Preparing Of Pipe Connection; Silencer; Pipe Connecting; On / Off Switch - AirTech ASC series Installation Und Betriebsanleitung

Pre pa ri ng o f p i pe c on n ect io n
When a pipe is connected to the side channel blower appropriate
the connection diameter of the side channel blower, no damage of
the pipe is expected by vibrations of the machine.
• Make sure, that temperature-affected longitudinal expansions of
the pipe will be compensated, if necessary use bellows
• Make sure that the pipe will cause no stress on the side channel
blower's connection, if necessary use bellows
• Make sure that the line size of the pressure line over the entire
length is at least as large as the gas inlet / suction connection of
the side channel blower
• Make sure that the discharge line either slopes away from the
side channel blower or provide a liquid separator or a drip leg
with a drain cock, so that no liquids can back up into the side
channel blower.
In case of doubt seek advice from your AIRTECH representative!
Si le nc e r
Single-stage and multi-flow machines are delivered with preassem-
bled silencers.
For multi-stage machines, the pressure-side silencer is supplied
loose for packaging-related reasons and must be installed by the
operator using the supplied fastening material (screws/threaded
bolts and nuts).
Pipe c o n ne cti ng
• Connect the suction line.
• Connect the pressure line.
• Make sure that the gas connections are open.
• Make sure that all provided covers, guards, hoods etc. are
mounted.
• Make sure that cooling air inlets and outlets are not covered or
obstructed and that the cooling air flow is not affected adversely
in any other way.

Vacuum operation:
• In order to relieve excess vacuum or to limit the air flow use vent
valves. Do not control the vacuum or the flow by throttling of
suction or discharge lines. Conveying bypass air will let the side
channel blower run cooler and draw less power.
Pressure operation:
• In order to relieve excess pressure or to limit the air flow use
bleed valves. Do not control the pressure or the flow by
throttling of suction or pressure lines. Bleeding excess air will let
the side channel blower run cooler and draw less power.
On / o ff sw it c h
The side channel blower comes without on/off switch. The control
of the side channel blower is to be provided in the course of
installation.

DANGER!
Lethal electric shock due to contact with live parts.
WARNING!
All work must only be carried out by qualified personnel and
when the machine is stationary.
● Switch off the machine and secure it against restarting. This
also applies to auxiliary circuits (e.g. standstill heating).
● Check there is no voltage!
● Establish a safe protective earth connection before starting
work!
● Deviations from the rated values for voltage, frequency, curve
shape, symmetry of the feeding network increases the heating
and influence the electromagnetic compatibility.
DANGER OF EXPLOSION!
The machine must not be operated with a higher voltage than
indicated on the rating plate.
