9. Maintenance

The correct maintenance of the heater is important to achieve the full service life of the
product, ensure the best performance and avoid related risks.
The following advises should be taken into consideration before using the product:
• Check that there are no damages in the housing.
• Check that there are no damages in the insulation of the cable and in the plug.
If so, replace them.
• Check that the lamination of the yoke is not broken. If the delamination get's too much,
then replace the yoke with a new one to avoid extreme noise and eficiency losses.
• Check that the yoke is in good contact with the U-shaped core. The contact area should
be clean and rust-free. There should not be air gaps between the surfaces. Non-parallel
surfaces might generate vibrations and loud noises and cause eficiency losses.
• Check that the closing system (if any, sliding rails or swiveling hinge) is not damaged.
• Check that the temperature probe, cable and plug are clean and not broken. Otherwise
the temperature reading and control might not work properly.
When required and at regular intervals:
• Clean the heater using only a clean dry cloth.
• Clean the contact surfaces in between the yoke and the U-shape core. Add a layer
of LGAF 3E anti-fretting paste to protect the surface area. This will help to keep the
surfaces rust-free, reduce the heater noise and maintain heater eficiency.
• Adjust the closing swivel system if required by using the screws in the hinge.
