Ensure that repair is done only by an appropriately trained and supervised tech
-
nician. Obey local and national safety requirements. Ensure that the technician is
familiar with the safety procedures which relate to the products processed by the
pumping system. Ensure that the pump is decontaminated before repair and that
you take adequate precautions to protect people from the effects of hazardous sub-
stances if contamination has occurred.
Read the
instructions for use
for the equipment carefully, especially sections
“Safety informations“ and “Use and operation“. If necessary order ”Instructions for
use” from VACUUBRAND.
Wear parts have to be replaced regularly.
In case of normal wear the lifetime of the
diaphragms and valves is > 10000 operating hours. Bearings have a typical durability
of 40000 h. Motor capacitors have a typical durability in the range of 10000 to 40000 h de-
pending strongly on the operation conditions like ambient temperature, humidity or load.
• Check every capacitor regularly by measuring its capacity and estimating its op
-
eration time. Exchange old capacitors early enough to prevent a failure. If an
overaged motor capacitor fails it might get hot and even melt and may cause a
flame to form which could be
dangerous for persons and equipment in the
vicinity
. The capacitors have to be replaced by an electrician.
If hazardous or corrosive substances have been pumped:
- The device will be contaminated with the process chemicals which have been
pumps during operation. Ensure that the pump is decontaminated before mainte
-
nance.
- Take adequate precautions to protect people from the effects of dangerous sub-
stances. Wear appropriate safety-clothing, do not inhale and avoid contact with
skin.
Before starting repair check that the required parts are available and of the correct
type before you start your work.
- Check the operating sequence mentally using exploded view drawings, spare
parts lists and circuit diagram on feasibility, safety requirements and consequenc
-
es on safety and function of the equipment.
-
Isolate equipment from mains
and
wait two minutes
before starting mainte-
nance to allow the capacitors to discharge.
- Vent the pump, isolate the pump and other components from the vacuum system.
Allow sufficient cooling of the pump. Drain condensate, if applicable.
☞
Ensure that the pump cannot be operated accidentally. Never operate the
pump if covers or other parts of the pump are disassembled. Never operate
a defective or damaged pump.
Ensure that
maintenance
is done only by suitably trained and supervised techni-
cians. Ensure that the maintenance technician is familiar with the safety procedures
which relate to the products processed by the pumping system.
In order to comply with law (occupational, health and safety regulations, safety at
work law and regulations for environmental protection) vacuum pumps, components
and measuring instruments returned to the manufacturer can be repaired only when
certain procedures (see section
”Notes on return to the factory”
) are followed.
