1. Preparing for Test Run

zBefore attempting to start the air conditioner, check the fol- lowing.

(1)All loose matter is removed from the cabinet, especially steel fi lings, bits of wire, and clips.

(2)The control wiring is correctly connected and all electrical connections are tight.

(3)The protective spacers for the compressor used for trans- portation have been removed. If not, remove them now.

(4)The transportation pads for the indoor fan have been removed. If not, remove them now.

(5)The power has been connected to the unit for at least 5 hours before starting the compressor. The bottom of the compressor should be warm to the touch and the crank- case heater around the feet of the compressor should be hot to the touch.

(6)Both the gas and liquid tube service valves are open. If not, open them now.

(7)Request that the customer be present for the trial run. Explain the contents of the instruction manual, then have the customer actually operate the system.

(8)Be sure to give the instruction manual and warranty cer- tifi cate to the customer.

(9)When replacing the control PCB, be sure to make all the same settings on the new PCB as were in use before replacement.

The existing EEP ROM is not changed, and is connected to the new control PCB.
