8.3 Continuation of initial start-
up after successful adjust-
ment 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 pres-
sure (approx. 4 bar). When the pres-
sure expansion vessel is completely
filled, the pressure rises automati-
cally (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 mem-
brane, 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 using the recommended antiscalant
Permaclean 309
» Position the fl ow control knob at
30%
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)
