10-19. Items to Check Before the Test Run
(1) Turn the remote power switch ON at least 12 hours in
advance in order to energize the crank case heater.
(2) Fully open the closed valves on the liquid-tube and gas-
tube sides.
10-20. Test Run Using the Remote Controller
(1) Press and hold the remote controller
button for 4
seconds or longer. Then press the
button.
●
“TEST” appears in the LCD display during the test run.
●
Temperature control is not possible when test run mode
is engaged.
(This mode places a large load on the devices. Use it
only when performing the test run.)
(2) Use either Heating or Cooling mode to perform the test
run.
Note: The outdoor unit will not operate for approximately 3
minutes after the power is turned ON or after it stops
operating.
(3) If normal operation is not possible, a code appears on the
remote controller LCD display.
Refer to “10-21. Table of Self-Diagnostic Functions and
Corrections” and correct the problem.
(4) After the test run is completed, press the
button again.
Check that “TEST” disappears from the LCD
display. (This remote controller includes a function that
cancels test run mode after a 60-minute timer has elapsed,
in order to prevent continuous test run operation.)
(5) For the test run of an inverter outdoor unit, operate the
compressors for a minimum of 10 minutes (in order to
check for open phase).
* When performing a test run using a wired remote
controller, operation is possible without attaching the
cassette-type ceiling panel.
(“P09” will not be displayed.)
