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 conned

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 buttery 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 specied 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 su󰀩cient.

● 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 buttery nuts on the nozzle to ensure a secure

mechanical and electrical contact.

3 Operation │ 5

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.
