Safety Regulations
Please comply with safety standard DIN EN
1012-2 for vacuum pumps.
Alterations to the side channel compressors may
be effected only after agreement by the factory.
The mains-powered VariAir Con-
verter uses dangerous voltages.
The converter must be isolated
from the mains when any work is
being carried out on it. Disregarding the regula-
tions can result in property damage or serious
or fatal injuries. The capacitors can contain
dangerous voltages for some time after the
mains is switched off. A 5-minute discharge time
is therefore to be allowed before the terminal
cabinet is opened.
Air compression will generate high
temperatures: Install compressors
in a position where hot surfaces
cannot be touched. Protect the
area around them or install warning signs.
Application
Side channel compressors are used for the
generation of vacuum.
Their characteristics apply up to a height of
800 m above sea level. They are unsuitable for
the transport of toxic, flammable or aggressive
media.
When operating side channel compressors,
ensure that only normal atmospheric air can be
taken in. Should dusty media be handled, igni-
tion temperatures of dust/air mixtures generated
must not be reached.
Transport and storage
Store side channel compressors in a dry place
and protect against water splashes.
Lift and transport by using suitable belts.
Installation
It is recommended to install the compressor with
easy access for maintenance.
optimal optimal improper
Clearance between compressors and adjacent
walls should be no less than 10 cm of free space
in order to ensure sufficient air flow for cooling.
J.Schmalz GmbH prior to installation under noise
insulation canopies, contact.
Ambient temperatures must not exceed 40°C.
Side channel compressors may be installed
horizontally on a stand or vertically without a
stand (with the motor at the top).
The stand has vibration damping elements in the
fixing holes (Pos. 204). The mounting screws just
as firmly, that the foot is not in direct contact with
the ground (gap ≥ 0.5 mm).
The installation face must be flat to ensure a
safe level.
Assembly
Ensure correct dimensions of and clean pipelines
(no weld spatter, chips or similar contamination).
Ensure that pipelines are no less in diameter than
connecting threads. Use next larger diameter for
pipelines exceeding 2 m in length.
Keep connections free from oil, grease, water
and other contaminants.
Avoid deviation from maximum pressures by
installation of safety valves.
Remove end caps at SA. Do not connect to
pipeline yet.
Motor connection
Installation and commissioning of the VariAir
Converter:
Only qualified persons may install or commission
this equipment.
Observe the operating instructions for the
FU Frequency Converter!
Connection of compressors to mains supply must
comply with applicable regulations.
Connect Frequency Converter based on con-
necting diagram. This work should be carried
out by an experienced electrician only. Check
for connecting voltage and frequency.
Commissioning
Connect inlet line at SA. Avoid mechanical
stresses by pipe or casing connection by using
flexible connectors.
Blocked inlet filters or excessive pressure dif
-
ferentials will cause unacceptable, excessive
operating temperatures (remedy: pressure-
reducing valve).
Avoid exceeding maximum pressure values by
installing safety valves.
Should vacuum safety valves be retrofitted, set
to maximum operating pressure as stated on the
rating plate during initial operation. Any safety
valves installed in the factory will be preset.
Maintenance
Regular maintenance of your compressor will
yield the best results. Maintenance intervals will
depend on use and operating conditions.
Before carrying out any mainte-
nance, disconnect motor from
mains and reliably prevent unin-
tentional restarting.
Clean fan hood and compressor surfaces to
prevent overheating.
