Install drain hose
• The diameter of the drain hose should be equal or bigger than the connection pipe’s. ( The
diameter of polythene pipe: Outer diameter 25mm surface thickness .5mm)
• Drain hose should be short and falling gradient should more than /00 to prevent the
formation of air bubble.
• If drain hose cannot has enough falling gradient, drain raising pipe should be added.
• To prevent bent of the drain hose, the distance between hoisting stand should is m to .5m.
• Use the drain hose and clamp with the provided
attachment. Insert the drain hose to the drain
vent, and then tighten the clamp.
• Wrap the big sponge on the clamp of drain hose
to insulate heat.
• Heat insulation should be done to indoor drain
hose.
Note of drain raising pipe
• The install height of the drain raising pipe should less than 280mm.
• The drain raising pipe should form a upright angle with the unit, and distance to unit should not
beyond 300mm.
• The slant gradient of the attached drain hose
should be within 75mm so that the drain faucet
doesn’t has to endure the unnecessary outside
force.
• Install the drain hose according to the following process if several drain hoses join together.
• Check the smoothness of drain after installation.
• Check the drain by pouring 600cc water slowly into the outlet vent or test hole.
• Check the drain in cooling operation after installation of the electric circuit.
