STEP 1 PUMP LOCATION (General)
WARNINGS:
The pump must not be located where the static inlet pressure to the
pump is greater than permitted.
Pump Location
If possible 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.
Care should be taken to protect pump from frost and freezing,
particularly when located in loft position.
The motor casing can become very hot under normal operating
conditions, care should be taken to ensure it cannot be touched
during operation.
The pump must be installed so that the following conditions are met:
Locate the pump in a dry, frost free position where it cannot be sprayed with water. It
should be positioned horizontally on its anti-vibration mounting feet and should not be
screwed down. It should be positioned as close to the water source as possible, having a
minimum flooded suction head of 0.5 metres at all times.
Ensure the water flow is in the direction of the arrow that is marked on the flow switch
module casing (vertically upwards).
For the pump to function correctly, it must be installed in a positive head position, a
gravity flow of approx. 0.8 litres per minute is required from the highest outlet to operate
the built-in flow switch. This is normally achieved with a static head of 100 mm from base
of header tank to highest position of the shower terminal fitting.
Before deciding where to position the unit, check to ensure the static inlet head of water
above the pump does not exceed the values given in Figs. 5, 6, 7 or 8.
Typical pump locations are in an airing cupboard, or inside a vanity unit with a small
purpose built dry and ventilated enclosure. The enclosure should have a minimum
clearance of 80 mm (3 ") between the pump and housing on all sides. The enclosure
should be secure and access should only be available by the use of tools.
The resilient anti-vibration mounting feet and flexible hoses which are supplied as
standard, are a precaution to reduce noise transmission, however care must be taken
when mounting the pump that any noise is not amplified through loose panels, pipework
or other mounting medium.
The preferred pump location is at floor level next to the hot water cylinder or a level that
is below the secondary tapping that feeds the pump. This will ensure the pump has
access to an air free water supply which is important for trouble free operation (Fig. 5 for
Twins and Fig. 6 for Singles).
Cont....

- 4 -
Least Preferred Pump Location (shaded area). Pump located above the hot cylinder
can increase the risk of air locks.
Note: If installed in loft there must be a height of 200 mm from water surface to
highest point of hot or cold inlet or outlet pipework at all times to prevent air locking.
Preferred Pump Location (shaded area). Pump at a level below draw
off tapping in cylinder.
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 measures are suggestions that may overcome the problem:
1) 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. 7 for Twins and Fig. 8 for Singles).
2) An alternative to the above would be the installation of an automatic air vent situated
at the top of a vertical pipe run, directly connected to the pump discharge. This will
ensure any air collecting in the pump is automatically vented.

STEP 2: PIPEWORK (General)
WARNINGS:
Ensure pipework to and from pump is independently supported to
prevent forces being transferred to inlet and outlet branches of pump.
Do not introduce solder flux to pumps or pump parts manufactured
from plastic. All solder joints should be completed and flux residues
removed prior to pump connection.
Do not allow contact with oil or cellulose based paints, paint thinners
or strippers, acid based descalents or aggressive cleaning agents.
Do not allow scale or debris to enter pump. Fit inline strainers to
eliminate the problem in systems at risk.
Always install isolating valves to both suction and delivery pipework.
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
tanks at all times.
It must be ensured that the water storage capacity is sufficient to meet the flow rates
required by the pump and any other water using fittings and appliances, which may be
operated simultaneously.
As a rule of thumb: assuming a cold water temperature of 10°C and a hot water
temperature of 65°C.
A 6-minute shower using 10 litres/min will consume 40 litres of hot water and 20 litres
of cold. This means the total quantity of water used from the cold water storage tank
will be 60 litres (40 + 20).
A 10-minute shower using 15 litres/min will consume 100 litres of hot water and 50
litres of cold. This means the total quantity of water used from the cold water storage
tank will be 150 litres (100 + 50).
The pipework feeds to the storage tank should be of adequate size to ensure
replenishment rate of tank is sufficient to meet the needs of the pump.
Care should be taken in the design of pipework runs, to minimize the risk of air locks.
The pump (or pumps) should be supplied with balanced pressure hot and cold
supplies.
To prevent loss of water pressure through pipework use 22 mm pipework throughout.
Any bend requirements should be achieved by hand drawing the tube or by the use of the
appropriate bend fittings. All pipework should be securely clipped.
Isolating valves (not supplied) should be fitted in the suction and delivery pipework to
enable easy isolation and access to the pump.
When pump is to be installed in areas where there is a risk of debris or scale build up
within the system, it is recommended that both hot and cold inlets are fitted with inline
strainers, (these are not supplied with the kit).

