5 PRE-INSTALLATION INSTRUCTIONS
5.1 Preparation
Keep this document with the unit. Carefully read all instruc-
tions 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 instal-
lation. 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 sec-
tions) must be manufacture approved and Air-conditioning,
Heating, and Refrigeration Institute (AHRI) listed.
NOTE: Installation of unmatched systems is not per-
mitted. Damage or repairs due to installation of un-
matched systems is not covered under the warranty.
5.3 Interconnecting Tubing
Give special consideration to minimize the length of refrig-
erant 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.
Note:
These air handlers are designed for indoor installa-
tion 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.
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.
6 APPLICATION INFORMATION
The unit is designed to be installed in conditioned space,
either recessed into a wall or hanging in a vertical
“upflow” position. If units are recessed in a wall, use
the holes along the inside of the front flange to attach
units to the framing studs. The vertical air handler comes
equipped with an offset hanging bracket attached to the
rear of the cabinet for hanging applications.
IMPORTANT: Unit must be installed level or slightly
tilted back to ensure proper drainage of condensate.
The air handler also has a bottom and front return.
Large
chassis installations should be installed as front return
only
. If the small chassis air handler is to be installed in
a bottom return application, discard the drain access
panel in the bottom of the unit. If the air handler is to be
installed in a front return application, remove and discard
the front access panel with insulation. The unit is shipped
with a filter rack and filter. Remember to inspect, clean
and/or replace the filter monthly.
