for any damage. If damage exists
return product for replacement.

3. Replace and tighten plastic cap on air fitting.
Installation
1. The Diatrol should be installed as close to the offending fixture
or source of water hammer as possible.
2. Once the Diatrol is installed, check the CWS line for any
leakage. Make repairs if necessary.
Maintenance

including the Diatrol, yearly and more frequently as the system
ages.
Operation
1. The Diatrol is installed in the line as close to the offending fixture
as possible. Its sealed-in air pre-charge prevents water from
entering it until the system pressure exceeds the pre-charge
pressure. A properly pressurized tank will only allow a small
volume to enter its bladder under normal flow conditions.
2. When a sudden valve closure occurs, the resulting pressure
surge travels back from the valve to the bladder-type shock
suppressor forcing the bladder to expand into the air cushion.
3. The shock is absorbed by the compressing of the air. After
absorption of the shock, the system water pressure and the air
chamber pressure equalize at the static pressure level.
4. Water temperature is not to exceed 240°F or fall below 35°F.
