Fitting, general
N.B.: The highest permitted design category
and the highest permitted application is stated
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 hazard-
ous to lungs and eyes. So always wear a
dust mask and goggles when working
with this material. Ventilate the working
area well.

Fitting
The porthole can be fitted in a surface with a
minimum thickness of 3 mm. and a maximum
thickness of 18 mm.
• Draw the hole to be cut out using the port-
hole frame, for the main dimensions, see
page 14.
• Cut the hole in the ship by sawing in poly-
ester, aluminium or wood, or by acetylene
cutting for steel.
• Remove all burrs carefully and smooth the
edges.
• These portholes have a clamp profile; fixing
holes in the side of the ship are NOT neces-
sary.

Apply a sufficient amount of sealant to en-
sure a good seal, see Drawing 1, (1) = Sealant.
• Position the hatch in the hole.
Fixing Screws:
Use Stainless Steel countersunk head screws
M5 in accordance with DIN966. Choose a screw
length related to the wall thickness, see Table
in Drawing 1.
A= Clamp Reach, L=-Screw Length.
• Fit screws and tighten securely.

Operating
Opening:
Turn the clamps half a turn to the left and pull
on the clamps to open the window. The win-
dow will remain open in any position because
of its clamp hinge.
Closing:
Ensure that the clamps are in the 'open' posi-
tion. Push the window closed and turn the
clamps half a turn to the right.

Maintenance
Re-adjusting hinges:
Re-adjust the hinges when the porthole no
longer remains open. See Drawing 2.
The clamp cannot be adjusted.
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.
