Installation procedure
Install indoor unit
(d)When the equipped drain hose used to many units, the positi- on of public pipe should be 100mm lower than the drain hole of any unit. As the figure shown. For this purpose, the thicker pipe should be used.
Guarantee the most possible high fall (about 100mm)
Indoor unit | Indoor unit |
1/100 slant degree or more
(e) The stiff PVC pipe put indoor side should be heat insulated.
(f ) The lifting height of the drain hose should be at the position over ceiling within 500mm. When there is obstacle on the ceiling , use bracket and things alike to lift the drain hose to avoid the obstacle. During this work, if the extending height is higher than 500mm, the return flow of drainage may become too much leading to the drainage groove overflow. So, the height of the drain hose should be kept within the tolerance range given in the follow figure.

(g)Avoid putting the outlet of drain hose in the places with irritant gas generated. Do not insert the drain hose directly into drainage, where the gas with sulfur may be generated.
Test of drainage system
(a)After finishing electric engineering, perform drainage system test.
(b)During test, confirm if the water properly passes through the pipe and there is no water leakage in the joint.
(c)In a new house, perform test before installing the ceiling.
(d)Even if installing the air conditioner in a heating operation needed season, the test also must be performed.*
Procedure
(a)Dismantle the side panel, slowly charge 1000cc water into the drain pan to confirm the smooth drainage and without water leakage.
(b)In Cooling operation, check the drainage system.
