INSTALLATION ADVICE - GRAVITY FED SET-UP
1. The pump suction line should be not smaller than 1½” (40mm imperial)
or 50mm true metric.
2. We recommend using Single Unions, Threaded Female To Plain Female,
to connect to Pressure Pipe (see page 8 for advice).
3. The suction line is to have as few bends or elbows as possible. There must not
be an air trap on the suction line.
4. Tighten the pump fittings only as much as is required to ensure a tight connection.
Excessive torque is unnecessary and may cause damage to the pump.
5. All wiring (electrical) work must be carried out by a qualified electrician and must
be installed in accordance to the local codes.
6. The motor must be earthed.
7. The weight of the plumbing and fittings is to be independently supported and not
carried by the pump.
8. The pump is not self-priming. Therefore, if the water level is below the pump,
a non-return valve must be installed below water level. The pump and inlet line
must be primed prior to start up. For non-flooded installations a check valve
(non-return valve) is recommended.
9. The controller must not be submerged in water.
10. Do not operate the pump without water.
