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.

Installation
Before installing this appliance insure that it is properly sized and adequate power is available.
This appliance can be installed in the vertical position with- out modification.
The horizontal left and downflow positions require product modification and instructions for these field conversions can be found in the AVPTC installation instruction manual.
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.
