2-4. 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-tube sides.

2-5. Test Run Using the Remote Controller

(1) Press and hold the remote controller
4 seconds or longer. Then press
"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 "2-7. 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.)
2-6. 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.
If operation is still not possible after changing the
brown connectors, try cutting the varistor.
(Be sure to turn the power OFF before
performing this work.)
