Discharge Bottle Support Adjustment

Properly adjust bottle supports in accordance with the start up checklist and the maintenance schedule. Ariel recommends using the following procedure:

1. With the system heat-soaked, shut down the compressor. Loosen the bottle supports and head

end supports (if applicable) so there is no contact between the bottle and support.

2. Place a magnetic base indicator as close as possible to the bottle support with the magnetic base

on a structurally stiff skid member. Place the indicator needle at the bottom center of the bottle.

Multiple supports on a single bottle require an indicator at each support.

3. Tighten the bottle supports only until there is a positive movement on the indicator: 0.003 to

0.005 inch.

4. Remove the indicators. Use a locking mechanism to prevent support bolting from loosening or

repositioning if the supports do not contact the bottle when the equipment cools.

5. Adjust head end cylinder supports (if applicable).
