REFRIGERANT CHARGING

Installation of Manifold Gauge

1. Close both high/low pressure hand valves of

manifold gauge before installation of gauge to the
charging valve.

2. Both high/low pressure hand valves of manifold

gauge connect the appropriate charging valve.
Tighten the hose nuts by hand.

Discharging Refrigerant

1. Connect the manifold gauge to the charging valve.

2. Place the free end of the center hose in a shop

towel.

3. Slowly open the high pressure hand valve and

discharge refrigerant.

Notice: If refrigerant is allowed to escape too fast,
compressor oil will be drawn out of the system.

4. Check whether the shop towel gets wet in oil and

if wet, close the hand valve.

5. After the high pressure gauge reading drops below

3.5 kg/cm

2

, slowly open the low pressure valve.

6. When both high and low pressure gauges reading

drops to 0 kg/cm

2

, discharging is completed.

Evacuating Refrigeration System

Notice: The unit tank must contain a sufficient amount
of R-134a refrigerant for charging. Check the amount
of refrigerant in the tank. If there is less than 3.6 kg
(8 pounds) of refrigerant, add new refrigerant to the
tank.

1. Verify that the high-side and the low-side hoses

are connected to the A/C system. Open both the
high-side and the low-side valves on the unit’s
control panel.

2. Open both the gas and the liquid valves on the

tank.

instructions for the charging station in use. It is
necessary to evacuate the system before
recharging it with new or recycled refrigerant.

3. Start the vacuum pump and begin the evacuation

process. Non-condensable gases (mostly air) are
vented from the tank automatically during the
recycling process. The pressure being released
may be heard.

4. Check for leaks in the system. Refer to the

manufacturer’s instructions for the charging
station in use.

Check for Refrigerant Leaks

1. Connect the center hose of the gauge to the

refrigerant tank.

2. Open the high pressure valve of the gauge to

charge with refrigerant gas.

3. Charge until the low pressure gauge reads 1.0 kg/cm

2

and close the valve.

4. Using a gas leak detector, check the system for

leaks.

5. If any leak is found, replace O-ring or repair the

faulty connection.

How to Use the Tap Valve

1. Rotate the handle counterclockwise fully before

connecting the valve to the refrigerant tank.

2. Rotate the disk counterclockwise fully.

3. Connect the center hose to the valve fitting and

then rotate the disk clockwise fully by hand.

4. Rotate the handle clockwise to drill the sealed

hole.

5. Remove the hose nut securing the center fitting

of the manifold gauge and then tighten the nut
again in a few seconds.

Charging Refrigerant

Charging for Gas

1. Connect the tap valve to the refrigerant tank.

2. Open the low pressure and adjust the low-side

reading below 4.2 kg/cm

2

.

3. Place the refrigerant tank in the warm water

(40 °C) and keep the gas pressure in the refrigerant
tank higher than the gas pressure in the charging
valve.

4. Run the engine at high speed and operate A/C

system.

Notice: Place the refrigerant tank on the flat floor
to protect the liquid refrigerant from coming

compressor’s damage.

5. Charge the specified amount to the charging valve

and close the low pressure valve.

Notice:

•

If the charging speed is low, it’s more efficient
to place the refrigerant tank in the warm water
(40 °C). But the temperature should keep below
(52 °C) at any situation.

•

Be careful not to contact the heating device or
material.

Charging for Liquid

Notice:

•

Do not operate when charging the system through
the high-side rpessure.

•

Do not open the low pressure valve when charging
the system by the liquid refrigerant.

1. Tighten both high pressure and low pressure

completely before evacuating the charging valve.

2. Connect the tap valve of the refrigerant tank.

3. Open the high pressure valve and turn the

refrigerant tank upside down.
