Logic of controlling compressor and fan of condensing units ASE-xxAH 1, For 18,24,36K units, All the outdoor fan have a outdoor fan with fixed speed. Normally the outdoor fan runs with the compressor. The outdoor fan starts when the compressor starts, and stops when the compressor stops. And their running status are determined by the difference between indoor and setting temprature.
2, For 48K and 60K units, Some are with single fan and some are with twin fans, For the units with single fan, the fan motors have two speeds; : when in cooling mode, When in heating mode, For the units with two outdoor fan motors, in some occasions, one motor will stop: When in cooling mode, When in heating mode, 2

Overload of current Overload of current Check the current, normally Is the current in rated range? No Yes The outdoor PCB is defective Possible reason 1. Outdoor fan is defective 2. The compressor is defective 3. Refrigerant is over charged 4. Air enter the refrigerant system 5. Heat exchanger is too dirty c.
d. Protection of pressure or temp. Protection of pressure or temp. Yes Is it k1 or K2 open ? Is temp. protective switch K1 open Is pressure protective switch K2 open Yes Possible reason 1. The wires is loose to K1 2. Air or other gas in the refrigerant. 3. Heat exchanger is dirty 4. Outdoor fan or fan blade is defective 5. Outdoor unit is bad ventilation 6. Refrigerant is leakage 7. K1 switch is defective Yes Possible reason 1. The wires is loose to K2 2. Air or other gas in the refrigerant. 3.

No Yes Check the resistance of the temp. sensor according to Annex 1 Repair connector Is it the resistance is normal? No Yes Indoor PCB is defective. Replace the sensor g. High temperature protection of condenser High temperature protection of condenser Check the resistance of the temp. sensor according to Annex 1, is it normal? Yes Possible reason 1. Air or other gas in the refrigerant. 2.
9. Q&A (1) What is the value of evaporation temperature which is used for calculate cooling capacity? The evaporation temperature for all of indoor units is around 9-12°C, tested in standard cooling conditions.
Installation 1.Precaution on Installation .............................................. 132 2.Vacuum Dry and Leakage Checking.............................. 133 3.Additional Refrigerant Charge ....................................... 135 4.Water Drainage ............................................................. 136 5.Insulation Work ............................................................. 139 6.Wiring ........................................................................... 140 7.Test Operation .
1. Precaution on Installation 1). Measure the necessary length of the connecting pipe, and make it by the following way. a. Connect the indoor unit at first, then the outdoor unit. Bend the tubing in proper way. Do not harm them. Specially Notice the pipe length/height/dimension of each capacity.
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. Special vacuum dry procedure l This vacuum dry method is used in the following conditions: l There’s moisture when flushing the refrigerant pipe. l Rainwater may enter into the pipe. l 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.
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.
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 1.5~2m 4.1.3.
For Four-way cassette 4.4 Convergent drainage 4.4.1. The number of indoor units should be as small as possible to prevent the traverse main pipe overlong. 4.4.2. Indoor unit with drain pump and indoor unit without drain pump should be in different drainage system. 4.4.3. Selecting the diameter Number of connecting indoor units→Calculate drainage volume→Select the diameter Calculate allowed volume =Total cooling capacity of indoor units(HP)×2 (l/ hr) Allowed volume(lean 1/50) (l/ hr) I.D.
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. l Keep on pouring water until it gives an alarm signal for high water level, check if the pump drains water at once.
5. Insulation Work 5.1 Insulation material and thickness 5.1.1. Insulation material Insulation material should adopt the material which is able to endure the pipe’s temperature: no less than 70℃ in the high-pressure side, no less than 120℃ in the low-pressure side(For the cooling type machine, no requirements at the low-pressure side.) u Example: Heat pump type----Heat-resistant Polyethylene foam (withstand above 120℃) Cooling only type----Polyethylene foam (withstand above 100℃) 5.1.2.
For construction convenience, before laying pipes, use insulation material to insulate the pipes to be deal with, at the same time, at two ends of the pipe, remain some length not to be insulated, in order to be welded and check the leakage after laying the pipes. 5.2.3.
7. Test Operation (1) The test operation must be carried out after the entire installation has been completed. (2) Please confirm the following points before the test operation. l The indoor unit and outdoor unit are installed properly. l Tubing and wiring are correctly completed. l The refrigerant pipe system is leakage-checked. l The drainage is unimpeded. l The ground wiring is connected correctly. l The length of the tubing and the added stow capacity of the refrigerant have been recorded.
