● Height Adjustment
e) Make an adjustment so that the unit proper may be located at a correct position. After the adjustment, remove the level gauges.
f) Check the unit proper for installation height and leveing.
● Since a condensate pump and a float switch are contained indoor unit body, be sure not to incline the unit body.
Note: If the unit is installed with a gradient in reverse direction of the drain piping side, a malfunction
will be caused to the fioat switch, leading to water leakage.
● Check the levelness at foue cormers by using a vinyl tube filled with water.
(d) Drain piping
1) Drain piping should always be in a downhill grade (1/50-1/100) and avoid riding across an elevation or making traps.
● Good piping ● Improper piping
2) When connecting the drain pipe to the unit, pay suffcient attention not to apply excess force to the piping on the unit side. Also,
fix the piping at a point as close as possible to the unit.
3) For drain pipe, use hard PVC ganeral purpose pipe VP-25 (I.D.1'') which can
be purchased locally. When connecting, insert a PVC pipe end securely into
the drain socket before tightening securly using the attached drain hose and
clamp. Adhesive must not be used connection of the drain socket and drain
hose (accessory).
