CE compliant product
PRODUCT DESCRIPTION
Electric motor driven single or twin ended peripheral pump, complete with an automatic
control system, consisting of flow switches and electronic controls.
APPLICATION
Monsoon Standard pumps are suitable for positive head installation conditions. The
pumps are designed for pressure boosting applications in vented stored hot or cold, clean
fresh water systems, where under gravity, some flow (approx. 0.6 l/min) is available. Inlet
pressures to the pump and ambient temperatures must not exceed the values given in the
technical specifications.
Monsoon Standard Single pumps are not suitable for boosting a single side of a dual flow
mixer valve or tap. Consult Stuart Turner for alternative pump.
This pump set must not be used for any other
application without the written consent of Stuart
Turner Limited and in particular, must not be
connected directly to the mains water supply.
This appliance can be used by children aged from
8 years and above and persons with reduced
physical, sensory or mental capabilities or lack
of experience and knowledge if they have been
given supervision or instruction concerning use of
the appliance in a safe way and understand the
hazards involved. Children shall not play with the
appliance. Cleaning and user maintenance shall not
be made by children without supervision.
Children should be supervised to ensure that they do
not play with the appliance.
Please read installation details carefully as they are intended to ensure this product
provides long, trouble free service. Failure to install the unit in accordance with the
installation instructions will lead to invalidation of the warranty.
STORAGE
If this product is not to be installed immediately on receipt, ensure that it is stored in a dry,
frost and vibration free location in its original packaging.

1 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:
o
o
C.
C.
1.13 The maximum allowable water temperature is 65
1.14 The minimum allowable water temperature is 4
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
PumpAssist team on 0844 98 000 97.
C. Minimum Flow
1.16 For this pump to operate correctly there must be a minimum gravity flow of at
least 0.6 l/min through all outlets 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 90
o
bends.
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.
o
1.23 DO NOT bend the flexible hoses beyond 30
. They must be installed as
straight as possible.
1.24 DO NOT connect this pump to the mains water supply.
E. Plumbing & Electrical Installation Regulations
1.25 The plumbing installation must comply with “The Water Supply (Water Fittings)
Regulations 1999” and “BS 6700” building regulations.
1.26 The plumbing installation must be installed by a qualified person.
1.27 The electrical installation must be carried out in accordance with the current
national electrical regulations.
1.28 The electrical installation must be installed by a qualified person.

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 cold water level (Figs. 4 or 5) is at least
0.5 metres and does not exceed the max inlet head of 14 metres.
2.17 Pump position: The pump must be positioned on its anti-vibration mounting feet
and as close to the water source as possible.
2.18 Ambient temperature: The pump must be sited in a location where the maximum
ambient temperature does not exceed 40
2.19 Pipework: For optimum performance pipework MUST be 22 mm.
Pipework should only reduce to 15 mm when entering terminal fitting.
2.20 Static outlet pressure: The static outlet head (Figs. 4 or 5) must also be within
the maximum requirement of 14 metres.
2.21 Noise: The anti-vibration mounting feet and flexible hoses which are supplied
as standard, and a precaution 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.
2.22 Direction of flow: Ensure the water flow is in the direction of the arrow marked
on the flow switch reed clamp (vertically upwards).
2.23 Flexible hoses: Use only Stuart Turner supplied hoses.
2.24 Isolating valves: Separate isolating valves (non restrictive) must be fitted to
allow easy pump service.
2.25 Preferred pump location: The preferred pump location is at floor level next to
the water source or a level that is below the secondary tapping that feeds
the pump. 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.

2.26 Non-Preferred Pump Location: The pump must be located with at least
0.5 metres flooded suction at all times.
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 method will help to overcome the problem:
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. 2 for Twins and Fig. 3 for Singles).

Cold water connection:
2.27 The cold water supply: Must be a DEDICATED AIR FREE supply via a tank
connector , and must be positioned at a slightly lower level (25 mm minimum) than
the feed pipe to the hot water cylinder.
Do not connect to the mains.
2.28 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.

2. 29 Hot water cylinder or storage tank: 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 for all models except the
S4.5 bar twin which should be a minimum of 28 mm.
2.30 Hot water supply: The pump must be supplied with a dedicated feed direct
from the hot water cylinder or storage tank, ensuring an air free connection to the
cylinder, which can be made by one of the methods shown in Fig. 6 .
