REPLACEMENT PARTS SOURCE
Replacement parts are available through local distributors.When ordering replacement parts, give the COMPLETE model and serial numbers shown on the rating plate.
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, warehouses 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 generat 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.
