PRELIMINARY INFORMATION

Mixers of the LESS series are fit for operating with hot water
collectors under pressure, instantaneous and gas water-
heaters.
ATTENTION: the connection with hot water collectors
without pressure (with open circuit) is not possible.

TECHNICAL DATA

- Minimum dynamic pressure . . . . . . . . . . . . . . . . 0,5 bar
- Maximum operational pressure (static) . . . . . . . . 10 bar
- Recommended operational pressure (static) . . . . 1-5 bar
(N.B.: for pressures higher than 5 bar we suggest the
installation of a pressure reducer)
- Maximum test pressure (static) . . . . . . . . . . . . . . 16 bar
- Maximum hot water temperature . . . . . . . . . . . . 80°C
- Suggested hot water temperature . . . . . . . . . . . 60°C
(for energy saving)
INSTALLATION (ref. Fig. 1 - Fig. 2 )
- Screw the flexible hoses (1) to the mixer using a 11 mm
wrench positioning it in the special millings.
- IMPORTANT: during the flexible hoses' assembly
operations, DO NOT HOLD the sleeves of the flexible hoses
with hexagonal wrenches or adjustable pincers that,
damaging them, would compromise the safety of the
installation (see Fig. 1).
- Screw the fixing shaft (2) to the mixer and insert the rod (3)
of the pop-up.
- Clamp the mixer to the ceramics by clamping vice (4) and
12 mm. hexagonal lock-nut (5) (see Fig. 2).
In case of washbasin tops' thickness inferior to 6 mm, insert
the special distance piece (6) between the clamping vice
and the ceramics' protecting gasket.
- Assemble the tail-pieces (7) taking care that the one with the
RED little stamp is positioned on the warm water-side and
that the protrusion from the washbasin top is included
between 38 and 42 mm. (38 mm is suggested). (see Fig. 3).
- Fix the tail-pieces (7) to the ceramics; tightening the upper
nut by a 38 mm. wrench.
- Screw the 90° connections (8); tightening the nuts by a 17
mm. wrench.
- Connect the mixer to the tail-pieces (7) screwing the G3/8''
nuts of the flexible hoses by a 19 mm wrench.
- Screw by hand the headvalve escutcheons (9).
- Assemble the handles (10) so that – by TURNED OFF faucet
– the levers are turned to the user and fix them to the tail-
pieces (7) tightening the screw (11) by a 2 mm Allen
wrench (supplied).
- Insert the hole covering cap (12).
- Assemble the automatic pop-up and connect it to the rod
with the (supplied) connection.
- Connect the tail-pieces (7) to the installation, open the
water pipes and check the tightness of the connections and
the good operation of the mixer (maximum test pressure 16
bar static).
REPLACEMENT OF THE HEADVALVE
WITH CERAMIC DISCS (ref. Fig. 4)
- Close the hot water and cold water inlets.
- Remove the hole covering plate (1) and unscrew the locking
pin (2) by a 2m ALLEN wrench.
- Remove the lever and unscrew the headvalve escutcheon (3).
- Unscrew the headvalve by a 17 mm wrench and replace it
with a new one, paying attention to the gasket's (A) colour
(RED for WARM water and BLUE for COLD water).
- Screw the headvalve escutcheon again and reassemble the
handle.
