Danger of burning when touching the pump!

8.1 Initial start-up

Ensure that the pipe system is properly filled and air-vented. The pump rotor
can assembly is automatically vented after a short running period. Short-term
dry running will not harm to the pump. If, however, manual venting of the pump
may become necessary please following procedure:
• switch-off pump
• close the discharge isolating valve
WARNING! Risk of scalding!
Depending on fluid temperature and system pressure there is the possibility
of hot water in liquid or gaseous state suddenly erupting under great force
when opening the vent plug. Note the severe danger of scalding!
• Place a container under the the pump to catch any water that may run out
• Protect electrical parts from the leaking water
• Remove the smaller, round peferated center part of the nameplate
• carefully loosen the vent plug with a suitable screwdriver (Fig. 5), continue until
water appears, but do not remove
CAUTION! Risk of damage to the pump!
There is the possibility, depending on the system pressure, of the pump
jamming with the vent plug open. Before switching on the pump refit and
tighten the vent plug.
• After 30 seconds re-tighten vent plug
• reopen discharge isolating valve
• switch on pump
