4. Water Drainage

4.1 Gradient and Supporting

4.1.1 Keep the drainpipe sloping downwards at a gradient of at least 1/100. Keep the drainpipe as short as

possible and eliminate the air bubble.

4.1.2 The horizontal drainpipe should be short. When the pipe is too long, a prop stand must be installed to

keep the gradient of 1/100 and prevent bending. Refer to the following table for the specification of the prop

stand.

Diameter Distance between the prop stands

Hard PVC pipe 25~40mm 1.5~2m

4.1.3. Precautions

The diameter of drainpipe should meet the drainage requirement at least.①

The drainpipe should be heat② -insulated to prevent atomization.

Drainpipe should be installed before installing indoor unit. Aft③ er powering on, there is some water in

water-receiver plate. Please check if the drain pump can operate correctly.

All connection should be firm.④

Wipe color on PVC pipe to note connection. ⑤

Climbing, horizontal and bending conditions are prohibited.⑥

The dimension of drainpipe can’t less than the connecting dimension of indoor drainpipe.⑦

Heat⑧ -insulation should be done well to prevent condensation.

Indoor units with different drainage type can’t share one convergent drainpipe.⑨

4.2 Drainpipe Trap

4.2.1. If the pressure at the connection of the drainpipe is negative, it needs to design drainpipe trap.

4.2.2. Every indoor unit needs one drainpipe trap.

4.2.3. A plug should be designed to do cleaning.
