Before attempting to start the air conditioner,
check the following:
(1) All loose matter is removed from the cabinet espe-
cially steel filings, 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
transportation 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 supplied 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 crankcase heater around the feet of the com-
pressor should be hot to the touch. (Fig. 6-1)
(6) Both the gas and liquid tube service valves are open.
If not, open them now. (Fig. 6-2)
(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
certificate 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 EEPROM is not changed, and is
connected to the new control PCB.
