Extend the drain pipe.
①
To extend the length of a drain pipe, you need to purchase an extension drain pipe locally. Make sure the
extension portion of the drain pipe indoors undergoes heat insulation treatment.
CAUTION
Indoor parts of the drainage pipe shall be insulated to prevent condensation, and protective sleeves should be thicker
than 10mm.
If the pipe is not wholly insulated, be sure to rebind the cut part.
Use glue or buckles to connect the joints and cuts of the thermal insulation pipe, and make sure it is at the top of the
pipe.
After the drainage test shows that there are no leaks, carry out the insulation of the drainage pipe.

Lay and insulate pipes.
①
Straighten and place the connecting pipes on the floor, and lay the
drainage pipe and various cables (remember to distinguish the two ends of
the cable) around the connecting pipes.
①
Measure and adjust the distances of the low-pressure pipe, high-pressure
pipe and various cables based on the mouth of the drainage pipe, and bind
them together with cable ties.
①
Sort the pipes and cables in the following sequence: drainage pipe at the
bottom, connecting pipe in the middle, and power cable at the top.
①
Start wrapping from the drainage pipe and tie a fast knot.
