5 Pre-Installation Considerations
5.1 Preparation
Keep this document with the unit. Carefully read all
instructions for the installation prior to installing product.
Make sure each step or procedure is understood and
any special considerations are taken into account before
starting installation. Assemble all tools, hardware and
supplies needed to complete the installation. Some items
may need to be purchased locally. Make sure everything
needed to install the product is on hand before starting.
5.2 System Matches
The entire system (combination of indoor and outdoor
sections) must be manufacturer approved and Air-
Conditioning, Heating, and Refrigeration Institute (AHRI)
listed. NOTE: Installation of unmatched systems is not
permitted.
5.3 Interconnecting Tubing
Give special consideration to minimize the length of
refrigerant tubing when installing air handlers. Refer to
Remote Cooling / Heat Pump Service Manual RS6200006,
and TP-107 Long Line Set Application R-410A for tubing
guidelines. If possible, allow adequate length of tubing such
that the coil may be removed (for inspection or cleaning
services) from the cabinet without disconnecting the tubing.
5.4 Clearances
The unit clearance from a combustible surface may be
0”. However, service clearance must take precedence. A
minimum of 24” in front of the unit for service clearance
is required. Additional clearance on one side or top will
be required for electrical wiring connections. Consult all
appropriate regulatory codes prior to determining final
clearances. When installing this unit in an area that may
become wet (such as crawl spaces), elevate the unit with a
sturdy, non-porous material. In installations that may lead
to physical damage (i.e. a garage) it is advised to install a
protective barrier to prevent such damage. Always install
units such that a positive slope in condensate line (1/4” per
foot) is allowed.
5.5 Horizontal Applications
If installed above a finished living space, a secondary
drain pan (as required by many building codes), must be
installed under the entire unit and its condensate drain line
must be routed to a location such that the user will see the
condensate discharge.
5.6 Access
This unit should be installed in a manner so that it is not
accessible to the public.
6 Installation Location
NOTE: These air handlers are designed for indoor
installation only at a max altitude of 10,500 feet above
sea level or a min altitude of -184 feet below sea level.
If the unit is located in an unconditioned area with high
ambient temperature and/or high humidity, the air handler
may be subject to nuisance sweating of the casing. On
these installations, a wrap of 2” fiberglass insulation
with a vapor barrier is recommended. A secondary drain
pan below the unit is also recommended to protect the
installation site.
This product line may be installed in one of the upflow,
downflow, horizontal left or horizontal right orientations as
shown in Figures 3, 4, 5 and 6. The unit may be installed
in horizontal left orientation as shipped (refer to specific
sections for more information).
6.1 Upflow and Downflow Installation (Figure 3 & 4)
1. Remove blower access panel and coil access panel.
The coil access panel and tubing panel may remain
screwed together during this procedure. Remove and
retain the seven (7) screws securing the coil access
panel to the cabinet and the six (6) screws securing
the blower access panel to the cabinet.
2. Slide the coil assembly out from the cabinet. Use the
drain pan to pull the assembly from the cabinet.
IMPORTANT: Do not use manifolds, copper lines,
or the flowrator to pull the coil assembly out.
Failure to do so may result in braze joint damage
and leaks.
3. Removal of the center support is required on units
with 21” wide cabinet. Remove and retain the two (2)
screws that secure the center support to the cabinet.
Remove the center support.
4. The horizontal drip shield, side drain pan, and
drain pan extension must be removed. Follow
the “Side Drain Pan and Extension Removal
Instructions”.
5. For Upflow Installation:
a. Using the drain pan to hold the coil assembly,
slide the coil assembly back into the cabinet.
b. Reinstall the center support (if removed) using the
two (2) screws removed in Step 3.
c. Reinstall the coil access panels and reinstall
blower access panel removed in Step 1 as shown
in Figure 9.
