Introduction
The 2400VS is an electronic 4-cycle regeneration control valve for softening of drinking and feed water supplies.
The unique motor driven rotor assembly has a minimum of moving parts; together with the 1-piece Noryl® body,
this guarantees extremely high flow rates and exceptional reliability. The microprocessor controlled programmer
with NOVRAM®, offers unrivalled programming simplicity for use in demand with days override systems. The
control valve is designed for hard water bypass during regeneration. A built in adjustable blending device for
mixing hard and soft water to suit the particular needs of each installation, is a standard feature. The control valve
requires only an aircheck; a conventional float-controlled brine valve system can be used as a double security. The
following sequence is followed:
1. SERVICE:
Untreated water flows down through the resin bed and up through the riser tube; the water is conditioned when
passing through the resin. The throughput is dependent on the maximum permissible pressure drop for the
complete water softener and the maximum permissible specific load of the resin (generally taken as 40 litres
soft water per hour per litre resin).
2. BACKWASH:
Water flows down through the riser tube and up through the resin bed to drain; the resin bed is fully expanded
and all foreign materials are thoroughly washed from the resin, allowing a good brine cycle to occur.
3. BRINE:
Salt brine, drawn from the brine tank by the injector, slowly flows down through the resin bed and up through
the riser tube to drain; the resin is being regenerated when the salt brine passes through. The brine cycle is
terminated when the air check is shut.
4. SLOW RINSE:
Slow rinse continues for the remainder of the brine cycle; the injectors motive water slowly flows down through
the resin bed and up through the riser tube to drain, slowly washing the brine from the resin tank.
5. FAST RINSE/BRINE REFILL:
Water flows to the brine tank and at the same time down through the resin bed and up through the riser tube to
drain, ensuring that all traces of brine are washed out and that the resin bed is compacted. The resin bed is now
ready for the next service cycle.

Installation
Assembly
For proper assembly of control valve and resin tank, proceed as follows:
1. Rinse the resin tank well before use.
2. Attach the lower distributor to the riser tube using PVC-glue or a stainless steel pin.
3. Lower the riser tube into the resin tank so that it touches the bottom.
4. Cut the riser tube 13 mm (= 1/2”) below the top of the tank threads and chamfer the tube to prepare for
insertion into the control valve.
5. Temporary plug the top of the riser tube to prevent resin from entering the tube and fill the tank with resin for
max. 3/4 full.
6. Make sure the O-ring in the riser insert of the control valve is in the correct position; screw the upper
distributor onto the control valve.
7. Lubricate the threads, the top of the riser tube and the tank O-ring of the control valve.
8. Lower the control valve straight down onto the riser tube and screw it onto the tank.
Installation
!!! ATTENTION
For proper functioning of the unit, incoming water pressure should be between a minimum of 1,4 bar during
regeneration and a maximum of 8,3 bar in service; if necessary, a pressure reducer must be installed ahead of
the system.
Installation must only be undertaken by a person competent in plumbing.
All plumbing and electrical connections must be done in accordance with local codes.
Do not install the unit too close to a water heater (min. 3 m of piping between outlet of unit and inlet of heater);
water heaters can sometimes transmit heat back down the cold pipe into the control valve; always install a
check valve at the outlet of the system.
If the control valve is not equipped with a bypass, a three valve bypass system must be installed to enable
bypassing during servicing.
For proper installation of the unit, proceed as follows:
1. Inlet/outlet: connect the inlet and outlet to the control valve; when facing the front of the control valve, the
inlet is at the left and the outlet at the right side.
2. Drain line: connect a hose to the drain line fitting on the control valve and secure it; insert the drain hose into
a standpipe, with siphon if required; make sure the drain hose is:
as short as possible,
not elevated too much,
free of kinks,
as this will all create undesired counter-pressure.
3. Brine line: an aircheck is required for proper brining during regeneration, but a float-controlled brine valve
system can be used as a double security; 3/8” polytube must be used to connect the brine system to the control
valve; do not overtighten the nut.
4. Transformer: make sure the power source carries the same rating as the transformer; plug transformers output
lead (with plug ø 2,5 mm x 5,5 mm) into socket at the timers power lead and plug transformer into socket; the
connection can be secured by means of the wire clip.

