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.
Care should be taken to protect pump from frost and freezing.
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 or pump parts manufactured
from plastics. All solder joints should be completed and flux residues
removed prior to pump connection.
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.
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 allow scale or debris to enter pump. Fit inline strainers to
eliminate the problem in systems at risk.
Always install isolating valves to both suction and delivery pipework.
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 time.
Exceptions can be made in the case of
suction lift installations when a footvalve is required, although under
these conditions it is recommended a suitable pressure relief valve is
fitted in the discharge (outlet) pipework from the pump.
General
Locate the pump in a frost free horizontal 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.
Care must be taken when mounting the pump that any noise is not amplified through
loose panels, pipework or other mounting medium. Noise transmission in pipework can
be reduced by fitting flexible hoses to pump inlet and outlet ports and by placing the pump
on anti-vibration mounting feet. Resilient mounting feet and flexible hoses are available
separately as optional extras, contact Stuart Turner for further details.
Ensure the liquid flow is in the direction of the arrows that are moulded onto the reed
switch assembly (vertically upwards) (Fig. 6).
The pump set must be mounted in the horizontal position on its feet, with the discharge
port in the vertical position and must not be mounted in any other way (on its side for
instance).
