If we are 100% sure that the supply of
electric power is off we unscrew the
screws on the hatch of the electric
resistance (
43
). The thermostat (
28
)
which is connected to the electric resistance
(
33
) is already adjusted to
60ÆC
. If you need
you can change the temperature levels yourself by
using the temperature regulator (
30
), but we
recommend not setting it more than
75ÆC
. The thermal security
switch (
29
) in order to be activated the
red
button must be pressed.
As long as we have inserted the electric cable (
41
) from the slot of the protection hutch for the electric resistance (
43
), we
connect the cables on the conductor joint (
34
) and we place them at the correct position as shown at the electrical diagram.
Then we screw the terminals of the electric cables very well in order to avoid any sparking such as
L = power – N =
Neutral
= earth
, and when we are sure that we have made the correct installation we place and screw the hutch (
43
) back to its
position.
Notes:
ñThe power of the electric resistance is 4000W – 230V
ñThe electric installation must be made only by a licensee electrician
ñThe electric resistance can be delivered with copper tube coil for external thermal source upon request (
39
)
ñDon’t ever use the electric resistance if the water tank is empty because it will be destroyed.
