    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 91: 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 92 b) Ensure that there is no obstruction of air flow into or out of the unit. Remove obstacle which block air intake or discharge. c) The location must be well ventilated, so that the unit can draw and distribute plenty of air thus lowering the condensing temperature.
  • Page 93 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 94 Installation Clearance A) For MMC – B/BR series (Single/Multiple Condensing Unit) When two or more outdoor units are installed in a location, they must be positioned such that one unit will not be taking the hot discharge air from another. This also applies when two or more units are installed one above the other.

    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.

  • Page 99: Operation

    Operation Electrical Connection Wiring regulations about wire diameter differs from country to country. Please refer to your LOCAL ELECTRICAL CODES for field wiring rules. Be sure that installation comply with such rules and regulations. General Precaution Ensure that the rated voltage of the unit correspond to the name plate before carrying out proper wiring according to the wiring diagram.
