flexible hose with silicon cement. Secure the elbow or the hose with a clamp. Cover the waste sump with a
proper cover.
The waste channel must be located lower than the drain outlets because the water discharges from the
machines by gravity. Do not reduce the diameter of the machine drain pipes.
The main waste channel or pipeline must have such a capacity that it can take away the drained water from
all connected machines at the same time. Ask a corresponding expert (construction technician) to design
a sufficiently dimensioned waste pipeline for your washing machines. The correctly designed pipeline is fitted
with the main ventilating pipeline (air supply), possibly an auxiliary ventilating pipeline. This will prevent deceleration
of the flow and creation of a high vacuum or overpressure inside the pipeline, causing a breach of the water level
in odour closures.
STEAM CONNECTION
WARNING!
INSTALL A STEAM SUPPLY DISCONNECTING DEVICE IN THE VICINITY OF EACH WASHER.
DISCONNECT THE STEAM SUPPLY ALWAYS BEFORE ANY SERVICE OR INTERVENTION, GIVING
SUFFICIENT TIME TO COOL DOWN THE PARTS TO AVOID INJURIES.
WARNING!
IT IS NECESSARY TO INSERT A FILTER WITH PERMEABILITY UP TO 300 MICROMETERS IN FRONT
OF THE STEAM VALVE. POSSIBLE DIRT BIGGER THAN 300 MICROMETERS MIGHT DAMAGE THE STEAM
VALVE AND CAN CAUSE ITS LEAKAGE.
For dimensions of steam connection information, see figure 3.3., 3.5 and technical information table.
Use an inlet steam pressure hoses only, adapted to the steam valve with appropriate seal that is suitable for
the applied working pressure. Take care that by the installation and connection of the steam supply the
necessary measure are taken that accidental contact is prevented, this for all persons. Due to the high
temperature, direct injury will appear.
VENTING
WARNING!
VAPOURS ESCAPE FROM THE MACHINE THROUGH THE AIR VENT OPENING!
(figure 3.3., pos.2 and 15, figure 3.5., pos.2 and 7) DO NOT COVER.
The vent air opening is part of the back flow prevention water system. It also takes care that the tub can not be
pressurized by water intake and vapor of the hot water. It allows also proper measuring of the water level.
For the safety of everyone make sure that unauthorized persons cannot reach the backside of the machine.
Notwithstanding the fact that it is not advised and if measures were taken, you can connect the machine venting
pipe to the laundry central duct for exhausting the vapor out of the building. The external diameter of the ventilating
opening for washers 33-40-55 kg / 80-100-125 lb it is 60mm / 2.4“, for washers 80-100-120 kg / 180-230-275
lb it is 40 mm / 1.5“.
For placing of connection points see figure 3.3., 3.5. The piping material must withstand a temperature of 80°C /
176°F and generated machine vibrations. The central duct for multiple venting must be dimensioned for the total
cross section of venting pipes of all machines. Take care that this installation can not create any injury at anyway.
ELECTRICAL
CONNECTION
The machine has been designed for connecting to the power network according the specification of your order.
Before connection check the voltage values and the frequency stated in the machine label if they correspond to
your power network. An individual branch circuit needs to be used for each machine. The way of the
connection is described in figure 4.4.A. For electrical protection, there must be installed a residual current
device (RCD) and a circuit breaker in the electrical installation of the building (laundry switchboard). For
correct selection see below.
IMPORTANT:
– If the machine is not equipped with a main switch then supply disconnecting devices need to be provided
in the installation for all electrical supplies connected to the machine, in accordance with EN 60204-1 standard,
point 5.3.
