2 - VALVE INSTALLATION
37700 VALVE
Water pressure
A minimum of 1,4 bar of water pressure is required for the regeneration valve to operate effectively.
Do not exceed 8,5 bar ; if you face this case, you should install a pressure regulator upstream the system.
Electrical connection
An uninterrupted current supply is required. Please make sure that your voltage supply is compatible with your
unitbeforeinstallation.Iftheelectricalcableisdamaged,itmustimperativelybereplacedbyaqualifiedpersonal.
Existing plumbing
Existing plumbing should be in a good shape and free from limescale.
The installation of a pre filter is always advised.
By-pass
Always provide a by pass valve for the installation, if the unit is not equipped with one.
Water temperature
Water temperature is not to exceed 43°C, and the unit cannot be subjected to freezing conditions.

Install the unit in a chosen place on a flat firm surface.
During cold weather, it is recommended to bring the valve back to room temperature before operating.
All plumbing for water inlet, distribution and drain lines should be done correctly in accordance with legislation in
force at the time of installation.
The distribution tube should be cut flush with the top of the tank. Slightly bevel the ridge in order to avoid
deterioration of the seal whilst fitting the valve (View sketch below).
Lubricate the distribution tube joint and the joint with a 100% Silicon lubricant. Never use other types of greases
that may damage the valve.
All soldering on main plumbing and to the drain line should be done before fitting the valve. Failing to do so can
generate irreversible damages.
Use Teflon® tape if necessary in order to seal between the drain fitting and the outlet flow control.
On units with by-pass, place in by-pass position. Turn on the main water supply. Open a cold soft water tap nearby
and let run a few minutes or until the system is free from foreign material (usually solder) that may have resulted
from the installation. Once clean, close the water tap.
Place the by-pass in service position and let water flow into the mineral tank. When water flow stops, slowly open
a cold water tap nearby and let run until the air is purged from the unit.
Plug the valve to a power source. Once plugged the valve may do a cycle on its own in order to go to service
position.

Timeclock regeneration
The number of days between each regeneration cycle is preset. Once reached, regeneration is triggered at the
programmed time.
Metered regeneration
The valve calculates the amount of water it can soften between 2 regenerations based on the exchange capacity
(m3°tH) and inlet water hardness that are preset.
Immediate or meter delayed regeneration valves
As softened water is used, the remaining volume display will decrease until reaching its reserve capacity (meter
delayed regeneration) or until zero (immediate metered regeneration). When this happens, regeneration is
automatically triggered either straight away or at a preset time.
Service
Service display
Inoperation,thetimeofthedayandthevolumeremainingwill alternatively be displayed (except for the time clock

If the remaining volume is higher than 9999 litres, the letter « t » will appear
to indicate that the indicated number must be multiplied by 1000.
I.E. t 15 = 15 *1000 = 15 000 litres capacity.
In delayed metered regeneration, this display indicates that the remaining
capacity is exhausted. The service position L.E.D will flash and a
regeneration cycle will start at the programmed time.
Time of day setting
Set the time of day minute by minute by pressing the or button. Press and hold the button to set quickly
the time of day.
Regeneration
Regeneration displays
During the regeneration cycle, the valve will show the current cycle number the valve is advancing to (flashing
display) or has reached as well as the time remaining in that cycle (fixed display). Once all the regeneration cycle
steps have been completed the valve will return to the service position.
For example:
The valve is advancing to its 2nd cycle.
The number 2 and the L.E.D. are flashing. The valve is in its 2nd cycle; there are 65 minutes left.
8P Vanne 7700 ANG 8/03/05 19:21 Page 5

Start a manual regeneration
There are 2 options to initiate regeneration.
A) Press and release the button.
If an immediate regeneration is programmed, the valve will immediately start regeneration.
With a delayed regeneration, the service L.E.D. will begin to flash immediately and the regeneration will occur at
the preset regeneration time.
B) Press and hold for 5 seconds the button.
In any case the valve will go into regeneration immediately.
Advance to the next regeneration cycle
To advance to the next regeneration cycle, press the button.
This will have no effect if the valve is already advancing to the next cycle.
PROGRAMMING
CAUTION: The programming has to be done only by the installer for the setting of the valve parameters. The
modification of one of these parameters could prevent the good functioning of the device.
To enter the program mode, the valve has to be in service. While in program mode, the valve will continue to
operate normally monitoring all information. The programming is stored in permanent memory with or without line
or battery backup power.
To enter programming mode, press simultaneously the and for 5 seconds.
Press on the button in order to jump to the next stage.
Use the and buttons in order to modify the displayed values.
Note: You must pass through all the programming steps and come back in service position to save the
modifications that have been done during the programming mode.

- Press the button to advance to the next programmation stage.
Display unit
Notice: if this setting has just been changed, the valve will go around fully and come back to service mode.
Default setting: [U--1]
This setting is identified by the letter U. There are two types:
- [U - - 1] US type: the measure unit is in gallons, time display is 2x12 hours, hardness in grain.
- [U - - 2] metric type: the measure unit is litre, time display is 24 hours, hardness in m3x°Th.
Regenerating way
Notice: if this setting has just been changed, the valve will go around fully and come back to service mode.
Default setting : [dF]
This display is used in order to tell the card the piston type used on the valve.
- dF : down flow
- dFFF : down flow with brine fill first
- Fltr : Filter
Regeneration type
Default setting : [7--3]
This setting is identified by the number 7. This function allows the setting of the valve regeneration type. There are 3 possibilities:
- Time clock: The electronics establish that a regeneration is requested when the number of days between two regenerations
has been reached; the new cycle beginning at the preset time. The setting of the day override establishes the number of days
between two regenerations. [7--1]
- Metered immediate regeneration: The electronics establish that a regeneration is required when the softened water volume
has reached zero. The regeneration starts immediately. [7--2]
- Meter delayed regeneration: The electronics establish that a regeneration is requested when the volume of softened water
used has reached the reserve capacity of the unit. Regeneration will begin at a preset time; the system will automatically
establish a reserve capacity. [7--3]
System capacity
Not visualized in time clock mode: [7--1]
This setting is identified by the letter C. It contains an extended mode Ct, the letter t meaning a multiplication by 1000.
It enables the regulation of the system capacity in m3x tH°.
The system calculates the water volume that needs to be treated before a regeneration request.
In meter delayed mode, the system will establish a reserve capacity.
I.e. : 35 m3°tH [C-35]
Feed water hardness (H)
Not visualized in time clock mode: [7--1).
Default setting: [H-15]
This setting is identified by the letter H. It enables the regulation of the feed water hardness.
The system uses this setting and the previous one to establish softened water capacity.
I.e. : 25 °tH [H-25]
Regeneration time
Not visualized in immediate metered mode: [7--2]
It allows setting of the regeneration time. The two dots between hour and minute display do not flash in order to differentiate
with the current time display.
I.e. : regeneration at 2 :00 A.M. [2:00]
Day override
This setting is identified by the letter A. It allows to set the maximum amount of days that the system can stay in service mode
without a regeneration. This stage is compulsory for a valve in time clock mode and optional for a valve in metered mode.
I.e. regeneration every 7 days [A--7]
