HELP WITH CLACK WS1TT INSTALATION

[Madvic]

hi;
I recently install a WS1TT in softener mode,
I used a 1465 tank with 75L resin and gravel at the bottom. And fails to regenerate. More on the issue later, first I will copy the settings:

I installed the plugs for the second tank, So no twin tank.
The service menus are:
Next+Down

1-Backwash 8min
2-Brone Dn 60 min
3-Backwash 8min
4-Rinse 4min
5-Fill (4.25kg)
capacity 3.30
regen aut0
Regen ON
Rly1

the second service menu Next+Down:

1-1.0T
2-Pre 20 min rinse
3-Dp OFF
4-Hardness PPM
5-Backwash
6-Dn Brine
7-Back Wash
8-Rinse
9-Fill
10-End
11-loDc.

So the problem is that the unit fails in:
the backwash (no drain water detected)
Brine dn (the unit injects water in brine tank and doesnt suck it)
rinse: nothing happens

I opened the injector port, and I see that the unit have a plug in DN and a violet injector in UP.

I swapped it (violet injector in DN and plug in UP). And hit the regen once again.
Now the unit does this:

rinse: nothing happens
backwash: (seems ok) water in the drain
brine dn: sucks water from brine tank
fill: nothing happens.

Also the unit has a clack bypass valve, in regen the bypass is not "bypassed" so the unit can take water form the pressure pump (6bar).

I'm no expert and I need technical support help from you!!! , I purchased the valve long time ago from a person that purchased it and never installed. And the bypass valve recently in a UK store.

Many thanks for your support and sorry for the long text but im a Little (quite) desperate, and frankly im stuck.
Maybe the valve is set to have the injectors reversed ( upflow instear of downflow operation9 and something inside need to be changes also.
please I need help, I cant move to my new home until I fix this and Im paying a loan and also a rental flat..! So every bit of help would be more than appreciated.

many thanks again.

Verify that the unit is plumbed correctly. Page 2 of the WS1TT manual states the following:

Twin Valve Installation Tips:​

We have had a number of instances where customers have incorrectly installed the in/out head to the untreated
water inlet/treated water outlet of the control valve, rather than to the 2nd tank connection ports.
Below are a number of situations that will occur when the in/out head is incorrectly installed to the untreated
water inlet/treated water outlet of the control valve.
1) When “A” is in the draw cycle it will not draw brine and will put water into the salt tank. The “B” tank will
draw properly.
2) When “B” is in the backwash cycle, “A” will have no flow to service.
3) The transfer disc seals may be forced out of their cavities on the back/motor side of the transfer discs, and
it is possible that one of the seals could get pushed up into the valve and get stuck in the top of tank port of
the spacer stack assembly.

In addition, Upflow Brining and Downflow Brining each utilize a different piston in addition to different Injector/Plug port placement and program settings. Page 4 of the WS1TTManual states:

Note: The downflow piston is a solid amber color. The upflow piston is black and amber.

I have not yet located any mention of correctly configuring the WS1TT for use with 1 media tank.

Edit to add: Although Downflow Brining is usually recommended for residential applications, Up-flow Brining seems to be how your control valve was initially configured.

According to the chart on page 9 of the manual, a VIOLET Injector is appropriate for an 8" diameter Downflow tank, or a 10" diameter Up-flow tank. For your 14" diameter tank, a Green Injector is specified for Downflow Brining whereas for Up-flow Brining, a Blue injector is indicated. These injector sizes are based on minimum 15.6C incoming water temperature within a pressure range of 2.1 to 3.4 bar.


Page 9 of the manual also specifies:

2. upflow softener using standard mesh synthetic cation exchange media regenerating
with sodium chloride, an inlet water pressure of 30 to 50 psi (2.1 to 3.4 bar) and water
temperature of 60°F (15.6°C) water or warmer. Higher pressures or lower temperatures
would need smaller injectors to avoid lifting the bed.

In addition to the above, since it seems your unit was initially configured for a 10" up-flow tank, the DLFC (drain line flow control restrictor) will be also likely inappropriate.

For a 14" diameter tank, depending on your water temperature, the drain flow rate should be increased to approx. 4.75 gpm (17.995 L/minute), assuming 15.6 C water temperature.

I have searched for the words 'single', 'single tank', 'one', 'one tank', '1', '1 tank', and found nothing related to instructions on how to configure a WS1TT for use with only one tank. Perhaps you may need to add a 2nd tank for that valve to function properly.
