Installation

Installation
This dispense valve must be calibrated after installation
(beginning on page 14). Dispense amounts vary with
fluid pressure, temperature, and type of fluid
dispensed.
This dispense valve is designed for indoor use only, for
use with industrial grade batteries (see page 21), and is
not designed for in-line installation.
Grounding
Pump: follow the manufacturer’s recommendations.
Hose Reels or consoles : connect to a true earth
ground.
Fluid hoses: use only conductive hoses when
dispensing petroleum products.
To maintain grounding continuity when flushing or
relieving pressure, hold a metal part of the valve firmly
to the side of a grounded metal pail, then trigger the
valve.
Pre-Installation Procedure
1. Install the battery. See Replace the Battery ,
page 21.
2. Follow the Pressure Relief Procedure , page 10.
3. Close the shut off valve (B) (F
IG
. 1, page 6).
4. Ground the hose and reel or counsel. See
Grounding .
NOTE: Leave at least two engaged threads bare when
using PTFE tape, the bare threads ensure ground is
maintained.
Installation Procedure
For existing installations, skip to Electronic Control (1)
and Gasket (2) Installation , page 8.
Flush the System
1. Close the fluid shut off valve (B) at each dispense
position (F
IG
. 3).
2. Make sure that the main fluid outlet valve at the
pump is closed.
3. Adjust the air pressure to the pump motor.
a. Adjust the air regulator attached to the motor
air inlet.
b. Open the air valve.
c. Slowly open the main fluid valve.
4. Flush the system:
a. Place the hose end (no dispense valve
connected) into a container for waste oil.
b. Secure the hose in the container so it does not
come out during flushing.
c. For multiple dispense positions, start with the
dispense position furthest from the pump, and
work toward the pump.
5. Slowly open the shut off valve (B) at the dispense
position and flush out a sufficient amount of oil to
ensure that the entire system is clean (F
IG
. 3).
6. Close the shut off valve (B) (F
IG
. 3).
7. Repeat steps 5 and 6 at all of the dispense
positions.
The equipment must be grounded to reduce the risk
of static sparking. Static sparking can cause fumes
to ignite or explode. Grounding provides an escape
wire for the electric current.
NOTICE
For new installations, or when there is contaminated
fluid in the lines, flush the lines before installing the
meter valve, to avoid valve leakage.
