(1) All loose matter is removed from the cabinet especially 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
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 test run.
Explain the contents of the Installation Instructions, and then have the customer actually operate the system.
