Mounting
First of all, plan the installation!
The skin fi tting is to be mounted in the hull instead of existing fi tting for
the galley sink waste water. The hole in the hull shall have a diameter of
60 mm (2½”). When an existing skin fi tting is to be replaced, it is taken
away by the following method. Place a wooden plug in the fi tting from
outside, use a 60 mm (2½”) hole saw with a centre drill and cut out the
complete skin fi tting at the same time as the new hole is made. Put
through the connecting pipes and the fi tting from the outside, seal
carefully using Sikafl ex 291 or equivalent. The skin fi tting has a 32 mm
wrench grip on the inside part for easy tightening of the counter nut.
Bend aside the connection pipes to allow the 1¼” ball valve to be mounted,
which on the galley sink side shall have a hose serrated tail ø38 mm (1½”)
hose to be installed. As an option, there is a kit available, consisting of
a 1¼ ball valve, ø38 mm (1½”) hose adaptor and modifi cation kit for the
sink hose connection.
Part no. SFD 00008 AA.
Remember to use twin hose clamps below the water line level.
The compressor unit is most likely to be placed in the compartment
below the sink, in a suitable distance from the skin fi tting, not more
than one meter (3 ft.). The compressor shall be mounted horizontally.
The bracket allows a choice of mounting positions, standing or
bulkhead mounting. The compressor needs to be protected from
splashed water or water leaking from the sink at all times.
