(4) Suspend the header to the ceiling, and be sure to install the T-type manifold so that
the outlet pipes are horizontal at the lower side. See Fig. 4.4.7.
(5) Thermal insulation for pipeline
1) To avoid condensate or water leakage on connecting pipe, the gas pipe and liquid
pipe must be wrapped with thermal insulating material and adhesive pipe for
insulation from the air.
2) For heat pump unit, liquid pipe should bear 70ºC(158° F) or above, and gas pipe
should bear 120ºC(248° F) or above. For cooling only unit, both liquid pipe and gas
pipe should bear 70ºC(158° F) or above. Example: Polyethylene foam can bear 120
ºC(248° F) above and foaming polyethylene can bear 100ºC(212° F) above.
