5.2 Installation steps
5.2.1 Feed water connection
» Install a shut-off valve
» Connect the feed water inlet to the
system. The diameter of the raw
water pipe must be at least equal to
the diameter of the connection
piece.
» Observe the information in the tech-
nical data.
WL- ROL-160/-320 WL-ROL-460 - 1200
5.2.2 Permeate pipe connection
» The diameter of the permeat pipe
must be at least equal to the diame-
ter of the connection piece.
» Connect the permeate pipe to the
corresponding connection piece and
then connect the pipe (not included
in the delivery) to the expansion tank
or return pump tank.
» Note the information in the technical
data.
WL-ROL-160/-320 WL-ROL-460 - 1200
Do never operate the unit with the permeate
line closed!
5.2.3 Connection of the expansion
vessel
» Mount the holder* of the expansion
tank on a stable wall or ensure a
secure stand on the floor.
» If necessary, connect the connection
set to the expansion vessel
» Connect the permeate line.
• Install the reverse osmosis unit as
close as possible to the consumer /
humidifier.
The maximum distance (4) is
15 metres (up to WL-ROL600)
25 metres (WL-ROL1000/1200)
•
The reverse osmosis unit (1) must be
installed at the same height of the
humidifier (3) and the expansion tank.
• The number of fittings in the pipe should
be kept to a minimum. The use of angle
joints, T-pieces and reducers increases
the pressure losses in the pipe. The
diameters shown in the tables provide
for a few fittings; if the number of fittings
is doubled, the pipe with the next larger
diameter must be used.
