9. TEST RUN

9-1. Preparing for Test Run

● Before attempting to start the air conditioner, check the
following:
(1) All loose matter is removed from the cabinet especially
steel filings, bits of wire, and clips.
(2) The control wiring is correctly connected and all electrical
connections are tight.
(3) The protective spacers for the compressor used for
transportation have been removed. If not, remove them
now.
(4) The transportation pads for the indoor fan have been
removed. If not, remove them now.
(5) The power has been supplied to the unit for at least 5
hours before starting the compressor. The bottom of
the compressor should be warm to the touch and the
crankcase heater around the feet of the compressor should
be hot to the touch. (Fig. 9-1)

(Power must be turned ON at least
5 hours before attempting test run)

(6) Both the gas and liquid tube service valves are open. If
not, open them now. (Fig. 9-2)
Liquid tube
(7) Request that the customer be present for the test run.
Explain the contents of the instruction manual, and then
have the customer actually operate the system.
(8) Be sure to give the instruction manual and warranty
certificate to the customer.
(9) When replacing the control PCB, be sure to make all the
same settings on the new PCB as were in use before
replacement.
The existing EEPROM is not changed, and is connected to
the new control PCB.

9-2. Caution

●
This unit may be used in a single-type refrigerant
system where 1 outdoor unit is connected to 1 indoor
unit.
●
The indoor and outdoor unit control PCB utilizes
a semiconductor memory element (EEPROM). The
settings required for operation were made at the time of
shipment.
Only the correct combinations of indoor and outdoor
units can be used.
●
This test run section describes primarily the procedure
when using the wired remote controller.

9-4. 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.

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 "9-7. 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

9-6. 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.

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 con-
nectors, try cutting the varistor.
(Be sure to turn the power OFF before performing this work.)
