-11. Auto address setting from the outdoor unit

●

  If the power can be turned ON separately for the indoor and outdoor units in each system:

The indoor unit addresses can be set without running the compressor.

●

  Be sure to use a jig for short-circuiting.

(1)  Turn on the indoor and outdoor unit power for refrigerant system 1. 

 

Short-circuit the A.ADD pin.

 

 

↓

 

Communication for auto address setting begins.

 

 

↓

 

LED 1 and 2 on the outdoor unit control PCB blink alternately, and turn OFF when address setting is completed.

 

 

↓

 

<Approximately 4 – 5 minutes are required.>

(2)  Next, turn ON the power only at the indoor and outdoor units in a different system. Short-circuit the A.ADD pin.

 

 

↓

 

LED 1 and 2 on the outdoor unit control PCB blink alternately, and turn OFF when address setting is completed.

 

 

↓

 

Repeat the same procedure for each system and complete auto address setting.

2-12. Test run using the indicator of the indoor unit (Type K2)

(1)  Press and hold [Emergency Operation]   button of the indoor unit for four 

seconds or more.

(2)  Then the lamps on the display will blink one after another.

(3)  Release the button and again press and hold [Emergency Operation]   button 

for four seconds or more.

(4)  All indicator lamps on the display blink while test run is in progress.

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

(6)  If normal operation is not possible, the lamps on the display will indicate the problem. 

See the section 2-10.

(7)  After the test run is completed, press [Emergency Operation]   button and confirm that

the indicator lamps stop blinking.(A 60-minute automatic OFF timer function is included 
in order to prevent continuous test run.)

. Caution for Pump Down

Pump down means refrigerant gas in the system is returned to the outdoor unit. Pump down is used when the unit is to be moved, or 
before servicing the refrigerant circuit.

CAUTION

●

  This outdoor unit cannot collect more than the rated refrigerant amount as shown by the nameplate on the back.

●

  If the amount of refrigerant is more than that recommended, do not conduct a pump down. In this case use another 

refrigerant collecting system.

●

  Pay a special attention to the rotating of the fan while operating.

How to perform Pump-Down (Refrigerant recovery) properly

(1)  Stop operation of the unit (cooling, heating etc.).
(2)  Connect the pressure gauge to the service port of the gas tubing valve.
(3)  Short-circuit the “PUMPDOWN” pin on an outdoor unit control PCB (CR) for 

 

more than 1 second to release.

 

• Pump-Down begins and the unit starts operating.

 

•  During Pump-Down, LED1 blinks and LED2 is lit on an outdoor unit control 

 

PCB (CR).

 

• “CHK” blinks on the remote controller.

(4)  Fully close the liquid tubing valve 2-3 minutes later.

 

The Pump-Down will begin.

(5)  When the pressure gauge drops to 0.1-0.2MPa, close the gas tubing valve 

 

tightly and short-circuit the “PUMPDOWN” pin for more than 1 second to release. 

 

That is the end of Pump-Down.

 

•  When running for more than 10 minutes, it stops even if the Pump-Down is not completed.

 

Check the blocked state of the liquid side valve.

 

•  It also stops when the “PUMPDOWN” pin is short-circuited during the operation.

*  For compressor protection, do not operate to the point where the unit tubing side reaches negative pressure.

HOW TO INSTALL WIRELESS REMOTE  CONTROLLER

N OT E

See section “8. HOW TO INSTALL THE WIRELESS REMOTE CONTROLLER RECEIVER”.

 SERVICING

CAUTION

●

  Any qualified person who is involved with working on or breaking into a refrigerant circuit should hold a current valid certificate 

from an industry-accredited assessment authority, which authorizes their competence to handle refrigerants safely in 
accordance with an industry recognised assessment specification.

●

  Servicing shall only be performed as recommended by the equipment manufacturer. Maintenance and repair requiring the 

assistance of other skilled personnel shall be carried out under the supervision of the person competent in the use of flammable 
refrigerants.

●

  Servicing shall be performed only as recommended by the manufacturer.

●

  Prior to beginning work on systems containing flammable refrigerants, safety checks are necessary to ensure that the risk of 

ignition is minimised. For repair to the refrigerating system, (2) to (6) shall be completed prior to conducting work on the system.

(1) 

Work shall be undertaken under a controlled procedure so as to minimise the risk of a flammable gas or vapour being present 
while the work is being performed.

(2) 

All maintenance staff and others working in the local area shall be instructed on the nature of work being carried out. Work in 
confined spaces shall be avoided. The area around the workspace shall be sectioned off. Ensure that the conditions within the 
area have been made safe by control of flammable material.

(3)  The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure the technician is aware 

of potentially toxic or flammable atmospheres. Ensure that the leak detection equipment being used is suitable for use with all 
applicable refrigerants, i.e. non-sparking, adequately sealed or intrinsically safe.

(4) 

If any hot work is to be conducted on the refrigeration equipment or any associated parts, appropriate fire extinguishing 
equipment shall be available to hand. Have a dry powder or CO

2

 fire extinguisher adjacent to the charging area.

(

5)  No person carrying out work in relation to a refrigeration system which involves exposing any pipe work shall use any sources 

of ignition in such a manner that it may lead to the risk of fire or explosion. All possible ignition sources, including cigarette 
smoking, should be kept sufficiently far away from the site of installation, repairing, removing and disposal, during which 
refrigerant can possibly be released to the surrounding space. Prior to work taking place, the area around the equipment is to 
be surveyed to make sure that there are no flammable hazards or ignition risks. “No Smoking” signs shall be displayed.

Pay a special attention to the rotating 

of the fan while operating.
