2. Precautions:

 Make sure you have all necessary tools on hand before you begin

with the installation.

 Follow all local legal regulations.
 Read this manual carefully. If you have any questions or

remarks, please contact your Delta supplier.

 Check incoming pressure: minimum 1 bar (dynamic), maximum 8

bar (static) (15 PSI- 116 PSI). If necessary reduce incoming
pressure.

 Do not install the Delta Softener close to a heating source

(environment temperature must be below 50°C).

 Protect softener and drain (12) against frost.
 Make sure you have the latest installation manual at hand. Check

with your Delta supplier.

3. Installation:

3.1 Close main valve and make sure pressure is released from piping.

This can be done by opening at least one tap.

3.2 Cut open main water supply in order to install direct connections to

the Delta Softener or to install the Delta Bypass (recommended).
Follow the arrows on both Bypass and softener for water inlet and
outlet.

Pay attention that the inlet filter doesn’t fall out.

3.2.1

with Delta Bypass with direct connections

The Delta Bypass has a ¾” connection. The direct connections on
the water softener are available in ½”, ¾” and 1”.

Caution: before installing the

softener, set the Bypass in “bypass”
mode, not in “service”.

3.2.2

Connect elbow or straight outlet (#12) to a local drain by means of
a 13mm flexible drain pipe as supplied by your local supplier. In
order to guarantee that the device will keep on functioning perfectly
in the future, this drain pipe should be spirally reinforced to avoid
later blocking and/or kinks. Please protect the drain against frost
and heat (min. temp. 5°C, max. temp. 50°C).

3.2.3

Connect the brine valve (#5) to the softener by means of a Ø4mm
flexible tube. Insert the tube as far as possible (to stop) into the
quick-release couplings. Make sure not to squeeze the tube; avoid
kinks.

Make sure to install the supplied overflow tap. First, pierce a hole
(Ø21mm) in the side wall of the salt bin. The location of the hole is not
important, make sure however that it is approx. 10cm down from the top
edge of the salt bin. Once the hole has been drilled, mount the overflow
tap and secure it with the supplied nut. After drilling, remove all bits of
plastic that have fallen into the salt bin. A separate instruction leaflet with
detailed information has been added to the device.
