B. Evacuation using self-provide cooling
agent of the installing worker
1. Joint the self-provide refrigerant pot to the
nozzle of the low-pressure valve.
2. Slacken the high-pressure valve
copper
nut cap.
3. Open the refrigerant pot
so that the
refrigerant can come into the tube.
4. After 15 seconds, you may feel cold at
,
tighten
and close
. If the high-pressure
valve has nozzle, the operation will be easier,
just open the inner valve to evacuate the air
in the tube.
5. Take off the tube and evacuate the excessive
refrigerant through the inner core.
E v a c u a t i o n w i t h
self-provide refrigerant
of the installing worker
or by vacuum pump.
Nameplate
(55g of refrigerant for
each meter of added
pipe length.)
1. Refer to section of vacuum pump or using refrigerant
jar.
2. Quantity of charging refrigerant to be proceeded
as per above table.
When relocate air conditioner, evacuate with
vacuum pump or refrigerant jar.
Open valve rod to the suitable are, do not try to
open it more widely.
Tighten valve cap with wrench or similar tools.
Tighten torque on valve cap.
1. Joint multiple meter charging tube
to single-way
valve nozzle of low-pressure valve.
2. Connect charging tube joint with vacuum pump.
3. Open up multiple meter low-pressure valve (L0)
handle and tighten the high-pressure handle
completely.
4. Start vacuum pump for evacuation.
5. After completion of evacuation, completely close
multiple meter low-pressure valve (L0) hardle and
stop vacuum pump.
Make sure if multiple meter is at -10 X 10 Pa (-
76cmHg) after evacuation for over 15 minutes.
6. Remove charging tube from single-way valve nozzle
of low-pressure valve.
7. Tighten low-pressure valve cap.
Note: It is not recommended to evacuate using
refrigerant in the outdoor unit, which will
result in refrigerant insuffient. If conditions
not allow, it is necessary to use the refrigerant in the
system and charge more 80g-100g refrigerant.
