1 READ BEFORE COMMENCING PUMP INSTALLATION

A. Water storage capacity.

1.11 The stored water storage capacity to be pumped, must be sufficient to meet

the flow rates required by the pumped equipment and any other water using

fittings and appliances, which may be operated simultaneously.

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

damage to the shaft seal will result otherwise. See Section 5 - Commissioning.

B. Water temperature

The water entering the pump must be controlled as follows:

1.13 The maximum allowable water temperature is 65 oC.

1.14 The minimum allowable water temperature is 4 oC.

1.15 DO NOT fit a pump if the hot water is heated via a method whereby the water

temperature cannot be controlled, such as solar or solid fuel you must consult

the PumpAssist team on +44 (0) 844 98 000 97.

C. Water flow

1.16 For this pump to operate correctly there must be a minimum gravity flow of at

least 1 l/min through all outlets to be pumped.

D. Pipework - General

1.17 Secure pipework: Ensure pipework to and from pump is independently

supported & clipped to prevent forces being transferred to inlet and outlet

branches of pump.

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

installation (flux damage will void any warranty).

1.19 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.

1.20 DO NOT introduce solder flux to flexible hoses, pumps or pump parts

manufactured from plastic.

1.21 DO NOT allow contact with oil or cellulose based paints, paint thinners or

strippers, acid based descalents or aggressive cleaning agents.

1.22 DO NOT install a non-return valve, or devices which contain non-return

valves, in the suction (inlet) pipework to the pump. The pump must be

free to vent to the supply tank at all times.

1.23 DO NOT bend the flexible hoses beyond 30o. They must be installed as

straight as possible.

1.24 DO NOT connect this pump to the mains water supply.

E. Plumbing & Electrical Installation Regulations

1.25 The plumbing installation must comply with “The Water Supply (Water Fittings)

Regulations 1999” and “BS 6700” building regulations.

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

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

national electrical regulations.

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

2 LOCATION - GENERAL

2.11 Access: For emergencies and maintenance the pump must be

easily accessible.

2.12 Protection: The pump must be located in a dry position, frost free

and protected from freezing, particularly when installed in a loft (not

recommended).

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

the pump from other appliances that generate heat. An 80 mm (3 “)

air gap must be maintained around the pump.

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

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

touched during operation.

2.15 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.

2.16 Static inlet pressure: Before deciding where to locate the unit check to ensure

the static inlet head between pump and cold water level (Figs. 2 & 3) is at least

1 metre and does not exceed the max inlet head of 14 metres for the S1.4.

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

maximum ambient temperature does not exceed 40 oC.

2.18 Pipework: For optimum performance pipework use 28 mm dia., 22 mm can be

used but will result in reduced pump performance.

Pipework should only reduce to 15 mm when entering terminal fitting.

2.19 Static outlet pressure: The static outlet head (Figs. 2 & 3) must also be within

the maximum requirement of 14 metres for S1.4.

2.20 Noise: The anti-vibration mounting feet and flexible hoses which are supplied

as standard, and a precaution to reduce noise transmission, however care must

be taken when mounting the pump that any noise is not amplified through loose

panels or pipework. Do not screw down the pump.

2.21 Direction of flow: Ensure the water flow is in the direction of the arrow marked

on the flow switch reed clamp (vertically upwards).

2.22 Flexible hoses: Use only Stuart Turner supplied hoses.

2.23 Isolating valves: Separate isolating valves (non restrictive) must be fitted to

allow easy pump service.

2.24 Preferred pump location: The pump must, for optimum performance, be sited

as close as possible to and never more than 4 metres from the HOT WATER

cylinder. The pump should always be sited BELOW the HOT WATER take-off

from the cylinder. The pump location is also dependent on limitations of

the static inlet and outlet heads of the installation. For guidance on limitations

and recommended location, consult the following relevant section for hot or cold

water installation.

2 LOCATION - BLENDED WATER INSTALLATION

2 LOCATION - COLD WATER INSTALLATION

2.25 The cold water supply: The supply must be AIR FREE and have a

DEDICATED CONNECTION to the tank which should be via a tank connector,

positioned at a slightly lower level (25 mm minimum) than the feed pipe to the

hot water cylinder.

Do not connect to the mains.

Outlet head must be

below bottom of cold

water tank and able

to pass a minimum of

1 l/min of gravity flow

2.27 Non-Preferred Pump Location: The pump must be located with at least

1 metre flooded suction at all times.

If it is not possible to locate the pump in the preferred area due to site limitations

and it is necessary to position the unit in the loft, or in a position above the

secondary tapping that feeds the pump, then there is an increased risk of air

locks. This risk must be eliminated.

The following method will help to overcome the problem:

In this application only use an Essex or Techflow side entry flange, then fit a “U”

bend or downward loop in the supply pipe to the pump of 350 mm depth

before rising to the pump should ensure the cylinder vents its air up the

expansion pipe, not up the pump feed (Fig. 6).

3 PUMP CONNECTIONS

3.11 Hose to pump: These pumps have G 1 threaded connections to accept the

hoses supplied. The hose end is made water tight with a sealing washer on

assembly, nip tight to 4/5 Nm for water tight seal (Do not overtighten).

3.12 Hose to pipework: Hoses terminating in G 1 threaded connections are

supplied and when securing the male end to a suitable pipe fitting, seal with

PTFE tape or other suitable sealant.
