Safety Precautions and Warnings
Listed are some, but not all, cautions that must be
observed with vacuum pumps and compressed air
systems . Failure to follow any of these warnings may
result in death, serious injury and property damage
and/or vacuum pump damage.
•
This vacuum pump is designed for use in the
compression of normal atmospheric air only. No other
gases, vapors or fumes should be exposed to the
vacuum pump intake or processed through the vacuum
pump.
•
Disconnect and lock out all power supplies to the
vacuum pump plus any remote controllers prior to
servicing the unit.
•
Relieve all pressure internal to the vacuum pump prior
to servicing.
•
Do not change the pressure setting of the relief valve,
restrict the function of the relief valve or replace the
relief valve with a plug. Over pressurization of system
or vacuum pump component can occur, resulting in
death, serious injury and property damage.
•
Never use a flammable or toxic solvent for cleaning the
air filter or any parts.
•
Do not attempt to service any part while the vacuum
pump is operating.
•
Do not remove any guards or canopy panels while the
vacuum pump is operating.
•
Observe gauges daily to ensure vacuum pump is
operating properly.
•
Follow all maintenance procedures and check all safety
devices on schedule.
•
Never disconnect or tamper with the high air
temperature (HAT) switch.
•
Use the correct fluid at all times.
•
Take extreme care in selecting the proper inlet
filtration system for the vacuum pump. Liquids,
solids and abrasive powders must be prevented from
entering the vacuum pump to prevent mechanical
failure or reduced life.
•
Alterations must not be made to this vacuum pump
without Quincy Compressor approval. Use of parts other
than those approved by Quincy for alterations, repair or
servicing may create hazardous conditions and will void
the warranty.
Installation Hints for Vacuum Service
•
The following items should be used as a guide for the
installation of QSVI vacuum pumps. The list is not
inclusive of every variable possible in the placement
of a vacuum pump. Every vacuum pump installation is
unique and cm must be exercised in the placement of
each pump. If you are unsure of any installation
variable, please consult the factory before start-up.
•
Make sure all connections in piping from the pump to
the chamber or use point are leak tight and secure.
Leaks add load to the vacuum pump and decrease
both available pump capacity and attainable base
pressure.
•
All piping should be as straight as possible with non-
restrictive diameters. Elbows, bends, tees, and tapers
should be used only as absolutely necessary.
•
As a rule of thumb, the inlet diameter of the pump
should be maintained as far into the process as
possible. Consult the factory for piping
recommendations.
•
Keep plumbing and system free of fluids, water, dirt,
and debris that are not part of the process. These can
cause obstructions in the vacuum flow through the
piping and can reduce available pumping capacity.
•
All welds should be vacuum compatible.
•
The work chamber should be clean, dry and empty of
contamination not process related.
