REMOVING THE FRONT HOUSING COVER
The front housing cover can be removed by unscrewing the cover anti-clockwise
from the housing (thread length approx 10mm) see Fig. 3. To avoid damage to
the halogen bulb, pull the front cover straight away from the housing.
CLOSING THE HOUSING
Before closing the housing, all threads, sealing surfaces and seals must be
checked for integrity and cleanliness. Should the sealing surfaces and/or
components be contaminated, then the O-rings (40 x 3,0 50° hardness and
48 x 1,6 50° hardness) and its groove should be th oroughly cleaned. Should the
sealing surfaces and/or components be damaged, then all damaged parts should
be replaced. If the O-ring is removed, care must be taken not to damage the
groove in which the O-ring sits. A soft blunt tool should be used for the removal of
the O-ring, i.e. a wooden tooth pick. Before the components are refitted it is
recommended that a thin coating of silicone grease is applied as lubrication. It is
recommended that after such work has been carried out, that the seal/integrity of
the housing is first checked underwater without the power pack fitted. The
housing is then closed by screwing the components clockwise together. The
screw fitting should be tightened by hand only until the parts are mated together.
MAINTENANCE OF THE REFLECTOR
If the reflector mirror becomes dirty or is contaminated, it must be cleaned with a
soft, dry cloth. Remove the front housing cover and then the reflector can be
removed. First remove the O-ring (
∅
3mm, 50° hardness) using a blunt tool such
as a tooth pick or similar, care must be taken not to damage the O-ring. Once the
reflector has been cleaned, the O-ring can be refitted into the groove between the
reflector and the housing cover, make sure the O-ring sits correctly into the
groove, a blunt tool can be used for pressing the O-ring into the groove.
