Electrical connection EZ + Potential equalisation PE
Do not connect the unit to the mains if it has just been transported from a cold
environment into a warm room. Otherwise condensate may develop inside the combi
steamer which may cause damages.
Wait for about two hours until the unit has reached room temperature.
Electrical connections must be performed by an approved electrician in accordance
with VDE regulations and regulations of the local electricity supply companies.
yAs standard the unit with 5,9 kW is supplied with a connecting cable, length 2 m. In case this
cable has to be replaced for whatever reason, use a cable type H07RN-F according to
German VDE standards.
yThe unit with 3,6 kW is ready for plugging
yNext to the appliance an all-pole electric circuit breaker with a contact opening of at least
3mm has to be provided for on site.
yEvery unit requires its own connection and fuse protection.
yModel B: Upon request the possibility of connection to energy optimising systems is
provided for.
yModel C: The possibility of connection to energy optimising systems is standard.
Connecting data:Standard
Connected load 5,9 kW 3,6 kW
Voltage 400 V 3N AC 230 V AC
Fuse protection 3 x 16 A 1 x 16 A
yRefer always to data given on the type plate.
yThe appliance must be incorporated into the potential equalisation system (ground).
You find the terminal under the indication plate.
Water supply EWk /TWk
Connection to the drinking water supply in accordance with the German standard
DIN 1988, section 4 .
yIn accordance with DVGW instructions (German Gas and Water Standard), the appliance is
intrinsically safe and can be connected to the drinking water supply without additional
preventive measures.
To avoid calcareous deposits, we recommend to install a water softener on the basis of
decarbonizer / osmosis for the steam production, if the water hardness exceeds 6° dH (1,08 mmol/litre).
Physical methods, such as for instance magnetic fields are unsuitable.
Please observe installation and operation instructions for the water softener.
Do not use any connections of galvanized steel or any similar material sensitive to corrosion
between water softener and the unit.
yAs standard, the appliance is equipped with two water supply connections (EWk /TWk), both
must be connected.
ySoft water connection EWk for steam generation and manual humidification.
yHard water connection TWk (cold water) for cooling down the condensed water.
(Warm water results in increased water consumption, hot water would stop cooling down)
yWe recommend to use a pressure-resistant, flexible hose ½ " with R¾" screwing. It should be
DVGW (German Gas and Water Standard) and drinking water approved. Make sure it is long
enough to remove the appliance by approx. 50 cm from its standard position ensuring easy
access for servicing .
