The G1 union connectors (see above) utilise
an ‘O’-ring seal between the union and the
pump. These unions should only be tightened
‘hand tight’ for a good seal to be obtained.
SITING OF PUMP/PIPEWORK
WARNINGS:
Pump Location
If possible 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.
Care should be taken to protect the pump from frost and freezing.
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.
Always install isolating valves to both suction and delivery pipework.
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.
The motor casing can become very hot under normal operating
conditions. Care should be taken to ensure it cannot be touched
during operation.
Ensure the pump cannot be subjected to freezing conditions as
damage may result.
