INSTLATION DETAILS

Version - 2 32 HKD DCI

8.4 Installation for the first time

Air and moisture in the refrigerant system have
undesirable effects as below:

● Pressure in the system rises.

● Operating current rises.

● Cooling or heating efficiency drops.

● Moisture in the refrigerant circuit may

freeze and block capillary tubing.

● Water may lead to corrosion of parts in the
refrigerant system.

Therefore, the indoor units and the pipes
between indoor and outdoor units must be leak
tested and evacuated to remove gas and
moisture from the system.

Gas leak check (Soap water method):

Apply soap water or a liquid neutral
detergent on the indoor unit connections or
outdoor unit connections by a soft brush to
check for leakage of the connecting points of
the piping. If bubbles come out, the pipes have
leakage.

8.4.1 Air purging with vacuum pump

1) Completely tighten the flare nuts of the

indoor and outdoor units, confirm that both
the 2-way and 3-way valves are set to the
closed position.

2) Connect the charge hose with the push pin

of handle lo to the 3-way valves gas service
port...

3) Connect the charge hose of handle hi

connection to the vacuum pump.

4) Fully open the handle Lo of the manifold
valve.

5) Operate the vacuum pump to evacuate.

6) Make evacuation for 30 minutes and check
whether the compound meter indicates

-0.1Mpa. If the meter does not indicate

-0.1Mpa after pumping 30 minutes, it
should be pumped 20 minutes more. If the
pressure can’t achieve -0.1Mpa after
pumping 50 minutes, please check if there
are some leakage points.

Fully close the handle Lo valve of the manifold
valve and stop the operation of the vacuum
pump. Confirm that the gauge needle does not
move (approximately 5 minutes after turning off
the vacuum pump).

7) Turn the flare nut of the 3-way valves about
45° counterclockwise for 6 or 7seconds
after the gas

Coming out, then tighten the flare nut again.
Make sure the pressure display in the pressure
indicator is a little higher than the atmosphere
pressure. Then remove the charge hose from
the 3 way valve.

8) Fully open the 2 way valve and 3 way valve
and securely tighten the cap of the 3 way
valve.

8.4.2 Air purging by refrigerant

Procedure:

1). Confirm that both the 2-way and 3-way valves

are set to the closed position.

2). Connect the charge set and a charging

INSTALLATION DETAILS

HKD DCI 33 Version - 2

cylinder to the service port of the 3-way valve.

3). Air purging.
Open the valves on the charging cylinder and the
charge set. Purge the air by loosening the flare
nut on the 2-way valve approximately 45’ for 3
seconds then closing it for 1 minute; repeat 3
times.
After purging the air, use a torque wrench to
tighten the flare nut on the 2-way valve.

4). Check the gas leakage.
Check the flare connections for gas leakage.

5). Discharge the refrigerant.
Close the valve on the charging cylinder and
discharge the refrigerant by loosening the flare
nut on the 2-way valve approximately 45’ until the
gauge indicates 0.3 to 0.5 Mpa.

6). Disconnect the charge set and the charging
cylinder, and set the 2-way and 3-way valves to
the open position.
Be sure to use a hexagonal wrench to operate the
valve stems.

7). Mount the valve stems nuts and the service
port cap.
Be sure to use a torque wrench to tighten the
service port cap to a torque 18N·m.
Be sure to check the gas leakage.

8.4.3 Adding the refrigerant if the pipe
length >5m

Procedure:

1). Connect the charge hose to the charging

cylinder, open the 2-way valve and the 3-way
valve.
Connect the charge hose which you
disconnected from the vacuum pump to the
valve at the bottom of the cylinder. If the

refrigerant is R410A, make the cylinder bottom
up to ensure the liquid charge.

2). Purge the air from the charge hose.
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).

3) Put the charging cylinder onto the electronic
scale and record the weight.

4) Operate the air conditioner at the cooling
mode.

5) Open the valves (Low side) on the charge set
and charge the system with liquid refrigerant.

6).When the electronic scale displays the proper
weight (refer to the table), disconnect the charge
hose from the 3-way valve’s service port
immediately and turn off the air conditioner before
disconnecting the hose.

7). Mount the valve stem caps and the service
port
Use torque wrench to tighten the service port
cap to a torque of 18N.m.
Be sure to check for gas leakage.

8.5 Adding the refrigerant after running the
system for many years

Procedure:

1). Connect the charge hose to the 3-way service

port, open the 2-way valve and the 3-way valve.
Connect the charge hose to the valve at the
bottom of the cylinder. If the refrigerant is
R410A, make the cylinder bottom up to ensure
liquid charge.

2). Purge the air from the charge hose.

Open the valve at the bottom of the cylinder
and press the check valve on the charge set to
