LOCATION
Location is usually predetermined. Check with owner's or
dealer's installation plans. If location has not been decided,
consider the following in choosing a suitable location:
1. Select a location with adequate structural support, space
for service access, clearance for air return and supply
duct connections.
2. Use hanging brackets to wall mount unit as shown
below.
3. Normal operating sound levels may be objection able if
the air handler is placed directly over some rooms such
as bedrooms, study, etc.
4. Precautions should be taken to locate the unit and ductwork so that supply air does not short circuit to the return
air.
5. Select a location that will permit installation of a trapped
condensate line to an open drain.
6. When an evaporator 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.
The coil is provided with a secondary drain. It 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.
7. Proper electrical supply must be available.
8. Clearances must also be taken into consideration, and
provided for as follows:
a. Refrigerant piping and connections are located in
the front.
b. Maintenance and servicing through the front or
access side of unit with both sides and rear of unit
having zero inch clearance.
c. Condensate drain lines are connected in the front
(clear of filter).
d. Filter removal.
e. When no electric heat is used, the unit as well as all
duct work and plenum are designed for zero clear-
ance to combustible materials.
If Electric Heat is used, a minimum clearance of one
inch must be maintained on all sides of the supply
air duct and/or plenum continuously for up to 3 feet.

HORIZONTAL DRAIN PAN INST ALLATION /
CONVERSION
These air handler units are supplied ready to be installed in a
right hand horizontal position when a horizontal pan is factory
installed. If unit requires field installation of a horizontal pan or
requires left hand positioning, the unit must have the pan
installed in the correct position.
NOTE: Models bearing a “H” indicates the unit has horizontal
drain pan factory installed in position “A”. (See Figure 4).
1. Remove blower access, coil access, and center access
panels.
NOTE: Conversion must be made before brazing the refrigerant connections to the coil.
2. See Figure 4, remove two screws from horizontal drain
pan, to remove pan from position “A” if factory installed.
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 supplied with the unit. Ensure that the drain pan is
lying flat against the insulati on of th e ca binet.
7. Horizontal drain cutout in the center access panel should
be removed by using a utility knife (if not previously cut
out).
DO NOT TRY TO KNOCK OUT.
8. Re-position and replace access panels.
Models F(2,3)FP045,048,060 have a coil baffle and
support bracket factory installed for right hand horizontal application (refer to Figure 4C). 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.
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.

FIGURE 5 : Dimensions & Duct Sizes
DUCT CONNECTORS
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.
NOTE: The electric heat accessory should be installed before
the supply 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 5 for dimensions for
duct inlet and outlet connections.
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 installation that the duct system be properly designed and installed.
C
E
18-3/8
BOTTOM VIEW
Use flexible duct collars to minimize the transmission of vibration/noise into the conditioned space. If electric heat is used,
non-flammable material must be used.
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 throug h an
uncooled space during the cooling season. The use of a
vapor barrier is recommended to prevent absorption 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 hangers 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 5.
Duct work should be fabricated and installed in accordance
with local and/or national codes. This includes the standards
of the National Fire Protection Association for Installation of
Air-Conditioning and Ventilating Systems, NFPA No. 90B.

AIR FILTERS
Air filters must be field supplied. A 1" filter access rack has
been built into the unit. See Figure 4. Remove filter access
cover shown. Install proper size filter. Standard 1" size permanent or throw away filter may be used, or, permanent
washable filters are available using model numbers:
1PF0601, 602, 603BK. See Table 2 for filter size.
Equipment should never be operated without filters.
SUSPENSION KITS
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.
For suspension of these units in horizontal applications, it is
recommended to use angle steel support brackets with
threaded rods, supporting the units from the bottom, at the
locations shown in Figure 6.
