Please tie the pipe and power line together with vinyl tape as shown in the figure showing the installation of Indoor and Outdoor units. Then fix their position with holders. To enchance the heat insulation and to prevent water condensation, please cover the outdoor part of the drain hose and pipe with insulation pipe. Completely seal any gap with putty. 2 Installation Of Remote Controller 3 Power Source And Operation Test The remote controller can be placed in its holder which is fixed on wall or beam. To operate the remote controller at its holder, please ensure that the unit can receive signal transmitted from the controller at the place where the holder is to be fixed. The unit will beep when signal is received from the remote controller. The signal transmission is weaken by the fluorescent light. Therefore, during the installation of the remote control holder, please switch on the light, even during day time, to determine the mounting location of the holder. Power Source ! CAUTION Please use a new socket. Accident may occur due to the use of old socket because of poor contact. Please plug in and then remove the plug for 2 – 3 times. This is to ensure that the plug is completely plugged into the socket. Keep additional length for the power cord and do not render the plug under external force as this may cause poor contact. Do not fix the power cord with U-shape nail. Operation Test Please ensure that the air conditioner is in normal operating condition during the operation test. Explain to your customer the proper operation procedures as described in the user’s manual. The controller must be hooked onto the hook at the lower part of the holder. Push in the remote controller in the direction as shown in figure below. 3 Procedures of using Vacuum Pump for Air Removal As shown in right figure, remove the cap of valve core. Then, connect the charge hose. Remove the cap of valve head. Connect the vacuum pump adapter to the vacuum pump and connect the charge hose to the adapter. Fully tighten the “Hi” shuttle of the manifold valve and completely unscrew the “Lo” shuttle. Run the vacuum pump for about 10–15 minutes, then completely tighten the “Lo” shuttle and switch off the vacuum pump. 2 Completely unscrew the spindle of the service valve (at 2 places) in anticlockwise direction to allow the flow of coolant (using Hexagonal Wrench key). 3 Remove the charge hose and tighten the cap of valve head. Check the cap’s periphery if there is any gas leakage. The task is then completed. 4 1 1 Preparation of Pipe Use a pipe cutter to cut the copper pipe. Jagged edge will cause leakage. Point the side to be trimmed downwards during trimming to prevent copper chips from entering the pipe. Before flaring, please put on the flare nut. 2 Pipe Connection INSTALLATION OF REFRIGERATING PIPES AND AIR REMOVAL ! CAUTION AIR REMOVAL WARNING If you cannot attach the side cover due to the connecting cord, press the connecting cord in direction to the front panel to fix it. Be sure that the hooks of the side cover is fixed in certainly. Otherwise water leakage may occur and this causes short circuit or faults. The connecting cord should not touch to service valve and pipes. (It becomes high temperature in heating operation.) The naked part of the wire core should be 10 mm and fix it to the terminal tightly. Then try to pull the individual wire to check if the contact is tight. Improper insertion may burn the terminal. Be sure to use only power cables approved from the authorities in your country. For example in Germany: Cable type: NYM 3x1.5mm2. Please refer to the installation manual for wire connection to the terminals of the units. The cabling must meet the standards of electrical installation. There is an AC voltage drop between the L and N terminals if power is on. Therefore, before servicing, be sure to remove the plug from the AC outlet or switch off the main switch. Checking for the electric source and the voltage range Before installation, the power source must be checked and necessary wiring work must be completed. To make the wiring capacity proper, use the wire gauges list below for the lead-in from a pole transformer and for the wiring from a switch board of fuse box to the main switch and outdoor unit in consideration of the locked rotor current. Investigate the power supply capacity and other electrical conditions at the installation location. Depending on the model of room air conditioner to be installed, request the customer to make arrangements for the necessary electrical work etc. The electrical work includes the wiring work up the outdoor. In localities where electrical conditions are poor, use of a voltage regulation is recommended. IMPORTANT Cable length up to 16m up to 15m up to 25m Wire cross-section 1.6mm2 2.5mm2 4.0mm2 IMPORTANT THIS APPLIANCE MUST BE EARTHED. Procedures of Wiring Wiring of The Outdoor Unit Please remove the side cover for wire connection. ! ! WARNING CO...
