5. Meter installation
5.1
Relieve system pressure
1. Turn off the power supply to the pump or close the shutoff valve.
2. Dispense any fluid in the system into a waste container by opening the meter(s).
3. Open all bleed-type master air valves and fluid meter(s) in the system.
4. Leave the meter(s) open until ready to pressurize the system.
Pressurized equipment
This equipment stays pressurized until the pressure is manually relieved. To reduce the
risk of injury from fluid spray from the meter follow the pressure relief procedures when
you:
• Are instructed to relieve pressure
• Stop dispensing
• Check, clean or service any system equipment
• Clean or install nozzles
5.2 Grounding
1. Grounding reduces the risk of static sparking. Ground all system components
according to local, state, and federal codes. Consult the pump user's manual and
other system components to ground the following:
2. Pump: follow manufacturer's recommendations
3. Air and Fluid Hoses: use only grounded hoses
4. Air Compressor: follow manufacturers recommendations
5. Fluid Supply Container: follow the local code
Explosion and fire
Movement of fluids through the dispensing system creates static electricity. Static
electricity can cause volatile fumes resulting in an explosion and fire. The dispensing
system must be grounded.
5.3
Flushing procedure
NOTE:
If the system has multiple dispense positions, begin at the position farthest from
the pump and move towards the pump.
1. Close fluid dispense valves at every position.
2. Once the main fluid outlet valve at the pump is closed and the air pressure to the
pump motor is properly adjusted, the air valve is opened.
3. Slowly open the main fluid valve.
4. Place the hose end in a waste container. Make sure hose is secure so no fluid leaks
during flushing.
5. Slowly open the dispense valve and allow enough fluid to pass through it to ensure
that the system is clean.
6. Close the valve and repeat for all dispense positions.
If this installation is new or if the fluid in the lines is contaminated, flush the system before
installing the meter(s).
