vetus® No-Smell Filter model NSF16, 19, 25, 38
Introduction
Unpleasant smells can escape from
the ventilation openings of a toilet
tank or diesel fuel tank.
This can be prevented by fitting an
Active Charcoal Filter in the venti-
lation opening.
The Vetus No-Smell Filter contains
a PUR-foam filter element impreg-
nated with active charcoal.
Atoms of active charcoal attract
molecules from the gas as it flows
past. The extent of this attraction
depends on the molecular structure
of the gasses. Different gas mole-
cules are attracted to a different
extent. In this way, it is possible to
separate specific
gasses out from a gas mixture.
Warning
When fitting the Filter to a toilet
tank:
The filter creates extra resistance in
the vent line. During the suction
emptying of a toilet tank by a suc-
tion pump on the dock wall, it is
possible that insufficient air can
flow through to the tank via the vent
line and filter. Do take this into
account, to prevent the tank col-
lapsing.
Installation
For examples of installation see
Drawings 1 and 2.
Install the filter in a dry, cool and
easily accessible place above the
waterline. The filter element must
remain dry to ensure effective oper-
ation. Take this into account when
choosing a position.
Fit the filter high enough so that no
fluid or foam can enter the filter.
Check the maximum height of fluid
in the toilet tank, and the possibility
of foam in the diesel fuel tank, and
also water from outside.
With a sailing boat, take into
account sailing when heeled over.
Fit the filter against a vertical bulk-
head.
Connections
The filter connections are suitable
for hoses of 16, 19, 25 or 38 mm
diameter, respectively.
Always use flexible hose for both
connections.
Use only water and/or soap (never
use grease or products containing
oil) to simplify connecting the hose
to the connectors.
Fit a hose connection with one
stainless steel hose clamp.
Vent line
Always install a vent line sloping
down from the filter to the tank. Fit
the flexible vent line (hose) using
sufficient brackets to prevent sag-
ging or the creation of a siphon -
see Drawings 3 and 4.
If necessary, use rigid metal or plas-
tic pipes to cover large distances,
always connect the rigid pipe to the
tank and No-Smell Filter with short
lengths of flexible hose.

Maintenance
Replace the filter element at least
once a year at the start of the sail-
ing season.
Always replace the filter if liquid or
foam has entered it. Unscrew the
cap - see Drawing 5.
Take the 8 loose filter element discs
one by one from the housing. Clean
the filter housing if dirt or algen
growth is present. Put in the new fil-
ter discs one by one. Lubricate the
O-ring and screw thread with sili-
con oil or Teflon spray - see
Drawing 6, and refit the cap.
N.B.: Always remove and refit the
screw cap by hand only, never use
tools for this, see Drawings 7 and 8.
Every year, check to see that the
vent line has not been blocked or
damaged. Also check the vent line
fittings, see 'Installation, Air Vent
line'.
