8.3 Continuation of initial start-up after successful adjustment
of the recovery rate
» Connect the permeate pipe to the following consumer.
» Open the shut-off cocks of the expansion vessel
» Check whether the system switches off after reaching the operating pressure (approx. 4 bar).
When the pres- sure expansion vessel is completely filled, the pressure rises automatically (read the value on
the pressure gauge of the expansion vessel).
If the system does not switch off when the operating pressure exceeds approx 4 bar, consult HygroMatik.
» Check the system for leaks.
» If leaks appear, switch off the unit immediately. Locate and eliminate leaks
» Repeat the tightness test
8.4 Filling the antiscalant tank
The antiscalant liquid is used to prevent cal- cium and magnesium residues present in the feed water from depositing
on the membrane, causing a decline in performance and reducing operating life. The dosing pump feeds the desired
antiscalant dose into the feed water circuit.
Filling the canister
Before filling the antiscalant canister, take the required amount of antiscalant (depending on the water hardness) from
the table in the chapter Technical Data.
» Using a measuring cup, thin the anti- scale in the canister with permeate (use the permeate produced during
the commissioning phase for this step).
» Make sure not to damage the float when closing the cap on the tank.
8.5 Adjusting the metering pump

When the activity LED is green, the metering pump supplies an amount 10 times higher than the nominal value. Only
use this setting after consultation with the specialist dealer or HygroMatik.
In standard operation, you use the dosing pump with the divider switched on (orange LED lights up constantly).
To supply the dosing pump with the antiscalant mixture from the canister, pro- ceed as follows:
» Switch off the divider, the colour of the LED changes to green.
The DIVIDER is switched on and off as fol- lows:
» Short press on the ON/OFF button (pump goes into standby mode).
» Long press on the ON/OFF button, after 4 short flashes the LED chan- ges colour.
Only then release the pressure on the button
» Set the rotary knob to 100% (fast pulse frequency).
» Open the vent screw (A)
Fig. 8.d
» Close the vent screw (A) when the transparent tube is completely filled with the antiscalant mixture.
