9-10. 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.

9-11. Preparation for Test Run

9-11-1. Switching the temperature sensor

●

Temperature sensors are contained in the indoor unit

and wireless remote controller. One or the other of the
temperature sensors is used for operation.

●

(body sensor) appears on the LCD display of the

wireless remote controller, then the indoor unit body sensor
is used for operation.

To switch to the remote controller sensor, open the remote
controller cover and press the SENSOR button once. The

(body sensor) display disappears and the remote control

sensor is used for operation.

N OT E

●

Even if the remote controller sensor is selected, the sensor

will be automatically switched to the indoor unit body sensor
if no temperature signal has been received from the remote
controller for 10 minutes. Install the remote controller in a
position where the signal can be reliably received by the unit.

●

When group control is engaged, be sure to use the body

sensor.

9-11-2. Using the remote controller

●

Face the remote controller toward the receiver (on the main

unit). (Fig. 9-8)

●

The signal can be received up to a distance of approximately

8 m.
Use this distance as a guide. This distance may vary
somewhat depending on the battery capacity and other
factors.

●

Be sure that there are no objects between the remote

controller and the receiver which may block the signal.

●

The unit beeps when a signal is received correctly.

(For operation start only, the unit beeps twice.)

●

Do not drop, throw, or wash the remote controller.

●

Do not place the remote controller in locations exposed to

direct sunlight or nearby a stove.

9-12. Test Run

Using the control unit

(1) Change the indoor control unit switch from “ON”

→

“TEST”.

(The outdoor unit will not operate for 3 minutes after the
power is turned ON and after operation is stopped.)

(2) All the indicator lamps blink while the test run is in

progress.

(3) Temperature control is not possible during the test run.

(4) If correct operation is not possible, the trouble will be

indicated by the indicator lamps. Refer to “Table of Self
Diagnostic Functions and Corrections” and correct the
problem.

(5) After the test is completed, change the control unit switch

from “TEST”

→

“ON”. Confirm that the indicator lamps

have stopped blinking. (A function is included which
cancels the test run after a 60-minute timer has elapsed, in
order to prevent continuous test run operation.)

N OT E

●

This mode places a large load on the devices. Use it only for

performing test runs.

●

A test run is not possible if the power is turned ON with the

switch in the TEST position.
After the power has been turned ON, change the switch
once to ON or OFF, then switch it back to the TEST position.

9-13. 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 wiring 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 (0.5 A for both indoor and
outdoor units) will blow in order to protect the PCB. Correct
the wiring connections, then disconnect the 2P connectors
(indoor: blue) (outdoor: blue, serial 1) that are connected
to the PCB, and replace them with 2P connectors (indoor:
brown) (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.) (Fig. 9-9)
