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 crank
case heater.
2. After performing the leak inspection, applying
vacuum, and performing refrigerant charge for
the tubing which is connected on-site, fully open
the outdoor unit service valve. However if only
one outdoor unit is installed, a balance tube is
not used. Therefore, leave the valve fully closed.
3. When replacing the control PCB, be sure that
the settings on the new PCB match those on the
old PCB.
4. 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.
5. These settings are not made on the indoor unit
PCB.
