Safety instructions
1. Safety instructions
1.1 General
This technical documentation contains basic instructions
that must be observed during set-up, operation and mainte-
nance. Therefore it is essential that it is read before assembly
and commissioning by the installer as well as by the respon-
sible technical personnel/operators. It must always be availa-
ble in the location where the system is in use.
The general safety instructions listed in the “Safety instruc-
tions” section must be followed, as must the special safety
instructions and warnings that appear in other sections.
Moreover, the special rules and guidelines for accident preven-
tion that apply to the location of use must also be followed.
Instructions and warnings affixed directly to the system,
such as arrows indicating the direction of rotation or labels
for fluid connections, must always be followed and kept in
a completely legible condition.
1.2 Personnel qualification and training
The personnel carrying out operation, maintenance, inspec-
tion, and assembly work must have appropriate qualifi-
cations. The responsibility, competence, and supervision
of personnel must be regulated in detail by the operator.
If personnel do not have the required skills, they must be
trained and instructed. If necessary, this may be provided
by the manufacturer/supplier at the request of the system
operator. Furthermore, the operator must ensure that the
content of the technical documentation is completely un-
derstood by personnel.
1.3 Hazards due to failure to follow safety instructions
Failure to follow the safety instructions can lead to hazards
to personnel as well as to the environment and the system.
Failure to follow the safety instructions can result in any
damage compensation claim being void.
Specifically, failure to follow the safety instructions can
result in the following hazards, for example:
n Failure of important system functions
n Failure of specified maintenance and repair methods
n Hazards to personnel due to mechanical effects
1.4 Safe working practices
The safety instructions listed in this technical documentation,
applicable national guidelines for accident prevention, and any
workplace, operating, and safety guidelines provided by the
operator must all be followed.
1.5 Safety instructions for maintenance, inspection, and assem-
bly work
The operator must ensure that all maintenance, inspection,
and assembly work is carried out by authorised, qualified
technicians who have sufficiently informed themselves by
studying the technical documentation in detail.
As a matter of principle, work on the system must only be
carried out when it is switched off.
Immediately after completion of work, all safety and protec-
tive systems must be reattached and/or reactivated.
Before recommissioning the machine, the points listed in the
section “Commissioning” must be followed.
1. 6 Unauthorised modification and replacement parts
Modification of or changes to the system are only permitted
after consultation with the manufacturer. Original replace-
ment parts and manufacturer-authorised accessories are
important for your safety. The use of other parts can void
liability for any resulting consequences.
1.7 Unauthorised operation
The operational safety of the system provided can only be
guaranteed if it is used as intended. The limit values speci-
fied in the technical data must not be exceeded under any
circumstances.
These instructions provide important information on how to
handle the system correctly. Failure to observe these instruc-
tions can lead to faults in the system or problems in the sur-
rounding environment.

4.2. Safety notes
Make sure you have all the necessary tools to hand before
starting the installation.
Observe the respective applicable legal regulations.
Carefully read this manual. If you have any further questions or
comments, please contact a representative of Condair GmbH.
Check the inlet pressure:
Minimum 1 bar (dynamic), maximum 8 bar (static) (15–116 PSI).
If required, reduce the inlet pressure.
Do not install the Condair Soft 10 near a heat source. The
ambient temperature must be below 50°C. Protect the
softener and the connecting pipes from frost.
Make sure you have the latest installation manual. If necessary,
clarify this with a representative of Condair GmbH.
4.3 Installation
1. Close the water supply line and make sure that the pres-
sure has been released from the pipeline.
2. Connect the two softener connecting pipes (see fig. 1)
with the corresponding quick couplings.
The quick couplings are colour-coded in the figure (red to
red, blue to blue)!
Fig. 1
3. Connect the two connections provided for the drain
(see fig. 2) with the waste water hose (Ø 13 mm) included in
the scope of delivery.
The drain must be frost and heat resistant (min. 5°C,
max. 50°C).
Fig. 2
Caution:
Do not forget to install the overflow supplied.
Drill a hole (Ø 16 mm) in the side wall of the container,
10 cm from the top edge of the container.
Install the overflow, using the supplied screw nut.
Remove drilled out material (plastic chippings) from the
container.
Connect the overflow with the waste water pipe.

4. Connect the softener with the brine valve. To do this, use a
4 mm pipe to connect the T-piece that joins the two units to
the brine valve. Insert the pipes as far as possible (limit stop)
into the quick couplings. Avoid any blockages and kinks!
5. Insert the unit with the brine valve (make sure the direction
is correct) into the container so that the connections fit in the
designated recess at the back of the container. The brine valve
must be on the bottom of the container.
6. Now connect the water inlet and outlet of the Condair
Soft 10 to the water lines using the enclosed adapters /
direct connections. Ensure that the filter insert is inserted
correctly in the water inlet.

Hardness regulator — Dilution control
5. Settings
5.1 Hardness regulator
Measure the hardness of the incoming water by means of
a hardness test. Here, ppm settings of CaCO3are specified
(10 ppm CaCO3= 0.56°dH).
Now adjust the hardness regulator until the correct setting
is reached. A 5mm Allen key is needed for this.
5.2 Blendind device
Using the 5 mm Allen key, set the dilution control to the
0 position.

6. Commissioning
1. Slowly open the main valve.
2. Fill the salt into the salt container provided. Use only salt
tablets specifically designed for softeners (e.g. regenerating
salt 25 kg — SAP No. 2001753).
3. Add water to the salt container until the water level is
about 10 cm.
The float of the brine valve must float up.
4. Open a tap downstream of the softener (consumer).
Some air may escape from the tap. This air comes from
the softener. This release of air is a one-time occurrence
(only during commissioning).
As soon as only water (and no air) flows out of the tap or
consumer, close it again.
5. Perform a manual regeneration.
n Select one of the two units for manual regeneration.
Use a 5 mm Allen key to turn the programme disc (PRG)
manually.
n Turn the PRG disc anticlockwise to the position indicated
in fig. 2. When the arrow and the line on the transparent
lid reach the area of the letter “B” (brining, i.e. salinating),
regeneration is started. The disc drops down slightly at
this moment (this can be seen and heard). “R” stands for
refill (refill the container with water after regeneration).
To check that the softener is in regeneration mode, there
should be a small water flow at the drain and the water
level in the salt container should drop slightly.
Fig. 2
n Allow the regeneration to run until it stops automat-
ically. This is likely to last approximately 12 minutes.
When there is no more water flow at the drain, regen-
eration is finished.
n Open a tap (consumer) downstream of the softener and
flush for several minutes to let the remaining hard water
run out of the pipes.
n Check the hardness of the outlet (< 1°dH) by means of a
hardness test (not included in the scope of delivery).

6. Now place the protective cover and the lid on the contain-
er: first the protective cover over the appliance (1), then the
lid over the front part (2).
To refill salt at a later stage, simply remove the lid of the
front part.
Drill a hole for the drain hose to the drain. Select the most
suitable location for this, depending on where the drain is in-
stalled. This hole must NOT be below the hole of the overflow.
Connect the overflow with the drain.
NOTE:
It is recommended to have the water softener installed by
a professional. Although this softener is probably the simplest
and safest softener on the market, it is essential to take all
necessary precautions and follow the applicable regulations.
This installation manual has been written to assist
a professional installer, assuming that this person has
the necessary knowledge of hydraulic softeners as well as
domestic installations.
Proper installation is a prerequisite for faultless operation.
Annual inspection of your Condair Soft 10 water softener is
particularly important because it guarantees you optimum
performance and a long service life of the appliance.
