1. AIR PURGING (INSTALLATION)
l Required tools: hexagonal wrench, adjustable wrench, torque wrenches, wrench
to hold the joints, and gas leak detector.
l The additional gas for air purging has been charged in the outdoor unit. However,
if the flare connections have not been done correctly and gas leaks, a gas cylin-
der and the charge set will be needed.
l The air in the indoor unit and in the piping must be purged. If air remains in the
refrigerant pipes, it will affect the compressor, reduce the cooling and heating
capacity, and could lead to a malfunction.
l Be sure to use a torque wrench to tighten the service port cap (after using the
service port), so that it prevents the gas leakage from the refrigeration cycle.
l Caution: Do not leak the gas in the air during air purging.
l Air purging procedure
F Recheck the piping connections.
F Open the valve spindle of the 2-way valve counter-clockwise proximately
90°°,wait 10 seconds, and then set it to closed position. Be sure to use a hex-
agonal wrench to operate the spindle.
36
Model No: AC -S24CK_S24HK
Version 1.0
F Check the flare connections for refrigerant gas leakage.
F Purge the air from the system. Set the 2-way valve to the open position and
remove the cap from the 3-way valve’s service port. Using the hexagonal wrench
to press the valve core pin, discharge for three seconds and then wait for one
minute. Repeat this three times.
F Use torque wrench to tighten the service port cap to a torque of 1.8kg.cm.
F Set the 3-way valve to the back seat.
F Mount the valve caps to the 2-way and 3-way valves.
F Check for gas leakage. At this time, especially check for gas leakage from the
2-way and 3-way valve’s caps, and from the service port cap.
l Caution: If gas leakage is discovered, take the following measures.
F If the gas leakage stops when the piping connections are tightened fur-
ther ,continue working.
F If the gas leakage does not stop when the piping connections are tightened,
repair the location of the leakage, discharge all of the gas through the service
port, and then recharge with the specified amount of gas from a gas cylinder.

ening the flare nut on the 2-way valve approximately 45°°for 3 seconds, then
38
Model No: AC -S24CK_S24HK
Version 1.0
closing it for 1 minute. Repeat 3 times.
F After purging the air, use a torque wrench to tighten the flare nut on the 2-way
valve.
l Check the flare connections for gas leakage.
l Disconnect the charge set and the gas cylinder, and set the 2-way and 3-way
valves to the open position.
F Be sure to use a hexagonal wrench to operate the valve spindles.
l Mount the valve caps and the service port cap.
F Use torque wrench to tighten the service port cap to a torque of 1.8kg.m.

4. BALANCE REFRIGERANT OF THE 2-WAY, 3-WAY VALVES (GAS LEAKED)
l Confirm that both the 2-way and 3-way valves are set to the back seat.
l Connect the charge set to the 3-way valve’s service port.
39
Model No: AC -S24CK_S24HK
Version 1.0
F Leave the valve on the charge set closed.
F Connect the charge hose with the push pin to the service port.
l Open the valve (Low side)on the charge set and discharged the refrigerant until
the gauge indicates 0kg/cm
2
.g.
F If there is no air in the refrigerant cycle (the pressure when the air conditioner is
not running is higher than 1 kg/cm
2
.g),discharge the refrigerant until the gauge
indicates 0.5 to 1 kg/cm
2
.g.If this is the case, it will not be necessary to apply an
evacuation.
F Discharge the refrigerant gradually. If it is discharged too suddenly, the refrigera-
tion oil will also be discharged.
5. EVACUATION (ALL AMOUNT OF REFRIGERANT LEAKED)
l Connect the vacuum pump to the charge set’s center hose.
l Evacuating for approximately one hour.
F Confirm that the gauge needle has moved toward -76cmHg (vacuum of 4
mmHg or less)
40
Model No: AC -S24CK_S24HK
Version 1.0
l Close the valve (Low side) on the charge set, turn off the vacuum pump, and
confirm that the gauge needle does not move (approximately 5 minutes after
turning off the vacuum pump).
l Disconnect the charge hose from the vacuum pump.
F If the vacuum pump oil becomes dirty or depleted, replenish as needed.
6. GAS CHARGING (AFTER EVACUATION)
l Connect the charge hose to the charging cylinder.
F Connect the charge hose which you disconnected from the vacuum pump to the
valve at the bottom of the cylinder.
F If you are using a gas cylinder ,also use a scale and level the cylinder so that the
system can be charged with liquid.
l Purge the air from the charge hose.
F Open the valve at the bottom of the cylinder and press the check valve on the
charge set to purge the air.(Be careful of the liquid refrigerant).The procedure is
the same if using a gas cylinder.
l Open the valve (Low side on the charge set) and charge the system with liquid
41

Version 1.0
refrigerant.
F If the system can not be charged with the specified amount of refrigerant, it can
be charged with a little at a time (approximately 150g each time) while operating
the air conditioner in the cooling cycle. However, one time is not sufficient, wait
approximately 1 minute and then repeat the procedure (pumping down pin).
F This is different from previous procedures. Because you are charging with liquid
refrigerant from the gas side, absolutely do not attempt to charge with larger
amounts of liquid refrigerant while operating the air conditioner.
l Immediately disconnect the charge hose from the 3-way valve’s service port.
F Stopping partway will allow the gas to be discharged.
F If the system has been charged with liquid refrigerant while operating the air
conditioner before disconnecting the hose.
l Mount the valve caps and service port cap.
F Use torque wrench to tighten the service port cap to a torque of 1.8kg.m.
F Be sure to check for gas leakage.
