Meter Installation

Pressure Relief Procedure

1.

Turn off the power supply to the pump.

2.

Trigger the dispense valve into a waste container to relieve pressure.

3.

Open any bleed-type master air valves and fluid drain valves in the system.

4.

Leave the drain valve open until you are ready to pressurize the system.

Installation Procedure

CAUTION

If this is a new installation or if the fluid in the lines is contaminated, flush the lines before you install the metered valve. Contaminated lines could cause the valve to leak. Failure to flush will void any warranties.

Follow steps 1 through 6 of the Flushing Procedure below.

WARNING

Fire and Explosion Hazard

The movement of fluids through the dispensing system generates static electricity.

The static electricity can cause volatile fumes to ignite, resulting in explosion and fire. The dispensing system must be grounded. See Grounding

on page 9.

Pre-Installation Procedure

1.

Relieve the pressure.

WARNING

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on

page 7.

2.

Close the shut-off valve (J). See F IG . 2.

3.

Ground the hose and reel or console. See Grounding

on page 9.

If the fluid lines do not require flushing, go to step 6.

Steps 1 through 6 are the

Flushing Procedure .

1.

Close the fluid shut-off valve (J) at each dispense

position. See F IG . 2.

2.

Make sure the main fluid outlet valve at the pump is closed, the air pressure to the pump motor is adjusted, and the air valve is open. Slowly open the main fluid valve.

3.

Place the hose end (with no dispense valve connected) into a container for waste oil. Secure the hose in the container so it will not come out during flushing. If you have multiple dispense positions, first flush the dispense position farthest from the pump, and work your way toward the pump.

4.

Slowly open the shut-off valve (J) at the dispense position. Flush out a sufficient amount of oil to ensure that the entire system is clean, and close the valve.

5.

Repeat step 4 at all other dispense positions.

Calculating the Calibration Factor

Use the following tables and formulas to calculate the change to the calibration factor.

Example of Calibration Adjustment for Motor Oil (quarts - 368)

Dispense into a clean, calibrated, volumetric measuring flask until the meter display indicates 1 quart of fluid has been dispensed.

NOTE : For greater accuracy, submerge the nozzle and let the air settle out of the fluid for ten minutes before noting the volume.

• In this example, the flask shows the volume to be less than one quart (-1.2 ounces). See the left column and find the number closest to -1.2 ounce value which is 1.0.

• Look for the corresponding number in the right column, which is +12. If the current calibration factor is 368, add

12 to get the new calibration factor of 380.

• Change this factor for a fluid in Tank Setup and for a given meter(s) in Meter Setup.
