1.5 External Exhaust Air Route

An external exhaust air route (see accessories) al-
lows the extracted air to leave the laboratory.
The installation details are supplied with the external
exhaust air route.
When the extraction unit is used in conjunc-
tion with an external ventilation system, a
significant quantity of air is extracted from
the room per hour.
This can create negative pressure within
the room which, when using an air depen-
dent naked flame fed by gas, liquid or solid
fuel, can cause poisonous gasses (e.g.
carbon monoxide) to be drawn into the
working area.
It is therefore essential to ensure that the
fresh air supply is sufficient and that the
environmental air pressure is maintained,
this should then be monitored by an autho-
rized specialist (e.g. a certified Gas Service
Engineer).

2.2 Switching the Unit
ON / OFF
The Silent TS is switched on at the ON switch (B)
(fig. 2b), and off at the OFF switch (A) (fig. 2a).
Extraction starts and stops in conjunction with the
selected operating mode (continuous operation or
automatic operation).
The equipment's operating state is saved
once the suction unit has been operating
for longer than approx. 5 sec.
2.3 Adjusting and Displaying
the Extraction Force
The suction performance of the Silent TS can be
adjusted in 4 stages by the buttons (F) and (H).
This permits the unit's performance to be precisely
matched to different types of materials being extract-
ed.
The extraction force setting is shown on the display
(G).
Increase the extraction force.
Decrease the extraction force.

2.4 Continuous Operation

Continuous operation LED (E)
In the continuous operation mode, the extractor will
begin running as soon as it is switched on, regardless
of other electrical equipment which may or may not
be connected.
The operating mode selector switch (D) is used to
switch between the "continuous" and "automatic"
operating modes.
The selected operating mode is indicated by LED (C)
or LED (E).
Continuous operating mode selection:
• Switch the Silent TS on
- LED comes on
- Continuous operation has now been selected
or
- LED comes on
- The automatic mode has been selected.
- Press the „D" key
- LED comes on
- Continuous operation has now been selected.
• The extractor will switch on.
The extractor is started and stopped with the ON (B)
and OFF (A) switches.
