• A multipolar switch with at least 3 mm opening should be connected near the
device, and should be easily accessible. This device is designed for switching
the appliance off in the case of installation, repair, cleaning or maintenance work
conducted on the appliance. This switch must be equipped with fuses adjusted
for the rated voltage of the appliance. A properly selected magnetic thermal
switch may be an alternative to the above mentioned switch.
• The appliance must be properly connected to the equipotent bonding circuit; see

Water Connection
Use only hoses supplied with the appliance (never use second-hand hoses).
Before connecting the appliance to the water supply system, the analysis of water
quality should be performed. Manufacturer recommends the following parameters of
water quality:
Water
temperature (T):
max. 60 °C
Total water
hardness
5 °fH (French hardness
degree scale)
pH value:
6.5
–7.5
7 °eH (English hardness
degree scale)
Physical
contamination:
Ø < 0.08 mm
9 °dH (German hardness
degree scale)
Chlorides:
max. 150 mg/l
Conductivity:
400 μS/cm
CI:
0.2
–0.5 mg/l
If the water hardness exceeds 9
°dH (German hardness degree scale), the use of
water softener is required.
Furthermore, when checking the water quality, the pressure of water supply system
must be taken into account. This parameter determines the correct operation of the
appliance.
