8-2. Test Run Procedure

Items to Check Before the Test Run

<Outdoor unit control PCB> Unit No. setting switch (S004)

Recheck the items to check before the test run.

Set the No. of indoor units.

1.Turn the remote power switch on at least 5 hours before the test, in order to energize the crank case heater.

2.Turn the outdoor service valves (2 locations) to the full-open positions.
