In normal operation the pump surface can be hot (up to 125 C) creating a risk
of scalding.
WARNING
During commissioning beware of the risk of scalding from
escaping hot water or steam.
Ÿ
Before switching the pump on, ensure the manual restart knob is engaged with
the motor shaft. Check that the shaft rotates freely and that the knob can be
seen rotating on initial start of the pump.
Venting/ Bleeding
Ÿ
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 vented by using the
manual restart knob.
WARNING
During this operation be aware of the risk of scalding from
escaping hot water or steam. Ensure the pump is switched
off.
Ÿ
Once the system is filled with water, switch off the pump, unscrew the manual
restart knob applying sideways pressure to the screw until water emerges from
it. Screw the manual restart knob back in. Switch pump back on.
NOTE:
A system may take upto 24 hours to bleed all air in the system to
atmosphere. Do not run the pump dry as this will result in bearing failure. Output
of the range of domestic circulators is by 3 speed control.
