When connecting the water pipe, apply lubricant such as soap water around the water
pipe adapter.
Before wrapping the water pipe with thermal insulation foam, hold one end of the
insulation foam and pour a small amount of soap water to the insulation foam. Hold the
other end of the insulation foam, and shake the insulation foam back and forth to dump
unnecessary soap water. Then wrap the water pipe with the insulation foam.
When wrapping the water pipe with thermal insulation foam, apply glue to the surface of
joints evenly. After the water pipe is wrapped with insulation foam, press the joints at
both sides with your thumb to ensure that the joints are securely connected. Apply glue
to the two ends of the insulation foam to seal the pipe. The glue width at the two ends
must be greater than the thickness of the insulation foam.
