SITING OF THE PUMP/PIPEWORK
WARNINGS:
Pump Location
If possible site the pump in a location where in the unlikely event of a
liquid leak, any spillage is contained or routed to avoid electrics or
areas sensitive to liquid damage.
Ensure pipework to and from pump is independently supported to
prevent stress on the pump inlet and outlet branches.
Do not fit a non-return valve, or devices which contain non-return
valves, in the suction (inlet) pipework to the pump. Exceptions can
be made in the case of suction lift installations when a footvalve is
required.
When a footvalve is required on installations that incorporate
automatic pump control, it is recommended that a suitable pressure
relief valve be fitted in the discharge (outlet) pipework from the pump.
Do not run against a closed valve for periods longer than 5 minutes.
Do not allow plastic pump parts to come into contact with oil or
cellulose based paints, paint thinners or strippers, acid based
descalents or aggressive cleaning agents.
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.
Care should be taken to protect the pump from frost and freezing.
Always install isolating valves to both suction and delivery pipework.
The motor casing can become very hot under normal operating
conditions. Care should be taken to ensure it cannot be touched
during operation.
Site the pump horizontally in a dry, frost-free position where it cannot be sprayed with
water and as close to the liquid source as possible.
The pump enclosure must be ventilated and there should be a minimum clearance of
80 mm between the pump and housing on all sides.
To prevent loss of pressure through pipework, use pipe size to match pump whenever
possible, minimising 90° bends.
It must be ensured that storage capacity of the liquid supply is adequate for the flow
rates required by the pump.
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.
Isolating valves should be fitted in suction and delivery pipework to enable easy isolation
and access to the pump.
When the 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 the inlet pipework is fitted with an inline strainer.

Mounting Foot Securing
Some pumps within the range are fitted with plastic mounting feet. If there is a
requirement to secure the pump via the mounting feet, the following points should be
noted.
The pump should be mounted only in the horizontal position.
Floor mounting is the preferred
orientation but wall mounting is
possible providing all fixing
holes provided are used.
*Air locking possible. Special care
required to vent the pump casing
of air with this orientation.
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.

Pump Mounted Above Liquid Source (Suction Lift)
The pumps can be used in a suction lift installation providing the height of lift is within the
limits specified in the limits of application section (Fig. 8).
A footvalve and strainer must always be used (except X201 when used on a self priming
installation) and the suction pipework size must match the pump.
Lay the suction piping over the shortest possible distance and ensure there is a constant
rise from the liquid source to the pump. Any high spots will cause air pockets to form,
reducing system efficiency.
Ensure all joints in suction pipework
are completely airtight. Failure to
comply will result in loss of prime.
The intake of the footvalve/strainer
should be positioned such that it cannot
be blocked with debris or silt that are
frequently found in the bottom of sumps
and wells.

ELECTRICAL INSTALLATION
WARNINGS:
The electrical installation must be carried out in accordance with the
current national electrical regulations and installed by a competent
person.
Before starting work on the electrical installation ensure the power
supply is isolated.
Where any of the pumps are installed in an area where there is a risk
of water spillage and particularly in the case of the X201, it is
recommended that a residual current circuit breaker having a rated
current not exceeding 30 mA, be installed in the supply circuit. This
may be part of a consumer unit or a separate unit.
This appliance 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 standard single phase pumps are suitable for a supply of 230V, 1 Phase, 50Hz.
Other voltages and frequencies are available on certain models and it is therefore very
important to ensure the voltage and frequency on the pump rating plate matches the
supply.
When installing a 230V, 1 phase, pump in the United Kingdom, means for disconnection
must be incorporated in the fixed wiring according to the Wiring Rules. This can be done
by permanently connecting the pump to the mains supply via a double pole switched, fused
connection unit complying with BS 1363-4.
The standard three phase pumps are suitable for a supply of 400V, 3 Phase, 50Hz and
should be connected via a starter complete with suitably sized thermal overload.
All motors exceeding 370 watt output should be provided with control equipment
incorporating means for protection against overload.
The spur box (fused connection unit) or starter to which the pump is connected should
be mounted in an easily accessible position and labelled if confusion is possible to allow
easy isolation of the unit.
All pumps are continuously rated.
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 (see Fig. 9).

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 liquid at all times. Seal damage
will result if the pump runs dry.
- 13 -
E
Cont ...
1. System Flushing
Some pumps incorporate 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. Liquid Supply
Always ensure that liquid storage capacity is adequate to meet the demand.
Ensure the pump chamber is full of liquid before starting the pump. Failure
to do this could result in seal damage. To ensure dry running does not
occur the pumps must be primed as described in the priming section. Do
not run pump dry.
3. Ensure electrical supply is compatible with the details that are stated on the pump
rating plate. (The wrong voltage or frequency can be dangerous and may damage
the pump.)
4. Priming
a) Flooded suction installation.
The pump must be primed (filled with liquid) before starting. Turn on liquid
supply, prime and vent the pump by unscrewing the priming plug (Fig. 19)
slowly until all air escapes and liquid emerges. Re-tighten plug.
b) Suction lift installation.
Prime the suction pipework and pump by filling with liquid via the pump discharge
connection or by filling the suction pipework before attaching to the pump.
c) X201 only (suction lift installation)
This pump is capable of priming the suction hose with liquid on installation.
Ensure both suction and delivery hose connections are air tight. Remove the
yellow priming plug located on the top of the pump housing. Fill the pump body
with liquid slowly allowing the air to escape.
Fully submerge suction hose in liquid source. When all is satisfactory the
electrical supply can be switched on, (whilst the pump is priming, the delivery
must be open). If nothing happens after 5 minutes, switch the pump off, re-prime
the pump again.
Note: The amount of time taken for priming and the number of times priming is
required will vary dependant on height of suction lift.
The suction pipe can also be fitted with a footvalve and strainer which will ensure
the pump and pipework remains primed at all times. The suction hose should not
exceed 32 mm dia bore.
