DANGER
Electrical voltage
Electrocution hazard.
a) Disconnect the device from power supply.
b) Make sure that the equipment cannot be reconnected to
mains unintentionally.
c) The device must be opened by trained staff only.
d) Regard correct mains voltage.
DANGER
Toxic, corrosive gas/condensate
Sample gas/condensate may be hazardous to health.
a) If necessary, ensure a safe gas/condensate discharge.
b) Always disconnect the gas supply when performing
maintenance or repairs.
c) Protect yourself from toxic/corrosive gasses/condensate
when performing maintenance. Wear appropriate pro-
tective equipment.
DANGER
Potentially explosive atmosphere
Explosion hazard if used in hazardous areas.
The device is not suitable for operation in hazardous areas
with potentially explosive atmospheres.
Do not expose the device to combustible or explosive gas mix-
tures.
CAUTION
Hot surface
Risk of burns
The housing can be up to 60 °C during operation.
Allow the unit to cool down before working on it.
3 Transport and storage
Only transport the product inside the original packaging or a
suitable alternative.
The equipment must be protected from moisture and heat
when not in use. It must be stored in a covered, dry and dust-
free room at a temperature of -20 °C to 60 °C (-4 °F to 140 °F).
In particular for sample gas coolers with stainless steel heat
exchangers for applications (suffix -O2), it is essential to rule
O2
out any contamination of components in contact with the
media during storage.
4 Installation and connection
4.1 Installation site requirements
The unit is intended for wall-mounted or table-top use in en-
closed areas. Adequate protection from the weather must be
provided when used outdoors.
Install the unit leaving enough room below the cooler to dis-
charge the condensate. Leave room above for the gas supply.
BX450028 ◦ 03/2024
Be sure to maintain the approved ambient temperature. Do
not obstruct the convection of the cooler. The vents must have
enough room to the next obstacle. The distance must espe-
cially be a minimum of 10 cm on the air outlet side.
Ensure adequate ventilation when installing in enclosed
housings, e.g. analyser cabinets. If the convection is inad-
equate, we recommend aerating the cabinet or installing a
fan to lower the inside temperature.
CAUTION
Contamination of cleaned components
For sample gas coolers with stainless steel heat exchangers
for O applications (suffix -O2), contamination with oil,
2
grease, dust, particles, lint, hair, etc. must be ruled out for fire
protection reasons when working on components that come
into contact with media. If necessary, adapt your operational
and organisational measures with regard to the work cloth-
ing to be used, hygiene regulations, etc. If necessary, move
such work to a suitable, cleaner work area.
4.2 Installation
Run the gas supply to the cooler with a downward slope. The
gas inputs are marked in red and additionally labelled "IN".
If a large amount of condensate accumulates, we recommend
using a condensate trap with automatic condensate drain.
Our condensate drains, 11 LD spec., AK 20 V, or model 165 SS,
are suitable.
Glass vessels and automatic condensate drains are available
for draining condensate for external mounting below the
unit. When using automatic condensate drains, the sample
gas pump must be installed upstream of the cooler (pressure
operation) to ensure proper function of the condensate drain.
If the sample gas pump is located at the cooler outlet (suction
operation), we recommend using glass condensate traps or
peristaltic pumps.
With the option for high-purity water or oxygen (suffix -H2/-
O2), the components are each supplied in separate packaging.
To prevent soiling, these should only be unpacked shortly be-
fore use.
4.2.1 Connecting the filter gas connections (optional)
The connection between the heat exchanger outlet and the fil-
ter inlet does not have tubing included. The connection G1/4
or NPT 1/4" (filter head marked NPT) for the gas outlet must be
carefully and properly connected using a suitable screw con-
nection.
When ordering the cooler with the option filter without Mois-
ture detector, a bypass may be connected to the filter head.
The filter head is intended for a G1/4 internal screw thread
which is plugged at the factory. To use it, unscrew the plug
and screw in a suitable screw connection. Pay attention to
leaks.
NOTICE
Installing filters limits the maximum approved operating
pressure in the system!
Operating pressure ≤ 2 bar
