11. INSTALLATION 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 confirm to local authority's (e.g. National Electrical Board) codes and regulations.
Please ensure that the following steps are taken: Check the gradient for drainage flow as recommended in Figure B. Provide clearance for easy servicing and optimal air flow as shown in Figure C. The indoor unit must be installed such that there is no short circuit of the cool discharge air with the warm return air.
Page 48
Under Ceiling Installation Install the Suspension Bolts Install the suspension bolts so that it can support the indoor unit. Adjust the distance to ceiling before installation. Refer to the dimension given (Figure A) to install the unit. Install the Indoor Unit Insert the suspension bolts into the fittings of the hanger bracket.
Floor standing installation 1. Refer to the dimension as illustrated when installing the mounting bracket. 2. Determine the pipe hose position using the rear piping hole. Drill the pipe hole at the slight downward slant to the outdoor side.

(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 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 54
(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 flow increases, thus lowering the cooling capacity, and as the result the compressor may become defective.
Page 55
(4) WIRING ELECTRICAL CONNECTIONS Wiring regulations on wire diameters differ from country to country. Please refer to your LOCAL ELECTRI- CAL CODES for field wiring rules. Be sure that installations comply with the rules and regulations. GENERAL PRECAUTIONS Ensure that the rated voltage of the unit corresponds to the name plate before carrying out proper wiring according to the wiring diagram.
Page 56
Diagram shows typical charging method: Note : R407C – Fix filter dryer R22 - Nil R410A - Nil (7) OVERALL CHECKING Ensure the following, in particular: The unit is mounted solidly and rigid in position. Piping and connections are leak proof after charging. Proper wiring has been done.
Page 57
(9) SPECIAL PRECAUTIONS WHEN DEALING WITH REFRIGERANT R410A UNIT 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 58
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...

13. 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.
Diagnostic Guidelines By means of pressure reading: Pressure Data Probable cause Circuit 1. Overcharged with refrigerant. High side Low side 2. Non-condensable gases in refrigerant circuit (e.g. air) 3. Obstructed air-intake / discharge. 4. Hot air short circuiting in outdoor unit. High side 1.
Page 63
By means of diagnostic flow chart: Generally, there are two kinds of problems, i.e. starting failure and insufficient cooling/heating. “Starting failure” is caused by electrical defect while improper application or defects in refrigerant circuit causes “Insufficient cooling / heating”. i) Diagnosis of Electric Circuit The most common causes of air conditioner failure to “start”...
Page 64
ii ) Diagnosis of Refrigerant Circuit / Application There might be some causes where the unit starts running but does not perform satisfactorily, i.e. insufficient cooling. Judgement could be made by measuring temperature difference of indoor unit’s intake and discharge air as well as running current.
