The manufacturer decl nes all l ab l ty for d rect or nd rect njury or damage der v ng from fa lure to comply w th these
regulat ons. Before nstallat on, check that there are no objects or mater als near the mach ne wh ch may be damaged by steam
or splashes of wash ng solut on, or that such tems are su tably protected. Place the d shwasher n the chosen po nt and remove
the protect ve f lm. Level the d shwasher (w th the a d of a sp r t level) on ts adjustable feet to ensure that t s stable; all other
mount ng solut ons must be approved by the manufacturer.
4INSTRUCTIONS FOR TECHNICAL STAFF
4.1 Plumbing hookup
PLUMBING HOOKUP
The water p pel nes and electr c ty supply cable lead out of the bottom r ght-hand corner of the appl ance.
Connect the water ntake hose to a connector w th ¾” ga threaded f tt ng, f tt ng the f lter A prov ded ( n
models w th Acquastop, the f lter and r ng-nut form a s ngle un t). The connect on to the water ma ns must
only be made w th new hoses; the use of old or worn hoses s not perm tted.
The dynam c water upply pre ure must be between 1 and 6 bar (accord ng models); f t s h gher, nstallat on of a pressure
reducer s necessary. If the pressure s le than 2.5 bar (models w thout r nse pump) t m ght be necessary to f t a spec al pump
on the appl ance to ensure opt mal performance. Contact the After-Sale Service. It s essent al to f t a ma n stop tap on the
water ntake del ver p pel ne; the tap must be access ble after nstallat on of the appl ance, so do not nstall t beh nd the
d shwasher. The stated cycle durat on appl es to appl ances suppl ed w th hot water >50°C<60°C. If the d shwasher s suppl ed
w th cold water, the cycle durat on m ght ncrease depend ng on the ntake water temperature. Drainage: The d shwasher i
fitted with a drain pump and can operate w th dra n connect ons on the floor or wall. Refer to the connect on d agram for the
max mum perm tted he ght of wall dra ns – (see TECHNICAL DATA)
Warning: make sure that the ntake and dra n hoses are not bent, constr cted or crushed after nstallat on.

7
When nstall ng the dra n hose to a s phon w th valve, the max mum he ght of the dra n outlet s reduced to 600 mm.
4.2 Electrical connection
The di hwa her and any add t onal equ pment mu t be connected to the electrical y tem by author sed,
sk lled staff, n accordance w th the relevant regulat ons; also comply w th the techn cal nstruct ons for the
connect on. The total rated power s stated on the appl ance’s techn cal data plate. The electr cal protect on
dev ces f tted for the d shwasher must serve th s appl ance only. The user must have a ma ter witch and a
differential afety breaker, with rating uitable for the appliance’ characteri tic , nstalled on the electricity
upply line n accordance w th the relevant regulat ons. These sw tches must be nstalled close to the
d shwasher, be eas ly access ble after nstallat on, and prov de complete d sconnect on from the electr cal
ma ns n overvoltage class III cond t ons.
Warning!
The d shwasher s always powered up unless the master sw tch s turned off.
Connect the appl ance to the user’s earth system. The term nal for the connect on s n the bottom r ght-
hand corner of the appl ance. The earth w re (PE) s yellow-green n colour, the neutral w re (N) s blue and the
l ve w res (L1, L2, L3) are black, grey and brown. In the event of s ngle-phase connect on (230V-1N~), the
connect on to the electr cal ma ns mu t be made us ng a cable w th plug compliant with the relevant
regulation .
Accord ng to the target market, the d shwasher can be equ pped w th a cable fitted with plug.
THE POWER SUPPLY CABLE, IF FITTED, MUST BE REPLACED BY THE MANUFACTURER OR AN AUTHORISED
SERVICE CENTRE IN ACCORDANCE WITH THE TECHNICAL DATA SPECIFIED ON THE WIRING DIAGRAM
SUPPLIED WITH THE APPLIANCE, TO PREVENT ALL RISKS.
5FIRST START-UP
Fir t tart-up
The electr cal protect on system must undergo a funct onal test before the appl ance s put nto operat on.
The appl ance must be nstalled and/or nspected by qual f ed staff, who w ll start t up for the f rst t me and prov de the
relevant operat ng nstruct ons.
Preparing for u e (important)
The r nse a d d spenser s f tted on all models, the detergent d spenser only on some.
If both di pen er are present put the external detergent and r nse a d conta ners n place and nsert the respect ve ntake
hoses on the rear of the appl ance nto them. Red hose: detergent, blue hose: r nse a d
Before nsert ng the hoses nto the conta ners, f t the we ghts (needed to ensure that they always draw n
l qu d from the bottoms of the conta ners) and the f lters onto the r ends as shown. If the detergent d spenser
s not factory-f tted, t can be retrof tted after order ng the relat ve k t.

8
IMPORTANT
Whenever the type of detergent or r nse a d s changed, t s ABSOLUTELY ESSENTIAL to flush out the per stalt c pumps by
plac ng the external ntake p pes n water for a few cycles. Always use only products spec f cally recommended for use n a
profess onal d shwasher. Fa lure to comply w th th s recommendat on leads to forfeiture of the warranty ent tlement on the
appl ance’s water system. Replacement of the internal tube of the detergent and r nse a d per stalt c pumps s recommended
every 12 month or 15.000 wa h cycle , by the After-Sales Serv ce.
5.1 U ing the water oftener (on model with thi feature only)
The quant ty of l me n the water (wh ch nd cates ts hardness) causes wh t sh marks on dry d shes and d shes
also tend to lose the r sh ne over t me. The d shwasher s equ pped w th an automat c water softener wh ch
removes the substances that cause hardness from the water w th the a d of regenerat ng salt.
The f rst t me the d shwasher s used, a l tre of water must be poured nto the tank w th the salt. Whenever the
tank s f lled, always take care to ensure that the cap s f rmly closed. The m xture of water and detergent must
not get nto the salt tank, as th s would mpa r operat on of the regenerat on system. In th s case warranty
cover w ll be forfe ted.
