Safety information
3.2 Principle, intended use
The PURY gas cooler is used to dry and clean coke oven gas, blast furnace gas,
and synthesis gas. It also provides a cleaning functions using stainless steel filter
elements. Napthalene crystallizes out in the moistened filters and is filtered out
with the condensate.
Application areas are the preparation of gases for further analysis with combustion
calorimeters or process gas analyzers.
In the case of toxic or explosive gases, the safety provisions applicable for the
installation location must be complied with.
The gas cooler is installed in a fixed manner and is intended only for use in closed
rooms with adequate ventilation.
Any use beyond this is regarded as non-approved. The manufacturer is not liable
for damage resulting from use. In this case, the risk is borne solely by the
installation engineer/commissioning engineer/owner/operator. Only certified
experts are permitted to make modifications to the gas cooler
(mechanical/electrical/pneumatic changes).
3.3 Personnel and qualification
Gas connections and work on the electrical equipment of the gas cooler should
only be carried out by a skilled person in compliance with safety provisions.
WARNING
Intended use also includes observance of these operating instructions! In
addition to the following safety information, the safety information of linked
system components must also be observed!
Additional equipment or accessory parts not installed, supplied, or made by
UNION Instruments GmbH require manufacturer's approval by UNION
Instruments GmbH! Any warranty is otherwise voided!

Safety information
3.4 Safety information
3.4.1 General safety information
WARNING
Only operate the gas cooler when all protective equipment is present and
operational!
Further safety information:
 Before the corresponding chapters!
3.4.2 Information on specific hazards
WARNING
• After installation, all gas-conveying parts must be checked for leak tightness
according to national regulations.
• Any type of repair that requires opening of the protective cover may only be
carried out by trained personnel!
3.5 Recurring operator training
NOTE
Country-specific regulations regarding recurring training of operators must be
observed by the owner, particularly regarding the handling of gases and
electrical equipment.

Safety information
3.6 Performing a workplace hazard analysis
NOTE
Depending on the National regulations and, if necessary, regardless of the CE
marking of the gas cooler, the owner must prepare a workplace hazard analysis!
Changes to these operating instructions may occur in the future due to further
technical developments. If you desire additional information or if specific problems
arise that are not covered in detail in this manual, you will receive information by

6 Transport, installation, and commissioning
NOTE
The gas cooler is generally commissioned by Union Instrumen
ts GmbH or service
technicians.
When it is not transported, installed, and commissioned by Union Instruments
GmbH (e.g., internal transport/resale), the suitable procedure must be agreed with
Union Instruments GmbH (  Chapter 12 Service).
6.1 Transport
WARNING
Tipping over or dropping of the gas cooler from the pallet or load carrying means
may cause injuries!
 For the unpacking and transporting, observe the weight and dimensions (see
technical data)!
Use a second person or aid if required.
NOTE
In case of transport damage that is indicative of improper handling, a damage
assessment by the transport carrier (rail, mail, shipping company) must be
arranged.

Transport, installation, and acceptance
6.2 Environmental conditions
NOTICE
Comply with environmental conditions for storage and installation!
Comply with environmental conditions! Contact Union Instruments GmbH if the
gas cooler is stored for longer than 3 months or must be operated or stored
outside the prescribed environmental conditions!
6.2.1 Storage conditions
Ambient temperature: -15 - 60°C (-4 - 140°F)
Air humidity: 0 - 95% relative humidity
Ambient pressure: 0.7 - 1.4 bar (11.6 - 16 psia)
