1.1 Intended Use

This unit is intended for industrial use in gas analysis systems.
It's an essential component for conditioning the sample gas to
protect the analysis instrument from residual moisture in the
sample gas.
Please note the specifications in the data sheets on the spe-
cific intended use, existing material combinations, as well as
pressure- and temperature limits.
1.2 Types
The device is delivered with different configurations. The part
number given on the type plate informs you about the spe-
cific configuration of your device.

1.3 Scope of delivery

• Cooler
• Product documentation
• Connection-/mounting accessories (optional)
2 Safety instructions
The equipment must be installed by a professional familiar
with the safety requirements and risks.
Be sure to observe the safety regulations and generally applic-
able rules of technology relevant for the installation site. Pre-
vent malfunctions and avoid personal injuries and property
damage.
The operator of the system must ensure:
• Safety notices and operating instructions are available
and observed,
• The respective national accident prevention regulations
are observed,
• The permissible data and operational conditions are
maintained,
• Safety guards are used and mandatory maintenance is
performed,
• Legal regulations are observed during disposal,
• compliance with national installation regulations.

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.
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).

4 Installation and connection

4.1 Installation site requirements

The unit is only intended for wall-mounted use in enclosed
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.
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.
When wall mounting the sample gas cooler, be sure the wall
or the cabinet provide adequate weight bearing and stability.
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 V38, AK 20, AK 5.5 OR AK 5.2, 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.
