  • Page 11: Installation Guideline

    Application Information Installation Guideline INDOOR PRELIMINARY SITE SURVEY a) Electrical supply and installation is to conform 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. c) Ensure that the location is convenient for wiring and piping. MOUNTING a) For ceiling mounted models, locate a position where piping and ducting work can be kept to a minimum.
  • Page 12 Application Information INDOOR CLEARANCE Mounting Ensure that the overhead supports are strong enough to hold the unit’s weight. Position hanger rods and check for alignment with the unit. Check that hangers are secure and that the base of fan-coil unit is level in the two horizontal directions, taking into account the gradient recommended for drainage flow as shown.
  • Page 13 Application Information 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:- a) 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). Allow sufficient space for maintenance around the unit.
