WARNINGS:
zMainsboost systems must not be used for any
other application without the written consent of
Stuart Turner Limited.
zThis appliance can be used by children aged
from 8 years and above and persons with reduced
physical, sensory or mental capabilities or lack of
experience and knowledge if they have been given
supervision or instruction concerning use of the
appliance in a safe way and understand the
hazards involved.
zChildren shall not play with the appliance.
zCleaning and user maintenance shall not be made by
children without supervision.
zEnsure the floor is sufficiently strong enough to
take the total weight of the unit when full of water
(see Technical Specification section). Take care when
manoeuvring the unit so as not to damage it.
zEnsure the unit is fixed to the floor using suitable
fixings to avoid risk of toppling over.
zTo prevent personal injury, ensure all water pressure
is released from the pressure system prior to
work being performed. Ensure pumps are
disconnected and/or electrically isolated.
zIt is strongly recommended that the system is
protected by a suitable pressure relief valve set at
or below the maximum vessel pressure rating. Failure
to install a pressure relief valve may result in vessel
explosion in the event of a system malfunction or
over pressurisation, resulting in property damage,
serious personal injury or death.
zIf the Mainsboost vessel leaks or shows signs of
corrosion or damage do not use it.
Please read the installation details carefully as they are intended to ensure this
product provides long, trouble free service. Failure to install the unit in accordance
with the installation instructions will lead to invalidation of the warranty. These
instructions must be left with the product.

1 INTRODUCTION
1.1 Congratulations on choosing a Mainsboost system, designed to offer
consistent and reliable water services throughout the property.
1.2 Trademarks & Trade Names
‘Mainsboost’ ‘Mainsboost Plus’ and ‘Mainsboost Charger’ are registered
Trademarks of Stuart Turner Ltd.
1.3 How the Mainsboost System works
The Mainsboost vessel stores water from the rising main in a sealed water
chamber, separated from the air space by a rubber diaphragm and
pressurised to an optimum setting. When water is drawn off by downstream
services, the water from the mains is supplemented by the water from the
Mainsboost unit to provide a balanced supply at consistent pressure to
downstream services.

2 IMPORTANT FACTS READ BEFORE COMMENCING INSTALLATION
A Water temperature
This unit is designed for cold water applications only which should not exceed the
following values:
2.11 The maximum allowable water temperature is 35 oC.
2.12 The minimum allowable water temperature is 4 oC.
B Pipework – General
2.13 Secure pipework: Ensure pipework to and from the Mainsboost is
independently supported & clipped to prevent forces being transferred.
2.14 Flux: Solder joints must be completed and flux residues removed prior to
completing the installation (flux damage will void any warranty).
2.15 Pipework design: Care should be taken in the design of pipework runs to
minimize the risk of air locks e.g. use drawn bends rather than 90obends.
C Plumbing Installation Regulations
2.16 The plumbing installation must comply with the current water and building
regulations.
2.17 The plumbing installation must be installed by a qualified person.
D Mainsboost vessel
2.18 Ensure the Mainsboost vessel is installed correctly before operating the unit,
to avoid damage.
Do not attempt to dismantle the Mainsboost vessel
The Mainsboost vessel is pressurised to a pre-set level at the factory see
Section 7.11 – Commissioning for details.
- 7 –
3 LOCATION GENERAL
3.11 Access: For emergencies and maintenance the Mainsboost must
be easily accessible.
3.12Protection: The system must be located in a dry position, and
protected from freezing. Avoid environments which have a high
ambient temperature, high humidity or excessive condensation
and salt damage, etc.
3.13 Incoming mains water pressure: An incoming water pressure of at least 2.0
bar is required and should not exceed 5 bar. (If mains pressure is below 2.0
bar the Mainsboost vessel should be supplemented with a pump unit, contact
Stuart Turner for details).
3.14 Ensure that location of the unit allows adequate space to give reasonable
access to all parts to accommodate service/commissioning.
3.15 Pipework: Pipework should be sized to ensure optimum performance of the
system.
3.16 Direction of flow: See Fig. 4 to identify the suction and discharge
connections.

4 TERMINOLOGY
4.11 Upstream Line-in Kits (ULK)
Monobloc upstream line-in kit:
The Mainsboost Monobloc is a patent pending mains regulating device
and should be installed on the rising main between the stopcock and the
Mainsboost vessel. The Monobloc unit is used on 22mm or 28mm upstream
line in kits.
Upstream line-in kits:
Upstream line-in kits for 35mm, 42mm & 54mm installations use separate
regulating components and should be installed on the rising main between
the stopcock and the Mainsboost vessel.
4.12 System Designation
It is important to understand what upstream and downstream refers to before
starting the installation.
Upstream
The term ‘Upstream’ refers to the system configuration from the consumer’s
stopcock to the point where the supply reaches the inlet port of the
Mainsboost vessel.
Downstream
The term ‘Downstream’ refers to the system configuration from the outlet
tapping on the Mainsboost vessel, along the distribution header (if configured
in this way) and into the distribution pipework and outlets. This includes hot
and cold services where both are present (see Fig. 4).

5 CONFIGURATION
5.11 Mainsboost is a very flexible solution, offering a packaged system to suit
any type or size of building no matter how large or small the demand.
The following illustrations depict some of the most typical installations.
5.12 Single occupancy application
Use of Mainsboost in a house
offers water on demand whilst
giving maximum flexibility.
As can be seen the upstream
line-in kit has to be fitted on to
the rising main but the vessels
can be fitted wherever there is
a space, for example; utility,
kitchen, upstairs cupboard or
loft, providing adequate
provisions are taken for the
weight, frost protection etc
(Fig 5).
Where height restrictions exist
the MB 200SH and MB 250SH
Mainsboost units can be
supplied suitable for
horizontal installation.
5.13 Multiple occupancy application
Often affected by poor water
supplies Mainsboost offers the
perfect solution.
For multiple occupancy buildings
the upstream line-in kit is located
next to the rising main and sized
to meet the demand of the entire
building. Each apartment then
has its own vessel located within
the property, sized to meet the
apartments own demand
(Fig. 6).

5.14 High demand single occupancy application
Where single properties have a much higher demand, it may be necessary to
use additional Mainsboost vessels connected in parallel to ensure sufficient
water is on tap to meet the much higher demand. Fig. 7 shows all vessels
being located in the same place.
5.15 Water softener
NOTE: If a water softener is to be fitted it must be located between the
upstream line-in kit and the vessel. If high pressure is also required to the
drinking tap fit a Stuart Water Conditioner, available from Stuart Turner, rather
than a water softener.
