10-4. 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-

(1) Press and hold the remote controller
seconds or longer. Then press the
●
"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 "10-7. Table of Self-Diagnostic Functions and
Corrections" and correct the problem.
(4) After the test run is completed, press the
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.)
10-6. Precautions
● Request that the customer be present when the test run is
performed. At this time, explain the operation manual and
have the customer perform the actual steps.
● Be sure to pass the manuals and warranty certificate to the
customer.
● Check that the 220 – 240 V AC power is not connected to
the inter-unit control wiring connector terminal.
* If 220 – 240 V AC is accidentally applied, the indoor or
outdoor unit control PCB fuse will blow in order to protect
the PCB. Correct the wiring connections, then disconnect
the 2P connectors (indoor: blue, OC) (outdoor: blue, serial
1) that are connected to the PCB, and replace them with
2P connectors (indoor: brown, EMG) (outdoor: brown,
serial 2). If operation is still not possible after changing
the brown connectors, try cutting the varistor (black) (both
indoor and outdoor).
(Be sure to turn the power OFF before performing this
work.)
