✓ A sufficient quantity of liquid of the specified concentration for the motor fill is
available.
✓ A drain pan for any escaping fill is on hand.
✓ The motor or pump set is positioned vertically and secured against tipping over.
1.
Undo the two screw plugs (a and b) and remove them together with the seal
elements. This results in a filler and a vent opening.
2. To fill the motor, insert the filling funnel (c) horizontally into one of the two
adapter openings. Depending on the sticker colour, fill in or top up fill liquid
until a continuous flow escapes from both openings.
3. For motors which have been supplied "unfilled", wait at least 12 hours to allow
the air to escape. During this period, move the motor or pump set suspended
from the crane slightly to and fro, if possible. Then continue filling it slowly.
Wait another 30 minutes.
4. Check the fill level again.
5. Screw the screw plugs (a and b) back in together with the sealing elements.
Check the screw plugs for tightness. Make sure that the contact faces are clean
and that the joint ring is inserted and free from damage.
NOTE
Fill in the fill liquid slowly.
Fill in with pauses to allow air to escape.
Check the drain plugs at the bottom of the motor for tightness.
1. Suspend the motor or pump set from a crane. Fasten the motor or pump set to
the floor and secure it against slipping.
2.
Carefully lower the crane to slightly tilt the motor or pump set.
3. Monitor the screw plugs for escaping fluid.
4. If required, fit new sealing elements.
7.5 Storage and preservation
WARNING
Pump set tipping over or rolling off
Risk of personal injury!
▷ Always secure vertically positioned pump sets against tipping over.
▷ Always secure horizontally positioned pump sets against rolling off.
CAUTION
Improper storage
Damage to the power cables!
▷ Support the power cables at the cable entries to prevent permanent
deformation. Observe the minimum bending radius
16)
of the cables.
▷ Only remove the protective caps from the power cables at the time of
installation.
7.5.1 Storing new submersible borehole pumps
To store for a prolonged period pump sets / motors which have not been used yet
ensure the following conditions are met:
1.
Pump set / motor removed from packaging
2. Vertical (with the motor below)
Checking the
screw plugs.
