5.2.14 Connect the pipe to indoor unit and outdoor unit by brazing (Top discharge outdoor unit and Air Handler indo or units)

 Top discharge outdoor unit and air handler indoor units connections are copper-to-copper and should

be brazed with a phosphorous-copper alloy material such as Silfos-5 or equivalent. DO NOT use soft solder. The outdoor units have reusable service valves on both the liquid and vapor connections. The total system refrigerant charge is retained within the outdoor unit during shipping and installation. The reusable service valves are pr ovided to evacuate and charge per this instruct i on.

 Serious service problems can be avoided by taking adequate precautions to assure an internally clean

and dry system.

CAUTION: Dry nitrogen should always be supplied through the tubing while it is being brazed, because the temperature required is hi gh eno ugh to c aus e oxidat ion o f the c opper unless a n inert atmosphere is provide. The flow of dry nitrogen should continue until the joint has cooled. Always use a pressure regulator and safety valve to insure that only low pressure dry nitrogen is introduced into the tubing. Only a small flow is necessary to displace air and pr event oxidation.

 Precautions should be taken to prevent heat damage to service valve by wrapping a wet rag around it

as shown in following picture. Also, prot ect all paint ed sur faces, insulat ion, du ring braz ing. A fter braz ing cool joint with wet rag.

6.3 Drainage test

6.3.1 Water leakage test

After finishing the construction of drainage pipe system, fill the pipe with water and keep it for 24 hours to check whether there is leakage at joint section.

6.3.2 Water discharge test

1. Natural draina ge mode(t he indoor unit with outdoor drainage pump) Infuse above 600ml water through water test hole slowly into the water collector, observe whether the water can discharge through the transparent hard pipe at drainage out let.

2. Pump drainage mode

2.1 Disconnect the plug of water level swit ch, r emove the cover of water test hole and slow ly infuse about 2000ml water through the w ater test hole, be sure that the water will not touch the motor of drainage pump.

2.2 Power on and let the air conditioner operate for cooling. Check operation status of drainage pump, and then connect the plug of water level switch, check the operation sound of water pum p and observe whether the water can dischar ge t hr ough the transparent hard pipe at dra ina ge outlet. (In light of the

length of drainage pipe, wat er shall be discharged about 1 minute delayed)

2.3 Stop the operation of air conditioner, power off the power supply and put the cover of water test hole back to the original place.

a. After stopped the air condit ioner 3 minutes, check whether there is anyt hing a bnor mal. If drainage pipes

have not been distributed properly, over back-flow water shall cause the flashing of alarm indicator at remote-controlled receiving board a nd even water shall run over the water collector.

b. Continuously infusing water until water level alarmed, check whether the drainage pu mp co ul d

discharge water at once. If wat er level does not decline under warning water lev el 3 minutes later, it shall cause shutdown o f unit. When this situat ion ha ppen s, the normal startup only can be recovered by turning down power suppl y and eliminating accumulated water.

Note: Drain plug at the main water -containing plate is used for eliminat ing accumulated water in water-containing plat e w hen maintaining air conditioner fault. During normal operation, the plug shall be filled in to prevent leakage.

6.4 Insulation work of drainage pipe

Refer the introduction to t he i nsulat i on engineering parts.

Vacuum Drying and Leakage Checking

32 Installation

7. Vacuum Drying and Leakage Checking

7.1 Purpose of vacuum drying

 Eliminating moisture in sy st em to pr event the phenomena of ice-blockage and copper oxidation.

Ice-blockage shall cause abnormal operation of system, while copper oxid e shall damage compressor.

 Eliminating the non-condensable gas (air) in system to prev ent the components oxidizing, pressure

fluctuation and bad heat exchange during the operation of system.

7.2 Selection of vacuum pump

 The ultimate vacuum degree of v ac uum pump shall be -756mmHg or above.  Precision of vacuum pump shall reach 0. 02mmHg or above.

7.3 Operation procedure for vacuum drying

Due to different construction environment, two kinds of vacuum drying ways could be chosen, namely ordinary vacuum drying a nd special vacuum drying.

7.3.1 Ordinary vacuum drying

1. When conduct first vacuum drying, co nnect pressure gauge to the infusing mouth o f gas pipe and liquid pipe, and keep vacuum pump running for 1hour (vacuum degree of vacuum pump shall be reached

-755mmHg).

2 If the vacuum degree of vacuum pump could not reach -755mmHg after 1 hour of drying, it indicates

that there is moisture or leakag e in p ipeline system and need to go on with drying for half an hour.

3 If the vacuum degree of vacuum pump still could not reach -755mmHg after 1.5 hours of drying, check

whether there is leakage s our ce.

4 Leakage test: After the vacuum degree reac hes -755mmHg, stop vacuum drying and keep t he pressure

for 1 hour. If the indicator of vacuum gauge does not go up, it is qualified. If going up, it ind icat es that there is moisture or leak source.

7.3.2 Special vacuum drying

The special vacuum drying method shall be adopted when:

1. Finding moisture during flushing refrigerant pipe.

2. Conducting construction on rainy day, because r ain wat er m ight penetrated into pipeline.

3. Construction period is long, and rain wat er might penetrated into pipeline.

4. Rain water might penetrate into pipel ine during construction.

Procedures of special vac uum drying are as follows:

1. Vacuu m drying for 1 hour.

2. Vacuum damage, filling nitrogen to reach 0.5Kgf/cm2 .

Because nitrogen is dry gas, vacuum damage could achieve the effect of vacuum drying, but this method could not achieve drying thoroughly when there is too much moisture. Therefore, special attention shall be drawn to prevent the entering of water and the formation of condensate water .

3. Vacuu m drying again for half an hour.

If the pressure reached -755mmHg, start to pressure leakage test. If it can not r eached the value, repeat vacuum damage and vacuum drying again for 1 hour.

4 Leakage test: After the vacuum degree reac hes -755mmHg, stop vacuum drying and keep t he pressure

Additional refrigerant charge

Installation 33

8. Additional refrigerant charge

 After the vacuum drying pr ocess is carried out, the additional refrigerant c harge process need to be

performed.

 The outdoor unit is factory charged with refrig erant. The add itiona l refrigerant charge volume is decided

by the diameter and length of the l iq uid pipe between indoor and outdoor unit. Refer the follow ing formula to calculate the charge volume.

Diameter of liquid pipe (mm) Φ6.35 Φ9.52 Φ12.7 Formula V=20g×(L-5) V=40g×(L-5) V=60g×(L-5)

V: Additional refrigerant charge volume (g). L : The length of the liquid pipe (m).

Note:

 Refrigerant may only be charged after performed the vacuum drying process.  Always use gloves and glasses to protect your hands and eyes during the charge work.  Use electronic scale or flui d in fusion apparatus to weight refrigerant to be recharged. Be sure to avoid

extra refrigerant charged, it may cause liquid hammer of the compressor or protections.

 Use supplementing flexib l e pipe to connect refrigerant cylinder, pressure gauge and outdoor unit. And

The refrigerant should be c harged in liquid state. Before recharging, The air in the flexible pipe and manifold gauge should be exhausted.

 After finished refrigerant recharge process, check whether there is re fr igerant lea kage at the connection

joint part.(Using gas leakage detector or soap water to detect).
