EGK 1 Ex2
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.
DANGER
Use in explosive areas
Flammable gasses could ignite or explode. Avoid the follow-
ing hazard sources:
Application area!
Never operate the gas cooler outside the specifications. Ex-
tracting gases or gas mixtures which are also explosive in the
absence of air is prohibited.
Electrostatic charge (sparking)!
The equipment may only be used where normal operating
conditions do not frequently produce flammable, electro-
static discharge.
Always clean plastic housing parts and decals with a damp
cloth.
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
Explosion hazard
Life and explosion risk may result from gas leakage due to im-
proper use.
a) Use the devices only as described in this manual.
b) Regard the process conditions.
c) Check tubes and hoses for leakage.
DANGER
Danger to life and explosion during installation and
maintenance
The unit must not be worked on (assembly, installation,
maintenance) in explosive atmospheres.

DANGER
Toxic, corrosive condensate
a) Protect yourself from toxic, corrosive condensate when
performing any type of work.
b) Wear appropriate protective equipment.
c) Please note the national safety rules!
2.1 Equipment Ambient Temperatures
The equipment may be operated within the following temper-
ature range when observing the specifications in these oper-
ating instructions:
5 °C < T
< 50 °C (41 °F < T

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
NOTICE
Accessories may limit critical operating parameters of
the base unit
Adding accessories may limit critical operating parameters.
Ambient temperatures, zone classifications, explosion
groups, temperature classes or chemical resistances of ac-
cessories may vary from the base unit.
Always include all technical data in the operating instructions
and data sheets of all components in the safety assessment.
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.
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.
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 pre-separator with automatic condensate
drain. Our condensate pre-separators 11 LD spec., AK 20 V or
model 165 SS are suitable solutions.
