2. Soft water towards the house.
3. Drain tube.
4. Untreated water.
5. Overflow line.
6. Sediments pre-filter.
ATTENTION: this configuration is a typical insta-
llation for KUBE. Your installation may differ. Ins-
tall a pressure regulating valve and a check valve,
when necessary, in the water supply of the softener.
The by-pass may be installed with connections either
upwards or downwards, whilst respecting the inlet and
outlet connections towards the head, which have em-
bossed marks.
1. The system must always be installed with the supplied
by-pass valve. Additionally, a three-valve by-pass can
be installed.
2. Close the general water supply valve which should be
next to the main pump or the water-meter.
3. Open all taps in order to empty the pipes from all
water.
Note: Make sure that the heater is not emptied, in order
to prevent any damage.
DANGER: there is a danger of injury due to an ex-
cess of weight. It is necessary that at least two
people move and install the syste, as well as move and
rise the salt bags. TAhere is a danger of back injuries
and other body injuries.
4. Move the water softener towards the installation
location. Place it on an even surface. If necessary,
place it on a plywood platform with a minimum
thickness using a wedge.
ATTENTION: no not place the wedges directly
undernearth the salt tank.The weightof the tank
filled with water and salt may cause the tank to
break against the wedge.
5. First make a visual check and clean the inlet and out
let connections of the softener to remove any residues.
6. Assemble the by-pass in the body of the valve by pre-
viously lubricating all joints with the lubricant supplied.
7. The tubes and accessories used to connect the main
supply pipe to the inlet and outlet of the water softe-
ner valve must be lossely measured, cut and assembled.
Please keep all fastenings, joints and tubes centred and
straight. Check that water flows from the pipe towards
the inlet of the water softener.
Once the installation of all pipes is finished and before
connecting the by-pass, let water flow through the inlet
and outlet pipes to remove all residues and check the
tightness of the installation.
ATTENTION: the inlet and outlet are indicated in
the valve. Draw the sense of the flow to be sure.
ATTENTION: check that the pipes are fixed, alieg-
ned and supported in order to avoid any pressu-
re on the inlet and outlet of the water softener. A
wrong pressure coming from a misaligned pipe, or not
supported, could damage the valve.
WELDED COOPER
1. Clean carefully and apply welding paste on all joints.
2. Carry out all the weldings.
ATTENTION: do not weld to the installation the pi-
pes of the by-pass valve. The heat from the wel-
ding could damage the valve.

THREADED PIPE
1. Apply a sealing paste for pipes or Teflon tape on all
male threaded pipes.
2. Tighten all threaded connections.
CPVC PLASTIC PIPE
1. Clean, preapre and glue all joints according to the
manufacturer's drinking water.

approved for drinking water.
6.1. BRINE VALVE ASSEMBLY (ONLY KUBE 6)
In the KUBE I systems, the brine valve is supplied unas-
sembled, so it must be installed before the softener
final installation.
1. Remove the resin tank from the softener cabinet.
