◆ Install the drainpipe

When delivery, the outfall is PVC pipe, when connecting, please use the subsidiary of sealing materials and sleeve.

• Be sure to take the heat insulation of drainpipe of the indoor unit, if no heat insulation, it will have the condensate. The connecting part of indoor unit also needs heat insulation.
• Connecting the drainpipe, it should use the rigid PVC adhesive, and make sure there is no water leakage phenomenon.

Tilt down for above 1/100

●Note that it should not make the connector between the drainpipe and outfall of indoor unit to sustain any external force, include the weight of water pipe.

●The drainpipe to tilt down is above 1/100, it should be no bend in the middle.

●The lateral pull out of the drainpipe should be within 20 m. When the drain pipe is longer, please make the rack for support to prevent bending.

●The cut-connect interface of the drain system must be sealed to prevent water leakage.

●The end of drainpipe should have a distance of above 50 mm to the ground or the bottom drainage channels, and it should not put into the water. When the condensate is directly discharge to the stinking ditch, be sure to make a U-bend to form a water seal, in order to avoid stink getting into the room through the drain pipe.

- For the hanging installation construction, and drain pipes from many units are centralized constructed, it should provide a U-bend at the branch pipe of each unit, to prevent water refluxing from the main drain pipe.
