• If needed, carry out an equipotential bonding,
using the screw placed on the rear of the machine
below the frame and marked with the symbol
shown to the left.
• Make sure that the cold water supply line intended
for condensation has pressure values between 1
and 3 BAR (between 100 kPa and 300 kPa) and
temperature between 13°C (55°F)
(68°F) .
• Connect the cold water supply pipe intended for
condensation onto the machine inlet as shown in
the figure. Use a Ø1/2" fitting and place a gate
valve in the operator's reach.
• Connect the condensation water drain pipe onto
the machine outlet as shown in the figure, using a
Ø1/2" fitting.
• Always use new pipes suitable for hot water and
for pressure up to 10 bars both for delivery and
draining. Never use worn or consumed piping. Use
suitable DIN 3017 hose clamps.
• The drain pipe must have an inclination of at least
3 cm (1-3/16") for each 100 cm (39" of length).
• After having connected the water inlet and outlet
pipes, with the machine stopped, open the cut-off
cock and make sure that water does not leak from
the drain.
• Turn off the master switch and press the
PRODUCTION button to check the following:
1. Condensation pressure (water models only).
With the machine in production mode, after a
few seconds condensation water must come
out of the drain pipe at a temperature of about
35°C (95°F). If this is not the case, the pressure
switch valve shown in the figure must be
adjusted.
