STEP 1 PUMP LOCATION
WARNINGS:


The pump must not be located where the static inlet pressure to the
pump is greater than 14 metres (1.4 bar).
Care should be taken to protect pump from frost and freezing,
particularly when located in a loft installation.



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.
The motor casing can become 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
reed clamp (vertically upwards).
For the pump to function correctly, it must be installed in a positive head position, a
gravity flow of approx. 0.6 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. 3, 4, 5 or 6.
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. 3 for Twins
and Fig. 4 for Singles).
Either end of a twin pump is suitable for hot or cold water.

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. 5 for Twins and Fig. 6 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.
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.
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, pump parts or hoses
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.
Never operate pump with inlet and/or outlet isolating valves in the
closed position. Damage will occur!
Cont ...
-4-

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 twin pump (or two single pumps) must 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.
The flexible hoses supplied incorporate integral isolating valves. These hoses should
be fitted in the suction and delivery pipework to enable easy access to the pump when
required.
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)
(Applicable to S1.5, S2.0, S3.0 and S4.0 bar Twins, S2.0, S3.0 and S4.5 bar Singles)
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. 7.
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.

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.
Carefully check connections and pipework for leaks whilst pump running and stationary
before leaving the installation unattended.

STEP 5 COMMISSIONING
WARNINGS:



The motor casing can become 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.
- 13 -
3. Priming
WARNING
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. 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.
4. Pre-Start Check
Always ensure the pump is in a positive head position with flooded suction. A gravity
flow of approx. 0.6 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.
c) Any tap or control valve within the system when opened and closed 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.

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 a loft installation.
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. The inlet strainers may require periodical cleaning. The frequency of this operation is
dependent upon installation conditions.
The strainer is located in the inlet assembly of the pump casing (see pump
connection section) and is removed as follows:a) Isolate pump electrically.
b) Release all system pressure.
c) Isolate hot and cold water supplies via the integral pump isolating valve located in
the flexible hoses and release hose nuts connected to the pump (see pump
connections section).
d) Remove M4 screws (2 off) from inlet assembly, lift brass inlet fitting (with ‘O’-ring)
and clamp away from pump casing (Fig. 18).
e) Remove strainer with long nose pliers noting location lug position upon removal
(Fig. 18) and clean thoroughly.
f) Refit strainer taking care to position lug in body inlet port location slot (Fig. 18)
and re-assemble pipework. Tighten M4 clamp screws to 1.5 Nm torque.

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.
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

TROUBLE SHOOTING GUIDE
Symptoms
Probable Cause
Recommended Action
Pump will not start.
Electrical supply.
Check wiring connections.
Check all switches are ‘on’.
Check fuse (see fuse section).
Check circuit breaker is set.
Faulty reed switch/PCB.
Refer to circuit test as detailed in Fig. 19.
Insufficient gravity flow.
Check that the gravity flow of water is available to the fittings
of approx. 0.6 l/min.
Motor thermotrip activated.
Wait for thermotrip to auto-reset and check that duty point and
run time is within specification (see technical specification).
Water supply.
If no... check water in the supply tank and all stopcocks and
isolating valves are open.
Strainers blocked.
Remove and clean inlet strainers (see maintenance section).
Air locked water feed.
Vent hot water pump of air.
Check cold feed to hot water cylinder.
Check water level in cold water tank and that all stopcocks
and isolating valves are open.
Boiler is switched off.
Check boiler is switched ‘on’.
Check cylinder thermostat.
Check immersion heater.
Check cylinder contains hot water.
All hot water has been used.
Check tank volume is adequate.
Faulty thermostatic mixer valve.
Consult makers instructions.
Pump starts when outlets are off.
Leak in system.
Check tap washers, w/c valve washers, pipe joints.
Pump runs on when all terminal
outlets are closed.
Leak in system.
Check tap washers, w/c valve washers, pipe joints.
Reed clamp out of position.
Ensure reed clamp is fitted correctly in location groove
(Fig. 19).
Faulty reed switch or P.C.B.
If pump continues to run, this indicates a closed circuit in
either the flow switch reed or P.C.B. in the terminal box, these
should be checked electrically.
Jammed flow switch.
Isolate the pump electrically and hydraulically and remove
brass housing that contains float. Check for free movement.
Blocked inlet strainers.
Clean inlet strainers (see maintenance section).
Blocked shower head spray
plate.
Clean in accordance with manufacturers instructions.
Blocked pipework or pump.
Isolate pump electrically and hydraulically, locate blockage
and remove.
No hot water.
Reduced flow/performance.

Flow Switch Circuit Test
1. First confirm visually that the flow switch reed clamps have not been dislodged during
handling or installation. The clamps must be fully located within their flow switch
body groove as shown.
2. To carry out the following test you will need to obtain a magnet, a typical fridge
magnet is suitable.
3. Ensure the power supply is switched on.
4. Position the magnet directly in front of the reed clamp as shown. If pump does not
start, then slowly move the magnet up and down to a position that exceeds the extent
of the reed clamp. The pump should instantaneously start at some point during this
extent of movement. If this does not happen, this indicates a possible fault with the
reed switch or the P.C.B which is located within the terminal box. These should be
checked electrically. Consult Stuart Turner for further instructions.

GOOD PRACTICE
Always flush system prior to installing a new or serviced pump.
Always ensure both sides of the pump (if applicable) are primed (filled with water)
before starting the pump. DO NOT RUN PUMP DRY.
Always ensure the pump is in a positive head position with flooded suction.
Always ensure anti-vibration feet are used.
Ensure pump is sited in dry ventilated position.
Do not allow pump to freeze.
Abide by the Water Supply (Water Fittings) Regulations 1999.
Always ensure pump isolating valves in the inlet and outlet flexible hoses are in the fully
open position.
Ensure earth continuity between suction and delivery pipes.
Always ensure pump wiring conforms with the current national electrical regulations and
installed by a competent person.
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.
Carefully check pump and pipework for leaks before leaving the installation unattended.
