Pre-installation checklist

HomeBoost™ and CombiBoost are 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

• HomeBoost™/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 HomeBoost™/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 fitting prior to HomeBoost™/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
• Never fit to flexible pipework (e.g. tap connectors)
• HomeBoost™/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 HomeBoost™ /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 HomeBoost™/CombiBoost, they must be fitted with a non-return valve

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 HomeBoost™/CombiBoost in accordance with these instructions will invalidate your warranty.

1. Location of HomeBoost™/CombiBoost
   The best possible location of the HomeBoost™/CombiBoost is on the cold water mains supply to the house, after the mains stop tap or on the combi boiler inlet, depending on the installation.

2. Cooling and ventilation
   The HomeBoost™/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.

3. Frost protection
   HomeBoost™/CombiBoost must be protected from frost damage.

4. Cold supply to the HomeBoost™/CombiBoost
   HomeBoost™/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).

5. General plumbing
   Please note that the HomeBoost™/CombiBoost is designed to boost incoming water flow under low pressure conditions.
   Installation must comply with the relevant requirements or local byelaws.
   It is recommended that HomeBoost™/CombiBoost is installed vertically, and every effort should be made to accommodate this. However, HomeBoost™/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 HomeBoost™/CombiBoost. All outlets which are located between the mains stop tap and the HomeBoost™/CombiBoost must be protected by non-return valves. This is to prevent backflow of water and air from these outlets to the HomeBoost™/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.

6. 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 to a combi boiler only, the isolating valve should be fitted to the pump inlet.

7. Holding the HomeBoost™/CombiBoost during installation
   To hold HomeBoost™/CombiBoost during installation, spanner flats (24mm) have been provided on the brass neck outlet. See Figure 1. Any tool used to hold HomeBoost™/CombiBoost while the pipework is connected must be located on the brass portion of the neck to avoid damage to the polymer pump body.

8. Electrical requirements
   HomeBoost™ /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.
   HomeBoost/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.

Typical installations

Commissioning

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).

Standards and approvals
