CHARGELESS SYSTEM
PRE-CHARGED REFRIGERANT IS SUPPLIED FOR MAXIMUM PIPING LENGTH AT SHIPMENT.
The unique refrigerant circuit and a large accumulator always control the optimal refrigerant level regardless of the length
(30m max. and 5m min.) of piping. The additional refrigerant charging work during installation often causes problems.
Heretofore it is completely eliminated. This unique system improves the quality and reliability of the work done. It also helps
to speed up the installation time.

8-4. OUTDOOR UNIT SERVICE FUNCTIONS (OUTDOOR CONTROLLER BOARD)
(1) Compulsory defrosting
1When all of the following conditions are satisfied, pressing SW2 starts the compulsory defrosting.
● During HEAT mode
● The compressor is ON.
● The outdoor coil temperature is being displayed by LED. (Outdoor controller board dip switch SW3-1 : OFF, SW3-2 :
ON)
● The outdoor coil thermistor reads 8°C or below.
2The operation state and the termination conditions of the compulsory defrosting are the same as those of the normal
defrosting. As an exception, the defrost interval after the defrosting completion is 50 minutes.
(2) Fixed fan-output
While the compressor is operating (except during defrosting) and the fan output step is indicated by LED, pressing SW2
fixes the fan output. The fixed fan-output can be released when any of the following conditions are satisfied.
1SW2 is pressed again.
2SW3 setting is changed.
3The compressor stops.
4Defrosting operation starts.
(3) Function of switches on the outdoor controller board
SW1: Clears the check code memory (push-button switch)
SW2: Switches the output state indication and the check code display (push-button switch)
SW3-1,2: Switches the output state indication items (dip switch)
(4) 100% fan output
Fan output is fixed to 100% by shorting the connector CN22. However, the fan stops during compressor OFF or defrosting.
Open-circuit of CN22 restarts the normal fan control.
(5) Time shortening
Short circuit of the connector CN21 shortens the time as follows
1Fan control period: 30 seconds → 3 seconds
2Three-minutes time delay function : 3 minutes → 3 seconds
3Max. time of defrosting : 15 minutes → 15 seconds
4Defrost interval : 30 ~ 120 minutes → 3 ~ 12 seconds
5Compressor ON/OFF time for bypass valve ON/OFF : 30 minutes → 3 seconds
6Compressor ON time to start other functions : x minutes → x seconds
7Crankcase heater operation : 1 hour → 6 seconds
(6) Crankcase heater control
1With jumper wire J3
The crankcase heater is ON the moment the power is turned ON until the compressor starts, and then turns ON again
one hour after the compressor stops.
2Without jumper wire J3
The crankcase heater is ON the moment the power is turned ON until the compressor starts, and repeats 1-hour ON
again and 1-hour OFF, after the compressor stops.
