5. COMMISSIONING/OPERATION ATTENTION
FILLING
Ensure no fluid drips onto the pump motor or its electrical connections during
installation, venting or operation as when the pump is energised this may create a
risk of electric shock.
In normal operation the pump surface can be hot (up to 125
being burnt.
Water and water/glycol mixtures in the ratio of 1:1.
Glycol mixtures require a reassessment of pump hydraulic data in line with the
increased viscosity and depending on mixing ratios.
Use only approved makes of additives with corrosion inhibitors and follow
manufacturer's instructions.
Do not leave system empty without protection from corrosion inhibitor.
During this operation ensure the pump is switched off.
Open both valves either side of the pump.
VENTING / MANUAL RESTART
Protect all electrical parts against the leaking water.
During this operation be aware of the risk of scolding from escaping hot water
or steam.
When the system is filled with water the pump will normally self vent air within a
short while of switching on.
In cases where the pump venting is slow (identified by pump noise) the pump
bearings may be quickly vented by using: -
a) THE MANUAL RESTART KNOB. Switch off the pump. Unscrew the manual restart
(Fig 4b) applying sideways pressure to the screw, with a screwdriver, until water
emerges from it. Screw the manual restart knob back in. Switch pump back on.
