INSTALLATION, OPERATION, AND MAINTENANCE

Installation

1. Remove packaging and inspect for shipping damage. Note any shipping damage on the
shipping ticket and notify Earthsafe within 24 hours of receipt.
2. Set unit at installation location. Use proper handling procedures to avoid damage to
the unit.
3. Install anchor bolts at 4 corners. Use ½" diameter expansion anchors with 3" embedment or
as required for local code compliance.
4. Connect power to motor starters and controller. Reference specific installation instructions
and wiring diagrams for the controller and motor starter panels.
5. Check tightness of all bolts, which may have loosed during shipment. Tighten 4 bolt flanges
by gradually tightening across the bolt pattern.
6. Pressure test the pump set to 50 PSI or in accordance with project design requirements.
Correct any loose bolts or threaded joints if required. The day tank is not rated for
pressure over 5 PSI, so piping to be tested must be isolated from the tank using valves or
other means.
7. Clean field installed piping. Clean all dirt and debris from field installed piping prior to
connecting to the day tank.
8. Connect piping to inlet and outlet (inlet piping considerations). Confirm that field piping
is independently supported to avoid stress on the pump set piping.
9. Check pump rotation. Energize the pump momentarily to observe direction of motor fan
rotation. The pump inlet and outlet are offset from the centerline of the pump head, so that
there is a long arc or short arc from the inlet to the outlet. The pump rotation should be
that it progresses along the long arc from the inlet to the outlet.
10. Engine supply and return piping should include rated hoses or flexible connectors to isolate
vibration from the day tank.
11. Vent piping shall be installed to terminate to the building exterior. The vent piping should
slope continuously from the termination point back to the day tank.
12. Where a return flow pump is used, and the main fuel tank is below the day tank, an
anti-siphon valve must be installed on the return flow pump discharge.
