3.7 Leak detection and Heat insulation
Use soap water or a leak detector to check whether gas leakage exists at the adapers.
Density threshold: Density of the Freon gas that does not harm the human body. Density
threshold of R22: 0.3kg/m
In order to keep the refrigerant density below the threshold value, please install a mechanic
ventilation device. The leakage detection alarm device should be installed at the place
vulnerable to retention of the refrigerant.
In case frequent ventilation is impossible, please install the leakage detection alarm device
linked with the mechanical ventilation device.
Use heat resistant materials as heat insulation materials to wrap the part protrduing outside the
flared pipe joint and the refrigerant pipe of the liquid pipe and the gas pipe, and ensure that no
gap exists between them.
Cover heat insulation materials separately at the liquid side and gas side. Moreover, perform
heat insulation thoroughly for the gas side pipes of the indoor unit, and prevent water from
dripping outside the unit.
After applying the auxiliary heat insulation materials, use some tapes to seal it.
