1 INTRODUCTION

1.1 Congratulations on buying a Mainsboost Plus 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 Plus vessel

cannot be mixed with other accumulator systems without prior approval from

Stuart Turner Ltd.

The Mainsboost Plus 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 Plus System works:

The Mainsboost Plus pressure 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 Plus unit to provide a balanced supply at consistent pressure to

downstream services.

The Mainsboost Plus pipework manifold incorporates a unique ‘green energy’

bypass. If the incoming mains water supply delivers more than 12 l/min this

bypass should be left open to allow any additional flow rate to pass directly into

the Mainsboost pressure vessel via the integral non-return valve. If the

incoming flow rate is less that 12 l/min the bypass valve should be left closed

in order to ensure optimum efficiency of the Charger MJ3 pump.

2 IMPORTANT FACTS READ BEFORE COMMENCING INSTALLATION

A. Commissioning

2.11 Ensure the pump is primed as described in the priming section before starting,

damage to the shaft seal will result otherwise. See Section 8.16 -

Commissioning.

B. Water temperature

This unit is designed for cold water applications only which should not exceed the

following values:

2.12 The maximum allowable water temperature is 35 oC.

2.13 The minimum allowable water temperature is 4 oC.

C. Pipework - General

2.14 Secure pipework: Ensure pipework to and from the Mainsboost Plus is

independently supported & clipped to prevent forces being transferred to inlet

and outlet branches of pump. Flexible hoses supplied must be used.

2.15 Flux: Solder joints must be completed and flux residues removed prior to pump

installation (flux damage will void any warranty).

2.16 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.

D. Plumbing Installation Regulations

2.17 The plumbing installation must comply with the current water and building

regulations.

2.18 The plumbing installation must be installed by a qualified person.

2.19 The electrical installation must be carried out in accordance with the current

national electrical regulations.

2.20 The electrical installation must be installed by a qualified person.

E. Mainsboost vessel

2.21 Ensure the Mainsboost vessel is installed correctly before operating the unit, to

avoid damage to the pumps/controls.

Do not attempt to dismantle the Mainsboost vessel

The Mainsboost vessel is pressurised to a pre-set level at the factory see

Section 8.12 - Commissioning for details.

3 LOCATION - GENERAL

3.11 Access: For emergencies and maintenance the Mainsboost Plus

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 Ventilation: Ensure an adequate air flow to cool the pump.

Separate the pump from other appliances that generate heat.

3.14 Safety: The motor casing can become very hot under normal

operating conditions. Care must be taken to ensure it cannot be

touched during operation.

3.15 Water retention: Site the pump in a location where in the unlikely

event of a water leak, any spillage is contained or routed to avoid

electrics or areas sensitive to water damage.

3.16 Static inlet pressure: Ensure the static inlet head at the pump does not

exceed the values shown in the table under point 8.14.

3.17 Incoming mains water pressure: The incoming water pressure of at least

0.1 bar is required.

3.18 Ensure that location of the unit allows adequate space to give reasonable access

to all parts to accommodate service/commissioning.

3.19 Ambient temperature: The pump must be sited in a location where the

maximum ambient temperature does not exceed 40 oC.

3.20 Pipework: Pipework should be sized to ensure optimum performance of the

system.

3.21 Direction of flow: See Fig. 6 (vertical), Fig. 7 (horizontal) 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

Plus Pump.

4.13 Downstream

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

on the Mainsboost Plus Pump, 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. 8).

5 CONFIGURATION

5.11 Mainsboost Plus 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 Plus 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 vessel/

pump 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 9).

Where height restrictions exist

the MPB 200SH and

MBP 250SH litre Mainsboost

Plus can be supplied for

horizontal installation.

5.13 Multiple occupancy application:

Often affected by poor water

supplies Mainsboost Plus

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 and pump located

within the property, sized to

meet the apartments own

demand (see Fig. 10).
