Operating
Opening:
Turn the clamps half a turn to the left and pull on the clamps to open the window. The
window will remain open in any position because of its clamp hinge.
Closing:
Ensure that the clamps are in the 'open' position. Push the window closed and turn the
clamps half a turn to the right.
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 porthole frame, for the main dimensions, see page
14.
Cut the hole in the ship by sawing in polyester, 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 ensure 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.
Maintenance
Re-adjusting hinges:
Re-adjust the hinges when the porthole no longer remains open. See Drawing 2.
The clamp cannot be adjusted.
