320DV SERIES ISOLATION FLOAT VENT VALVES

INSTALLATION AND MAINTENANCE INSTRUCTION

Please read these warnings and use the assembly instructions completely and carefully before starting.

Failure to do so may cause product failure, or result in environmental contamination due to liquid leak-

age into the soil, creating hazardous spill conditions.

Check to make sure the unit is intact and undamaged and all parts have been supplied. Never substitute

parts for those supplied. Doing so may cause product failure and void warranty.

Using electrically operated equipment near gasoline or gasoline vapors may result in a fire or explosion, causing personal

injury and property damage. Be sure that the working area is free from such hazards, and always use proper precautions.

At all times when product is in the storage tank keep the riser pipe capped, so the vapors cannot escape into the environment.

1. FIELD INSTALLATION INSTRUCTIONS

OPW Overfill Warning Systems should only be used on submerged pumping systems,

and not with suction pump systems. OPW Overfill Warning Systems should only be used

on gravity drop systems. DO NOT use where Pump Off Unloading is used.

Valve must be mounted vertically with the two threads at the top of the valve. Ball float will

only operate properly if installed vertically.

1. Apply a non-hardening, gasoline resistant pipe compound on the two threads. Tighten down to

pipes or plug.

Do not use plastic or teflon tape!

2. Attach bottom of fitting to 2” pipe (50 mm) using supplied gasket and nut.

3. Make sure ball float moves freely, full stroke, without binding.

2. PREVENTIVE MAINTENANCE

Every three years, remove and inspect the valve for damage, contamination, corrosion, and free-

dom of movement of the ball float. Replace if damaged or corroded.
