Every time you connect it, first loosen the nuts at the part of stop value, then connect the flare pipe immediately (in 5 minutes). If the nuts have been loosened for a long time, dusts and other impurities may enter the pipe system and may cause malfunction later. So please expel the air out of the pipe with refrigerant before connection. Expel the air after connecting the refrigerant pipe with the indoor unit and the outdoor unit. Then fasten the nuts at the repair-points. 1.2. Locate The Pipe a. Drill a hole in the wall (suitable just for the size of the wall conduit), then set on the fittings such as the wall conduit and its cover. b. Bind the connecting pipe and the cables together tightly with binding tapes. Do not let air in, which will cause water leakage by condensation. c. Pass the bound connecting pipe through the wall conduit from outside. Be careful of the pipe allocation to do no damage to the tubing. 1.3. Connect the pipes. 1.4. Then, open the stem of stop values of the outdoor unit to make the refrigerant pipe connecting the indoor unit with the outdoor unit in fluent flow. 1.5. Be sure of no leakage by checking it with leak detector or soap water. 1.6. Cover the joint of the connecting pipe to the indoor unit with the soundproof / insulating sheath (fittings), and bind it well with the tapes to prevent leakage. 92 GD Chigo Heating & Ventilation Equipment Co., Ltd. R410A50Hz Universal Outdoor Series Technical Manual 2 Vacuum Dry and Leakage Checking 2.1 Vacuum Dry: use vacuum pump to change the moisture (liquid) into steam (gas) in the pipe and discharge it out of the pipe to make the pipe dry. Under one atmospheric pressure, the boiling point of water(steam temperature) is 100℃. Use vacuum pump to make the pressure in the pipe near vacuum state, the boiling point of water falls relatively. When it falls under outdoor temperature, the moisture in the pipe will be vaporized. 2.2 Vacuum dry procedure There are two methods of vacuum dry due to different construction environment: common vacuum dry, special vacuum dry. ①. Common vacuum dry procedure  Vacuum dry (for the first time)---connect the all-purpose detector to the inlet of liquid pipe and gas pipe, and run the vacuum pump more than two hours (the vacuum pump should be below -755mmHg)  If the pump can’t achieve below -755mmHg after pumping 2 hours, moisture or leakage point will still exist in the pipe. At this time, it should be pumped 1 hour more.  If the pump can’t achieve -755mmHg after pumping 3 hours, please check if there are some leakage points.  Vacuum placement test: place 1 hour when it achieves -755mmHg, pass if the vacuum watch shows no rising. If it rises, it shows there’s moisture or leakage point.  Vacuuming from liquid pipe and gas pipe at the same time.  Sketch map of common vacuum dry procedure. 93 GD Chigo Heating & Ventilation Equipment Co., Ltd. R410A50Hz Universal Outdoor Series Technical Manual ②. Special vacuum dry procedure  This vacuum dry method is used in the following conditions:  There’s moisture when flushing the refrigerant pipe.  Rainwater may enter into the pipe.  Vacuum dry for the first time ······2h pumping ③. Vacuum destroy for the second time ······Fill nitrogen to 0.5Kgf/cm 2 Because nitrogen is for drying gas, it has vacuum drying effect during vacuum destroy. But if the moisture is too much, this method can’t dry thoroughly. So, please pay more attention to prevent water entering and forming condensation water. ④. Vacuum dry for the second time······1h pumping Determinant: Pass if achieving below -755mmHg. If -755mmHg can’t be achieved in 2h, repeat procedure ③ and ④. ⑤. Vacuum placing test ······1h ⑥. Sketch map of special vacuum dry procedure 94 GD Chigo Heating & Ventilation Equipment Co., Ltd. R410A50Hz Universal Outdoor Series Technical Manual 3 Additional Refrigerant Charge Caution ● Refrigerant cannot be charged until field wiring has been completed. ● Refrigerant may only be charged after performing the leak test and the vacuum pumping. ● When charging a system, care shall be taken that its maximum permissible charge is never exceeded, in view of the danger of liquid hammer. ● Charging with an unsuitable substance may cause explosions and accidents, so always ensure that the appropriate refrigerant is charged. ● Refrigerant containers shall be opened slowly. ● Always use protective gloves and protect your eyes when charging refrigerant. The outdoor unit is factory charged with refrigerant. Calculate the added refrigerant according to the diameter and the length of the liquid side pipe of the outdoor unit/indoor unit R(g) D(mm) L(m) Less than 5m (One-way) Added Refrigerant When Over 5m(One-way) φ6.4 Φ9.5 Φ12.7 — — — 30g/m×(L-5) 65g/m×(L-5) 120g/m×(L-5) Remark: R (g): Additional refrigerant to be charged L (m): The length of the refrigerant pipe (one-way) D (mm): Liquid side piping 95 GD Chigo Heating & Ventilation Equipment Co., Ltd. R410A50Hz Universal Outdoor Series Technical Manual 4 Water Drainage 4.1 Gradient and Supporting 4.1.1 Keep the drainpipe sloping downwards at a gradient of at least 1/100. Keep the drainpipe as short as possible and eliminate the air bubble. 4.1.2 The horizontal drainpipe should be short. When the pipe is too long, a prop stand must be installed to keep the gradient of 1/100 and prevent bending. Refer to the following table for the specification of the prop stand. Hard PVC pipe Diameter Distance between the prop stands 25~40mm 1~1.5m 4.1.3. Precautions ① The diameter of drainpipe should meet the drainage requirement at least. ② The drainpipe should be heat-insulated to prevent atomization. ③ Drainpipe should be installed before installing indoor unit. After powering on, there is some water in water-receiver plate. Please check if the drain pump can operate correctly. ④ All connection should be firm. ⑤ Wipe color on PVC pipe to note connection. ⑥ Climbing, horizontal and bending conditions are prohibited. ⑦ The dimension of drainpipe can’t less than the connecting dimension of indoor drainpipe. ⑧ Heat-insulation should be done well to prevent condensation. ⑨ Indoor units with different drainage type can’t share one convergent drainpipe. 4.2 Drainpipe Trap 4.2.1. If the pressure at the connection of the drainpipe is negative, it needs to design drainpipe trap. 4.2.2. Every indoor unit needs one drainpipe trap. 4.2.3. A plug should be designed to do cleaning. 96 50cm 50cm P l u g GD Chigo Heating & Ventilation Equipment Co., Ltd.

R410A50Hz Universal Outdoor Series Technical Manual 4.5 Drainage test 4.5.1Drainage without drain pump After finishing drainpipe installation, pour some water into the water receiver plate to check if the water flows smoothly. 4.5.2 Drainage with drain pump ① Poke the Water Level Switch, remove the cover, use water pipe to pour 2000ml water into the water receipt plate through the water inlet. ② Turn on the power to Cooling operation. Check the pump’s operation and switch on the Water Level Switch. Check the pump’s sound and look into the transparent hard pipe in the outlet at the same time to check if the water can discharge normally. ③ Stop the air conditioner running, turn off the power, and put back the cover.  Stop the air conditioner. After 3 minutes, check if it has abnormity. If the collocation of drainpipes is illogical, the water will flow back overfull, which will cause the alarm lamp flashes, even overflow from the water receipt plate.  Keep on pouring water until it gives an alarm signal for high water level, check if the pump drains water at once. If the water level can’t fall below the alarmed water level after 3 minutes, the air conditioner will stop. Turn off the power and drain the remained water, and then turn on the air conditioner. Note: the drain stuff in the main water receipt plate is for maintenance. Stuff up the drain stuff to prevent water leakage. 98 GD Chigo Heating & Ventilation Equipment Co., Ltd.
