Installation and Operating Instructions
Congratulations
You have chosen a product from Helios Ventilation Systems. This means that you have purchased a premium product and you will benefit from our many years
of experience. All KWL EC 200/300 W R/L units have been tested at every stage of production. Not only has the obvious function (e.g. the fans running) been
tested, but also the functions which you, as the customer, cannot test. For example, these include internal and external leakages and electrical safety. We
enable you to reduce operating costs through innovative ideas in the field of control and feedback control systems.
However, if you unexpectedly have a problem with our unit, you can contact the specialist installer or our Helios customer service team.