Pipework Connections (Cold)
The pump must be supplied with a dedicated feed direct from the cold water
storage tank.
The supply must be air free and connection of the feed pipe to the tank should be via a
tank connector, positioned at a slightly lower level (25 mm minimum) than the feed pipe to
the hot water cylinder.
Pipework Connections (Hot)
When a hot water cylinder or storage tank is used, ensure the pipework size from the
cold water storage to the hot water storage is of adequate size and a minimum of 22 mm.
The pump must be supplied with a dedicated feed direct from the hot water
cylinder or storage tank.
The supply must be air free and connection to the cylinder can be made by one of the
methods shown in Fig. 9.
When the method of connection is to be made via the expansion pipe, the cold water
storage cistern should be at least 1 metre above the top of the hot water cylinder.
Pipework Connections (Connection between pump and system outlet)
This should run as far as possible in 22 mm copper tube. Pipework should only be
reduced to 15 mm copper at pump and if necessary when entering the terminal fittings.
By this method the maximum performance of the pump will be maintained.
STEP 3 PUMP CONNECTIONS (Release and connection of push-in connectors)
WARNINGS:
Do not use stainless steel, chrome or nickel plated pipe with Stuart
Turner push-in plumbing connections.
Do not introduce solder flux into the joint or surrounding area, as
plastics will be attacked and may fail.
All solder joints should be completed before final connection to push-
in connections, either on the flexible hose or the pump head. Flux
residues must be removed.

The hose connection nuts on the inlet and outlet of the pump should
not be removed.
1. Stuart Turner recommend only the use of their 15 mm flexible hoses.
The hose and pump are fitted with plastic push-in connectors, which must only be
connected with the following:
a) 15 mm diameter copper pipe to BS EN 1057 - R250 (half hard) - Table 3.
b) 15 mm plastic pipe to BS 7291 part 1 and part 2 (Table 1), or part 3 (Table 1)
plus internal support sleeve*.
* The internal bore of the plastic pipe must be supported against collapse with the
pipe manufacturers recommended support sleeve (pipe insert).
c) Appropriate plumbing fittings from the John Guest 'speedfit' push-in plumbing
fitting range.
Other manufacturers fittings are not necessarily compatible and may not provide a
water tight connection.
Ensure the pipe is free from all score marks and deformities in the area of the
insertion depth (Fig. 10) and cut the pipe square removing all burrs and sharp edges
to prevent damage to the sealing 'O'-ring.
2. Prior to inserting pipe into fitting, mark the insert depth on the wall of the pipe with a
soft pencil at a distance of 30 mm from the end to be inserted (Fig. 10).

3. Check in the mouth of the fitting that the ‘O’-ring, nylon washer and collet are in
position as shown in Fig. 11.
4. Push the pipe firmly into the fitting, until pencil mark is level with the top of the collet
and the pipe stop resistance is felt. Pull on the pipe to check it is secure and
correctly fitted.
5. To release the joint, push pipe firmly into the fitting, hold the collet down and gently
remove pipe. If the system has been filled with water care should be taken to isolate
the pump and towels used to absorb spilled water.
If you have any concern either about using push-in fittings or should the joint leak on
final test, isolate the water supplies and contact the Service Department on 01491

STEP 4 ELECTRICAL INSTALLATION
The electrical installation must be carried out in accordance with the
current national electrical regulations and installed by a competent
person.
In the interests of electrical safety a 30 mA residual current device
(R.C.D.) should be installed in the supply circuit. This may be part of
a consumer unit or a separate unit.
Before starting work on the electrical installation ensure the power
supply is isolated.
This applicance must be earthed.
The motor and wiring must not be exposed to water.
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.
The motor fitted to this pump is suitable for a 230/1/50Hz supply. It is thermally
protected by an integral auto resetting thermotrip for your safety and rated for the duty
listed in the technical specification section.
Electrical Connection
The motor is provided with a factory fitted supply cord. This must be permanently
connected to the fixed wiring of the mains supply. Means for disconnection must be
incorporated in the fixed wiring in accordance with the wiring rules.
A suitable method of connection would be via a double pole switched, fused connection
unit complying with BS 1363-4, protected with a 5 Amp fuse.
The connection unit should be mounted in an easily accessible position and should be
labelled if confusion is possible, to allow easy identification of the pump isolating switch.
Earthing
This appliance must be earthed via the supply cord, which must be correctly connected
to the earth point located in the terminal box.
Copper or metallic pipework must have supplementary earth bonding where the
continuity has been broken by flexible hoses or plastic components. Adjacent suction and
delivery pipes should be fitted with earthing clamps to BS 951 and connected with
earthing wire size 4 mm² (Fig. 14). A standard kit is available from Stuart Turner (Part No.
17044).
Certain installations may require additional earthing arrangements such as equipotential
bonding. Reference should be made to the relevant regulations concerning this subject to
ensure compliance.

