Procedures
Operational Conditions
(Each of mentioned below is a standard opera-
tion time.
This may vary based on the installation cir-
cumstances, etc.)
(1) Turn to [Set-up Mode 1] (H1P : OFF).
H1P light is usually out. If H1P is
l
(BLINK) or
k
(ON), press “MODE” button (BS1) once
to go into [Set-up Mode 1].
(If H2P is lighted-on, check the defect codes with a remote controller to find out the cause.
Repair the defect part according to the list on the installation manual.)
Normal (H2P : OFF)
Defect (H2P : ON)
(2) After confirmed that it’s back in a normal condition, press “TEST” button (BS4) for longer
than 5 seconds.
It starts warming-up for the operation, and LED indication turns as right descriptions.
Close all the outside panels after putting back the service cover. (*2)
Startup and waiting operation for stable condi-
tions (approx.10 to 25 min.)
The outdoor and indoor unit fan is operated in
order to stabilize the refrigerant conditions.
And then the compressor starts operation.
Operation to check stop valve and mis-wiring
(approx. 5 min.)
(Contamination prevention is operated at the
same time.)
Operation to check refrigerant amount
(approx. 10 to 20 min.)
Check the refrigerant amount, and make
adjustments.
(Contamination prevention is operated at the
same time.)
Wh
en re-cha
rging is not required
(3) When re
-charging is required (*

1. • When the system stop operation, open the outside panel of the
EL.compo. box, then check the LED indications through the
inspection door.
If the LED indicate as right, connect the refrigerant tank to the
refrigerant re-charging port.
• Press the test operation button (BS4) for longer than 5 seconds
after connection of the refrigerant tank.
LED change indications, then re-start. (Use a refrigerant cylin-
der with sufficient amount of refrigerant.)
The system stop operation for warming-ups
before re-charging of refrigerant, then LED
indicate to connect the refrigerant tank (as on
the right).
Stand-by for a stable condition after the re-
start (approx. 1 to 3 min.).
2. • Open the valve of the refrigerant tank after LED indications turns
as right. (*3)
• Press the “TEST” button (BS4) once within 3 min. after opening
the valve. LED change indications.
• Immediately close the inspection door and all the outside pan-
els. (*2)
LED indicate to open the valve of the refriger-
ant tank (as on the right), and wait to press the
“TEST” button (BS4).
Operation for re-charging of refrigerant
(1~60 min.)
(Contamination prevention is operated at the
same time.)
If the malfunction code PA is displayed on the remote control-
ler, open the outside panel of the EL. comp.box, check the LED
indications through the inspection door.
The system stop operation due to insufficient
re-charging of refrigerant, then LED indicate to
replace the refrigerant tank (as on the right).
Automatic measuring of piping length
(approx.1 min.)
This is to check the length of field pipings.
(4) • After the system stop operation, open the outside panel of the EL.compo. box, then check
the LED indications through the inspection door.
• When completed properly.
• Disconnect the refrigerant tank.
• Close all the outside panels after putting back the inspection door.
• When abnormal stop.
• Malfunction code is displayed on the remote controller, check the malfunction code No.
Properly completed (H2P : OFF)
Abnormal stop due to the low pressure drops
(H2P: Blinking)
Defect determined (H2P : ON)
