[. . . ] (Use polyethylene foam as insulating material. ) Rear right 4 mm How to fix the drains cap 1) Insert hexagonal wrench (4 mm) in a center head. Left Bottom right Right Die-cutting Front panel slit Bottom left Changing drain hose Rear left Piping preparation Fig. 8-4-15 2) Firmly insert drains cap. No gap Do not apply lubricating oil (refrigerant machine oil) when inserting the drain cap. Die-cutting Front panel slit For leftward connection, cut out slit on the left side of the front panel. Changing drain hose For leftward connection, bottom leftward connection and rear leftward connection's piping, it is necessary to change the drain hose and drain cap. How to remove the drains cap Clip drain cap by needle-nose plier, and pull out. Fig. 8-4-16 CAUTION Firmly insert the drain hose and drain cap; otherwise, water may leak. <In case of right or left piping> · After scribing slits of the front panel with a knife or a making-off pin, cut them with a pair of nippers or an equivalent tool. Fig. 8-4-13 How to install the drain hose Firmly insert drain hose connecting part until hitting on a heat insulator. Slit Fig. 8-4-17 <In case of bottom right or bottom left piping> Heat insulator · After scribing slits of the front panel with a knife or a making-off pin, cut them with a pair of nippers or an equivalent tool. Drain hose Fig. Indoor unit fixing Bend the connecting pipe so that it is laid within 43 mm 1. Pass the pipe through the hole in the wall, and hook above the wall surface. Install the outdoor unit without anything blocking the air discharging. When the outdoor unit is installed in a place exposed always exposed to strong wind like a coast or on a high storey of a building, secure the normal fan operation using a duct or a wind shield. In particularly windy areas, install the unit such as to avoid admission of wind. · A place where high-frequency waves are likely to be generated as from audio equipment, welders, and medical equipment. Drain hose Inside the room Extension drain hose Fig. 8-4-23 CAUTION Arrange the drain pipe for proper drainage from the unit. This air conditioner has the structure designed to drain water collected from dew, which forms on the back of the indoor unit, to the drain pan. Therefore, do not store the power cord and other parts at a height above the drain guide. Wall Drain guide Strong wind Space for pipes Fig. Cut the pipe with a pipe cutter. Obliquity Roughness Warp (Unit : N·m) Outer dia. of copper pipe 6. 35 mm 9. 52 mm Tightening torque 16 to 18 (1. 6 to 1. 8 kgf·m) 33 to 42 (3. 3 to 4. 2 kgf·m) 90° Fig. · Projection margin in flaring : A (Unit : mm) A · Tightening torque of flare pipe connections The operating pressure of R-410A is higher than that of R-22. It is therefore necessary to firmly tighten the flare pipe connecting sections (which connect the indoor and outdoor units) up to the specified tightening torque.
