Installing the Metering Pump (continued)
Alternate Mounting: Horizontal Positioning
ATTENTION: If the metering pump is to be mounted horizontally or on a bracket as shown in
Figure 4I, the pump head must be rotated counterclockwise so that it is aligned in a horizontal position.
The gauge arrow on the pump head must point up, or the pump will not prime.
1. Refer to Figures 4H and 4I.
2. Remove the two pump mounting bolts. The coupling is keyed and does not have set screws.
3. Rotate the pump head 180 degrees to the horizontal position as shown in Figure 4I.
4. Re-install and tighten the two pump mounting bolts.
5. Use the appropriate type of bolts and washers (user-supplied) to securely mount the metering
pump to the mounting bracket, which is to be installed on the appropriate wall in your building at a
distance from the tank that complies with the suction oil line requirements.
