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 crankcase heater.
(2) Fully open the closed valves on the liquid-tube and gastube sides.
Test Run Using the Remote Controller
(1) Press and hold the remote controller
"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.
The outdoor unit will not operate for approximately 3 minutes after the power is turned ON or after
N OTE
it stops operating.
(3) If normal operation is not possible, a code appears on the remote controller LCD display.
Refer to the section "Table of Self-Diagnostic Functions and Corrections" and correct the problem.
(4) After the test run is completed, press the
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.)
Precautions
Request that the customer be present when the test run is performed.
At this time, explain the Operating Instructions 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 that are connected to the PCB, and
replace them with 2P connectors.
If operation is still not possible after changing the brown connectors, cut off the jumper (outdoor unit : JP007)
or the varistor (indoor unit) on the PCB. (Be sure to turn the power OFF before performing this work.)
