1 IMPORTANT FACTS: READ BEFORE COMMENCING PUMP INSTALLATION
A. Water storage capacity.
1.11 The 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. DO NOT RUN PUMP DRY.
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 4 - 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 Ambient temperature: The pump must be sited in a location where the
maximum ambient temperature should not exceed 40 oC continuous or 50 oC
intermittent.
1.16 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 [phone].
C. Pipework - general
1.17 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.
1.18 DO NOT allow contact with oil or cellulose based paints, paint thinners or
strippers, acid based descalents or aggressive cleaning agents.
D. Plumbing installation regulations
1.19 The plumbing installation must be installed by a qualified person and in
accordance with local regulations.
E. Electrical/installation regulations
1.20 The electrical installation must be installed by a qualified person and in
accordance with local regulations.
1.21 Check the mains voltage and frequency corresponds to the values on the pump
rating plate.

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.
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 Pump position: The pump must be positioned on its mounting feet and as
close to the water source as possible.
2.17 Mounting foot securing: This pump is fitted with cast feet. If there is a
requirement to secure the pump via the feet, the following points should be
noted.
The pump should be mounted only in the horizontal position.
The mounting bolts used to secure the pump must be fitted with a plain washer
to distribute clamping load evenly across load bearing face of foot (not supplied).

3 ELECTRICAL INSTALLATION / EARTHING
3.11 Regulations: The electrical installation must be carried out in
accordance with the current local regulations by a qualified person.
3.12 Safety: In the interests of electrical safety a 30 mA residual current
device (R.C.D. not supplied) should be installed in the supply circuit.
This may be part of a consumer unit or a separate unit.
3.13 Before starting work on the electrical supply ensure power supply is
isolated.
3.14 DO NOT allow the supply cord to contact hot surfaces, including the
motor shell, pump body or pipework. The cord should be safely routed
and secured by cable clips.
3.15 Earthing: This appliance must be earthed via the supply cord, which must be
correctly connected to the earth point located in the terminal box.
3.16 Connections: The pump must be permanently connected to the fixed wiring of
the mains supply using the factory fitted supply cord, via a dedicated double
pole switched fused spur off the ring main.
3.17 Wiring of connection unit:
WARNING: This appliance must be earthed.
The wires in the mains lead are coloured in accordance with the following code:
Green and Yellow: Earth Blue: Neutral Brown: Live
As the colours of the wires in the mains lead of this appliance may not
correspond with the coloured markings identifying the terminals in your
connection unit proceed as follows:
Green and yellow coloured wire must be connected to the terminal in the
connection unit marked with the letter E or by the earth symbol: or coloured
green or green and yellow.
Blue coloured wired must be connected to the terminal marked with the letter N
or coloured black.
Brown coloured wire must be connected to the terminal marked with the letter L
or coloured red.

3.19 Fuse: All models should use 13 Amp fuse.
3.20 Supply cord replacement:
The internal wiring within the terminal box is routed and
secured to ensure compliance with the electrical standard
EN 60335-1. It is essential that prior to any disturbance of
this internal wiring, all cable routing and securing details are
carefully noted to ensure re-assembly to the same factory
pattern is always maintained.
3.21 If the supply cord is to be changed or damaged, it must be replaced by a special
cord available from Stuart Turner or one of its approved repairers.
3.22 Cable Gland Fitting Instructions:
To enable correct assembly of the cable gland the
‘O’-ring (Fig. 5 item 1) must be placed over the cable
before the clamping insert (Fig. 5 item 2) can be
tightened.
Note: Cable diameter range:- 9.2 mm to 11.9 mm.
3.23 Supply Cord Extension:
The pumps are fitted with a supply cord to the
following specification:-
All models ..............HO7RN-F3 G 1.5 mm² - 10 Amp rated cable.
If the supply cord is to be extended, a cord of the same specification should be
used. Any connections or junction boxes used should be specifically suited for
the application and installed in accordance with the manufacturers instructions.

We recommend the use of a footvalve and strainer when a suction lift is required,
to reduce priming time.
4.14 System flushing: 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.
4.15 Priming:
Never operate pump with inlet and/or outlet isolating valves in
the closed position. Damage will occur!
The pump must be primed (filled with water) before starting.
4.16 Turn on the isolating valves.
(a) Loosen vent plug and allow an even flow of water this may take a
few seconds.
(b) Re-seal vent plug, nipping tight.
The pump is now ready to start.
4 PLUMBING
4.11 Pipework: For optimum performance pipework use 28 mm dia., 22 mm can be
used but will result in reduced pump performance.
4.12 Isolating valves: Separate isolating valves (non restrictive) must be fitted to
allow easy pump service.
4.13 This pump has a self priming ability once filled with water. It can therefore be
used to draw water from a storage tank either above or below the pump position.
(c) Should the pump not build up pressure after running for 2-3 minutes
switch off and repeat priming process.
4.17 Maintenance:
This product is maintenance free for its life, however it is a mechanical product
and will eventually show signs of wear. Spare parts are available, for more
information phone the Stuart Turner PumpAssist team on [phone].

5 TECHNICAL SPECIFICATION
Stuart Turner reserve the right to amend the specification in line with its policy of
continuous development of its products.
*Note: The maximum pressure that can be applied to the pump under any
installation conditions.
**Note: A stored water temperature of 60oC is considered sufficient to meet all
normal requirements and will minimise deposition of scale in hard water
areas.
*** With footvalve fitted.
Although these pumps are self priming we recommend a footvalve/strainer is
used if a suction lift is required.
5.11 Noise: The equivalent continuous A-weighted sound pressure level at a
distance of 1 metre from the pump does not exceed 70 dB(A).
