The owner should be made familiar with the location of the over-current protection, the proper size for this application and the proper procedure for disconnecting power service to the unit.

The condensing unit control wiring requires a 24 Volt minimum, 25 VA service from the indoor transformer as shown on the wiring diagram.

7.SYSTEM STARTUP

1.Turn thermostat to "OFF", turn on power supply at disconnect switch. 2.Turn temperature setting as high as it will go.

3.Turn fan switch to "ON". Indoor blower should run. Be sure it is running in the right direction. 4.Turn fan switch to "AUTO". Turn system switch to "COOL" and turn temperature setting below room temperature. Unit should run in cooling mode.

5.Check to see if compressor and outdoor fan are running correctly?

6.Check the refrigerant charge (see Instructions under "Charging the System").

7.Replace service port caps. Service port cores are for system access only and will leak if not tightly capped.

8.Check unit for tubing and sheet metal rattles. 9.Instruct the owner on operation and maintenance.
