Explanation to the users.

Remarks

Separate the touching pipes, if any.

Apply cushion material between Comp. base and Tray drip.

Move or change the points of vibration absorber rubbers on the pipes to reduce the shaking.

Attach a absorber on the comp. head.

●Refrigerant is erupting rapidly from the compressor to circulate pipes, so pipe shaking noise can make to some degree.

●In case compressor vibration is sent to a pipe directly, apply vibration absorber rubbers to welding points of the pipe and comp. or to a much bent point on the pipe.
