11.2 Bottom collecting sump/perforated metal plate insert
The bottom collecting sump, or drawers serves to collect any leaking fluids and may only be used in combination with
a suitable perforated metal plate insert. In the case of a leak, the liquid in the floor collecting tray must be mopped up
with suitable means, the selection of which is up to the user.
11.3 Drawers/2nd storage level
All drawers have been designed in such a way that they are permanently drawn in the cabinet or automatically drawn
into the cabinet in the case of fire, making it possible to close the cabinet doors.
Drawers may only be adjusted in height by authorised asecos staff as the safe drawing back of the drawers in the cabi-
net in case of a fire has to be guaranteed!
11.4 TRG and G90-models
• Assembly rails
The horizontal assembly rails serve to accommodate the pressurised gas fittings. The assembly rails can be
height-adjusted as follows:
Slightly loosen screws, reposition the assembly rail and retighten screws.
• Bottle holder
is permanently attached to the rear wall of the housing and has a belt for fixing of the gas bottle(s)
• Fold away ramp
has been fitted in the factory and automatically stops in closed position. To use, simply pull the flap down and
push down completely. Return to cabinet after use.
• Pipe conduit
The head part of the cabinet has fittings for a large number of pipe conduits.
Drill through the head part from the top for pipe conduits in one of the preset positions with exactly the diame-
ter of the pipe to be fitted. The pipe can now be introduced without any further insulation measures.
• Ermeto screwed connection
The preparation for Ermeto screwed connections is made by the factory on the ceiling of the cabinet. Commer-
cially available Ermeto screwed connections can then be fitted through the R3/8" internal thread.
12. Earthing
All models can be connected via an earthing connection in the head part or on the rear wall to an equipotential bon-
ding. Cabinets in which refilling work can be performed should additionally be equipped with an earthing terminal
(upon request and with extra charge) which must be connected with the refilling containers.
13. Ventilation
All models can be connected to a technical exhaust air system via the extraction air outlet (DN75). Please refer to the
applicable national regulations for the prescribed air replacement rate, max. pressure losses and waste air ducts.
The supply and waste air connectors are not prefitted in some models; they are supplied with the cabinet and must be
screwed to the bored hole openings in the head part.
Please refer to Annex 1 for the position of the supply and waste air connectors.
Models VBF.60.xxx
Bottom cabinets with floor suction (if a base is used) obtain their supply air from beneath the cabinet. If a bottom ca-
binet without base is used, i.e. is directly positioned on the floor, it will require supply air from the rear wall of the ca-
binet. In this case, the black rubber stopper must be removed from the supply air inlet.
Models TRG.205.xxx, G90.xxx
In compliance with DIN 12925 Part 2 (EN 14470 Part 2 after its publication), pressured gas cylinder cabinets must be
connected to a technical waste air system which leads outside at a safe place.
An air change rate of 10 is prescribed for combustible and fire-conducive gases and a minimum air change rate of 120
for toxic gases. The ventilation system must be permanently in operation. The drop in pressure in the cabinet may not
exceed 150 Pa. The incoming speed of the air must be at least 20cm/s.
If, however, a cabinet serves the sole purpose of storing inert gases then it needs not be connected to an exhaust air
system.
