10 English
• To keep the drain hose from sagging, space hanging wiring
every 1 to 1.5m. (Refer to Fig. 26)
• Use only the included drain hose (1), (for rightward running
drain hose) or elbow (10) (for upward running drain hose)
and clamp (2).
• Fit the drain hose (1) or elbow (10) over the drain piping up
to the neck and fasten tight with the metal clamp (2).
• Tighten the metal clamp (2) unit the screw head is less than
4mm from the hose.
• Insulate the metal clamp (2) and drain hose or elbow (10)
with the included sealing pad (8). (Refer to Fig. 28)
• Make sure that heat insulation work is executed on the fol-
lowing 2 spots to prevent any possible water leakage due to
dew condensation.
• Insulate the drain hose inside the building
• Drain socket
CAUTION
• Do not twist or bend the drain hose (1), so that excessive
force is not applied to it, as this could cause leaks.
• If converging multiple drain piping, install according to the
procedure shown below. (Refer to Fig. 29)
Select converging drain piping whose gauge is suitable for
the operating capacity of the unit.
PRECAUTIONS FOR UPWARD DRAIN RAISING PIPING
• Install the drain raising piping at a height of less than
500mm.
• Install the drain raising piping at a right angle to the indoor
unit. (Refer to Fig. 30)
CAUTION
If the upward running drain hose leans at a slant, the float
switch will malfunction and water will leak.
7-2 After piping work is finished, check if drainage
flows smoothly.
• Open the water inlet lid, add approximately 1 liter of water
slowly and check drainage flow. (Refer to Fig. 31)
