These air handler units are supplied ready to be installed in a right hand
horizontal position. If unit requires left hand positioning, the unit must
have the pan installed in the correct position.
DO NOT TRY TO KNOCK OUT PANEL OPENING FOR SECOND-
ARY DRAIN PAN. SEE ITEM 7.
1. Remove blower access, coil access, and center access panels.
NOTE: Conversion must be made before brazing the refrigerant con-
nections to the coil.
2. See Figure 3, remove two screws from horizontal drain pan, to
remove pan from position “3A” if factory installed.
Models F*FP045,048,060 have a coil baffle and support bracket
factory installed for right hand horizontal application (refer to Figure
3C). For left hand applications the coil support bracket must be
moved to the right side of the coil, and the coil baffle must be
rotated to avoid water blow-off.
To rotate baffle, remove the coil assembly from the unit (remove
front two screws holding the coil support bracket and the two
screws holding the drain pan). Remove four screws in coil baffle
and remove the coil baffle and rotate ends.
3. Position horizontal pan, as required in either “A” or “B” position,
locking it into the vertical drain pan as shown.
4. Horizontal drain pans have 4 plugged drains. Remove plugs from
connections being used.
NOTE: If this step is overlooked, it can lead to a water problem later.
5. Use removed plug to plug primary of upflow drain pan.
6. Attach horizontal pan with 2 screws removed in step no. 2 or sup-
plied with the unit. Ensure that the drain pan is lying flat against the
insulation of the cabinet.
Resecure the baffle and reinstall the coil assembly ensuring that
the rear of the drain pan is secured under the back flange of the
unit. Reinstall the coil support bracket on the right side of the coil.

A suspension kit is available. Models 1BH0601 (unit sizes 018-060) is
designed specifically for the units contained in this instruction (upflow
application only). For installation of these accessory kits, see the
instructions packed with the kit.
DUCT CONNECTIONS
For suspension of these units in horizontal applications, it is recom-
mended to use angle steel support brackets with threaded rods, sup-
porting the units from the bottom, at the locations shown in Figure 5.
Use 1/2" screws to connect ductwork to bottom of unit. Longer
screws will pierce the drain pan and cause leakage. If pilot holes
are drilled, drill only though field duct and unit bottom flange.
COIL METERING DEVICES
The coil in this Air Handler unit will have a TXV metering device
installed at the factory.
NOTE: The electric heat accessory should be installed before the sup-
ply air duct is attached to the supply air openings. Refer to the electric
heater kit instructions for proper installation.
Air supply and return may be handled in one of several ways best
suited to the installation. See Figure 4 for dimensions for duct inlet and
outlet connections.
The model number will have the following format:
F*FPxxxH06T2y - The coil will have a Thermal Expansion Valve (TXV)
installed. The y character specifies which TXV is installed at the factory.
Please refer to the TXV Metering Device section for installation notes.
The vast majority of problems encountered with combination heating
and cooling systems can be linked to improperly designed or installed
duct systems. It is therefore highly important to the success of an instal-
lation that the duct system be properly designed and installed.

Where return air duct is short, or where sound may be a problem,
sound absorbing glass fiber should be used inside the duct. Insulation
of duct work is a must where it runs through an unheated space during
the heating season or through an uncooled space during the cooling
season. The use of a vapor barrier is recommended to prevent absorp-
tion of moisture from the surrounding air into the insulation.

The supply air duct should be properly sized by use of a transition to
match unit opening. All ducts should be suspended using flexible hang-
ers and never fastened directly to the structure. This unit is not
designed for non-ducted (freeblow) applications. Size outlet plenum or
transition to discharge opening sizes shown in Figure 4.

Relieve pressure by removing plug from piping connection. Coil will
have factory installed TXV. See outdoor unit documentation for cor-
rect TXV to be used. Refer to unit nameplate for TXV identification
for this unit.
FIGURE 8: Control Board
Mark the unit nameplate with the appropriate heater selection on the
space provided or NONE to indicate cooling only. To operate these units
with electric heat, it is necessary to field install an electric heater kit
(2HK). See Electric Heater Kit Accessory Installation instructions for
proper installation procedure. Prior to installing electric heat, it is neces-
sary to perform the following procedure:
NOTE: The coil should be open to the air for no more than 2 minutes to
keep moisture and contaminates from entering the system. If the coil
cannot be brazed into the refrigeration system in that time, the ends
should be temporarily closed or plugged. For a short term delay, use
masking tape over the ends of the copper tubing to close the tube to the
air. For a longer term delay, use plugs or caps. There is no need to
purge the coil if this procedure is followed.
1. Remove the 4-pin power plug from the control board (See Figure
8).
NOTE: This pin must not be used when electric heaters are installed.
2. Remove the four (4) screws from the duct cover and remove the
duct cover from the air handler.
REFRIGERANT LINE CONNECTION
See the outdoor unit installation instructions for the procedure to install
field supplied tubing for systems with sweat fittings.
Right-hand Airflow Application Only - Models with Circuit
Breakers - See Figure 9
Stub adapters are available to adapt sweat connections to quick con-
nections.
If unit is to be installed for right hand air flow, the circuit breakers in the
heat kit will need to be removed and rotated 180°, so the OFF position
will be down when the cabinet is positioned on the right side. This is an
NEC requirement. Do One Breaker At A Time - to make sure wires
are reconnected properly. Loosen terminal screws on the wires and
gently pull the wires back from the breaker. Remove screws securing
the breaker plate and rotate 180°, then secure the breaker plate and
reconnect the wires to the breaker. Proper torque for terminal screws is
35 in/lbs.
Connect lines as follows:
NOTE: Route the refrigerant lines to the coil in a manner that will not
obstruct service access to the coil, air handling system or filter.
1. Suction line connections are made outside the center access
panel. Center access panel is recessed to assure sufficient room
for brazing or it can be removed and slid over the suction line dur-
ing brazing.
2. Plan for TXV bulb placement.

