Any components such as hose, 
nozzle, or pump added to your me-
ter must be statically grounded and 
approved for use with petroleum 
fuels.

1.   Remove protective plugs from meter 
      inlet and outlet ports.

2.   Wrap  threaded  male connections 
      with thread tape or use a pipe sealant 
      compound compatible with petroleum 
      fuels.

3.    Install the meter on the pump. The 
       meter’s outlet port is marked with a 
       flow arrow.

4.    Install other system components on
       the meter and tighten snugly.

Meter Accuracy

The meter has been accurately calibrated at 
the factory for use with diesel fuel. Due to 
differences in viscosities and flowrates, 
calibration  may  need to be adjusted if other  
fuels  are  to be dispensed. Refer to the 
Repair Section for calibration instructions.

INSTALLATION

1.  Before use, visually check the meter to 
     ensure it is securely fitted to other system 
     components and there is no leakage at 
     connections. If leakage is present, refer to 
     the Troubleshooting Section.

2.  Follow safety precautions, wiping any spilled 
     fuel from the exterior of the meter and other 
     system components.

DAILY OPERATIONS

    Dispense Fuel

This meter is designed for use only with 
thin viscosity petroleum fuels such as 
diesel fuel, kerosene  and gasoline 
(up to 15% alcohol blends such as E15, 
M15). Do not use this equipment for
dispensing any fluids other  than those  
for  which  it was designed. To do so may 
damage the meter and will void the
 warranty.

Observe precautions against fire or 
explosion when dispensing fuel. Do not 
operate the meter in the presence of any 
source of ignition including running or 
hot engines, lighted cigarettes, or gas or 
electric heaters.

Avoid prolonged skin contact with
petroleum fuels. Use protective goggles, 
gloves, and aprons in case of accidental 
splashing or spillage. Change saturated 
clothing and wash skin contact  areas  
promptly with soap and water.

Your system must be mounted to a vented
 tank. (Figure 1)
