Items to Check Before the Test Run
1. Turn the remote power switch on at

least 5 hours before the test, in order
to energize the crankcase heater.

2. Turn the outdoor service valves (2

locations) to the full-open positions.

Use caution when making the

settings. If there are duplicated
system addresses, or if the settings
for the number of the indoor units are
not consistent, an alarm will occur
and the system will not start.

These settings are not made on the

indoor unit PCB.
