Installation
Note:
After gas pipe and liquid pipe are carried out heat insulation separately, bind with tape. If it is
bound over tightly, the spliced insulation joint shall be damaged.
b. The surrounding of pipe connecting section shall be carried out insulation entirely.
Highlights:
1. No gap in joint of insulation materials.
2. If the joint of insulation materials is linked tardily and tape is bound over tightly, shrinkage and leakage
shall be produced easily to create phenomena of dew-drop. The over-tightened tape shall edge out air in
material, leading to decrease the insulation effect at this part; meanwhile tape shall be easily aged and
drop down.
3. In indoor shield space, it is no necessary to bind belting, so as to avoid influencing insulation effect.
Correct repairing method for insulation cotton: (see the figure below)
Firstly cut out the material longer than gap, expend the two ends and embed the insulated cotton, at last,
paste joint with glue.
Highlights of insulation repairing:
1. Repaired length of insulation (insulation tube with filled gap) shall be
1-31/32in.~3-15/16in.(50~100mm) longer than the length of gap under natural status.
2. Sliver the cut of insulation to be repaired and cross-section shall be even.
3. Insert gap with insulation for repairing and cross-section shall be pressed tightly.
4. All cross-section and cut need to be pasted with glue.
5. Finally, bind the seam with rubber/plastic tape.
6. Prohibit conducting insulation by using binder fabric in concealed section, so as to avoid influencing
insulation effect.
6.2 Insulation of Condensate Water Pipe
6.2.1 Insulation of condensate water pipe
1. Select rubber/plastic tube with burning retardant of rating B1.
2. Thickness of insulation layer is usually above 15/24in.(10mm).
3. The insulation material at water outlet of unit body should be pasted with glue on the unit body, so as
to avoid dewing and dripping.
4. Pipe installed in wall shall not be conduct insulation.
5. Use specific glue to paste the seam of insulation material, and then bind with cloth tape. The width of
tape shall not be less than 1-31/32(50mm). Make sure it is firm and avoid dewing.
