    Application Information ACK-E-2009 Water Pump The water pump will on if compressor is on during cooling cycle. The pump will remain on for at least 5 minutes after the compressor is off. During mode change from cooling to non-cooling mode, the pump will on for minimum 5 minutes. During defrost cycle, the pump will on and will on for another 5 minutes once the defrost cycle is terminated.

    ACK-E-2009 Application Information Installation Guideline Caution • Sharp edges and coil surfaces are potential injury hazard. Avoid from contact with them. (1) Installation Of Indoor Unit Preliminary Site Survey • Electrical supply and installation is to confi rm to local authority’s (e.g. National Electrical Board) codes and regulations.

  • Page 26 ACK-E-2009 Application Information (2) Installation Of Outdoor Unit As condensing temperature rises, evaporating temperature rises and cooling capacity drops. In order to achieve maximum cooling capacity, the location selected for outdoor unit should fulfi ll the following requirements: • Install the condensing (outdoor) unit in a way such that hot air distributed by the outdoor condensing unit cannot be drawn in again (as in the case of short circuit of hot discharge air).
  • Page 27 Application Information ACK-E-2009 (3) Refrigerant Piping Maximum Piping Length and Maximum Number of Bends When the pipe length becomes too long, both the capacity and reliability drop. As the number of bends increases, system piping resistance to the refrigerant fl ow increases, thus lowering the cooling capacity, and as the result the compressor may become defective.

  • Page 29 Application Information ACK-E-2009 (5) Vacuuming and Charging The pre-charged outdoor unit does not need any vacuuming or charging. However once it is connected, the connecting pipe line and the indoor unit need to be vacuumed before releasing the R22/R407C/R410A from the outdoor unit.
  • Page 30 ACK-E-2009 Application Information (6) Additional Charge • The refrigerant charge has already charged into the outdoor unit. For the piping length of 7.6m, additional refrigerant charge after vacuuming is not necessary. • When the piping length is more than 7.6m, please use the table below (unit in gram). Model 20C/CR 38 / 53...
  • Page 31 Application Information ACK-E-2009 The additional refrigerant charge amount recommended is a guideline for longer piping application.

  • Page 32 ACK-E-2009 Application Information Special Precautions When Dealing With Refrigerant R410A Unit (1) What is New Refrigerant R410A? R410A is a new HFC refrigerant which does not damage the ozone layer. The working pressure of this new refrigerant is 1.6 times higher than conventional refrigerant (R22), thus proper installation / servicing is essential.
  • Page 33 Application Information ACK-E-2009 (d) When charging R410A, ensure that only liquid is being withdrawn from the cylinder or can. This is to ensure that only the original composition of R410A is being delivered into the system. The liquid composition can be different from the vapor composition. Invert cylinder Dip-pipe without dip-pipe...
  • Page 34 ACK-E-2009 Application Information (7) Overall Checking • Ensure the following, in particular: 1. The unit is mounted solidly and rigid in position. 2.
