Pipework Connections (Hot Water)
(RGFL, RGDFL and ESFL range)
These pumps should have a minimum of 22 mm pipework throughout the system.
The supply must be air free and connection to the cylinder can be made by one of the
following methods shown.
When method of connection is to be via the expansion pipe, the cold water storage
cistern should be at least 1 metre above the top of the hot water cylinder.
ELECTRICAL INSTALLATION
WARNINGS:
 The electrical installation must be carried out in accordance with the
current national electrical regulations and installed by a competent
person.

In the interests of electrical safety a 30 mA residual current device
(R.C.D.) should 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.
 The motor and wiring must not be exposed to water.
 Do not allow the supply cord to contact hot surfaces, including the
motor shell, pump body or pipework. The cord should be safely
routed and secured by cable clips.
The motor fitted to this pump is suitable for a single phase 230V, 1 phase, 50Hz supply.
It is thermally protected by an integral auto resetting thermotrip for your safety. The pumps
are rated for the duty listed in the technical specification section.
