D Safety Information
VAHEAT was designed according to international regulatory design and safety
standards as declared on the device and in this manual. These standards are
only met, if VAHEAT is used following this manual.
Only use the procedures, controls and adjustments described within
this manual. By doing otherwise, damage to the device or even a
hazard to you and your surrounding may arise.
• Read the manual before setting VAHEAT up and operating it.
• Ensure that this manual is available to every person operating VAHEAT.
• None of the individual parts should be opened or modified. There are no
serviceable parts inside. Refer repair to authorized personnel only. Opening
voids warranty.
• System must be grounded. Only use VAHEAT in combination with the
provided power supply unit.
• Use only accessories supplied by INTERHERENCE or your local
representative. Doing otherwise might damage the device or will even put
you and your surrounding into danger.
• Use only cleaning procedures and materials described within this manual.
• Contact INTERHERENCE or your local representative if you have any
uncertainty in handling VAHEAT.
VAHEAT is a highly sensitive laboratory device designed for indoor use.
Compliance with applicable safety regulation (IEC, CE, FCC) is only ensured
when operating VAHEAT under conditions as specified in this manual.
If VAHEAT was exposed to inappropriate environmental conditions such as
excessive heat, moisture, or mechanical shock etc. check for any apparent
changes of the device in color, shape, or mechanical function before operating
it. If you find any change, stop using the device, prevent others from using it
and contact INTERHERENCE GmbH or your authorized representative for
repair.

E WEEE Compliance
INTERHERENCE GmbH is a registered supplier according to the Waste
Electrical and Electronic Equipment (WEEE) Directive 2012/19/EU. The
crossed-out waste bin symbol on the control unit indicates that this electrical
or electronical device must be collected separately and should not be mixed
with the regular waste or on a public waste disposal site. The specifics for
collection of electrical and electronic waste vary in each EU country. Reuse,
recycling and other forms of recovery are encouraged to reduce the negative
impact on the environment. INTERHERENCE will help you upon request to
find the correct way to dispose our products. Potential negative effects on
human health and the environment could arise from inappropriate waste
handling. Please be advised that it is the responsibility of the customer to
delete any personal data that may be stored on the device.
Figure 1 WEEE symbol according to directive 2012/19/EU.
INTERHERENCE and its distribution partners offer compliant with the Waste
Electrical and Electronic Equipment (WEEE) Directive for all end users in the
European Union the option to return defect or ‘end of life’ VAHEAT systems
for disposal exempt from charges. This service holds true for parts that fulfill
the following:
• marked with the crossed-out waste bin according to Figure 1
• sold to a company or institute within the EC
• currently owned by a company or institute within the EC
• still complete, not disassembled, and not contaminated.
As the WEEE directive applies to self-contained operational electrical and
electronic products, this "end of life" take back service does not refer to
other INTERHERENCE products, such as
• components,
• mechanics
• left over parts of units disassembled by the user
• disposables (e.g. smart substrates)
