1 INTRODUCTION

1.1 Congratulations on buying a Mainsboost system, designed to offer consistent

and reliable water services throughout the property and the only system available

that is patent protected No. GB2349908.

1.2 Patents, Trademarks & Trade Names:

‘Mainsboost’ ‘Mainsboost Plus™’ and ‘Mainsboost Charger’ are

registered Trademarks of Stuart Turner Ltd.

The use of this system is patent protected and the Mainsboost vessel cannot

be mixed with other accumulator systems without prior approval from

Stuart Turner Ltd.

The Mainsboost vessels have special characteristics and the use of other

vessels in this application could prove to be detrimental to the design and

performance of the system and the patent.

Stuart Turner Ltd will treat any infringement of the patent very seriously and

therefore recommend that any questions regarding application be brought to the

company for consideration.

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.

3 LOCATION - GENERAL

3.11 Access: For emergencies and maintenance the Mainsboost must be

easily accessible.

3.12 Protection: 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: The incoming water pressure of at least

1.5 bar is required and should not exceed 5 bar.

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 System Designation:

It is important to understand what upstream and downstream refers to before

starting the installation.

4.12 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.

4.13 Downstream

The term ‘Downstream’ refers to the system configuration from the outlet tapping

on the Mainsboos 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 patent protected packaged

system to suit any type or size of building no matter how large or small the

demand is. The following illustrations depict just 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 (see

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 again 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

(see 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.

6 INSTALLATION

Step 1:

Remove the Mainsboost vessel from its packaging and check to ensure it is not

damaged.

zWARNING: depending on cylinder size this may require two

people to complete safely.

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.

6.11 Vertically mounted Mainsboost vessels

a) Carefully turn the vessel on its side using the discarded packaging to protect

it.

b) Once on its side screw the Mainsboost vessel connector (item 3) provided in

the upsteam line-in kit into the tank elbow at the base using suitable thread

seal such as PTFE tape or liquid thread lock (see Fig. 9).

c) Cut a piece of 28 mm dia. copper pipe to the following minimum length,

ensuring clearance of the base.

Pipe length:

MB 100SV = 210 mm MB 200SV = 270 mm MB 300SV = 270 mm

MB 130SV = 210 mm MB 250SV = 270 mm MB 450SV = 340 mm

Then re-erect the cylinder.

d) Fit the isolating valve provided to the tail now protruding from the base of the

vessel.

e) The vessel assembly should then be positioned and checked to ensure

there is sufficient space to install the upstream line-in kit between the

stopcock and pressure vessel inlet. Refer to the chart (Fig. 17) as a guide.
