undesirableeffectsasbelow:
Pressureinthe systemrises.
Operatingcurrent rises.
Cooling or heatingefficiencydrops.
Moistureintherefrigerantcircuitmay
freezeand blockcapillarytubing.
Watermaylead tocorrosion ofpartsinthe
refrigerant system.
Therefore,the indoorunitsand thepipes
between indoorand outdoorunitsmustbe leak
tested and evacuated toremovegas and
moisturefromthe system.
Gas leakcheck(Soap water method):
Applysoap wateroraliquidneutral
detergenton the indoorunitconnections or
outdoorunitconnectionsby asoft brush to
checkforleakage ofthe connecting pointsof
the piping.Ifbubbles comeout, the pipes have
leakage.
1.Airpurging withvacuumpump
1)Completelytighten theflarenutsofthe
indoorandoutdoorunits,confirmthatboth
the 2-wayand 3-wayvalves aresettothe
closed position.
2)Connectthe charge hosewiththe push pin
ofhandlelotothe 3-wayvalves gas service
port.
3)Connectthe charge hose ofhandlehi
connectiontothe vacuumpump.
4) Fullyopen the handle Lo of the manifold
valve.
5) Operate the vacuumpump to evacuate.
6) Make evacuation for 30 minutes and check
whether the compoundmeter indicates
-0.1Mpa. Ifthe meter does not indicate
-0.1Mpa after pumping 30 minutes, it
should be pumped 20 minutes more. Ifthe
pressure can’tachieve -0.1Mpa after
pumping 50 minutes, please checkifthere
are some leakage points.
Fullyclose the handleLo valveofthe manifold
valveand stopthe operation ofthe vacuum
pump.Confirmthatthe gauge needledoesnot
move(approximately5minutes afterturning off
the vacuumpump).
7)Turnthe flarenutof the 3-wayvalves about
45°counterclockwise for6or7seconds
after the gas
coming out, then tighten the flarenutagain.
Makesurethe pressuredisplayinthe pressure

4)Operatethe airconditioneratthe cooling
mode.
5)Open the valves (Lowside)onthe chargeset
and charge the systemwithliquidrefrigerant.
6).When the electronicscaledisplaysthe proper
weight(refertothe table), disconnectthe charge
hose fromthe 3-wayvalve’sservice port
immediatelyand turnoffthe airconditionerbefore
disconnecting the hose.
7). Mountthe valvestemcapsand theservice

2). Purge the air fromthe charge hose
Open the valveatthe bottomofthe cylinder
and pressthe checkvalveon the charge setto
purge the air(be carefulofthe liquid
refrigerant).
3)Putthe charging cylinderontothe electronic
scaleand recordthe weight.
4). Open the valves (Lowside)on the chargeset
and charge the systemwithliquidrefrigerant
Ifthe systemcannotbe charge withthe specified
amountofrefrigerant, orcan be charged witha
littleatatime(approximately150g each time),
operating theairconditionerinthe cooling cycle;
however,one timeisnotsufficient, wait
approximately1minuteand then repeatthe
procedure.
5).When the electronicscaledisplaysthe proper
weight, disconnectthe chargehosefromthe
