PIPEWORK
WARNING
Ensure pipework from pump is independently supported to prevent forces
being transferred to outlet branch.
General
All models are supplied with a stepped hose connector (see pump connection section
for details) which can be screwed directly into the pump discharge connection.
The hose connector is suitable for a range of flexible hose sizes and can be cut to suit
the selected size. For best flow use the largest bore pipe possible minimising 90° bends.
Small pipe sizes will reduce the pump performance.
The discharge pipework must be independently supported to prevent forces being
transferred to the pump outlet branch.
Diver
These models are supplied with a non-return valve which should be screwed directly
into the pump outlet port (see pump connection section for details). The purpose of the
valve is to limit back flow and pressure on the pump and ensure discharge pipework is
always primed with water.
ELECTRICAL INSTALLATION
WARNINGS:
The electrical installation must be carried out in accordance with the
current national electrical regulations and installed by a competent
person.
A residual current device having a rated current not exceeding 30 mA
MUST be installed in the supply circuit. This may be part of a
consumer unit or a separate unit.
Before starting work on the electrical installation, ensure the power
supply is isolated.
This appliance must be earthed.
Isolate all appliances in the water from the electrical supply before
putting your hands in the water.
The power supply cord of this pump cannot be replaced. If the cord is
damaged, the pump should be scrapped.
If the pump is used to empty a swimming pool, the pump must not be
used when people are in the water.
The standard pumps are suitable for a supply of 230V, 1 phase, 50Hz. Other
frequencies (60Hz) are available on certain models and it is therefore very important to
ensure the pump rating plate details match the supply.
All motors are thermally protected by an integral auto-resetting thermotrip and are rated
for continuous use.
Earthing
This appliance must be earthed via the supply cord.
