Vetus Magnus Manuel D'utilisation page 4

Introduction
This Manual applies to the following Vetus Hatches type:
- Magnus
- Altus
For drawings see pages 13-14.
Operation
Locking/unlocking:
All Vetus hatches are fitted with one or more unique locking
handle. With this ergonomically designed handle the last 10
degrees of turning the handle will lock the hatch. A red dot
indicates that the handle is unlocked. When the handle is fully
locked a white dot is visible. See drawing 1
1. Handle closed and locked,
2. Handle closed and not locked,
3. Red dot indicating unlocked.
Opening:
Turn the handle(s) quarter of a turn and push the hatch open.
The handles can also be opened from the outside if unlocked.
Magnus hatches are fitted with friction hinges and will stay open
to any position. Altus hatches are fitted with telescopic friction
stay(s) which can be tightened to hold the hatch open in any
position.
For Altus hatches make sure the friction stays are loosened and
free to move before opening or closing the hatch, or damage
may be done to the hatch.
Ventilation:
All Magnus and Altus hatches can be closed, and locked in
either the ventilation position or fully closed position. See draw-
ing 2. For hatches with four or more handles, only use the han-
dles opposite the hinge when in ventilation position.
Closing:
Ensure that the handles are in the 'open' position. Pull the hatch
closed, turn the handles a quarter of a turn and lock them. See
Drawing 1 (1).
For Altus hatches make sure the friction stays are loosened and
free to move, or damage may be done to the hatch.
Magnus hatches are fitted with a positive rubber seal to ensure
maximum water tightness. Initial closing of the hatch after instal-
lation may require assistance from the outside of vessel. Once
the hatch has been closed for the first time the seal will set and
allow trouble free operation of the hatch.

Safety
Escape hatch handles must be unlocked when sailing. See
Drawing 1 (3).
Fitting
N.B.: The highest permitted design category or the highest per-
mitted area of use is stated on every hatch.
When fitting the hatch, take the following into account:
- The hatch must open outward.
- Fit the hatch on a completely flat surface! The hatch will never
be watertight when closed if fitted on a curved surface!
First, fill out the curved surface with a close-fitting wood
frame.
- It is not possible to check that the hatch is watertight until it
has been completely built into the ship.
- When the hatch has not been fitted in the ship, the opening
and closing of the hatch can damage the aluminium frame
and/or hinges when the hinges have been adjusted very
tight!
- Even when the hatch has been built in, the hinges should not
be adjusted too tightly; this could damage the frame and/or
hinge, so that a good seal can no longer be guaranteed.
1. Draw the hole to be cut out using the hatch deck frame.
• All Vetus hatches are manufactured with a corner cutout
radius of 43mm
• Cut the hole in the ship by sawing for polyester, aluminium
or wood, or by acetylene cutting for steel. Remove all
burrs carefully and smooth the edges.
Dust released when cutting and sanding glass-fibre rein-
forced polyester is hazardous to lungs and eyes. So always
wear a dust mask and goggles when working with this
material. Ventilate the working area well.
2. Position the hatch over the cut hole and mark the fixing holes
for the frame, see Drawing 4. Drill the holes and remove any
burrs.
• Removal of friction stay mount will allow hatch to open
fully for installation. See figure 3.
3. Apply a sufficient amount of sealant to ensure a good seal,
see Drawing 5. Position the hatch on deck.
• Fixing the frame to the deck - deck material:
- Magnus hatches are fitting with a transport screw fixing
the hinge to the deck frame. This must be removed prior
to fitting to the vessel and replaced with positive fixing to
the deck. See drawing 6(1).
