Both the suction and discharge lines transmit vibration from the compressor to the other cooling system components and the building. This vibration can cause unwanted noise and deterioration of tubing, leading to leaks of refrigerant and capillary tube control fluids.

The vibration absorber consists of a special flexible metallic hose with an overbraid. The end connections may be of solder connections, flanges or threaded male ends. Refrigerant travelling too quickly along with convolouted inner diameter of the absorber may cause whistling.

Vibration absorbers eliminate the need of looping copper tubing to avoid vibration. Vibration absorbers are not designed for compression or extention, so they must be oriented parallel to the crankshaft, not at right angles to it. If the absorber is mounted improperly, it will resist the rocking of the compressor instead of flexing along with it. For maximum control of vibration, two absorbers should be placed in each line, one forhorizontal movement and the other for vertical movement. Do not stress, compress or twist the absorbers during installation.

Install the unit as close to the compressor as possible, and at right angle to motion, as shown in Fig.1.

Anchor the refrigerant piping, as shown above, at the end of the unit furthest from the vibration source. Also, install the unit horizontally, as shown in Fig. 1, wherever possible. Allow sufficient space for the unit so that it will not be subject to static compression or tension after brazing it into place. Units should be installed in a straight line; they are not intended to compensate for offset piping.

If the unit is installed in an area where condensate can accumulate on it, cover the unit with a waterproof barrier (such as heat shrinkable PVC tubing or rubber tape) to prevent moisture from freezing under the braid and ferrules, causing the unit to rupture.
