ASSEMBLY
To protect the unit during tansit the pump is supplied with the flow switch removed.
Follow the instructions below to complete assembly.
zEnsure all components are clean and free from debris.
zScrew complete flow switch body assembly into pump body, ensuring ‘O’-ring is
fitted (Fig. 2).
zTighten to 7 – 10 Nm (5 – 7 lb ft).
zCare should be taken when handling the reed switch not to damage the reed or
cable.
zFor correct operation of the flow switch, the reed must be secured to the body
(Fig. 2).
zFirstly feed the tie wrap through the retainer on the reed switch, ensuring that the
tie wrap serrations are facing outwards (Fig. 3).
zLocate the reed switch within the body groove as highlighted X-X (Fig. 2), and feed
the tie wrap through the second catch. Note the arrow on the reed switch should
be pointing up, towards the outlet connection.
zThe tie wrap can now be pulled tight to secure the reed and the excess cut to
length as shown (Fig. 4).

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.
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 –
Plumbing.
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 does not exceed 50 oC.
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 TechAssist team on [phone].
C Water flow
1.17 For this pump to operate correctly there must be a minimum gravity flow of at
least 1 l/min through all outlets to be pumped.
D Pipework – general
1.18 Secure pipework: Ensure pipework to and from pump is independently
supported & clipped to prevent forces being transferred to inlet and outlet
branches of pump.
1.19 Flux: Solder joints must be completed and flux residues removed prior to
pump installation (flux damage will void any warranty).
1.20 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.
1.21 DO NOT introduce solder flux to pump parts manufactured from
plastic.
1.22 DO NOT allow contact with oil or cellulose based paints, paint thinners
or strippers, acid based descalents or aggressive cleaning agents.
1.23 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.
E Plumbing installation regulations
1.24 The plumbing installation must be installed by a qualified person and in
accordance with local regulations.
F Electrical/installation regulations
1.25 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, 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 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 on a horizontal surface only, with the outlet
facing vertically upwards.
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).

WARNING: This appliance must be earthed.
The wires in the mains lead (supply cord) 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:
zThe wire which is coloured green and yellow must be connected to the
