Installation
Do not attempt to start the pump until the storage tank has been filled with water and the pump primed and vented.
All electrical connections should be carried out by a qualified and authorised electrician in accordance with the latest issue
of the I.E.E. regulations. The Home Booster must be earthed. It is strongly recommended that an Earth Leakage Circuit
Breaker (ELCB) is fitted on the incoming electrical supply.
Do not remove pump motor terminal box, motor fan or PM2 covers unless electrical cables or any other electrical
protective covering without first ensuring that the electrical supply is suitably isolated and cannot be switched on.
Do not attempt to supply electricity to the Home Booster and run the pump without ensuring that all electrical fittings,
cables and enclosures are intact and suitably electrically isolated from human touch during operation.
Do not attempt to supply electricity to the Home Booster without first ensuring that the motor fan covers are correctly fitted
and held securely inplace.
GENERAL INFORMATION
1. The discharge pipework must be at least the same size as the booster set connection size 22mm, as a smaller size may result in
reduced pressure and flow at the outlets.
2. The installation discharge pipework must be properly supported
before
being connected to the booster set so that the booster set
internal pipe work is not stressed.
3. The pipework installation from the booster set should be in accordance with local water authority regulations.
4. The electrical installation of the booster set should be in accordance with the latest issue of the I.E.E. regulations.
5. Check that the cold water storage tank has adequate capacity to meet the water consumption demand.
WATER QUALITY
Consideration must be given to maintaining the quality of the water stored within the Home Booster tank, and indeed any other
stored water arrangement, in order to ensure that the water remains fit for use. The quality of stored water will deteriorate with time,
bacterial growth is dependant on the ambient air temperature, growth rates will be higher when the conditions are warm. The tank
should drained and flushed, if the water remains unused for an extended period.
As with any stored water arrangement, it is recommended that the storage tank(s) is cleaned and disinfected annually, in order to
remove accumulated debris which could provide a habitat for bacterial growth. The water within the unit should be sampled
periodically to check bacterial levels, generally between two and four times a year is recommended.
LOCATION
The Home Booster must not be installed into roof spaces.
The small level of vibration associated with any rotating
equipment will cause disturbance, and considerable water damage could result if a leak occurs. Please provide drainage
facilities for the unit in case of leakage or loss of water during commissioning and service.
1. The Home Booster set should be sited in a dry, well ventilated, and frost-free position, where it will not be subjected to extremes
of temperature. In order to reduce bacteria growth the ambient temperature should ideally be less than 20
°
C. The Home Booster
may be located outdoors in a weather, frost and rodent proof enclosure with adequate ventilation especially during hot weather.
2. All pipe work subject to freezing conditions must be adequately protected.
3.
Ensure that the Home Booster is positioned to allow access for examination and service.
4. Please provide adequate drainage facilities and protection from water damage in the immediate vicinity of the booster set.
5. To enable maintenance and service of the unit to be carried out satisfactorily, the area should have adequate lighting for this work
to be carried out safely.
6. The Home Booster should not be installed in an unventilated small space to ensure adequate ventilation for the motor.
FOUNDATION & MOUNTING
The Home Booster should be mounted on a solid foundation capable of supporting the weight of the unit. The supporting surface
must be flat and level to avoid distortion of the tank.
The recommended support arrangement is a concrete plinth or floor.
Grundfos does not recommend installation of the Home Booster onto a wooden substrate.
Due to possible noise and
vibration transmission into the structure of the building. The ideal location is in a ground floor utility room or a garage with concete
flooring.
STORAGE TANK
The Home Booster has an integral cold water storage tank having a type AB Air Gap, and must be installed in accordance with the
Water Byelaws Regulations.
The quality of the water within the storage tank is potable and is therefore suitable for drinking. However, it should be
borne in mind that the quality of stored water will deteriorate with time, particularly if the ambient air temperature is high.
Therefore, if the unit is to be left for an extended period of time it is recommended to completely drain the storage tank
before it is left.
Check that the tank cold water storage tank has adequate capacity to meet the demand of the users within the building. As a
general rule, allow 125 litres storage per person. Alternatively the storage can be based on the number of bedrooms, in which case
multiply 125 litres by the number of bedrooms plus one.
A person will use approximately 150 litres per day, for standard fittings and use. Where space is restricted the amount of storage
can be reduced on the basis that half of this volume is used in the morning and evening.
The ability of the cold water mains supply should also be taken into account when considiering the size of the cold water storage
tank.
