INSTALLATION REQUIREMENTS
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 horizontal position without modification.
The horizontal left and downflow positions require product modification.
This product is designed for zero inch (0") clearance; however, adequate access for service or
replacement must be considered without removing permanent structure. This unit can be installed
on a platform when deemed necessary.
In an attic installation a secondary drain pan must be provided 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 unconditioned spaces
where sweating may occur.
Appliances installed in garages, ware houses or other areas where they may be subjected to
mechanical damage must be suitably guarded against such damage by installing behind 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 flammable vapors, must be installed with the ignition source at least 18"
above the floor level.
When more than one appliance is installed in a building, permanently identify the unit as to
the area or space serviced by that applice.

The condensate drain line must be at least 3/4 NPT, for each unit. Precautions must be
used not to over tighten the adapter at the drain pan connection, this precaution will
prevent damage to the plastic drain pan. A joint compound should be used to prevent
leakage and act as a lubricant.
When using copper tubing as a condensate line adequate caution muat be taken to prevent
damage to the plastic drain pan during the soldering process. All condensate drain lines
and drain traps should be adequately insulated.
The unit and the auxiliary drain pan must be adequately elevated to insure proper drainage.
Use of a condensate removal pump is permitted when necessary.This condensate pump
should have provisions for shutting off the control voltage should a blocked drain occur. A
trap must be installed between the unit and the condensate pump. Important: The evaporator
coil is coated with oils that will dissolve Styrofoam and certain types of plastics. Therefore
a removal pump or float switch must not contain any of these materials.

encountered in installations.
The CFM can be checked by the following method;
(The optional Heat Kit must be installed to continue with this procedure.)
1) All access panels must be in place.
2) Start the unit in the heat mode.
3) Measure the return air temperature.
4) Measure the supply temperature. This measurement should be done in various locations
to obtain an average.
5) Subtract the return temperature from the supply temperature. This is referred to as the
temperature rise.
6) Measure the actual supply voltage and actual amperage at the terminal block/circuit
breaker.
7) The BTUH output = (Voltage x Amps x 3.41)
output (BTUH)
CFM =
1.08 X temperature rise
