c) Electrical connections
Ensure that the pump is disconnected from the power supply during
installation, or before moving or servicing the pump.
Dominator pumps are supplied with a unique Onga IEC weatherproof connector.
Your Dominator pump kit will have all the necessary electrical connections to allow
you to plug the electrical cord into a 10A General power outlet. The Dominator
pump has a double ground contact to this connection, the pump is grounded
when the plug is connected to a grounded power supply
The power cord is not a user servicable item. It must be replaced by the
manufacturer using special tools
The pump is supplied with an in-built thermal circuit breaker with automatic reset.
All electrical work must be carried out in accordance with local regulations.
The power supply must be fi tted with a residual current device (earth leakage
protection) with sensitivity of 30mA or less.
d)
Discharge
The length and diameter of the discharge lines will affect the pressure and fl ow
rate at which your pump operates. Care should be taken when selecting discharge
pipe/hoses and fi ttings. Pressure ratings of all components must exceed the
maximum pressure of the pump by an appropriate safety factor.
e)
Dominator suction has been intentionally raised to alleviate sediment being
pumped. to raise this height further, use 3” PVC pipe and insert into specially
designed base.
5. OPERATION
Ensure that your pump is submerged before operating.
Connect discharge piping, and ensure that the suction is completely submerged.
Connect to power and pressure control device (if required).
Do not submerge the pressure control device (if installed).
Do not submerge the electrical connectors.

3. Application
Dominators are multistage submersible pumps. They are suitable for use in clean
water without dissolved gasses. The pump components are suitable for use with
potable water.
4. Installation
a) Preparation for operation
Read these instructions fi rst
Inspect your pump for shipping damage. Report any damage to your Pentair
Water dealer no later than 8 days from purchase date.
Ensure that the electrical supply has suffi cient voltage and current capacity.
b) Pump Protection
Warranty of these pumps is void unless they are operated in accordance with this
owners manual. Avoid using an electrical cable to lift or transport the pump. Use the
nylon rope supplied or a stainless steel cable to support the pump. It is advisable to
connect the electrical cable to the delivery line at three metre intervals.
It is advisable to fi t automatic level controls to prevent the pump running without
liquid, and a pressure gauge to verify operation.
