8.2.7.12 Recycling and addition of A/C refrigerant

Operating efficiency and service life of the A/C system depend on the chemical stability of the refrigerating
system. When the refrigeration system is polluted by foreign bodies (such as dust, air or moisture), the pollutant
shall change the stability of the refrigerant and 100PG compressor oil, and can affect the relationship between
pressure and temperature, reduce the working efficiency and may result in internal corrosion and abnormal
element wear, The following methods are operated for ensuring the chemical stability of the system:

1. Before opening the joint, first remove oil stain from joint and position around joint to reduce posibility of

small little of oil stain entering into system.

2. After disconnection of joint, immediately seal two sides of joint with cap, plug or adhesive tape, to prevent

oil stains, foreign matters and wet air from entering into it.

3. Keep all tools clean and dry, including manifold pressure components and all replacing components.

4. Use clean and dry carrying device and container to fill 100PG refrigerant oil, make sure that refrigerant oil is

free from wet effect.

5. During operation, reduce the time for which the inside of the A/C is exposed to the air as possible.

6. The A/C system must be air exhausted once again and filled with refrigerant after being exposed to the air.

All service parts are dry and sealed prior to delivery, Open these sealed parts only being about to install.
Prior to unpackaging, all parts should be at room temperature, moisture should be prevented from being
condensed on the parts and then entering the system and all parts should be enclosed as soon as possible.

Emission of the A/C system as well as the adding, emptying and filling procedures of lubricating oil

Warning!

See "Warnings for intake of R-134a" in "Warning and precaution ". Other health and safety information can be
obtained from the refrigerant and lubricating oil manufacturer.

Warning!

See "Warnings for goggles and gloves" in "Warning and precaution ".

The filling machine is connected once to complete the emission, emptying and refilling procedure of the A/C
system. The refrigerant is filtered in the course of recyclinging and emptying, thereby making sure that the
refrigerant filled into the A/C system is clean and dry.

1. It is prohibit to fill R-134a system by oil filling

machine. The refrigerant and the refrigerant oil of
the two systems are not compatible and must not
be mixed; even a small amount is also not
allowed because the equipment may be damaged
by mixing with the residual refrigerant.

2. It is strictly forbidden to use reducing joint, to

ensure sealing performance inside system.

Installation and maintenance of the filling machine

There are various types of filling machines; all filling machines perform various tasks, such as A/C system
emission, refrigerant recycling, system emptying, quantitative addition of refrigerant oil and quantitative refilling

of refrigerant, etc. see filling machine operation manual to master the initial installation and maintenance
procedures.

Control panel function

Operator may control and monitor the operation process with the control button and indicator lamp on the filling
machine. See the instruction for use of the filling machine for details. The instruction shall include the following
content:

1. Main power supply switch: main power supply switch provided power supply with control panel.

2. Screen: screen shows time of vacuum pumping set by programming and weight of refrigerant to be refilled.

See the manufacturer's Instructions for learning detailed programming information.

3. Manifold pressure gauge on low-pressure side: this gauge shows pressure on low pressure side of the system.

4. Manifold pressure gauge on high-pressure side: this gauge shows pressure on high-pressure side of the

system.

5. Control panel: it accommodates various buttons and knobs for controlling various functions.

6. Low pressure side valve: this valve is used for connecting the low pressure side of the A/C system with the

filling machine.

7. Humidity indicator: this indicator indicates whether the refrigerant is humidified.

8. High pressure side valve: this valve is used for connecting the high pressure side of the A/C system with the

filling machine.

Refrigerant Recycling

Notes:

The refrigerant tank specially designed for the filling machine is only used. over-filling prevention mechanism of
the filling machine is corrected specially for the refrigerant tank. However, the refrigerant tank valve is also
manufactured specifically for the device.

1. Connect high-pressure side hose with quick coupler to high-pressure side coupler of vehicle A/C system.

2. Turn on high pressure side connector valve

3. Connect low-pressure hose with quick coupler to low-pressure coupler of vehicle A/C system.

4. Open low-pressure joint valve.

Notes:

If no refrigerant in the system, stop the Recycling operation immediately; otherwise, inhale into the Recycling
tank.

5. Check the high-pressure side and low-pressure side pressure gauges on the filling machine control panel to

ensure the A/C system is under pressure. If no pressure, the system has no recyclable refrigerant.

6. Open the high pressure side and low pressure side valves.

7. Open the gas and fluid valves on the refrigerant tank.

8. Thoroughly remove the refrigerant oil from the oil-liquid separator.

9. Closed oil drain valve

10. Connect filling machine to suitable power supply outlet.

11. Switch on main power supply switch.

Notes:

Forbid mixing of old refrigerant oil and new refrigerant oil together. Old oil may be precipitated with aluminum
or mixed with other foreign materials. Be sure to use new refrigerant oil when refilling the A/C system, correctly
scrap the used refrigerant oil.
