1. Remove the mains plug from the plug socket.
2. Close all the shut-off devices in the pressure
line.
CAUTION!
Danger of injury from hot
water

the closed pressure side
(>10 min.), the water in the
pump can become very
hot and may escape un-
controlled!
■
Disconnect the pump
from the mains supply
and allow the pump and
water to cool down.

Put the pump into oper-
ation again only after all
the faults have been

7 MAINTENANCE AND CARE
7.1 Check the air pressure in the storage
vessel
NOTE
Check the air pressure in the storage
vessel at regular intervals. It must not
exceed 1.5 bar (see Section "Commis-
sioning: Checking the Air Pressure in the
Storage Vessel").
1. Disconnect the pump from the mains supply
and secure to prevent restarting. The pump
stops automatically.
2. Open a shut-off device (valve, spray nozzle,
water cock) in pressure line (10).
3. Drain water until the pump is completely
empty.
4. Open the cover on the rear of the storage
vessel.
5. Check the air pressure at the valve using an
air pump or tyre filler equipped with a pres-
sure gauge. Correct the air pressure, if ne-
cessary.
6. Close the cover on the rear of the storage
vessel again.
7. Put the pump into operation again.
