General Information
Inspection
When the equipment is received, all items should be carefully checked against the bill of lading to make sure all crates
and cartons have been received. All units should be carefully inspected for hidden damage when received. If any dam-
age is found, it should be reported to the carrier immediately and a claim should be filed. The unit nameplate should be
checked to make sure that the voltage agrees with the power supply available.
Installation
NOTE: Installation and maintenance are
to be performed only by qualified
CAUTION: Sharp edges and coil surfaces are
a potential injury hazard. Avoid
personnel who are familiar with
local codes and regulations, and
contact with them.
experienced with this type of
equipment.
Installation and service of this equipment should be performed only by qualified and experienced commercial refrigeration
mechanics. Correct application and installation of this equipment is necessary to obtain optimum performance and
customer satisfaction. Install all equipment, piping and electrical in accordance with local and national codes and in
conformance with good practice required for proper operation. Work safely! Prevent accidents!
The final step in any installation is to instruct the customer or user in the operation of the equipment. The customer
should be shown how the equipment can be made to operate properly and efficiently. Maintenance requirements
should be explained.
Expansion Valve
Install expansion valve and feeler bulb inside cabinet of the unit. Recommended valve sizes are given for each
product family.
Drain Line
After installing the fan panel assembly, connect the drain line to the fitting provided on the unit. A plastic hose or
metal drain line can be used.
The drain line should be pitched sharply and exit the cabinet as quickly as possible. Traps in the drain line should
be located in a warm ambient to prevent freeze-up.
If only a small portion of the drain line is located in the refrigerated area, a drain line heater will not be required.
If a drain line heater is required, use approximately 15 watts per foot of pipe. Connect the heater wire to the
terminals of the heater circuit (N and 3) at the terminal block in the junction box. The heater will then operate
during the defrost cycle.
All condensate water must be disposed of properly and should not be allowed to accumulate or cause a safety
hazard.
Motors
Motors are lifetime lubricated and thermally protected. Check an inoperative motor by disconnecting and applying
correct voltage across leads. If test fails, replace the motor.
Wiring
The nameplate on the unit is marked with the electrical characteristics to be used for wiring the unit. The unit must
be grounded. All wiring should be done in accordance with applicable national and local codes.
Maintenance
Periodically inspect unit for grease and soil accumulation. Clean with warm water and soap. Do not use cleaners containing
ammonia. Inspect the drain pan/fan panel occasionally for proper condensate drainage. Keep the drain opening clean.
WARNING: All power must be disconnected before cleaning drain pan/fan panel. It serves as a cover
of hazardous moving parts. Operation of unit without pan in place constitutes a hazard.
WARNING: Refrigerant can be harmful if it is inhaled. Refrigerant must be used and recovered
responsibly. Failure to follow this warning may result in personal injury or death.

ELECTRIC DEFROST TROUBLESHOOTING
The electric defrost units are relatively simple and trouble-free in operation:
Timer
If the system does not go through its proper sequence , check timer operation through a defrost cycle. Check for loose
wires or terminals. Before replacing timer, check other components.
Operation of Paragon Timer
To set time of day grasp knob which is in the center of the inner (fail-safe) dial and rotate it in a counter-clockwise direction.
This will cause the outer (24 hour) dial to revolve. Line up the correct time of day on the outer dial with the time pointer.
Do not try to set the time control by grasping the other (24 hour) dial. Place pins in the outer dial at the time of day that
defrost is required.
Operation of Grasslin Timer
To set the time, turn the minute hand clockwise until the time of day (and AM or PM) on the outer dial is aligned with the
triangle marker on the inner dial. Do not rotate minute hand counter-clockwise. Move the white tab (tripper) on the
outer dial outward at each desired initiation time. Each white tab (tripper) is a 15 minute interval and provides 15 minutes
of defrost. For longer defrost duration, move additional tabs (following in time) from the initiation tab. For example, if a
45 minute defrost is to start at 7:00 AM, move the tabs outward that lie between 7:00 - 7:15, 7:15 - 7:30 and 7:30 - 7:45
on the AM side of the dial. The defrost will initiate at 7:00 AM and time terminate at 7:45 AM (if temperature termination
does not occur first).
Fan Motor
If the motor does not operate or it cycles on thermal overload, remove motor leads from terminal block and apply correct
voltage across the leads. If motor still does not operate satisfactorily, it must be replaced. Before starting the unit, rotate
fan blades to make sure they turn freely and have sufficient clearance.
Fan Delay & Defrost Termination Control
This control is a single pole double throw switch. The red lead wire is wired to common. The black wire is wired in series
with the fan motors. The brown wire is wired in series with the defrost termination solenoid in the timer. The brown and
red contacts close and the black and red contacts open when the temperature is above 55ºF. The black and red contacts
close and the brown and red contacts open when the temperature is below 35ºF.
On initial “pull down” of a warm box the fan will not start until the coil temperature reaches approximately 35ºF. If the box
is still comparatively warm (60ºF) when the fan starts, then blowing this warm air over the coil may cause it to warm up
to 55ºF and thus stop the fan. Therefore, the fan may recycle on initial “pull down.” This control cannot be adjusted.
If the fan motor fails to start when the control is below 35ºF, disconnect the fan motor leads and check the motor as
described for fan motors. Also check whether current is being supplied at “N” and “4” from the timer. The fan delay
control must be below 35ºF when checking for a closed circuit.
Defrost Heater
If unit shows very little or no defrosting and does not heat, disconnect heater and check to find if it is burned out. To test,
apply correct voltage across heater or use continuity flashlight battery tester.
Drain Pan
If drain pan has an ice build-up, drain line may be frozen. The drain line should be pitched sharply and exit cabinet
as quickly as possible. Sometimes location and ambient at the drain outside of cabinet may cause freeze-up. A drain
line heater may be required to correct the freeze-up. Any traps in the drain line must be located in a warm ambient.
NOTE: After correcting faulty condition it is
essential that the coil and unit be free of
ice before placing unit back on automatic
operation.

