WARNING
There is a risk of burns or freezing upon coming into contact with the
pump/system.
Depending on the pump and system operating conditions (fluid temperature), the
entire pump can become very hot or very cold.
• Keep a safe distance during operation!
• Allow the system and pump to cool to room temperature!
• Always wear protective clothing, protective gloves and protective goggles when
working.
10.1
Air supply
Check the air supply to the motor housing at regular intervals. Dirt impairs the cooling
of the motor. If necessary, remove dirt and restore unrestricted air supply.
10.2
Maintenance tasks
DANGER
Risk of fatal injury from falling parts!
Falling pumps or individual pump components may result in life-threatening injuries!
• During installation work, secure pump components against falling down with
suitable lifting gear.
DANGER
Risk of fatal electrical shock!
Check for absence of voltage and cover or cordon off adjacent live parts.
10.2.1
Replacing the mechanical seal
There may be a slight amount of drip leakage during the running-in period. Even during
normal operation of the pump, it is normal for there to be slight leakage with the occa-
sional formation of drops.
In addition, carry out a visual inspection regularly. If leakage is clearly visible, replace the
gasket.
Wilo offers a repair kit which contains the necessary parts for replacement.
Dismantling:
WARNING
Risk of scalding!
At high fluid temperatures and system pressures, allow the pump to cool down first
and then depressurise the system.
1.
Disconnect the system from the power supply and secure it against being switched
on again without authorisation.
2.
Make sure it is not live.
3.
Earth the work area and short-circuit.
4.
Close the shut-off devices upstream and downstream of the pump.
5.
Disconnect mains connection cable.
6.
Depressurise the pump by opening the air vent valve (Fig. XXIX/XXX, item 1.31).
NOTICE
For all following work, observe the screw tightening torque specified for the re-
spective thread type (table on screw tightening torques)!
7.
Remove the coupling guard metal sheets (Fig. I, item 1) with a suitable tool (e.g.
screwdriver).
8.
Turn the coupling/shaft so that the four interior hexagonal head screws (twist
guard; Fig. II item 1) are opposite the cover holes.
