2.2  Important safety information

•  Before using the Isomix-F, read this operating manual 

through carefully.

•  Connect the Isomix-F only to a power source that corre-

sponds to the mains voltage specified on the rating plate of 
the Isomix-F.

•  The power supply to the Isomix-F must be disconnected 

prior to maintenance, cleaning and repair work.

•  Maintenance, cleaning and repair work may be carried out 

by trained specialist personnel only.

•  The Isomix-F must not be used if it is damaged or is no 

longer operating correctly. In this case, contact your spe-
cialist dealer immediately.

•  Observe the maintenance instructions and intervals.

•  Protect the Isomix-F from the weather.

•  Never use the Isomix-F outdoors.

•  The unit may be used only in accordance with its intend-

ed use.

2.3  Intended use

The control station Isomix-F is used for constant mainte-
nance of the flow temperature in surface heating systems. 
The control station is intended for use in dry rooms in resi-
dential or commercial areas. It is usually installed in the heat-
ing room or in a distribution cabinet.

The Isomix-F is not intended to be operated by people 
(including children) with limited physical, sensory or mental 
capacities, or by people with insufficient experience or previ-
ous knowledge.

2.4  Foreseeable misuse

The following is considered to be foreseeable misuse:

•  Operating the Isomix-F beyond its specifications.

•  Improper use of the Isomix-F.

•  Modifications to the Isomix-F that have not been agreed 

with the manufacturer.

•  Use of replacement or wear parts that have not been 

approved by the manufacturer.

•  Operating the Isomix-F outdoors.

2.5  Responsibilities of the plant operator

The plant operator must ensure that:

•  the Isomix-F is used only for its intended purpose

•  the Isomix-F is installed, operated and maintained accord-

ing to the specifications of the installation and operating 
manual

•  the Isomix-F is operated only in accordance with local reg-

ulations and occupational health and safety regulations

•  all precautionary measures have been taken to avoid dan-

gers originating from the Isomix-F

•  all precautions for first aid and firefighting have been taken

•  only authorized and trained users have access to the 

Isomix-F and operate it

•  users have access to this installation and operating manual 

at all times

2.6  Personnel groups

Only qualified persons may install and operate the Isomix-F 
and carry out maintenance work.

Operators

Operators are deemed to be qualified if they have read these 
operating instructions and understood the potential hazards 
associated with improper behavior.

Fitters/commissioning engineers

Fitters/commissioning engineers are in a position to carry out 
work on the Isomix-F, taking into consideration the applicable 
standards, provisions, regulations and laws and their tech-
nical training and technical knowledge, and can detect and 
prevent potential hazards.

2.7  Information on the operating environment

Corrosion and chemical and physical reactions can damage 
the control station.

The system planner is responsible for evaluating these 
parameters and developing remedies�
