THE INTERCHANGEABLE PORT SYSTEM
For your SUBAL housing, there is a wide range of front ports available, the largest of all
manufacturers. This allows you the use of a multitude of regular lenses under water, ranging from
fisheye lenses, extreme wide angle-lenses, zooming lenses and macro lenses up to the 200 mm lens.
The port O-ring
Please pay attention to all that is advised in chapter
USE AND MAINTAINANCE OF O-RINGS
!
Be sure that the O-ring and the sealing surface is clean and lightly lubricated
.
The SUBAL ND7100 with port size 4 provides a port locking system (not available on housings with
port size 3! ).
Turn this lever downwards to release the port lock. After mounting the port turn the lever back to the
Lock position.
Inserting of the frontport
SUBAL-frontports are attached to the housing by a bayonet mount.
Insert the port (after checking as described above) into the housings bayonet with the white dot or the
SUBAL-logo pointing towards the front main dial control knob.
While pushing in
, turn the port 90 ° clockwise until it stops. If properly installed, the white dot or the
SUBAL-logo is aligned with the middle of the housing.
Most important: After installing check thoroughly that the O-ring is seated correctly in its
groove and does not protrude from the housing.
To remove the port turn counter-clockwise until it stops and then turn back a little bit.
Do not change the port if it is very warm (eg. through irradiation from the sun, etc.)!
Synthetic material from which the ports are made expand more than the aluminium housing body and
may therefore jam in the mounting.
When travelling by aircraft the frontport should be left mounted to the housing ONLY if the port
O-ring and/or the body O-ring is removed.
