1 IMPORTANT FACTS: READ BEFORE COMMENCING PUMP INSTALLATION
A Water storage capacity.
1.11 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.
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 TechAssist team on [phone].
C Minimum Flow
1.16 For this pump to operate correctly there must be a minimum gravity flow of at
least 0.8 l/min through the outlet 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.

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 the bottom of the cold water
tank (Figs. 5 & 6) is at least 0.5 metres and does not exceed the max inlet
head of 10 metres.
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 MUST be 22 mm.
Pipework should only reduce to 15 mm when entering terminal fitting.
15 mm pipework can be used but may reduce performance at the terminal
fitting.
2.19 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.
2.20 Direction of flow: Ensure the water inlet supply is
connected to the correct pump ports Fig. 2.
2.21 Flexible hoses: Only use the Stuart Turner hose set supplied with the pump.
2.22 Isolating valves: Separate system isolating valves (non restrictive) must be
fitted to allow easy pump service.
Fig. 2

Cont ...
2.23 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.
2.24 Non-Preferred Pump Location: The pump must be located with at least
0.5 metre flooded suction at all times.
If it is necessary to position the Pump above the secondary tapping on the
hot cylinder it is fed by, the risk of introducing air will be increased.
To avoid this risk one of the two following solutions must be adopted:
The use of a Top Entry cylinder flange.
The use of a Stuart Side Entry (SE) cylinder flange, which should have the
addition of an inverted loop (“U” bend) of 350 mm minimum drop before
rising to the pump, located as close as possible to the cylinder wall. This will
ensure the pump receives an air free supply and the cylinder vents any air up
the vent pipe and not the pump feed (Figs. 3 & 4).

6 MAINTENANCE
Do not remove the terminal box cover. This is a non serviceable
pump.
6.11 Water scale: As water is heated scale deposits are released in areas of hard
water, scale can cause the mechanical seal to stick if left without use for long
periods. The pump must be run for at least 5 minutes every four weeks to
“exercise” all working parts. Run on cool water. See Section 7 – Technical
Specification for note on water temperature. This particularly applies to guest
bathrooms used infrequently.
6.12 Cleaners, Disinfectants and Descalents:
Acid based descalents and aggressive cleaning agents must not
come into contact with the pump. The pump must be removed
from the system prior to the use of these products. The system
should be flushed to remove all chemicals before the pump is re-
connected.
If in any doubt as to the suitability of the chemical solutions, please
contact our TechAssist helpline on [phone].

5 COMMISSIONING
5.11 System Flushing: This pump incorporates push-in connectors
and plastic components that must not come into contact with
solder flux, acid-based descalents or aggressive cleaning agents.
The pipework system should be flushed out prior to the pump
being connected to ensure any contaminants/chemical residues
and foreign bodies are removed from elsewhere in the system.
5.12 Water Supply: Always ensure that water storage capacity is adequate to meet
the demand. Ensure the pump chamber is full of water before starting the
pump.Failure to do this could result in seal damage. To ensure dry running
does not occur the pump must be primed as described in priming section
below. Do not run pump dry.
5.13 Priming: The pump must be primed (filled with water) before starting. Turn
on water supply from the system service valves, prime and vent the pump by
opening the pump inlet and outlet isolating valves to allow pump to fill and
vent. In the case of twin pumps, both pump chambers must be
independently primed.
5.14 Starting:
a) Ensure all outlets are closed, turn power supply ‘on’.
b) Open and close the pumped outlet allowing water to flow until all air is
purged. As the outlet is opened and closed, the pump will start and stop
respectively.
c) When opened and closed the pumped outlet will now turn the pump
on/off. If this is confirmed to be the case, the system is now operating
correctly.
d) Carefully check pump and pipework for leaks whilst pump running and
stationary before leaving the installation unattended.

3.13 Typical Low Level Installation:
In certain installations it may be necessary to install a 90° bend on the inlet or
outlet connections of the pump before the flexible hose to accommodate a
low level installation.
Below are some preferred connection options. All connections seal on the
pump body using a fibre or rubber sealing washer. Tap connector fittings
should be used which must be of an appropriate pressure and temperature
rating.
It is essential when using any of the fittings shown below, that a correct water
tight seal is obtained between the pump body and selected fitting and also
the flexible hose and selected fitting. If in doubt contact the fitting
manufacturer and confirm compatibility with the connection to be sealed.
Under no circumstances swap the inlet and outlet hoses to achieve a low level
installation.
Carefully check connections and pipework for leaks whilst pump running and
stationary before leaving the installation unattended.

5 COMMISSIONING
5.11 System Flushing: This pump incorporates push-in connectors
and plastic components that must not come into contact with
solder flux, acid-based descalents or aggressive cleaning agents.
The pipework system should be flushed out prior to the pump
being connected to ensure any contaminants/chemical residues
and foreign bodies are removed from elsewhere in the system.
5.12 Water Supply: Always ensure that water storage capacity is adequate to meet
the demand. Ensure the pump chamber is full of water before starting the
pump.Failure to do this could result in seal damage. To ensure dry running
does not occur the pump must be primed as described in priming section
below. Do not run pump dry.
5.13 Priming: The pump must be primed (filled with water) before starting. Turn
on water supply from the system service valves, prime and vent the pump by
opening the pump inlet and outlet isolating valves to allow pump to fill and
vent. In the case of twin pumps, both pump chambers must be
independently primed.
5.14 Starting:
a) Ensure all outlets are closed, turn power supply ‘on’.
b) Open and close the pumped outlet allowing water to flow until all air is
purged. As the outlet is opened and closed, the pump will start and stop
respectively.
c) When opened and closed the pumped outlet will now turn the pump
on/off. If this is confirmed to be the case, the system is now operating
correctly.
d) Carefully check pump and pipework for leaks whilst pump running and
stationary before leaving the installation unattended.

2.23 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.
2.24 Non-Preferred Pump Location: The pump must be located with at least
0.5 metre flooded suction at all times.
If it is necessary to position the Pump above the secondary tapping on the
hot cylinder it is fed by, the risk of introducing air will be increased.
To avoid this risk one of the two following solutions must be adopted:
The use of a Top Entry cylinder flange.
The use of a Stuart Side Entry (SE) cylinder flange, which should have the
addition of an inverted loop (“U” bend) of 350 mm minimum drop before
rising to the pump, located as close as possible to the cylinder wall. This will
ensure the pump receives an air free supply and the cylinder vents any air up
the vent pipe and not the pump feed (Figs. 3 & 4).

6 MAINTENANCE
Do not remove the terminal box cover. This is a non serviceable
pump.
6.11 Water scale: As water is heated scale deposits are released in areas of hard
water, scale can cause the mechanical seal to stick if left without use for long
periods. The pump must be run for at least 5 minutes every four weeks to
“exercise” all working parts. Run on cool water. See Section 7 – Technical
Specification for note on water temperature. This particularly applies to guest
bathrooms used infrequently.
6.12 Cleaners, Disinfectants and Descalents:
Acid based descalents and aggressive cleaning agents must not
come into contact with the pump. The pump must be removed
from the system prior to the use of these products. The system
should be flushed to remove all chemicals before the pump is re-
connected.
If in any doubt as to the suitability of the chemical solutions, please
contact our TechAssist helpline on [phone].
