User Notes
Small "vent" hatches are restricted to 90 degree opening and should not be forced beyond their "stop" position, as damage to the lever mechanism may occur. Larger hatches are not self supporting beyond the vertical position and will fall fully open if unrestrained.
The locking ventilation position is used by closing the handles into the catch block centre slot. Care should be taken not to stand on or load the hatch lid in this position, as damage could occur to the handle or catch block.
Always wash the hatch with soap, water and a soft cloth.
Never use abrasive or solvent cleaners on the acrylic lid, as this may at a later date damage the acrylic.
To avoid risk of injury care should be taken to keep hands and limbs clear of lever and lid pinch zones while operating and adjusting the hatch.
Backing plates are available separately to offer a quick solution to through bolting the hinge units neatly.

Friction lever adjustment
The friction lever units installed on Ocean hatches are
Adjustment is made by means of the socket head screws on either side of the lever assembly.
Using a 4mm (5/32") hexagon key, turn the adjusting screw approximately 1/8th of a turn in a clockwise direction to increase the positioning force. This is most easily carried out in the fully open or closed positions.
Do not over tighten the adjusting screws
On hatches with multiple lever units, care must be taken to adjust all levers to a similar loading.
Open the hatch and check for correct operation.
Lubricants should not be used on the friction lever assemblies as this will adversely affect the function of the units.
