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.
7. Connect piping to inlet and outlet (inlet piping considerations). Confirm that field piping
is independently supported to avoid stress on the pump set piping.
8. 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.
