7-2. Test Run Procedure
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 Nos. 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.
