A drain pan for any escaping fill is available.
1. Place the motor or pump set down in a vertical position. Secure it against
tipping over.
2. Undo the two screw plugs (a and b) and remove them together with the sealing
elements.
ð
If the liquid level is visible in one of the two openings, the motor fill is
sufficient.
ð
If the liquid level is not visible, 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. Screw the screw plugs (a and b) back in together with the sealing elements.
Check that the screw plugs are fitted tightly. Make sure that the contact faces
are clean and that the joint ring is inserted and free from damage.
Checking the
screw plugs
1. Suspend the motor or pump set from a crane. Locate the motor or pump set in
position on 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 any escaping liquid.
4. Replace the sealing elements if required.