Note: Cable diameter range:- 6.5 mm to 9.5 mm.

Supply Cord Extension
The pumps are fitted with a supply cord to the following specification:-
HO5VV-F3 G 0.75 mm² - 6 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.
STEP 5 COMMISSIONING
WARNINGS:
The motor casing can become very hot under normal operating
conditions, care should be taken to ensure it cannot be touched
during operation.
Do not run pump without guards and terminal box lid correctly fitted.
The pump chamber must be full of water at all times. Seal damage will
result if the pump runs dry.
1. 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.
2. 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. Do not run pump dry.
3. Priming
The pump must be primed (filled with water) before starting. Turn on water supply,
prime and vent the pump by opening the outlet valve to allow pump to fill and vent.
In the case of twin pumps, both pump chambers must be independently primed.
4. Pre-Start Check
Always ensure the pump is in a positive head position with flooded suction. A gravity
flow of approx. 0.8 litres/min from the highest outlet is required to operate the integral
flow switch.
5. Starting
a) Switch on power and open terminal fitting. Pump should start and stop upon
demand.
b) Open and close all outlets in turn associated with the pump, allowing water to
flow from each outlet until all air is purged. As each outlet is opened and closed,
the pump will start and stop respectively.
- 13 -
Cont....

- 14 -
c) Any tap or control valve within the system when opened and closed will now turn
the pump on/off. Check system for leaks, if clear the system is now operating
correctly.
d) Carefully check pump and pipework for leaks whilst pump running and stationary
before leaving the installation unattended.
For Further Technical Support
Phone the Stuart Turner support line on 01491 572655. Our staff are trained to help
and advise you over the phone or arrange for a service engineer to call.
MAINTENANCE
WARNINGS:
Care should be taken to protect pump from frost and freezing,
particularly when located in loft position.
Pump Location
If possible 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.
1. No routine maintenance is required, but provision should be made
for easy access to the pump to allow repairs due to normal wear and
tear.
2. Disconnect electrical supply before working on pump.
3. Turn off water supplies to the pump and release pressure by opening water outlets
before attempting maintenance.
4. When the installation is fitted with inline strainers (not supplied with kit), these may
require periodical cleaning. The frequency of this operation is dependent upon
installation conditions.
The strainer is located in the inlet pipework to the pump (see pump connection
section). The gauze filter is removed as follows:-
a) Isolate pump electrically.
b) Release all system pressure.
c) Isolate water supply.
d) Remove screwed hexagonal plug from strainer body (see pump connection
section).
e) Remove and clean stainless steel gauze filter.
f) Re-assemble gauze and secure plug tightly.
g) After maintenance is completed, refer to commissioning section for instructions
on re-starting pump.
5. As water is heated scale deposits are released in areas of hard water (usually south
of a line between the Wash and Bristol Channel), scale can cause the mechanical
seal to stick if left without use for long periods. We recommend the pump is run for at
least 5 minutes every four weeks to “exercise” all working parts. Run on cool water.
See technical specification for note on water temperature. This particularly applies to
guest bathrooms used infrequently.
Cont....

- 15 -
Cleaners, Disinfectants and Descalents
On installations where chemical disinfectants or descalents are periodically
used, the compatibility of the chemical solution regarding the pump must be
considered.
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 refer to Stuart
Turner Ltd.

TECHNICAL SPECIFICATION
Stuart Turner reserve the right to amend the specification in line with its policy of
continuous development of its products.
Note: For information on other voltages/frequencies which are not shown, consult any
supplementary instruction sheet supplied, or the rating label attached to the
pump.
Maximum permissable water temperature 65°C.
*Note: Max working pressure is the maximum pressure that can be applied to the
pump internal casing under any installation conditions.
**Note: In normal circumstances the temperature of stored water should never exceed
65°C. A stored water temperature of 60°C is considered sufficient to meet all
normal requirements and will minimize deposition of scale in hard water areas.
