Installation of the sending unit
The sending unit must be installed in a turbulence-free zone in the hull. If an echo sounder is installed, the Sumlog sen-
ding unit should be installed at the same height and to the side of, or laterally offset to the echosounder. Check for suffi-
cient distance to stanchions, stringers, bulkheads, etc. when drilling the hull.
Do not install the sending unit close to external valves, anodes, etc. to avoid influences by turbulence.
Make a hole 39 mm dia., at a suitable location. The wall thickness can
be up to 30 mm. Camber the hole out at 45 degrees for good sealant
distribution during the assembly. To install the hull sleeve and the sen-
ding unit proceed as follows:

INSTALLATION INSTRUCTIONS: Viewline 85 mm
1. Put salt-water resistant sealant on the hull sleeve flange and intro-
duce the sleeve from the outside into the hole.
2. From the inside, install the black sealing ring on the hull sleeve,
then the white one, and screw the fixation nut down.
Lightly hand-tighten the fixation nut at first. After letting the sealant
harden, tighten the nut another ¼ turn by hand and check the hull
feedthrough for leaks.
3. Put the loop of the control rope around the hull sleeve and knot the
loose end of the rope to the blind plug.
4. Screw the flood valve to the hull sleeve until an audible click indi-
cates secure seating, is heard.
5. Insert the sending unit from the top and secure it with the nut.
Note the correct direction when inserting the sending
unit. The pointed side of the sending unit loop must be
directed towards the bow as soon as the sending unit
has been inserted.

On sailing boats the sending unit should
always be installed in front of the keel, as
close to the longitudinal ship axis as possible.
On boats with a long keel the installation
should be at the end of the first third of the
hull, but not at the widest location of the hull.
On powerboats the sending unit should be
installed at about the first third of the hull and
never towards the stern in a zone of strong
turbulence or up front, where strong distur-
bances by air induction must be expected.
An ideal installation is near the longitudinal
axis of the ship and in the zone of the first
stringer, directly in front of the engine com-
partment if possible. At higher speeds this is
the only location where a disturbancefree
operation can be expected..
