• EMCO Drill Fixture p/n 566675
CAUTION:
1. Always barricade to keep pedestrians and vehicles from accessing the
storage tank area during preventive maintenance and/ or compliance testing
of the EMCO phase I EVR system.
2. If the underground storage tank is equipped with a ball float vent valve, make
sure it does not extend below the positive shut-off point of the A1100EVR
overfill prevention valve. If so, the ball float valve must be removed to allow
proper operation of the A1100EVR overfill prevention valve.
3. Never disconnect the delivery elbow from the fill adapter when the
A1100EVR overfill prevention valve has reached the positive shut-off point of
95% total capacity. Note the tank delivery hose is full and must not be dis-
connected until enough fuel has been evacuated from the underground stor-
age tank. This will allow the tank delivery hose to drain, and to safely discon-
nect from the fill adapter. Premature disconnection will result in a hazardous
spill and/or a potential for personal injury and property damage.
4. Once the A1100EVR overfill prevention valve is completely assembled, the
Seals-All Sealant must cure for a minimum of 24 hours before installing
into the underground storage tank.
