DESCRIPTION OF SIMPLIFIED ELECTRONIC TIMER 366/604
The system has a valve with a timer where all operation controls are located.
COMMISSIONING
In order to use the system in a safe way, it is fundamentally important to follow the indications of the next paragraphs, as
well as checking the protection and safety devices before each use.
IN ORDER TO START OPERATING THE SYSTEM, MAKE SURE THAT:
• The water connections are compliant with the standards;
• The electrical connections are compliant with the standards.
PROCEDURE
1. Turn on the timer and start up the forced regeneration by pushing the button .
2. Open the water supply tap.
3. Check the discharge device so that air goes out before water for 1 minute in total.
4. Close the supply tap and make the regeneration stages proceed by keeping the and buttons pushed at the same
time for 4 seconds and than release.
5. Let it continue in automatic mode until the valve returns to its initial position.
6. Fill the vat with salt, add 10L of water and operate the system by opening the supply and the output taps, closing the by-
pass.
If the water is still a bit coloured, leave it flush from the output tap until it gets clear.
OPERATING THE SOFTENER
IMPORTANT
Before operating the softener clear the air form the system and remove the resins that, at the beginning, could give a yellowish/red-
dish colour to the water.

The system has 4 dierent regeneration cycles indicated by the codes U1 – U2 – U3 – U4.
Choose the most suitable for your application according to the size of the cylinder and to the quantity of resin it contains.
IMPORTANT
The regeneration cycle is set by the manufacturer.

TIMER AND ICONS FRONTAL DESCRIPTION
DISPLAY
The display shows clearly visible 2-digit numbers.
SET UP BUTTONS
Set ups have been simplified and reduced for each function and for each single button.
MANUAL REGENERATION
It is possible to set up an additional regeneration at any time or making it start immediately by pushing the relevant button.
POSITION INDICATOR
During the regeneration process the current position is displayed.
FRONTAL CLOSING BLOCK
A special device blocks the opening of the frontal.
The buer battery, which maintains time set up in case of black out, is not present.
The system maintains the time stored for about 6 hours and then resets.
This buttons allows setting the hour, the system does not allow to set minutes.
This button allows setting the quantity of brine needed for resin regeneration.
This setting is made by the manufacturer.
This button allows setting the regeneration break.
It is possible to choose a regeneration break every 8 working hours (3 regenerations per day) up to a regeneration every 30
days.
The regeneration time of reference is 2:00 a.m.. In case of 3 regenerations per day, these will start at 2:00 a.m., 10:00 a.m.
and at 6:00 p.m., while in case of 2 regenerations per day, these will start at 2:00 a.m. and at 2:00 p.m.

STOP
The system can be stopped as follows:
TEMPORARY STOP
• Unplug the power and close the water taps.
• Disconnect the connection pipes.
• Empty the brine tank and wash it inside.
• Clean the softener and place it in a dry place, protected from the elements and with restricted access (keep it out of
children’s reach or incompetent persons).
PERMANENT STOP
Repeat the same operations as for temporary stop, then proceed to:
• Wrap the machine with cardboard, polystyrene or other materials and deliver it to the sta in charge (authorized waste
disposal or second-hand collection).
RESTART AFTER A LONG PERIOD OF INACTIVITY
• Always ask a skilled and qualified technician to ensure that the system has kept well-protected electrical equipment.
• Supply voltage to the machine connecting it to the power supply and check the timer.
• Slowly open the water input valve and start a forced regeneration.
• Introduce salt into the related container, 10 l of mild water and 50 ml common water disinfectant such as Amuchina.
• Wait till the end of regeneration (not shorter than 2 ½ hours), then open the water output valve and close the by-pass
valve.
IN CASE OF EMERGENCY/DANGER, THE SYSTEM CAN BE STOPPED AS FOLLOWS:
1. Disconnecting power supply;
2. Closing water input/output valves.
In this way you can immediately stop the system.
WARNING
Make sure water does not get inside the system during out-of-service periods in order to avoid short-circuits or malfunctioning.

