(*3) Check for solenoid valve of all outdoor units in a line (For multiple
outdoor unit system)
a)
Clogging check for SV3A
valve
•
While outdoor unit is operating, set up SW01/02/03 = [2] [1] [3] (7-segment display [Hr] [... ... ...]), and
push SW04 for 2 seconds or more.
•
Set up SW02 = [6], and turn on SV3A
valve. (7-segment display [Hr] [... 3
A])
•
If temperature is low at secondary side of the valve or it does not change, clogging of valve or check
valve is considered. ((1) in the figure.)
b)
Leakage check for SV3C valve
•
While outdoor unit is operating, set up SW01/02/03 = [2] [1] [3] (7-segment display [Hr] [... ... ...]), and
push SW04 for 2 seconds or more.
•
Set up SW02 = [8], and turn on SV3C valve. (7-segment display [Hr] [... 3 C])
•
If temperature does not change (up), clogging of valve or strainer is considered. ((2) in the figure.)
(*4)
a)
Clogging check for oil-equalization circuit
•
Drive the outdoor unit. (Drive all compressors in the unit.)
•
After driving for 10 minutes or more, check whether temperature of
TK1,
TK2 sensors and
temperature of oil-equalization circuit capillary ((8) in the figure) has increased.
(Criterion)
TK1,
TK2=Td1,
Td2
temperature
- Approx. 10 to 30°C
Oil-equalization capillary tubes should be higher suf
ficiently than outside air temperature and suction
temperature.
•
If temperature is low
, a malfunction on check valves or clogging of capillary
, strainer or distributor is
considered. Repair the defective parts.
