System Diagram 5.1 System Diagram for Cooling-and-Heating Unit

Capillary

4-way valve

Evaporator Condenser

Cooling Gas-liquid separator Heating Compressor

Switch on the power to start the unit. Low-pressure refrigerant vapor from evaporator is absorbed into the compressor, where it is compressed into high-temp. and high-pressure gas. The gas refrigerant is then diverted to condenser, where it is liquidized after heat exchange with outdoor air. After that, the liquidized refrigerant flows through capillary for decrease of temperature and pressure and then enters into evaporator, where it becomes low-temp. and low-pressure refrigerant vapor after heat exchange with indoor air to be regulated. This process is repeated in cycle to achieve the purpose of cooling. (Under heating mode, the 4-way valve will change the flow of refrigerant, so that the condenser absorbs heats and the evaporator gives out heats, thus to achieve the purpose of heating).

Using Vacuum Pump 1. Connect the flexible charge tube of the manifold valve with the charge mouth of the low pressure valve (both the high

and low pressure valves must be closed). 2. Connect the flexible charge tube with the vacuum pump. 3. Put the low pressure (Lo) handle of the manifold valve to the complete open position. 4. Start the vacuum pump to operate vacuum pumping. Now open the connecting pipe nut of the low pressure valve

slightly to check if air is entering. 5. After the vacuum pumping is completed, put the low pressure (Lo) handle of the manifold valve to the complete close

position to stop the vacuum pump (after operating vacuum pumping for above 15 minutes, confirm if the reading of multi-use meter is -10×105pa (-76cmHg)).

6. Completely open the high and low pressure valves. 7. Disconnect the flexible charge tube from the charge mouth of

the low pressure valve. 8. Tighten the low pressure valve cap (refer to Figure 10). ③ Electrical Cable Layout 1. Before connections, refer to the part voltages specified on the nameplate, and then carry out line connections

according to the electrical diagram attached on the unit. Do not connect high voltage cables with low voltage cables. 2. The air-conditioning unit must have special voltage cable and must be equipped with power leakage switch and air

switch so as to deal with the occurrence of overload. 3. The air-conditioning unit must be grounded to avoid harm as a result of insulation failure. 4. All lines must be correctly connected according to the electrical diagrams attached to the unit. Wrong connections

may cause abnormal operation or damage of the air-conditioning unit. Caution； All electrical line layouts must be carried out by professional technicians. Wrong line layout may cause electric shock or fire accident. ④Connection of Power Cables 1. Remove the front side plate (Figure 11). 2. Drill through the cable-cross hole at the outdoor unit and attach the cable-cross loop. 3. Pull all cables through the cable-cross loop hole. 4. Carry out line connections according to the electrical diagram for the outdoor unit side. Ensure the connections are

secure. 5. Use wire-pressed clamps to press and secure the cables. Caution : 1. There must be reliable grounding. 2. The connections must be reliable. 3. The connection points shall not subject to tension. 4. Other cables must have reliable connections with their corresponding terminals. 5. For single phase, connect the two 3-core rubber covered cables to the corresponding terminals. 6. Cooling Only Type : (3-Phase) Connect the 3-core rubber covered cable to the L, N1 terminals of the 8-bit terminal board. Connect the 5-core rubber covered cable to the L1, L2, L3 and N terminals of the 8-bit terminal board. Heating and Cooling Type : (3-Phase) Connect the 5-core rubber covered cable to the 5-bit terminal board
