1 IMPORTANT FACTS: READ BEFORE COMMENCING PUMP INSTALLATION

A. Water storage capacity.

1.11 The 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 4 - Commissioning.

B. Water temperature

The water entering the pump must be controlled as follows:

1.13 The maximum allowable water temperature is 35 oC.

1.14 The minimum allowable water temperature is 4 oC.

C. Pipework - General

1.15 Secure pipework: Ensure pipework to and from pump is independently
supported & clipped to prevent forces being transferred to inlet and outlet
branches of pump.

1.16 Flux: Solder joints must be completed and flux residues removed prior to pump
installation (flux damage will void any warranty).

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 90o bends.

1.18 DO NOT introduce solder flux to flexible hoses, pumps or pump parts
manufactured from plastic.

1.19 DO NOT allow contact with oil or cellulose based paints, paint thinners or
strippers, acid based descalents or aggressive cleaning agents.

1.20 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. Exceptions can be made in
the case of suction lift installations when a footvalve is required.

1.21 DO NOT connect this pump to the mains water supply.

D. Plumbing Installation Regulations

1.22 The plumbing installation must comply with the current water and building
regulations.

1.23 The plumbing installation must be installed by a qualified person.

1.24 The electrical installation must be carried out in accordance with the current
national electrical regulations.

1.25 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 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 pump check to
ensure the static inlet head (Fig. 2) meets the minimum requirement of 1 metre
and does not exceed the maximum requirement of 5 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 28 mm should be used.
22 mm is acceptable, however, any pipe size reduction will reduce the pumps
performance.

2.19 Do not run against a closed valve for periods longer than 5 minutes.

2.20 Portable: The pump is suitable for use as a portable unit and is provided with
a carrying handle for this purpose.

2.21 Pipe size: To prevent loss of pressure through pipework, use pipe size to match
pump (19 mm internal diameter) whenever possible, minimising 90° bends
(sweeping bends).

2.22 Isolating valves: If permanently installed, isolating valves MUST be fitted in
suction and delivery pipework to enable easy isolation and access to the pump.

2.23 Inline strainer: When pump is to be installed in areas where there is risk of
debris or scale build up within the system, you MUST ensure the inlet pipework
is fitted with an inline strainer.

2.25 Self Priming: Jet 55-45 and 80-45 pumps are capable of self priming the
suction hose assembly, providing a footvalve and strainer (not supplied) is
always used for this type of installation. The Jet pump can be used in a suction
lift installation providing the height of lift is no greater than maximum permitted
(Fig. 3).

2.26 Footvalve/strainer: It is important that the optional footvalve and strainer is
always used for suction lift installations. This pump is capable of a
maximum suction lift of 5 m in this case only, an NRV in the footvalve is
permissible (Fig. 3), Stuart Pt. No 26704.

2.27 Suction pipe: Lay the suction piping over the shortest possible distance and
ensure there is a constant rise from the water source to the pump. Any high
spots will cause air pockets to form reducing system efficiency. The suction
hose must be a minimum of 25 mm to ensure the pump is not starved of water
and must be reinforced to prevent it collapsing.

2.28 Connections: Ensure all joints in suction pipework are completely airtight.
Failure to comply will result in loss of prime.

2.29 Position: The intake of the footvalve/strainer should be positioned so that it
cannot be blocked with debris or silt that are frequently found in the bottom of
sumps and wells.

4 COMMISSIONING

4.11 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.

4.12 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.

4.13 Priming: Prior to switching the pump on and connecting the outlet hoses to
the system pipework the pump chamber must be primed. The pump must be
primed (filled with water) before starting. Turn on water supply, prime and vent
the pump by unscrewing the priming plug (Fig. 5) slowly until all air escapes and
water emerges. Re-tighten the plug.

4.14 Suction lift installation: Self priming of suction hose.
First ensure both suction and delivery hose connections are airtight. Remove the
priming plug (Fig. 5) and slowly fill the pump body with water, whilst allowing the
air to escape. Replace the plug.

4.15 Suction hose: Ensure the suction hose end is fully submerged in the water
source and the delivery hose is open to enable the pump to vent air.

4.16 Starting The Pump: Turn on the electrical supply to the pump which will
now be operational.
Note: There is an integral on/off switch mounted on the pump (Fig. 5) which must
be turned to the on position.
a) The pump will start and begin to prime the suction pipework.
b) The priming procedure may need to be repeated if pump does not prime
within 5 minutes of starting.
Note: The amount of time required for priming will vary dependent on the
height of the suction lift.
c) Carefully check pump and pipework for leaks whilst pump running and
stationary before leaving the installation unattended.

The pump chamber must be full of water at all times. Seal
damage will result if the pump runs dry.

UNIT STARTING AND OPERATION

STARTING

When the unit is connected to the electrical supply, the green led “Power On” lights up and the yellow
led “On” (pump in operation) indicates that the pump has been started.
The pump continues to operate for a few seconds enabling the system to fill and to reach the required
pressure.
If the failure (red) L.E.D. lights up, this indicates that the pump is out of water or priming is incomplete.
In the event of this happening, check water supply to pump. If all is in order keep the RESTART
button depressed with a tap open and wait until the red failure light goes out. When the button is

released and the tap closed, the control unit will stop the pump at its maximum pressure.

FUNCTIONING

The unit is programmed to perform all the pump control operations automatically.
When particular operational breakdowns occur, such as water failure, obstruction of the suction pipe
etc, the unit recognizes the breakdown and the red led “Failure” lights up, at the same time a stop
signal is sent to the pump to prevent damage caused by its working in the absence of water. After
