Drain pipe and Drain Hose Installation
Care must be taken when installing the drainpipe and drain hose for the indoor unit so that condensate water is
drained correctly outside.
1. Fix the flexible hose to the drainpipe.

• The connection port of the flexible hose and PVC drainpipe must be
fixed with PVC adhesives.
• Check out that the connected part doesn't leak.
• Drain pipe type : VP20(AM✴✴✴FN1DCH✴),
VP25(AM✴✴✴FN2DCH✴)

• Push the supplied drain hose as far as possible over the drain
socket.
• Tighten the metal clamp as shown in the picture.
• Wrap the supplied large sealing pad over the metal clamp and
drain hose to insulate and fix it with clamps.
• Insulate the complete drain piping inside the building (field
supply).
If the drain hose cannot be sufficiently set on a slope, fit the hose
with drain raising piping (field supply).
• Push the drain hose up to insulation when connecting the drain
hose to drain socket.
2. Connect the flexible hose to the drain hose port.
• Make sure that a rubber ring is installed on the drain hose port.
• Drain hose port location differs depending on the unit types.
3. Install the drain pipe as shortly as possible.
• Give a slightly slant to the drainpipe for proper drainage of condensate
water.
• There must be no gap on the connected part so that the drainpipe is
not separated from the flexible hose.
4. Insulate the drainpipe, and then fix it as indicated.
• Whole drainpipe should be insulated by 5t(or more) insulation to
prevent water condensation.
