Q: How to set the capacity in cubic meters on the FLECK 5600?

The FLECK 5600 uses a volumetric system in cubic meters (m³) , not in gallons. Here’s how to set the softening capacity: Configuration Steps Locate the transparent disk on the control panel, with a white reference dot indicator Lift the transparent disk to access the capacity graduations Calculate your usable capacity using the formula: Capacity (m³) = exchange capacity (m³) - reserve capacity (m³) Align the white reference dot with the calculated capacity value Close the disk and read the displayed capacity (e.g.: 6.6 m³ between two regenerations) The capacity depends on the specifics of your installation and the volume of resin available. The volumetric system in m³ offers more precision than a gallon assessment for this type of softener.

Question 1

How to set the capacity in cubic meters on the FLECK 5600?

Accepted Answer

The FLECK 5600 uses a volumetric system in cubic meters (m³), not in gallons. Here’s how to set the softening capacity:

Configuration Steps

Locate the transparent disk on the control panel, with a white reference dot indicator
Lift the transparent disk to access the capacity graduations
Calculate your usable capacity using the formula: Capacity (m³) = exchange capacity (m³) - reserve capacity (m³)
Align the white reference dot with the calculated capacity value
Close the disk and read the displayed capacity (e.g.: 6.6 m³ between two regenerations)

The capacity depends on the specifics of your installation and the volume of resin available. The volumetric system in m³ offers more precision than a gallon assessment for this type of softener.

Question 2

How to operate and install the FLECK 5600?

Accepted Answer

The operation of the FLECK 5600 involves several essential steps that must be followed meticulously to ensure optimal functioning of your water softener.

Initial preparation and installation
First, install the FLECK 5600 on a flat and stable surface. In cold weather, it is recommended to bring the valve to room temperature before any installation. Cut the distributor tube flush with the neck of the bottle and slightly bevel the edge to avoid damaging the sealing gasket. Before connecting the valve, perform the soldering on the main plumbing and the sewer connection, to avoid irreversible damage. Then lubricate the joints of the distributor tube and the base with a 100% silicone lubricant only.

Hydraulic connections and pressure conditions
Use Teflon® tape to ensure a seal between the sewer connection and the flow regulator. Water pressure is critical: it must be between 1.4 bar (minimum) and 8.5 bar (maximum). If you exceed 8.5 bar, install a pressure limiter upstream. Also, check that the water temperature does not exceed 43°C and that the installation is not subject to freezing.

Starting up and filling the bottle
Set the bypass to the “bypass” position and open the main water supply. Let a cold water tap run for a few minutes to flush the lines of foreign bodies (welding residues). Then set the bypass to “service” position and let the water fill the bottle gradually. Once the flow stops, open a cold water tap to purge the residual air. Fill the salt tank with water about 25 mm above the floor (or until the brine diffuser is covered), without adding salt for now.

Starting regeneration cycles
Plug in the device (230 V/50 Hz or 24 V/50-60 Hz with transformer) and check that the valve is in service position. Trigger a manual regeneration by positioning the valve on “suction and slow rinse” to draw water from the tank until the anti-air valve is blocked. Once this phase starts, open a cold water tap to purge the air from the distribution network. Then bring the valve to the “return water to the salt tank” position and let it automatically return to service position.

Salt settings and finalization
Completely fill the salt tank now that the valve has emptied of water. The salt dosage follows the formula: 80 to 180 grams per liter of resin depending on the hardness of the water (80 g for 4°tH/m³/liter, 125 g for 5°tH/m³/liter, 180 g for 6°tH/m³/liter). Set the corresponding amount on the brine cam in kilograms. Once all settings are completed, the FLECK 5600 can operate fully in automatic mode. The green light on the control panel indicates normal service mode, while the red light signals that regeneration is in progress. You can now program the regeneration parameters (volumetric or timed) according to your water consumption needs and the initial hardness of your water.

Question 3

How to use the FLECK 5600 water softener?

Accepted Answer

The FLECK 5600 water softener is designed to reduce water hardness in your home installation. Here’s how to use it effectively:

1. Installation

Ensure that the softener is correctly installed on the main water supply line. Professional installation is recommended to ensure optimal operation.

2. Start-up and initial settings

Turn on the device.
Set the local water hardness on the control panel, according to the results of a water hardness test.
Adjust the time and frequency of automatic regeneration if necessary.

3. Regeneration

The softener automatically performs a regeneration cycle to recharge the resin with sodium ions. Check that the salt tank is always filled to ensure this process.

4. Maintenance and monitoring

Regularly check the salt level and add more if needed.
Monitor the proper functioning of the cycles and the quality of the softened water.
Perform periodic maintenance, including cleaning the filters if your model is equipped with them.

By following these steps, your FLECK 5600 softener will operate efficiently to protect your installations and improve the quality of your water.
