Before you finish
• Check the pump inlet filter is fitted
• With HomeBoost™/CombiBoost installed, flush the inlet pipe work and fully fill the pump with
water by opening all the water outlets BEFORE electrically switching the pump on.
It is critical to discharge water through the pump through;
1. all the cold outlets on a whole house application.
or
2. all the hot outlets for a combi boiler boost application. Using natural flow before switching the
pump on electrically. This will ensure that the air has been discharged from the connecting pipe
work and pump chamber.
The best method is:
1 Connect pump pipe work
2 Check that all isolating valves are open
3 Turn mains water on at the stop tap
4 Ensure all air is purged from the system
5 Check for natural flow on the cold outlets (or hot outlets for a combi boost installation)
6 Inspect connecting pipe work for leaks
7 Plug in electrical supply to pump
8 Turn mains electrical supply on
9 Green pump lights in the logo label should be lit and steady. This indicates that the power
is on and that the pump is ready for use (HomeBoost™ only)
10 Turn a pumped outlet on
11 HomeBoost™/CombiBoost should activate. The green lights should rotate, indicating
that the pump is in operation (HomeBoost™ only).
If the HomeBoost™/CombiBoost does not activate, please refer to the
trouble shooting section of these application notes.
General specifications
Applications
HomeBoost™/CombiBoost pumps are designed to boost low mains water flow into a domestic
house to improve low water flow from the mains supply at peak demand times. These pumps can
be used in two distinct applications:
1. Boosting the incoming mains water supply to a whole house
2. Boosting the inlet mains water supply solely to a combination (combi) boiler.
HomeBoost™ will increase the low incoming water flow up to 12 lpm and CombiBoost will increase
to 10 lpm which comply with the Water Supply (Water Fittings) Regulations 1999. HomeBoost™
will adapt to maintain 12 l/min, and will move into idle if sufficient flow is received from the water
main.
Power supply
230 volts, 50Hz, 1.8A, continuously rated.
Pump noise
The HomeBoost™ pump has been awarded the quiet mark, demonstrating that it is one of the
quietest pumps available in its category. However, no pump is completely silent and this type of
pump is characterised by a high pitched hum or whine.
Mechanical seals
Scale deposits in water supplies can cause the mechanical seal to stick if left for long periods
without use. We recommend that the pump be run for at least five minutes every four weeks to
‘exercise’ all the working parts.
Connections
¾
” BSP male.
Initiation
Fully automatic, water flow operated, requiring 3 litres per minute flow rate to initiate.
Temperature
Maximum fluid temperature is UK cold water mains temperature (max 20°C).
