Note 4
：
As the pipeline is susceptible to stress deformation after welding which will lead to
the incapability connection of compressor after dismantling. Thus, connection of
the evaporator and condenser pipe outlet should be equipped with a pair of locking
flange in order to increase the assembling clearance. These two flanges on
evaporator and condenser need to be released during the connection of the
compressor so as to reduce the effect of welding pipe deformation.
Caution
：
Sometimes in order to prevent leakage at the connections of compressor, the
overtightening of flange bolts can happen. This could cause the suspension of the
compressor in the air, leading to excessive vibration and damage of the
compressor. Thus, please follow the instructions on compressor mounting (refer
to 6.2 Installation and fixation of the compressor) and the advice of using flange
connections.
