Connection To The Water Mains; Water Drain - eka MKF 464 S Translation Of Original Installation And Maintenance Manual

3.10 Connection to the water mains

The appliance must be supplied with drinking water at a maximum temperature of 30°C.
The water pressure must be between 100 and 200 kPa (1.0 -2.0 bar).
If the mains pressure exceeds 2.0 bar, install a pressure reducer upstream of the appliance.
If the value is lower than 1.0 bar use a pump to raise the pressure.
3.10.1 Water inlet for humidification / steam
Exept for mod. MKF 664 SP.
The appliance is equipped with a standardised flexible hose (1.5 metres) with threaded ¾" female fittings
and relative gaskets (Fig. 1). Old joints must not be re-used.
The appliance must be supplied with softened drinking water with hardness between 0.5°f and 3°f. It is
obligatory to use a softener to reduce the formation of limescale inside the cooking chamber.
THE
MANUFACTURING COMPANY DISCLAIMS ANY LIABILITY FOR DIRECT OR INDIRECT DAMAGE CAUSED TO THE
HOOD DUE TO FAILURE TO COMPLY WITH THIS DIRECTIVE.
The connection to the water mains must be set up through the ¾" threaded solenoid valve located on the
back (at the bottom) of the appliance (see the attached "Technical Data Sheet"), using the supplied flexible
hose, with a mechanical filter and stopcock installed in between (before connecting the filter, drain off a
certain amount of water to flush any dirt out of the hose).

Warning
Any damage caused by limescale or other chemicals contained in the water are not covered by warranty.

3.11 Water drain

Exept for mod. MKF 664 SP.
A drain pipe comes out of the rear of the appliance (see the attached "Technical Data Sheet") to drain the
cooking chamber. This pipe must be connected to piping with 30 mm internal diameter (DN 30) resistant
to steam temperatures (90°C-100°C): avoid metal ones.
The piping must be rigid and must not have bottlenecks along the discharge path (it is advisable to use
commercial pipes of special plastic material, with an internal "sealing" O-RING, and to limit the use of
"elbow" bends).
The piping must also maintain a steady slope (min. 4-5%) along its entire length.
The considered length is that of the drain pipe of the appliance to the discharge point and must not exceed
the measurement of 1.5 meters.
It is mandatory to connect the appliance's drain to the grey water network through an adequate trap, in
order to stop steam/odours from coming out of the drain. The connection to the drain water must be set
up separately for each appliance; with multiple appliances connected to the same drain pipe, ensure that
the pipe is suitably sized to assure regular drainage with no hindrances.
