11-2-1 Refrigerant Charging Operation Procedure
[Check operation]
Procedures
Operational Conditions
(Each of mentioned below is a standard
operation time. It could change depending on
the installation circumstances, etc.)
Operation to check refrigerant amount 1
Turn on the indoor fan to keep the condition of
refrigerant stable.
(It may take nearly 30 min., depending on the
refrigerant condition.)
Operation to check stop valve and mis-wiring
(approx.5 min.)
(Contamination prevention is operated at the
same time.)
(1) Turn to [Set-up Mode 1] (H1P : light-out)
H1P light is usually out. If H1P is
l
(blinking) or
k
(lighted-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 (1) 11.)
(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 (in approx. 50 seconds).
Close all the outside panels after putting back the service cover. (*2)
• When the system stop operation, open the outside panel of the EL.
Compo. box, then check the LED indications throngh 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
cylinder with sufficient amount of refrigerant.)
Operation to check refrigerant amount 2
Check the refrigerant amount, and make adjustments.
(Contamination prevention is operated at the
same time.)
The system stop operation for warming-ups
before re-charging of refrigerant, then LED
indicate to connect the refrigerant tank (as on
the right).
LED indicate to open the valve of the refrigerant
tank (as on the right) in approx. 6 min. after the
re-start.
Operation for re-charging of refrigerant (1~ 60 min.)
(Contamination prevention is opearted at the same time.)
Operation for contamination prevention (30 ~ 60 min.)
It takes max. 1 hour.
The system stop operation upon completion of
re-charging of refrigerant, then LED indicate to
close the valve of the refrigerant tank (as on the
right).
The system stop operation due to shortage of
refrigerant re-charging amount, then LED
indicate to replace the refrigerant tank (as on the
right).
Stand-by for a stable condition after the re-start.
normal (H2P : light-out)
defect (H2P : light-on)
When re-charging is not required
(3)
When re-charging is required .(*4)
1)
•
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
panels.
(*2)
2)
3) •
Close the valve of the refrigerant tank
when the system stop
operation.
• Open the outside panel of the EL. compo. box, then check the LED
indications through the inspection door.
• If LED shows LED indications to [close] the valve of refrigerant tank
(as right-upper side), re-charging operation is completed.
Press the test operation button (BS4) once again for longer then
5 seconds.
LED change indication, then re-start.
Immediately close the inspection door and all the outside panels.
(*2)
Stand-by for a stable condition after the re-start.
Defect determined (H2P : light-on)
Properly completed (H2P : light-out)
Automatic measuring of piping length. (Approx.10 min.)
This is to check the length of field pipings.
Final check of the refrigerant amount is done at
the same time.
• After the system stop operation, remove 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.
