Installation Audit Form

Thetford offers an additional service by auditing the installation of its product. This means that before a Thetford product is installed a Thetford local service representative will carry out a specific audit based on the Thetford installation instructions. The audit is meant as a reference for the specific model to ensure correct installation. In any case the Thetford local service representative can be contacted for any additional support related to the installation of the product.

Serviceability

The installer of Thetford products is responsible for proper installation to ensure the correct functionality and serviceability of the appliance. In terms of serviceability, this means that a dealer or an authorized Thetford service partner must be able to de-install and re-install the Thetford products within the time that is allowed according to the Thetford time-list, using standard tools and equipment.

This is to claim any warranty during the period of 3 years after purchase date. The serviceability of the product is also included in the audit. In case of any queries on this subject, please contact the Thetford local service representative before installing the product.
