Operating instructions

 In each case, the heat transfer liquids cover a specific tem-
perature range. This temperature range must match the tem-
perature range of your application.
 The use of heat transfer liquids can cause hazards from high or
low temperatures and fire if certain temperature thresholds are
exceeded or undercut or if the container breaks and there is a
reaction with the heat transfer liquid .
The heat transfer liquid safety data sheet specifies all possible
hazards and appropriate safety measures for handling the
liquid. The safety data sheet must therefore be consulted for
the intended use of the device.
1.6 Materials
All parts coming into contact with the heat transfer liquid are made
of high quality materials suitable for the operating temperature.
High quality stainless steel and temperature-resistant plastics are
used.
1.7 Hoses
Only LAUDA hoses are permitted to be used for the external
hydraulics circuit. LAUDA hoses are hoses approved by the com-
pany LAUDA DR. R. WOBSER GMBH & CO. KG. When selecting
suitable hoses for the application, the permissible temperature
range and the maximum permissible pressure must be particularly
observed.
1.8 Application area
The device is exclusively permitted to be used in the following
areas.
 Commercial area
 Indoor use
Outdoor installation is also possible with appropriate options.
 At altitudes of up to 2,000 m
 Ambient temperatures from 5 to 40 °C
 Maximum relative air humidity
80 % for temperatures up to
31 °C, decreasing linearly to 50 % relative air humidity at 40 °C
 Mains voltage fluctuations up to +/- 10 % of the rated voltage
 Transient surge voltages up to the values of overvoltage cate-
gory II
 Temporary surge voltages that occur in the mains power
supply
 Contamination level 2
 IP protection class IP 32
