  • Page 105: Installation (Indoor)

    Installation (Indoor) PRELIMINARY SITE SURVEY a) Electrical supply and installation is to confirm to local authority’s (e.g. National Electricity Board) codes and regulations. b) Voltage supply fluctuation must not exceed +/- 10% of rated voltage. Electricity supply line must be independent of welding transformers which can cause supply fluctuation.

  • Page 106: Installation (Outdoor)

    Installation (Outdoor) LOCATION FOR INSTALLATION OF THE CONDENSING UNITS As condensing temperature rises, evaporating temperature rises and cooling capacity drops. In order to achieve maximum cooling capacity, the location selected should fulfill 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 107: Field Piping

    FIELD PIPING To ensure satisfactory operation and performance, the following points should be noted for the field piping arrangements of the complete refrigerant cycle. a) Liquid loops or oil traps must be provided according to the position of the outdoor and the indoor units (depending on whether the indoor unit is above or below the outdoor unit).

  • Page 108: Vacuuming And Charging

    SERVICE PANEL INSTALLATION CLEARANCE VACUUMING AND CHARGING Vacuuming is necessary to eliminate all moisture and air from the system. AMC-D/DR Condensing Unit is equipped with shredder valve and charging nipples for this purpose. VACUUMING After the system pipings are properly connected, connect the flexible hoses to the correct charging nipples as shown in the diagrams.
  • Page 109 GUIDELINES OF FIELD-CHARGING AIR CONDITIONING SYSTEMS WITH SCROLL COMPRESSORS These guidelines are intended for use with Scroll compressors only with R22, R407C, R134a, R404A, R507, and R410A refrigerants. They do not apply to reciprocating compressors or competitive Scroll compressors. FIELD-CHARGING – SOME PRECAUTION POINTS Scroll compressors have a very high volumetric efficiency and quickly pump a deep vacuum if there is insufficient refrigerant in the system or if refrigerant is added too slowly.

    Special Precautions For R407c Special Precautions When Dealing With Refrigerant R407C Unit 1) What Is New Refrigerant R407C? R407C is a zeotropic refrigerant mixture which has Zero Ozone Depletion Potential (ODP = 0) and thus conformed to the Montreal Protocol regulation. It requires Polyol-ester oil (POE) oil for its compressor's lubricant. Its refrigerant capacity and performance are about the same as the refrigerant R22.
  • Page 114 c) Ensure that the compressor is not expose to open air for more than the recommended time specified by its manufacturer (typically less than 10 minutes). Removed the seal-plugs only when the compressor is about to be brazed. d) The system should be thoroughly vacuumed to 1.0 Pa (-700mmHg) or lower. This vacuuming level is more stringent than R22 system so as to ensure no incompressible gas and moisture in the system.

  • Page 115: Servicing And Maintenance

    Servicing And Maintenance The design concept of the Condensing Unit is such that all servicing can be done from the front and side of the unit. Upon removal of front and side panel, all the electrical "terminal box", fan and motor assembly and compressor are easily accessible.
