1.2 Purpose
Large volumes of CO2 can be released in well shafts and
ventilation and purge shafts as a result of pressure drops. High
concentrations of CO2in respiratory air leads to disorientation,
unconsciousness and death.
SEWERIN's FLIS-EX (FLIS for short) helps ventilate and purge
shafts.
1.3 Intended use
The following work can be performed in shafts with the FLIS:
● ventilating (supplying fresh air)
● purging (extracting harmful gases)
Always observe national regulations for the respective application
when using the FLIS. For example, in Germany please observe
the following:
● DGUV (German Social
Accident Insurance Institu-
tion) regulation 113-004
Working in tanks and conned
spaces
● DGUV provision 22 Accident prevention regulation
for wastewater engineering
plants
● DGUV regulation 103-003 Working in enclosed spaces in
wastewater engineering plants
● DGUV regulation 103-002 District heating distribution
plants
● DGUV principle 313-002 Selection, training and commis-
sioning of experts for measuring
pursuant to BGR 117 – part 1,
DGUV principle 313-002
● DGUV regulation 113-001 Explosion protection regulations
(Ex-RL)
The FLIS must not be used in oxygen-enriched atmospheres.
Otherwise the device will not be explosion-proof.

2 Features
The FLIS has been constructed in accordance with the European
explosion protection standard ATEX 100a and complies with the
CENELEC recommendations.
The FLIS contains the following electrical equipment:

The FLIS comes with:
● suction hose with cage
●extension hose
●extension hose in canister holder
The cage of the suction hose prevents dirt from getting into the
device (e.g. branches, leaves). Extension hoses do not have a
cage.
The hoses are attached to the FLIS using the bayonet tting and
secured with a buttery nut.
Hoses can be connected to each other. Using more than three
hoses can reduce the air volume of the FLIS.
4 │ 3 Operation
3 Operation
The FLIS can both ventilate and purge shafts. Either of the two
options is selected depending on:
● the type and size of the shaft
● the anticipated gases
●
the regulations of the responsible German Social Accident
Insurance Institution or other legal stipulations
AWARNING!
Risk of poisoning from toxic gases
Shafts may contain harmful toxic gases.
●
When purging, always wait the specied time before
entering the shaft (section 3.2).
●
Always measure the gas concentration before entering.
● Always take a gas measuring device into the shaft with
you, so that you can respond immediately if the suction
capacity of the FLIS is no longer sucient.
● Never switch o the FLIS if there is anyone in the shaft.
3.1 Preparing the device
Regardless of how the FLIS will be used (for ventilating or
purging), it is always prepared for use as follows:
1. Place the FLIS at the edge of the shaft.
− The FLIS must be stable and protected against shocks.
− Make sure that coarse dirt does not get into the FLIS de-
vice.
2. Open the inspection cover.
3. Attach the hoses.
− The table below contains information about the connection
options and the ways in which hoses can be combined.
− Tighten the buttery nuts on the nozzle to ensure a secure
mechanical and electrical contact.

4. Dangle the hoses in the shaft as follows.
− Ventilate: extension hose
− Purge: suction hose
The cage of the suction hose must be inside the shaft.
