Frequently Asked Questions

Q: Who is allowed to install or repair the Ultraheat?

Only competent, trained personnel (experts) who understand the technical rules and relevant standards are allowed to install and repair the unit. Electrical connections must always be carried out by a qualified electrician.

Q: Can the Ultraheat be installed if the S-heater is located beneath water-bearing parts?

No. If the S-heater is installed below water-bearing parts such as a sink or shower, installation of the Ultraheat is strictly forbidden due to the risk of electric shock if water enters the control unit.

Q: What should be done when re-connecting the exhaust duct during installation?

It is essential to install a new form ring (included in the Ultraheat delivery) when mounting the exhaust cowl/exhaust duct to prevent exhaust gas leaks inside the vehicle.