NOTE: It is possible to vary the amount of electric heat turned on during
the defrost cycle of a heat pump. Standard wiring will only bring on 5
KW of electric heat during defrost see Table 6 and Figures 12 and 13 for
alternate staging.
LOW VOLTAGE CONTROL CONNECTION
The 24 volt power supply is provided by an internally wired low voltage
transformer which is standard on all models. However, if the unit is con-
nected to a 208 volt power supply the low voltage transformer must be
rewired to the 208 volt tap. See the unit wiring label.
LINE POWER CONNECTIONS
Field supplied low voltage wiring can exit the unit on the top right hand
corner or the right hand side panel (see Fig. 5, item K).
Power may be brought into the unit through the supply air end of the
unit (top when unit is vertical) or the left side panel. Use the hole appro-
priate to the unit's orientation in each installation to bring conduit from
the disconnect. The power lead conduit should be terminated at the
electrical control box. Refer to Tables 4, 8 & 10 for wire requirements.
Also see Figure 10.
Install a 7/8" plastic bushing in the selected hole and keep low voltage
wiring as short as possible inside the control box.
The field wiring is to be connected at the screw terminals of the control
board. Refer to Figure’s 12 and 13.
NOTE: All wiring must comply with local and national electrical code
requirements. Read and heed all unit caution labels.

possible provided the CFM does not exceed limitations and the sound
level is not objectionable.
BLOWER SPEED CONNECTIONS
Except for F4FP045, which has a 4-speed motor, and F5FP* which has
a 5-speed high efficiency X-13 motor, all air handlers contain three
speed blower motors which are pre-wired to the control board.
Connect motor wires to motor speed tap receptacle for speed desired.
See wiring label for motor wiring details. See Figure 11.
Adjust blower motor speed to provide airflow within the minimum and
maximum limits approved for evaporator coil, electric heat and outdoor
unit. Speed tap adjustments are made at the motor terminal block, See
Figure 11. Airflow data is shown in Tables 6 and 11.
The unit control is designed for the addition of a two speed fan kit. See
accessory kit for details.

The drain pan connections are designed to ASTM Standard D 2466
Schedule 40. 3/4" PVC is preferred. Since the drains are not subject to
any pressure it is not necessary to use Schedule 40 pipe for drain lines.
DRAIN CONNECTIONS
All drain lines should be trapped a minimum of three inches, should be
pitched away from unit drain pan and should be no smaller than the coil
drain connection.
It is recommended that all drain connections be sealed with teflon tape
or equivalent.
MAINTENANCE
Filters must be cleaned or replaced when they become dirty. Inspect at
least once per month. The frequency of cleaning depends upon the
hours of operation and the local atmospheric conditions. Clean filters
keep unit efficiency high.
Threaded drain connection should be hand-tightened, plus no
more than one turn.
COIL CLEANING
If the coil needs to be cleaned or replaced, it should be washed with
Calgon CalClean (mix one part CalClean to ten parts water). Allow solu-
tion to remain on coil for 30 minutes before rinsing with clean water.
Solution should not be permitted to come in contact with painted sur-
faces.
Horizontal drain cutout in the center access panel should be
removed by using a utility knife. DO NOT TRY TO KNOCK OUT.
Route the drain line so that it does not interfere with accessibility to the
coil, air handling system or filter and will not be exposed to freezing
temperatures. See Figures 2, 3 and 4.
LUBRICATION
The bearings of the blower motor are permanently lubricated.
NOTE: When the coil is installed in an attic or above a finished ceiling,
an auxiliary drain pan should be provided under the coil as is specified
by most local building codes.
CONDENSATE DRAINS
Coils should be installed level or pitched slightly toward the drain end.
Suggested pitch should not exceed 1/4 inch per foot of coil.
During the cooling season check the condensate drain lines to be sure
that condensate is flowing from the primary drain but not from the sec-
ondary drain. If condensate ever flows from the secondary drain the unit
should be promptly shut off and the condensate pan and drains cleaned
to insure a free flowing primary drain.
The coil is provided with a secondary drain that should be trapped and
piped to a location that will give the occupant a visual warning that the
primary drain is clogged. If the secondary drain is not used it must be
capped.
TROUBLESHOOTING GUIDE
PROBLEM
POSSIBLE CAUSE
1. No heat units do not have 6-pin connector installed.
2. Limit open or not connected.
Blower Runs all of the time
3. Variable speed break-out tab broken out.
4. Blower OFF delay (approx. 1 min).
5. Thermostat fan switch in “ON” position.
Blown Fuse
No 24V
1. Low voltage short to C or ground from R, Y, G, W, or O.
1. 4-pin connector loose.
2. Loose wire from control to transformer (24V and 230V).
3. Blown fuse on control board.
1. Check 6-pin connector and connections to panel mount relays.
2. Verify that both W1 & W2 are connected at the terminal strip.
No 2nd stage heat
1. Check filter.
2. Closed registers.
No Heat or Limited Heating
3. Restricted airflow (supply registers or return registers)
4. Check blower motor operation.
5. If the safety limit opens 4 times, the control will not permit the heating element to operate for 1 hour.
