[. . . ] Ask the dealer or authorized company to install the units except room air conditioners for the U. S. A and Canada area. If the unit is installed improperly, water leakage, electric shock or fire may result. Mount with the lowest moving parts at least 2. 5 m above the floor or grade level. (If applicable) The manufacturer does not assume responsibility for accidents or injury caused by an incorrectly installed air conditioner. [. . . ] This device must be installed according to the national electrical rules. Max input power & current is measured according to IEC standard and input power & current is measured according to ISO standard. E-4 PREPARING THE INSTALLATION Respect the clearances and maximum lengths indicated in the diagram below when installing the unit. 300 mm or more 300 mm or more Wrap the refrigerant pipes and the drain hose up in the absorbent pad and the vinyl tape, refer to page 13. This drain direction is selectable to left or right. 125 mm or more 7 metres maximum 600 mm minimum 15 metres maximum 300 mm minimum 300 mm minimum 600 mm minimum E-5 PREPARING THE INSTALLATION Air Conditioner and Accessories The following accessories are supplied with the air conditioner. The quantities are indicated in parentheses.

The drain plug and rubber leg are only included when the air conditioner is supplied w ithout the assembly piping illustrated below. E-6 INSTALLING THE UNIT Fixing the Installation Plate Before fixing the installation plate to a wall or window frame, you must determine the position of the 65 mm hole through which the cable, piping and hose pass to connect the indoor unit up to the outdoor unit. When facing the air conditioner in position on the wall, the piping and cable can be connected from the: Right Left Rear (right or left) Pipe hole (Ø65mm) Installation plate 30mm 90 1 Determine the position of the pipe and drain hose hole using the right figure and drill the hole with an inner diameter of 65 mm so that it slants slightly downwards. If you are fixing the indoor unit to a. . . Pass the drain hose under the refrigerant piping, taking care to keep the drain hose tight. Pass the drain hose through the hole in the wall, making sure that it is sloping downwards, as shown in the illustrations above. The hose will be fixed permanently into position once the whole installation has been tested for gas leaks; refer to page 13 for further details. Shield Drain hose Extension drain hose Installing and Connecting the Outdoor Unit Drain Hose When using the air conditioner in the heating mode, ice may accumulate. During de-icing, the condensed water must be drained off safely. Consequently, you must install a drain hose on the outdoor unit, following the instructions below . 1 Insert the drain plug into the drain hole on the underside of the outdoor unit. Drain hole 2 Connect the drain hose to the drain plug. 3 Ensure that the drained water runs off correctly and safely. E-9 INSTALLING THE UNIT Installing and Connecting the Indoor Unit Assembly Piping There are two refrigerant pipes of different diameters: A smaller one for the liquid refrigerant A larger one for the gas refrigerant A short length of piping is already fitted to the air conditioner. You must extend this piping using assembly piping (optionally supplied). The connection procedure for the refrigerant piping varies according to the exit position of the piping from the indoor unit, as seen when facing the air conditioner in position on the wall: B A Right (A) Left (B) Rear 1 With a knife, cut out the appropriate knock-out piece on the rear of the indoor unit (unless you are connecting directly from the rear). Smooth the cut edges. 2 3 Remove the protection caps on the pipes and connect the assembly piping to each pipe, tightening the nuts, first manually and then with a torque wrench, applying the following torque. Outer Diameter 6. 35 mm 9. 52 mm Torque (kgf·cm) 140 ~ 170 250 ~ 280 7 For further details on how to connect up to the outdoor unit and purge the circuit, refer to page 12. E-11 COMPLETING THE INSTALLATION Connecting Up and Purging the Circuit The outdoor unit is loaded with sufficient R22 refrigerant for 5 metres of piping. The air in the indoor unit and in the pipe must be purged. [. . . ] Mount the valve stem nuts and the service port cap to the valve, and tighten them at the torque of 183kgf·cm with a torque wrench. - At this time, especially check for gas leakage from the 3-way valve's stem nuts, and from the service port cap. 4 5 Vacuum Pump 6 * The designs and shape are subject to change according to the model. 7 Valve stem Stem cap A (gas) B (liquid) 8 Adding Refrigerant Refrigerant must be added if the piping measures more than 5 metres in length. This operation can only be performed by a qualified refrigeration specialist. More than 5 metres of piping Less than 5 metres of piping Then. . . [. . . ]
