WARNING
When installing or servicing this equipment, safety
clothing, including hand and eye protection, is
strongly advised. If installing this equipment in an
area that has special safety requirements (hard hats
etc.), observe these requirements. To protect the
unit when brazing close to the painted surfaces,
the use of a quenching cloth is strongly advised to
prevent scorching or marring of the equipment fin-
ish.
WARNING
If this appliance is installed in an enclosed area
such as a garage or utility room with any carbon
monoxide (CO) producing appliance (i.e. automo-
bile, furnace, water-heaters, etc.), ensure the area
is properly ventilated.
WARNING
The unit MUST have an uninterrupted, unbroken
electrical ground to minimize the possibility of per-
sonal injury if an electrical fault should occur. The
electrical ground circuit may consist of an appro-
priately sized electrical wire connecting the
ground lug in the unit control box to the building
electrical service panel. Other methods of ground-
ing are permitted if performed in accordance with
the “National Electric Code” (NEC)/“American Na-
tional Standards Institute” (ANSI)/“National Fire
Protection Association” (NFPA) 70 and local/state
codes. In Canada, electrical grounding is to be in
accordance with the Canadian Electric Code CSA
C22.1. Failure to observe this warning can result
in electrical shock that can cause personal injury
or death.

Installation
Before installing this appliance insure that it is properly sized
and adequate power is available.
This appliance can be installed in the vertical or right horizon-
tal position without modification. The horizontal left and
downflow positions require product modification.
This product is designed for zero inches (0 inches) clear-
ance; however, adequate access for service or replacement
must be considered without removing permanent structure.
This unit can be installed on a platform when deemed neces-
sary.
In an attic installation a secondary drain pan must be pro-
vided by the installer and placed under the entire unit with a
separate drain line properly sloped and terminated in an area
visible to the owner. This secondary drain pan is required in
the event that there is a leak or main drain blockage. Closed
cell insulation should be applied to the drain lines in uncondi-
tioned spaces where sweating may occur.
Appliances installed in garages, warehouses or other areas
where they may be subjected to mechanical damage must
be suitably guarded against such damage by installing be-
hind protective barriers, being elevated or located out of the
normal path of vehicles. When installed on a base, the base
must also be protected by similar means.
Heating and cooling equipment located in garages, which
may generate a glow, spark or flame capable of igniting flam-
mable vapors, must be installed with the ignition source at
least 18"[46cm] above the floor level.
When more than one appliance is installed in a building it
shall be permanently identified as to the area or space ser-
viced by the equipment.
When this product is installed in the downflow installation in
an unconditioned space, remove the horizontal drain pan and
install the following insulation kit
