Product features
Non-conformity / defect
Motors
Electrical system: must be performed by an authorised electrician who must issue a certificate of conformity for the
electrical system.
The system must have an adequate level of protection since it is installed outdoors. An authorised electrician is able to properly
configure the system and select the suitable components (proper IP rating).
Any drops in voltage or radio interference can cause loss of the limit switches to the motors.
In this case it is necessary to reprogram the motor as indicated in the relevant motor manual.
Any noise should not be considered as a relevant hazard, according to the health and safety requirements relating to the
machinery.
Stainless steel
The stainless steel components do not require special maintenance. The appearance of micro-oxidation, more
frequent in maritime environments subject to salt spray, does not affect the quality and durability of the product. Such
oxidation is normal. If you need to eliminate these oxidised spots you can use a steel wool or a brush with stainless steel
bristles. The protective chromium oxide film (self-passivation) will be restored naturally just through exposure to air, without
any intervention by the user.
Aluminium
The presence of marks and scratches is considered as a defect only if they are visible at a distance of 2 metres.
If the marks and/or dents are visible at a distance of 2 metres it is
considered as a defect.
Painting
Orange peel: the surface of the coating film is uneven and looks
like an orange peel.
Blistering: bulges on the surface of the coating film of various
sizes and frequency.
Sagging of the outer layer: irregular accumulations of paint
localised and well defined in the form of shallow, rounded edges
affecting the outer layer.
Flaking - Peeling: the coating film detaches from the underlying
support in the form of small flakes.
Porosity - Pitting: small holes similar to craters or indentations in
the surface of the film, ranging in size from small pin-holes up to
diameters of 1 cm.
Impurities in the outer and inner layers: the paint film has a rough
and uneven surface, easily perceptible to the touch.
Paint chips due to interference: the paint film has damage and
lesions of different depth and extent depending on the cause.
