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. 3.1. Always
use the flexible hose delivered with the machine, if not present, contact your dealer. In each case do not
use a fixed connection to the water supply.
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.
The machine is equipped with 3/4" inlet valves. First let the water flow from the tap into the drain before
connecting the machine to the water system. This is for cleaning the pipes from dirt. Otherwise the filters
could be stopped up.
Open the taps and check the connection points at the taps and at the inlets of the machine for tightness.
If water is leaking, correct the position of the seal and tighten the screw coupling.
WATER CONSUMPTION
The water consumption depends on the programmed values in the timer. These values are shown in the program
manual. For a prewash and wash the low water level (LL) is used. The high water level (HL) is used for rinsing.
The programmed units correspond to an average amount of water. You can calculate the total water
consumption in one washing program by counting up the amount of water by each washing step.
An example is shown for a system with cold and warm water supply for a machine with capacity of 10kg / 22lb.
A system without warm water supply you can count with the total amounts.

Tab 4.6.B. Water consumption
The values received from this calculation is only an estimation of the real water consumption. The deviation
depends on many circumstances. In the wash cycle for example there will be taken a mix of warm water
and cold water. The mix of the water depends on the temperature of both. The total amount of water consumed
depends also on the loading of the drum with linen and the turning of the drum.
STEAM CONNECTION
WARNING !
BEFORE EVERY STEAM VALVE IT IS NECESSARY TO INSERT THE FILTER WITH PERMEABILITY
UP TO 300 MICROMETERS. POSSIBLE DIRT BIGGER THAN 300 MICROMETERS MIGHT DAMAGE
THE STEAM VALVE AND CAUSE ITS LEAKAGE.
Machines with steam heating have a device for a steam connecting, see fig. 3.1, pos.12) with diameter 1/2“
in rear left part. Use inlet steam pressure hoses, adapted to the valves with seal. The condition for proper function
of inlet valves is the pressure between (0,1 - 0,3 MPa / 14,5 - 44 PSI - applicable for steam pressure low),
(0,3-0,8 MPa / 44-116 PSI - applicable for steam pressure high).
WATER DRAIN CONNECTION
The machine is equipped with a drain valve of 76 mm (3“) diameter. The drain is situated on the rear
of the machine. The drain has to be connected to the waste channel. You can use the elbow, which is a part
of the delivery. Secure the elbow with a clamp.
THE WASTE CHANNEL 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.
