Fitting, general
N.B.: The highest permitted design category and the highest permitted application is stat-
ed on every porthole.
When fitting the porthole, take the following into account:
- A porthole must always open inward.
- When fitted in area 1 on sailing or motor ships within design category A or B, no part of
the porthole should protrude beyond the hull.
- Only fit in a completely flat hull section! The porthole will never be watertight when
closed if fitted in a curved surface!
Dust released when cutting and sanding glass-fibre reinforced polyester is haz-
ardous to lungs and eyes. So always wear a dust mask and goggles when working
with this material. Ventilate the working area well.

Maintenance, general

Stainless steel can be cleaned with a 'metal cleaner'.
After cleaning, apply a thin coat of transparent wax for protection.
Protect the sealing rubbers with talcum powder.
