, then add refrigerant.
Condenser fan should come on either immediately on
compressor start or after sight glass gets warm.
If not, compressor will trip off on high pressure safety
control, reducing capacity and possibly tripping the
breaker.
In this event, CERTIFIED HVAC service technician will have
to check for the problem.
