4. Isolation valves
Good plumbing practice is to fit full bore
isolating valves into the inlet and outlet pipe
work of the pump to facilitate service and
removal of the pump. The fittings supplied
include one full bore isolation valve and
one loose flange tap connector. To install
immediately after the stop tap, the isolation
valve should be fitted to the pump outlet.
To install to a combi boiler only, the isolating
valve should be fitted to the pump inslet.
5. Holding the HomeBoost
™
during installation
To hold the HomeBoost
™
during installation,
spanner flats (24mm) have been provided
on the brass neck outlet. See Figure 1. Any
tool used to hold the HomeBoost
™
while the
pipework is connected must be located on the
brass portion of the neck to avoid damage to
the polymer pump body.
6. Electrical requirements
The HomeBoost
™
must be connected to
the electrical supply using the mains cable
with the attached plug. This plug must be
connected to an accessible socket that
has been installed in compliance with
IET Wiring Regulations.
The plug must be accessible at all times.
If the supply cord is damaged, it must be
replaced by the manufacturer, it’s service
agent, or similarly qualified person in order to
avoid a hazard.
All pipe work must be cross-bonded in
accordance with the IET Regulations.
HomeBoost
™
is supplied with a 3A fuse fitted.
Higher rated fuses MUST NOT be used.
If installed by a Part P qualified installer, the
pump may be fitted via a 3A fused mains spur
without invalidating the warranty.
