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.

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.

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.

Service & Maintenance MAINTENANCE For superb performance and lasting durability, please do not forget to conduct proper and regular maintenance. Cleaning The Outdoor Unit Heat Exchanger If you use your air conditioner for prolonged period of time, the outdoor unit heat exchanger will become dirty impairing its function and reducing the performance of the air conditioned.
Troubleshooting Troubleshooting When a malfunction of the air conditioner unit is detected, immediately switch off the main power supply before proceeding with the following troubleshooting procedures. The following are common fault conditions and simple troubleshooting tips. If any other fault conditions which are not listed occur, contact your nearest local dealer.
Page 102
Troubleshooting Phase Sequencer The unit with Scroll Compressor can only rotate in one direction. For this reason, a protective device (phase protector) is fitted to prevent incorrect wiring of the electrical phases. When the three phases are not connected correctly, the phase protector operates, and the unit will not start. This device is located in the control box of the outdoor unit. The following table shows the LED indicator light for phase protector under normal operation and fault conditions.