Sequence of Operation
2. The compressor now starts.
Step “A” - Normal Refrigeration Cycle
3. Then fan motors remain off because the fan delay thermostat
is open. This prevents warm air from being blown into the
refrigerated space.
4. The evaporator coil cools down approaching operating
temperature. Superheated gas only passes to the compressor.
1. Power is supplied to N and 4 terminals by the timer.
2. The fan delay and defrost termination thermostat is closed in
the fan delay position and open in the defrost termination position.
3. The defrost heater is off.
4. The compressor operates in accordance with the demands of
the refrigeration system temperature and/or pressure controls.
5. The unit cooler fan operates continually.
Step “D” - Return to Normal
Refrigeration Operation
6. Frost builds up slowly on the evaporator.
1. When the coil temperature reaches 35ºF, the fan control switch
closes. This allows current to flow to the fan motor and the unit is
now back in operation as in Step “A.”
Step “B” - Defrost Cycle
1. Defrosting of the evaporator is started automatically by the
timer at predetermined times - typical settings of the timer would
be 1 to 3 defrost periods per 24 hours.
IMPORTANT
1. On initial “pull down” of a warm box, the fan will not start
until coil temperature reaches approximately 35ºF. If box is still
comparatively warm (60ºF) when the fan starts, then blowing this
warm air over the coil may cause it to warm up to 55ºF and thus
stop the fan. Therefore, fan may recycle several times on initial
“pull down.”
2. The timer has an adjustable fail-safe feature which will return
the system to the refrigeration cycle at the end of a predetermined
time (factory set at 24 minutes) if automatic control devices fail.
3. Frequent defrost periods are not necessary! The determining
factor for number of defrosts per day is the frost load. When frost
“build-up” results in a loss of refrigeration capacity, then a defrost
is required. One to three defrosts per day are recommended.
4. A low temperature thermostatic expansion valve with pressure
limiting feature is desirable for use with these units. Such a valve
prevents feeding of refrigerant to the coil during the defrost cycle.
2. The timer mechanically opens switch “A” which breaks the
circuit to the compressor and evaporator fan motors, thereby
shutting them off, and closes switch “B,” thereby permitting current
to flow to the heater.
3. The heater recessed in slots, gives up heat directly to the fins
of the evaporator. This heat raises coil and refrigerant temperature
to 32ºF causing the frost to melt.
4. Frost on the evaporator is melted and defrost water drips into
the heated drain pan and flows down the drain.
5. When frost has completely melted from the coil, the coil starts
to warm up beyond 32ºF.
Step “C” - Coil Re-Cooling Cycle
1. When the coil warms up to 55ºF, the defrost termination
thermostat closes which allows the current to flow to the solenoid
in the timer, which then energizes and trips the timer switch back
to its normal position (switch “A” closed, switch “B” open). The fan
delay portion of this thermostat is now open.

Mounting
The standard flow mullion unit draws air in at the top and
discharges out the bottom. The reverse flow mullion draws
air in at the bottom and discharges out the top. The unit may
be mounted in a mullion or against a back or side wall.
A top barrier is supplied and must be used if combustible
material is above the unit. On reverse flow models the
barrier may be used to direct the air straight out or up at a
45° angle. Holes and slots are provided to adjust the barrier.
If noncombustible material is used above the unit, the barrier
may be discarded if desired.
When mounting to the mullion of under counter refrigerators,
mounting holes are located on both ends of the unit for
attaching to “customer furnished” mounting brackets.
Knockouts are provided for bringing the refrigerant piping
through either end of the cabinet. An electrical knockout is
provided into an internal junction box.
Whenwallmounted,four“L”typebracketsandeightstainless
steel sheet metal screws are provided to attach the brackets
to side panels.

Mounting
The Wall Mount Back Bar Unit Cooler is a low height unit designed for undercounter applications. Air is drawn in at the
bottom of the unit and discharged out the front. Two mounting angles are included with the unit and should be installed
to space the unit 3/4” off the wall. Air deflector(s) are included and can be mounted over the top half of the fan guard
to direct the air up. The deflector may be left off if total horizontal air movement is desired. If used, the deflector can be
field formed to direct the air where needed. Locating holes and screws are provided.