SET UP
ADJUSTMENTS
IMPORTANT
During the set up procedure, if no button is pushed for 5 seconds the display will automatically show current time and the system
will set to the operating stage
IMPORTANT
This adjustment is generally made by the manufacturer, though from the time of regeneration to that of installation it could reset.
For the adjustment strictly follow the indication of the table of litres of resin contained in the machine (see table 1).


TIME ADJUSTMENT
Push the icon button until the display shows current time. The button only allows setting the hour until 11:00 p.m., than
it goes back to 00:00. The default time is 00:00.
REGENERATING QUANTITY ADJUSTMENT
REGENERATION FREQUENCY ADJUSTMENT
Push the icon button until displaying the following options:
.3 ) Regeneration frequency every 8 hours (3 times per day). At 2:00 a.m., 10:00 a.m. and at 6:00 p.m.
.5 ) Regeneration frequency every 12 hours (2 times per day). At 2:00 a.m. and at 2:00 p.m.
1-30 ) With the value set at 1, you will have a daily frequency, with 2 the regeneration will start every 2 days and so on until
the value of 30, with a regeneration every 30 days. The regeneration will always start at 02:00 a.m.
Push the icon button until the display shows the value derived from the table attached.
MANUAL REGENERATION
DELAYED REGENERATION
For a delayed regeneration, push the con button and release it immediately.
In this way, a delayed regeneration will be set, at 2:00 a.m. of the following day, independently from the regenerations already
set. A flashing dot will be displayed next to the time to confirm the correct set up.
To cancel this set up, push the button again.
IMMEDIATE REGENERATION
For an immediate regeneration keep the icon button pushed for 3 seconds.
The display will show ( - - ) in vertical cascade, indicating the counter washing stage processing.
For each stage C2 - C3 etc. will be displayed until the regeneration is complete has been completed.
To scroll the regeneration cycle after having launched manual regeneration, push and release the and buttons at the
same time until the display shows the following cycle.
To reset the regeneration programme and go back to the operating stage push the and icon buttons at the same time
for 3 seconds.

GENERAL WARNINGS
This chapter contains the complete list of requirements and of procedures referring to maintenance.
A good maintenance requires ordinary checks and inspections, performed directly by the operator and/or by skilled sta,
and periodic checks, including cleaning operations and replacement, performed by skilled sta.
During cleaning, maintenance or repair operations, be careful not to disperse the products used in the environment.
After all maintenance operations restore and correctly fasten all protection removed or opened.
MAINTENANCE
IMPORTANT
Do not perform any operation, change or repair except those indicated by this manual.
Only skilled technical sta or sta authorized by the manufacturer have the necessary know-how of the system and the experience
to correctly perform any operation.
All maintenance sta must comply with safety regulations and must wear protection gloves and shoes to move or remove objects
that could be harmful.

WARNING
All maintenance operations must be performed with the system in the” safety stop” condition and disconnected from all power and
supply sources.

MAINTENANCE
Immediately repair possible failures or damages to covers and electric appliances.
OPERATIONS BEFORE COMMISSIONING:
• General visual inspection (evident warps or damages of structure, protections, etc.);
• Check of the conditions of the power supply cable.
The softener does not require any kind of ordinary maintenance but the check and refill of salt.
The hour set must correspond to current time. It is important to check the softener periodically to safeguard the eciency
of connected devices.
These operations include checking water hardness and input and output capacity, the right execution of the dierent stages
and the conditions of resins to replace them if necessary.
DANGER
Never perform the operations above with wet or damp hands.

PERIODIC CHECKS
AFTER THE FIRST 6-12 MONTHS, AND THEN EVERY 6-12 MONTHS:
Clean the salt container following the procedure hereunder:
• Remove the remaining salt from the bottom;
• Clean all the walls of the container from muddy, oozy or dry salt deposits;
• Rinse several times with running water using a water disinfectant such as Amuchina and a sponge;
• Rinse again, add the same quantity of water and then add the salt.
