Electric Oven rev. 6 ______________________________________________________EKF 1021 UD – EKF 621 UD
Connection to the water mains - The oven must be supplied with softened drinking water with
a hardness value of 0.5 to 3°F (It is obligatory to use water softener to reduce the formation of
scaling inside the cooking chamber). The water pressure must be in the range of 100 to 200 kPa
(1.0 – 2.0 bar). If the water pressure exceeds 2.0 bar, install a pressure reducer device upstream.
If the pressure is below 1.0 bar, use a pressure pump to increase the level.
The connection to the water supply is done using the " threaded solenoid valve on the back
¾
(at the bottom) of the appliance (see fig. 1), fitting a mechanical filter with a cut-off cock
(before connecting the filter, allow a certain amount of water to flow out in order to remove
any waste from the pipe).
Water drainage - A drain pipe (see Fig. 1) comes out from the rear of the appliance, to drain the
oven cavity. This pipe must be connected up to a pipe made to resist steam temperatures (90°C-
100°C) with an internal diameter of 30 mm (DN 30). To prevent choking, it is best to use a rigid
pipe and make sure there are no "elbow" bends anywhere along the drain line.
Furthermore, the drain line must slope down (minimum slope 5%) along its full length (the
length in question is from the appliance's drain pipe to the drain point and must not exceed 2
metres). The drain line must run into an open floor drain (Fig.2). In addition, there must be a
free air gap of at least 25 mm (distance between the drain line coming from the appliance and
the funnel on the drain standpipe). Whatever the case, in order to comply with current hygiene
standards, the line connected to the appliance's drain pipe must not come into direct contact
with the drain point. It is advisable to include a suitable trap in the line connecting the
appliance's drain outlet to the grey water waste system, thus stopping the steam coming back
out of the drain.

Connection of power cable - To reach the power terminal board remove the left side of the
appliance. Loosen the cable-clamp on the back (at the bottom) of the appliance (see Fig. 1) and
pass the cable through up to near to the terminal board. Locate the leads against the terminal
board so that the earth lead is the last to detach from its terminal in the event of reverse
pulling. Connect the 3 phase leads to the terminals marked "L1" "L2" and "L3", the neutral
lead to the terminal marked "N" and the earth lead to the terminal marked as shown in the
following layout:
(this electrical connection layout is also available near the power supply terminal board). Tighten
the cable clamp on the back (at the bottom) of the appliance and replace the left side. The
cable must correspond to those given in the "Technical specifications" table (paragraph 1.1).
