Air connection
Clean air is drawn in via the air connection during a device in-
spection or adjustment.
The air can be drawn in:
●Directly
No accessories are connected to the air connections.
●Using an ambient air hose
Anambientairhoseisconnectedtotheairconnection,withthe
free end positioned in a place where there is clean air.
Forexample,theambientairhosecanberoutedthroughan
open window so that ambient air is drawn in instead of room air.
The ambient air hose can be purchased as an accessory.
The air connection is equipped with an internal carbon dioxide
lter.ThelteristestedbySEWERINServiceaspartofthean-
nual maintenance.

3 Preparing for start-up
Note:
Start-up may only be carried out by specialist technicians.
3.1 Suitable environment
The test set may only be operated in spaces that meet the fol-
lowing requirements:
●clean ambient air
●well ventilated
●dry
●dust-free
●vibration-free
●no direct sunlight on test gas cans
If the set-up location does not meet the ambient air and ventila-
tionrequirements,thetestsetcanstillbeoperatedatthisloca-
tion,providedthatanambientairhoseisused.Thehosemust
be positioned so that clean air can be drawn in.
3.2 Position of use
3.2.1 Overview
The test set may be operated in the following operating positions:
● placedonahorizontal,atsurface
−upright
−tilted and supported by the bracket
● mountedonavertical,load-bearingsurface(wallmounting)
