RH95 is extremely noisy
If the RH95 makes a very loud noise when in operation, it is possible that the transit screws have not been removed from the transit position.
The RH95 is shipped with 2 screws in the base of the unit to hold the vacuum pump in place during shipping to prevent damage to the unit. If these screws are not removed before use, the pump effectively has no vibration damping and the system will be extremely noisy. Remove the two screws from the base of the unit and store them in the provided holes on the back panel of the RH95, as shown below:
Make sure to replace the transit screws in the base of the unit before shipping the RH95
