Frequently Asked Questions - 5600 FLECK

Why is the softener not regenerating?

Check the power supply, meter cable, motor and programming. If the motor is defective, replace it. Refer to the troubleshooting table in the manual.

Why is the output water hard?

The bypass may be in 'bypass' position, the brine tank empty, the injector or filter clogged, or the meter blocked. Also check the hot water hardness.

What if salt consumption is excessive?

Check the refill setting and the water level in the brine tank. Incorrect programming can also be the cause.

How to solve a drop in water pressure?

Clean the inlet line, valve and resin if iron deposits are present. Check that the valve inlet is not obstructed.

Why is there resin lost in the drain?

Check the top strainer (missing or broken), air in the softener and the drain flow control size.

How to remove iron in the softener?

Clean the resin bed, increase regeneration frequency and backwash duration. If iron content exceeds recommendations, contact your dealer.

Why is there too much water in the brine tank?

The drain flow control (DLFC) may be clogged, the brine valve defective or programming incorrect. Clean or replace the affected parts.

Why is the output water salty?

The injector or filter is clogged, the control head is not working correctly, or water pressure is insufficient (must be at least 1.8 bar). Clean or replace components.

Why is there no brine suction?

Check the drain flow control, injector and filter. If pressure is below 1.8 bar, increase it. An internal leak or incorrect programming can also be the cause.

What if the valve regenerates continuously?

The control head may be defective, the microswitch or wiring harness damaged, or the cycle cam misadjusted. Replace defective parts.

Valves complying European regulations:

• Nr. 89/336/EEC, "Electromagnetic compatibility",
• Nr. 73/23/EEC, "Low voltage"

2.1 WATER PRESSION

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.

2.2 ELECTRICAL CONNECTION

An uninterrupted current supply is required. Please make sure that your voltage supply is compatible with your unit before installation. If the electrical cable is damaged, it must imperatively be replaced by a qualified personal.

2.3 EXISTING PLUMBING

Existing plumbing should be in a good shape and free from limescale. In doubt, it is preferable to replace it. The installation of a pre filter is always advised.

2.4 BY-PASS

Always provide a by pass valve for the installation, if the unit is not equipped with one.

2.5 WATER TEMPERATURES

Water temperature is not to exceed 43^ , and the unit cannot be subjected to freezing conditions.

3.1

Install the softener pressure vessel(s) in a chosen place on a flat firm surface.

3.2

During cold weather, it is recommended to bring the valve back to room temperature before operating.

3.3

All plumbing for water inlet, distribution and drain lines should be done correctly in accordance with legislation in force at the time of installation. Install without tension or bending stresses.

3.4

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.

3.5

Lubricate the distribution tube joint and the joint with a 100% Silicon lubricant. Never use other types of greases that may damage the valve.

3.6

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.

3.7

Use Teflon® tape if necessary in order to seal between the drain fitting and the outlet flow control.

3.8

On units with by-pass, place in by-pass position. Turn on the main water supply. Open a cold 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.

3.9

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.

3.10

Plug the valve to a power source. Check that the valve is in service position

3.11

Fill approximately 25mm of water above the grid plate, (if used). Otherwise, fill to the top of the air check in the brine tank. Do not add salt to the brine tank at this time.

3.12

Initiate a manual regeneration, bring the valve into « brine draw and slow rinse position » in order to draw water from the brine tank until the blockage of the air check; the water level will be approximatively in the middle of the air check.

3.13

Open a cold water tap and let the water run in order to drain the air out of the circuit.

3.14

Bring the valve in brine refill position and let it get back to service position automatically.

3.15

Now you can add salt to the brine tank, the valve will operate automatically.

METERED

White dot

Set the capacity of soft water between 2 regenerations using the following formula:

Water capacity in ^3 = exchange capacity in m^30tH - reserve capacity in ^3

Water hardness tH

To do so, lift the transparent disc with the label and display the capacity facing the white dot.

Example for the following drawing, the capacity set is 6.6 cubic meters between two regenerations.

TIME CLOCK

Pin pushed outside

Use the same formula as for metered version and divide by daily water consumption to obtain the number of days between 2 regenerations.

There are two time clock wheels:

• 7 days: based on the week, number 1 will refer to Monday, number 7 to Sunday.
• 12 days: allows to set a regular interval every 2, 3, 4, or 6 days.

To set up, push the pins out.

Example: on the drawing one regeneration every 2 days.

COMMON SETTINGS

Time of day

Press the clutch on the 24 hour wheel, red gear, then turn the hour wheel to display the correct hour in the window.

Salt volume per regeneration

Here is a table, usually used in water treatment.

SALT WEIGHT N G / LITRE OF RESIN	EXCHANGE CAPACITY IN °TH / M2/ LITRE OF RESIN	SALT WEIGHT IN G / °TH / M2
80	4	20
125	5	25
180	6	30

On the brine cam, there is a segment and a indication Label in Kilogram. This segment with an indicator ensures the function of brine refill. Based on the table, set the amount of salt in Kg necessary for the resin regeneration. This way, the valve will send the correct volume of water in the brine tank in order to dissolve the necessary volume of salt for regeneration.

Example: 15 litres of resin x 125g = 1875g (1.9 kg of salt)

Place the indicator slightly under 2kg

OPTIONS

Hot water available only on the 4600 valve:

The use of specific materials allows the valve to work at temperatures higher than 43^ : Up to 82^ for a timeclock version or 65^ for a metered version.

Immediate Regeneration:

As opposed to time clock or metered valves that regenerate at 2 A.M. this option allows the valve to regenerate immediately after the set capacity is consumed

Fast Regeneration (FR):

This option allows the valve to regenerate in 90 minutes instead of 180 minutes. This valve can only be fitted with vessels up to 10^ .

Low water usage piston (L.W.U.):

With this piston, water consumption during regeneration can be reduced.
