Test run
Before test run
• Before turning on the power supply, carry out the
following procedure.
1) By using 500 V-megger, check that resistance
of 1 M
Ω
or more exists between the terminal
block L to N and the ground.
If resistance of less than 1 M
Ω
is detected, do
not run the unit.
2) Check the valve of the outdoor unit being
opened fully.
• To protect the compressor at activation time, leave
power-ON for 12 hours or more before operating.
• Do not press the electromagnetic contactor to
forcibly perform a test run. (This is very dangerous in
case the protective device does not work.)
• Before starting a test run, set addresses by following
the Installation Manual supplied with the outdoor
unit.
Execute a test run
• When a fan operation is to be performed for an
individual indoor unit, turn off the power, short CN72
on the circuit board, and then turn the power back
on. (First set the operating mode to “fan,” and then
operate.) When the test run has been performed
using this method, do NOT forget to release the
shorting of CN72 after the test run is completed.
Operate the unit with the wired remote control as usual.
For the procedure of the operation, refer to the
attached to the outdoor unit Owner’s Manual.
A forced test run can be executed in the following
procedure even if the operation stops by turning the
thermostat - OFF.
In order to prevent a serial operation, the forced test
run is released after 60 minutes have passed and
returns to the usual operation.
CAUTION
Do not use the forced test run for cases other than the
test run because it applies an excessive load to the
devices.
