Tab.4.4. A
HOT WATER
When the machine is provided with a hot water inlet, we advise connecting this inlet to a hot water supply
that is set to 70°C – 158°F. The hot water supply needs to be large enough to provide the required hot
water for the washers.
WATER CONNECTION
Most machines are made with 2 or 3 water inlets. One is always marked with „soft water“. If more inlets are
present, they are marked with „Hot water“ or „Hard water“. For connection dimensions see fig. 3.2. – pos. 1,2,3.
Use demountable screw joint for connection to water supply. Be careful that the screw joints of pipeline
do not loose during the connecting!
For the proper function of the machine, it is necessary to keep the water pressure within the limits stated in
the technical data. It is also necessary to connect all available water inlets to a water supply. If a hard water
supply is not present, connect it with soft water. If no hot water supply is present, contact your dealer for the
proper required action.
Inlet valves with an outer thread G1 1/2“ and G 3/4“ for cold and hot water are delivered with the machine.
Connect the water supply pipes to these valves, use the fittings in the connection points to be able to
dismantle the valves (filters) in the case of any failure. The operator must install the manual stop-valve and
the dirt filter into every supply pipe.

WATER DRAIN CONNECTION
Washing machine is equipped with one drain pipe (the second drain pipe for recycle drain can be added per
order) with outer diameter 126 mm (5“) which must be connected to the waste sump. Position see on fig. 3.2.
pos.7. The waste sump must be located lower than the drain pipes because the water discharges from
the machines by gravity. Do not reduce the diameter of the machine drain pipes. To connect the machine
drainage to a waste sump, you can use the flexible hose (part of delivery). Secure the flexible hose with a clamp.
Seal the connecting point of the drain pipe and flexible hose with silicon cement. In same way connect the
flexible hose to waste sump throat, fig.4.3.B.