Installation check-out
When installation has been completed, the unit is ready to be placed into service. Proceed as follows, while
checking the unit for any leakages:
1. Place unit in bypass and turn on main water supply; open a cold water tap nearby and allow water to run for a
few minutes until all foreign material that may have resulted from the installation is washed out; close the tap.
2. Slowly shift the bypass valve to the service position and secure it; allow water to completely fill the resin tank.
3. Carefully open a cold water tap and allow water to run for at least 2 minutes to set the resin bed and purge air
from the unit; close the tap.
4. Program the control valve according to the specific installation (refer to “Programming” on pg. 11).
5. Press the scroll button repeatedly until the display shows:
6. Leave the control valve in this position; the countdown timer will countdown to 0 sec and start a regeneration.
7. The motor will start and the display will show:
8. You can press the scroll button again to switch the motor to full speed, which will shorten the transfer time
needed by the control valve to reach the next position.
9. The motor will move the control valve into backwash position; allow water to run to drain until all of the air is
purged from the system.
10.Fill the brine tank with water, higher then the air-check level.
11.Press the scroll button; the motor will start and the display will show:
12.The motor will move the control valve into brine/slow rinse position; allow it to draw water from the brine tank
until the aircheck closes.
13.Press the scroll button; the motor will start and the display will show:
14.The motor will move the control valve into fast rinse/brine refill position; allow water to run to drain and brine
tank for the entire cycle time, to fill the brine tank to the programmed level.
15.Add salt to the brine tank.
Mixing valve
To adjust the residual hardness, the incorporated mixing valve must be regulated in function of the hardness of the
incoming water and the desired residual hardness
To increase the residual hardness: turn screw counter clockwise.
To decrease the residual hardness: turn screw clockwise.

After power-up, the display will show the installed software version for 5 seconds, f.e.:
Afterwards it will automatically revert back to the service display.
The POWER led will light up.
Power failure
In the event of a power failure, the program will remain stored in the NOVRAM® during an undefined period,
while an incorporated SuperCap (capacitor) will maintain the correct time of day during a period of several hours;
consequently, in case of prolonged power failure, the time of day might not be maintained; if this happens, the time
of day indication will flash when the power supply is re-established, indicating that the time of day needs to be set.
When the power failure occurs during the execution of an automatic regeneration, the control valve will remain in
it’s last position; when the power supply is re-established, the control valve will return to the service position, stay
there for 60 sec. and restart a complete regeneration from the beginning.
Timer failure
In the event of a timer failure, the display will show the message:
In such case, entering one of the programming levels can possibly solve the problem. However if the problem
persists, professional service is required.

Service mode
In service mode the display shows the time of day, the remaining capacity and the water usage indicator:
Every day the control valve automatically recalculates the reserve capacity, as a progressing average. Permanently
it compares the remaining capacity with the calculated reserve capacity; as soon as the remaining capacity equals
the calculated reserve capacity, the display will show the time of day and the indication “REGEN”, indicating that
a delayed regeneration will be started at the pre-programmed time of regeneration:
In case the resin bed is fully exhausted (remaining capacity equals zero) before a delayed regeneration can take
place, the unit will regenerate immediately.
Regeneration mode
In regeneration mode the display shows the total remaining regeneration time, the actual regeneration cycle and
the remaining cycle time:

Rotor assembly
1. Remove the drain hose from the drain elbow.
2. Remove the 6 bolts holding the valve body and cover together.
3. Lift the valve cover away from the valve body.
4. Remove the rotor assembly from the valve cover; the white Teflon O-ring will remain in the valve cover.
5. Inspect the rotor plate’s surface; it should be smooth and free of any circular grooves or scratches; replace if
necessary.
6. Install the rotor assembly into the valve body ensuring that the
arrow on the worm gear is pointing directly towards the second
tooth on the worm drive shaft (facing the front of the control valve);
the 2 holes in the rotor assembly should now be exactly aligned with
the corresponding holes in the seal disk.
7. Centre the PVC sleeve on the worm gear.
8. Make sure the valve cover O-ring is clean and securely installed
around the raised rib on the valve cover.
9. Lower the valve cover straight down onto the valve body and press it
down firmly and evenly to seat the valve cover.

11.Install the drain hose to the drain line fitting.
Seal disk
1. Remove the rotor assembly; refer to Parts Replacement “Rotor assembly”.
2. Remove the seal disk from the valve body.
3. Inspect the seal disk; make sure the raised ribs are intact; the green Teflon coating may be worn off of the ribs,
but this won’t affect the sealing performance of the seal disk; replace if necessary.
4. Use silicone base lubricant to lubricate the green side of the seal disk.
5. Install the seal disk in the valve body, with the green side facing up.
6. Reverse the procedure for reassembly; refer to Parts Replacement “Rotor Assembly”.
