ADD WATER AND SALT TO THE SALT
STOR AGE TANK
1. Using a container, add about three gallons of clean
water into the salt storage tank.
2. Add salt to the storage tank. Use salt which indi-
cates it complies with European Standard "EN 973".
INSTALL AND PLUG IN THE POWER SUPPLY
During installation, the water softener wiring may be
moved or jostled from place. Check to be sure all
leadwire connectors are secure on the back of the
electronic board and be sure all wiring is away from
the valve gear and motor area, which rotates during
recharges.
1. Remove the power supply from its packaging and
snap the appropriate modular plug (Europe or UK)
into place.
2. At the other end of the wires are two small connec-
tors. Plug these into the power wire harness com-
ing from the back of the electronic control board
(See Schematic on Page 22).
3. Plug the power supply into an electrical outlet that is
not controlled by a switch and is approved by local
codes. The unit works on 24V DC. Do not connect
without the power supply.

PROGRAM THE CONTROLLER

1. Install the softener's top cover and salt lid.
2. Complete the programming steps on Page 10.

SANITIZE THE WATER SOFTENER /
SANITIZE AFTER SERVICE
Care is taken at the factory to keep your unit clean and
sanitary. Materials used to make the unit will not infect
or contaminate your water supply, and will not cause
bacteria to form or grow. However, during shipping,
storage, installation and operation, bacteria could get
into the unit. For this reason, sanitizing as follows is
suggested* when installing.
1. Slide open the salt lid, remove the brinewell cover
and pour about 90 ml (6 tablespoons) of household
bleach into the softener brinewell. Replace the
brinewell cover.
2 Make sure the bypass valve(s) is in the "service"
(open) position.
3 Start a recharge: Press the RECHARGE button and
hold for 3 seconds, until "Recharge Now" begins to
flash in the display. This recharge draws the sanitiz-
ing bleach into and through the water softener. Any
air remaining in the unit is purged to the drain.
4. After the recharge has completed, fully open a cold
water faucet, downstream from the softener, and
allow 190 liters of water to pass through the system.
This should take at least 20 minutes. Close the
faucet.
*
Recommended by the Water Quality Association. On some
water supplies, the unit may need periodic disinfecting.

RESTART THE WATER HEATER

1. Turn on the electricity or fuel supply to the water
heater and relight the pilot, if applicable.
NOTE: The water heater is filled with hard water and,
as hot water is used, it refills with conditioned
water. In a few days, the hot water will be fully
conditioned. To have fully conditioned hot
water immediately, wait until the initial recharge
(previous step) is over. Then, drain the water
heater (following instructions for water heater)
until water runs cold.
