SAFETY CONSIDERATIONS Installing, starting up, and servicing air−conditioning equipment can be hazardous due to system pressures, electrical components, and equipment location (roofs, elevated structures, etc.). Only trained, qualified installers and service mechanics should install, start−up, and service this equipment. Untrained personnel can perform basic maintenance functions such as cleaning coils. All other operations should be performed by trained service personnel.

WIRING All wires must be sized per NEC (National Electrical Code) or CEC (Canadian Electrical Code) and local codes. Use Electrical Data table MCA (minimum circuit amps) and MOCP (maximum over current protection) to correctly size the wires and the disconnect fuse or breakers respectively. Per the caution note, only stranded copper conductors with a 600 volt rating and double insulated copper wire must be used. The use of BX cable is not recommended.

1. Carefully remove the mounting plate, which is attached to the back of the indoor unit. 2. The mounting plate should be located horizontally and level on the wall. All minimum spacings shown in Fig. 3 and 5 through 8 should be maintained. 3. If the wall is block, brick, concrete or similar material, drill .2” (5 mm) diameter holes and insert anchors for the appropriate mounting screws. 4. Attach the mounting plate to the wall.

Triple Evacuation Method The triple evacuation method should only be used when the vacuum pump is only capable of pumping down to 28 in. of mercury vacuum and the system does not contain any liquid water. Refer to Fig. 22 and proceed as follows: 1. Pump the system down to 28 in. of mercury and allow the pump to continue operating for an additional 15 minutes. 2. Close the service valves and shut off the vacuum pump. 3.

TROUBLESHOOTING For ease of service, the systems are equipped with diagnostic code display LEDs on both the indoor and outdoor units. The outdoor diagnostic display is two LEDs (Red and Green) on the outdoor unit board and is limited to very few errors. The indoor diagnostic display is a combination of flashing LEDs on the display panel or the front of the unit. If possible, always check the diagnostic codes displayed on the indoor unit first.
