Testing the System
Testing the System
1. Carefully review all work completed, making sure that all mechanical joints are thoroughly tightened and that all
electrical connections are sealed.
2. Open the product crash valves and restore power to the dispenser.
3. With the power on, but no nozzles authorized, the VP1000-5 should not be running (unless the ambient
temperature is below 40°F), but the power LED (yellow) should be energized on the interface module.
4. Authorize one handle and the vacuum system should activate when the gasoline flow control valve is engaged.
Repeat for all other nozzles, individually testing each nozzle on each side of dispenser. With each authorization,
one of the green LED’s on the interface module should illuminate and the VP1000-5 activate.
Note:
For unihose dispensers, conduct individual tests for each product grade on each side of the dispenser to ensure
that the same LED activates for all grades on the same side. If the other LED activates, wiring needs to be
corrected.
5. Authorize one nozzle and listen to the speed of the VP1000-5. With only one nozzle activated, the speed will be
slower than if a nozzle on each side is activated. Activate a nozzle on the other side of the dispenser and listen for
the speed to change.
6. To test the tightness of the vapor plumbing installed on the suction side of the system requires a 0-100” water
column gauge. Connect the gauge into the 1/4” test port of the adaptor tee installed earlier (see Figures 6 and 7
for reference on test port installation and location). Continue by following and completing the START-UP / NEW
INSTALLATION / WARRANTY / ANNUAL TESTING FORM.
Note:
See CARB Executive Order VR-201 for complete installation, operation, and maintenance (IOM) details.
