Before every cleaning and maintenance intervention, disconnect the
appliance from the mains by switching off the master switch.
Wait until the parts have cooled down to avoid the risk of burns.
Do not use abrasive sponges or abrasive or corrosive detergents to
avoid damaging the painted surfaces.
When necessary, clean the outer surfaces of the FCU with a soft and damp cloth.
The lockshield provide an adjustment that balances the system load
losses. To ensure a correct adjustment and balancing of the circuit, follow
the procedure indicated below:
• With a screwdriver, loosen and remove the slotted grub screw
inside the hexagonal screw.
• Close the hexagonal screw using a 5 mm Allen key (A)
• Re-tighten the slotted grub screw, then mark the reference point for the
adjustment with an “x” (B).
• Align the screwdriver with the “x”, then open with a number of turns (C)
according to diagram shown on page 09.
The number of turns refers to the slotted grub screw.
Then fully open the hexagonal screw (D). Now the pre-adjustment has been
set and will not change if there are repeated openings or closings of the
hexagonal screw.
