7.8 Performing a Test Run

Once the system is properly wired and plumbed,
but before filling the enclosure with water, perform
a test run to ensure proper operation.
A test run includes testing the drum and backwash
pump motors by turning the power on and off and
by using the Manual Mode switch on the control
panel to verify correct rotation.
7.8.1 Procedure
1. Remove lid panels.
2. Observe the area for any personnel or objects
that could be caught in a rotating part.
3. Turn on power to the Rotofilter control panel.
The "Power" LED on the top of the control panel
should illuminate.
If the LED does not illuminate,
the control panel has not been
properly wired. Turn off power.
A licensed, professional electrician will need to
identify the problem.
4. Remove the pump plumbing on the suction end.
Fill the pump volute (the centrifugal casing) with
water. If the pump has been placed high enough
that water will not stay in the volute, the Rotofilter
enclosure or sump will need to be filled until the
volute stays filled.
Do not run the pump before the
volute is filled. Running the pump
when it is dry will cause damage
that is not covered by the warranty.
5. Reattach the suction end of the pump plumbing.
6. Ensure the backwash throttling valve is fully
closed. Open the backwash pump supply
isolation valve.
7. Open the backwash throttling valve
one-quarter turn.
8. Turn the pump and backwash switches from
Off to Manual. The "Drum Run" and "Backwash
Pump Run" LEDs should illuminate. The drum
should begin rotating and the backwash system
should begin operation. If the LED does not
illuminate or rotation does not occur, the control
panel has not been properly wired.
