Pump installation and warranty guide for
CombiBoost
Important – read this first!
The CombiBoost has two separate and distinct applications. The first is for use on the
incoming domestic cold water mains supply, and the second is directly on the combi-boiler
cold water inlet.
CombiBoost™ is designed to boost your existing incoming mains water supply up to 10 litres
per min (lpm). The intelligent control ensures that it reacts and responds to give a stable
outflow, and is unrestrictive if your natural water flow reaches 10lpm or more naturally.
Correct installation is essential for safe operation and a trouble free system. It is therefore
important to read these instructions thoroughly and ensure that you comply with them.
Incorrect fitting will invalidate the warranty.
If your installation is complicated or you have any questions, please consult the PumpWise
Technical Helpline immediately (0191 516 2002).
We encourage installers to consult the Salamander helpline before installation, where our
technical advisers can give you professional advice regarding installation. When the job is
finished, please complete the warranty registration on our website
www.salamanderpumps.co.uk or by calling 0191 516 2002.
Please leave this installation guide with the customer for reference to maintenance and
safety information.
Thank you for choosing

Pre-installation checklist
CombiBoost is suitable for two separate types of water boosting 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.
Points applicable to either installation type:
Do’s
• CombiBoost must be fitted to rigid fixed
pipework preferably with vertical inlet and
outlet
• Pipework above and below the pump must
be securely fixed to the wall
• Only one CombiBoost may be fitted per
household supply
• Ensure that installation complies with IET
Wiring Regulations
• Allow 100mm on all sides for ventilation
• Ensure pump is protected from frost
• Complete all hot work prior to
CombiBoost installation
• We recommend that the pump is activated
for at least five minutes every four weeks
• If the supply is known to be lime/calcium
(hard) water, fit extra filtration before the
pump. Always consult filter manufacturer’s
literature for correct installation.
Don’ts
• Never fit to hot water piping
• Never fit the pump to communal risers
• Never pump directly from or to another
pump – only one CombiBoost may be
installed per household supply
• Never fit to flexible pipework (e.g. tap
connectors)
• CombiBoost cannot be used on outside
coldwater storage tanks, bore holes or
wells
• Never use jointing compounds,
Boss White, hemp or steel wool
• Solder fluxes must not come into
contact with the pump
• Never fit to restrictive or collapsed
supply (eg lead main)
• Never fit CombiBoost upside down
Points applicable to whole house installation:
Do’s
• Install vertically or horizontally,
mounted on cold water mains inlet to
the house
• Locate the pump next to the mains
stop tap
• Pump should be fitted before ANY other
water outlets taken after the mains stop
tap. If any outlets are between the stop
tap and your CombiBoost, they must be
fitted with a non-return valve (NRV).
Points applicable to combi-boiler installation:
Do’s
• Install vertically or horizontally, mounted
on cold water mains inlet to the combi
boiler
• Locate the pump next to the combi-boiler
OR on it’s cold water mains inlet
• Pump must exclusively feed the combi-
boiler

Application notes
Please follow these pre-installation instructions carefully. Failure to install your CombiBoost
in accordance with these instructions will invalidate your warranty.
1. Location of CombiBoost
The best possible location of the CombiBoost is on the cold water mains supply to the house,
by the mains stop tap or the combi boiler inlet, depending on the installation.
1.1 Cooling and ventilation
The CombiBoost should be placed in a position where there is adequate air flow to cool the
motor and separated from any other appliances that generate heat.
1.2 Frost protection
CombiBoost must be protected from frost damage.
2. Cold supply to the CombiBoost
CombiBoost must be fitted directly to the cold water mains house supply, or the mains
water inlet to the combi boiler as indicated in the pre-installation checklist. Never fit to
communal risers (e.g. block of flats), restrictive or collapsed supply pipework (eg lead main)
or secondary circuits that are pumped.
3. General plumbing
Please note that the CombiBoost is designed to boost incoming water flow under low
pressure conditions. It cannot overcome restricted incoming pipework and replacement
water pipes should be installed in this scenario.
Installation must comply with the relevant requirements or local byelaws.
It is recommended that CombiBoost is installed vertically, and every effort should be made
to accommodate this. However, CombiBoost will function correctly if installed horizontally. It
must be adequately vented, protected from frost, and with access provided for servicing.
Jointing compounds, Boss White, hemp and steel wool MUST NOT BE USED. SOLDER
FLUXES MUST NOT COME INTO CONTACT WITH THE PUMP. THIS WILL INVALIDATE YOUR
WARRANTY.
Supplied inlet strainer must be fitted to the inlet supply of the CombiBoost. All outlets which
are located between the mains stop tap and the CombiBoost must be protected by non-return
valves. This is to prevent backflow of water and air from these outlets to the CombiBoost,
which will cause damage to the pump.
Suitable for maximum inlet pressure of 1MPa (10 bar).
In line with good plumbing practice and Water Regulations, ensure that a non-return valve
has been fitted directly after the mains stop tap to the house. Earth continuity must be
maintained with 4mm2earth connection cable.

Application notes – continued
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. To install immediately after the stop
tap, the isolation valve should be fitted to the pump outlet. To install before a combi boiler
only, the isolating valve should be fitted to the pump inlet.
5. Holding the CombiBoost during installation
To hold the CombiBoost during installation, spanner flats (24mm) have been provided on the
brass neck outlet. See Figure 1. Any tool used to hold the CombiBoost 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 CombiBoost 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.
CombiBoost 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.

Commissioning
Before you finish
• Check the pump inlet filter is fitted
• With the 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 using natural flow before switching the
pump on electrically, via:
1. all the cold outlets on a whole house application.
or
2. all the hot outlets for a combi boiler boost application.
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 boosting installation)
6 Inspect connecting pipe work for leaks
7 Plug in electrical supply to pump
8 Turn mains electrical supply on
9 Turn a cold outlet on (or hot outlet for a combi boosting application)
10 CombiBoost should activate and the flow should increase, indicating that the pump
is in operation.
If the CombiBoost does not activate, please refer to the troubleshooting section of these
application notes.

General specifications
Applications
The CombiBoost pump is designed to boost low mains water pressure into a domestic house
to improve low water flow from the mains supply at peak demand times. It 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.
CombiBoost will increase the low incoming water flow up to 10 l/min which complies with
the Water Supply (Water Fittings) Regulations 1999. As the incoming flow varies, the
CombiBoost will adapt to maintain 10 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
With the technical advances achieved in the CombiBoost pump, Salamander has taken
another step forward in supplying all our customers with even quieter centrifugal pumps.
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. Your pump will also activate itself for a few seconds
following 12 hours of inactivity to aid this.
Connections
¾” BSP male.
Initiation
Fully automatic, water flow operated, requiring 3 litres per minute flow rate to initiate.
Temperature
CombiBoost is suitable for cold water use only. Maximum fluid temperature is UK cold water
mains temperature (max 20°C).
