Symbol Description
FD
Always apply a liquid sealant (e.g. Hylomar SQ32M) to sealing surfaces
marked with this symbol.
ü
A suitable container for the leakage is on hand.
ü The pump set is positioned horizontally on a level surface and is protected
against rolling off. (
ð Section 3.2, Page 12)
1. Place the container underneath screw plug 903.01.
2. Remove screw plug 903.01 with joint ring 411.01. Observe the plate "Leakage
drain".
3. Drain the leakage.
ð If there is no leakage or, after several years of operation, only a small
amount, the mechanical seals are working properly. If the leakage exceeds
2 litres, the mechanical seals are defective and must be replaced.
4. Re-insert and tighten screw plug 903.01 with new joint ring 411.01.
