Rinsing Off Contaminations; Minor Fi Ne-Grained Contamination; Major Fi Ne-Grained Contamination; Prevention Of Corrosion And Deposits - Ohio Medical Corporation SM30B Operating Instructions Manual

− free and clean fi lters
− no unusual running noise or vibrations
− no impermissible leaks at the shaft sealing
− proper functioning of the auxiliary operating systems
(if available)
3. Check shaft sealing:
 Mechanical seals are maintenance-free sealing systems.
− In case of leaks: Have the mechanical seal with auxiliary
seals replaced by service staff or the manufacturer.
Have auxiliary operating systems (if available) checked
for proper functioning.

7.2 Rinsing off contaminations

D A N G E R
Risk of injuries caused by hot, harmful or
environmentally hazardous media to be pumped!
▶ Do not rinse when delivering harmful or
environmentally hazardous media with the aggregate.
▶ Use protective equipment when carrying out any works
on the aggregate.

7.2.1 Minor fi ne-grained contamination

1. Switch on the aggregate.
2. Remove the screw plug Ue (→ Dimensional drawings,
page 32 et seq.).
3. Collect contamination and escaping operating liquid
and dispose of in an environmentally-compatible way.
4. Screw in the screw plug.

7.2.2 Major fi ne-grained contamination

▶ Replace screw plug Ue by a fi tting.
▶ Close fi ttings before switching on the aggregate.
▶ Fill the aggregate with operating liquid up to the middle
of the shaft .
1. Switch on the aggregate.
2. Open the fi ttings for drainage.
3. Collect contamination and escaping operating liquid
and dispose of in an environmentally-compatible way.

7.3 Prevention of corrosion and deposits

When using water as operating liquid, the pump has to
be protected against corrosion and deposits. Within this
context, certain water quality standards must be met (→
Operating liquid, page 29).
When using operating liquids other than water, please
contact the manufacturer.

7.4 Disassembly

Risk of injuries caused by running aggregate!
▶ Do not touch the running aggregate.
▶ Do not carry out any works on the running aggregate.
▶ Prior to carrying out any assembly or maintenance
works, de-energize the motor and protect it against
restart.
 R I S K O F E L E C T R I C S H O C K
Risk of death from electric shock!
▶ Any electrical works must be carried out by qualifi ed
electricians only.
▶ Observe the IEC 30364 (DIN VDE 0100) and for
potentially explosive areas the IEC 60079 (DIN VDE
0165) standard.
Risk of injuries caused by vacuum and harmful media to
be pumped and operating liquid!
▶ Use protective equipment when carrying out any works
on the aggregate.
▶ Make sure the aggregate is depressurized.
▶ Aft er having drained the aggregate, reliably collect
operating liquid and media to be pumped and dispose
of in an environmentally-compatible way.

7.4.1 Return to manufacturer

✓ Aggregate shut down
✓ Aggregate depressurized
✓ Aggregate completely drained
✓ Electrical connections isolated and motor secured
against re-start
✓ Auxiliary operating systems shut down, depressurized
and drained (if available)
✓ Connecting pipes removed
✓ Manometer lines, manometer and fi xtures removed
1. Loosen fi xing screws.
2. Lift the aggregate out of the system (→ Transport, page
11).
3. Decontaminate aggregate.
4. Attach transport and sealing cover.
5. Send a certifi cate of conformity to the manufacturer. If
required, request a certifi cate of conformity from the
manufacturer.
