2. SAFE INSTALLATION REQUIREMENTS Installation and servicing of air-conditioning equipment can be hazardous due to system pressure and electrical components. Only trained and qualified personnel should install, repair, or service air-conditioning equipment. Untrained personnel can perform basic maintenance functions of cleaning coils and filters. All other operations should be performed by trained service personnel.

Do NOT install the unit in a location that will permit discharged air from the condenser to recirculate to the condenser inlet. - Platform must be high enough to allow for proper condensate trap installation and drainage. See Figure 2 and associated text for more information about condensate drainage. Rooftop UNIT DAMAGE HAZARD Installation Rooftop platform requirements: Failure to follow this caution may result in shorten life of unit components.

supplied condensate trap that will allow a standing column of water of at least 2" (50.8mm) MUST be installed. Top of outlet from trap MUST be at least 1" (25.4mm) below top of outlet from unit. Install the trap as near to the unit as possible for proper drainage, A 3/4" (19.1 mm) drain line MUST be installed if required by local codes or if location of unit requires it.

"W/W1 ", "Y1", "Y2", and "G'. Some electronic thermostats use low voltage from the unit for power for temperature display and programming. These electronic thermostats will have a "C" terminal. The outdoor unit has color-coded wires for easy connection. Using wire nuts, follow FIGURE 4 for proper connections: FIGURE 3 Thermostat Connections Ductwork sizing affects the discharge temperature, airflow velocity, and efficiency of the system.
