ability during transit, it must be checked prior to installation and should be hand

tight.

IMPORTANT:

•

DO NOT

overtighten pressure vessel.

•

DO NOT

lift/carry the pump by the transfer pipe or pressure

vessel manifold.

•

DO NOT

remove manifold plug from top of pressure vessel

IMPORTANT FACTS - READ BEFORE COMMENCING PUMP INSTALLATION

5.1 Water Storage Capacity

The hot and cold water storage capacity 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.

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

damage to the shaft seal will result otherwise. See Section 9 - Commissioning.

5.2 Water Temperature

The water entering the pump must be controlled as follows:

•

The maximum allowable water temperature is 65 °C.

•

The minimum allowable water temperature is 4 °C.

•

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 TechAssist team on

+44 (0) 800 31 969 80.

5.3

Pipework

–

General

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

& clipped to prevent forces being transferred to inlet and outlet branches of

pump.

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

installation (flux damage will void any warranty).

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 90° bends.

•

DO NOT

introduce solder flux to flexible hoses, pumps or pump

parts manufactured from plastic.

•

DO NOT

allow contact with oil or cellulose based paints, paint

thinners or strippers, acid based descalents or aggressive

cleaning agents.

•

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.

•

DO NOT

bend the flexible hoses beyond 30°. They must be

installed as straight as possible.

•

DO NOT

connect this pump to the mains water supply.

•

DO NOT

stress the inlets/outlets of the pump from the

misalignment of hoses/pipework.

5.4 Plumbing Installation Regulations

The plumbing installation must comply with the current water and building

regulations.

The plumbing installation must be installed by a qualified person.

5.5 Pressure Vessel

Pressure vessel is charged at the factory see Section 10 - Maintenance for details.

LOCATION

GENERAL

•

Access

: For emergencies and maintenance the pump must be

easily accessible

•

Protection

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

and protected from freezing, particularly when installed in a loft

(not recommended).

•

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.

•

Safety

: The motor casing can become very hot under normal

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

touched during operation.

•

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.

•

Static inlet pressure

: Before deciding where to locate the unit,

check to ensure the static inlet head between pump and the

bottom of the cold water tank (Figure 5 and Figure 6), is at least

0.5 metres and does not exceed the max inlet head of 6 metres.

•

Ambient temperature

: The pump must be sited in a location

where the maximum ambient temperature does not exceed

40 °C.

•

Pipework

: For optimum performance pipework MUST be 22 mm.

Pipework should only reduce to 15 mm when entering terminal

fitting.

•

Static outlet pressure

: The static outlet head must also be within

the maximum requirement (Figure 5 and Figure 6).

•

Noise

: If supplied the anti-vibration mounting feet and flexible

hoses can be used 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.

•

Direction of flow

: Ensure the water flow is in the direction of the

arrow that is marked on the flow switch reed clamp (vertically

upwards).

•

Flexible hoses

: Only use the Stuart Turner hose set supplied with

the pump.

•

Isolating valves

: Separate system isolating valves (non restrictive)

must be fitted to allow easy pump service.

•

Inline strainer:

You

MUST

ensure the inlet pipework is fitted with

an inline strainer.
