Pre-Installation
1. Visually inspect the Diatrol
®
for any damage. If damage exists
return product for replacement.
2. Adjust pre-charge to equal 10% below system pressure.
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 leaks.
Make repairs if necessary.
Maintenance
1. A licensed professional should check the complete system,
including the Diatrol, yearly and more frequently as the
system ages.
Operation
1. The Diatrol should be 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.
