Hydraulic Connection (With Hydraulic Connection Available) - Wega Mininova Use And Maintenance Manual For The Technician

3.2
Hydraulic connection (version with
hydraulic connection available)
If the machine is available to be connected up to the
water, follow the instructions below:
1.
Connect the water supply (10) to the softener inlet
(7) using the provided flexible hose;
2.
connect the softener outlet (6) to the external motor
pump inlet (8);
3.
connect the outlet of the motor pump (9) to the
inlet of the machine (4);
4.
connect the drain pad of the machine (2) to the
sewer discharge (3) using the special hose provided,
avoiding overly tight bends or kinks, and making
sure that there is sufficient inclination for water to
drain.

Warnings
1.
The water supply must provide cold water for
human consumption (potable water) at a pressure
between 1,5 and 5 bars. If the pressure is higher than
5 bar, connect a pressure reducer before the pump.
2.
add a tap (11) to the water supply so as to stop water
from flowing to the machine;
3.
in order to prevent damage, it is advisable to install
the softener where it will be protected from accidental
blows;
4.
to prevent water from freezing, install the softener
inside a premise with a room temperature higher
than 5°C;
5.
if there is no softener, connect the water supply (10)
directly to the inlet of the external motor pump (8);
6.
if there is an internal motor pump, connect the outlet
of the softener (6) (if there is one) or the water supply
(10) directly to the machine inlet (4);
7.
when connecting the pad of the machine to the sewer
drain, avoid overly tight curves or kinks, and make
sure that there is sufficient inclination for water to
flow out of the drain;
8.
the drain must be connected to an inspectable siphon
that can be periodically cleaned, in order to avoid
bad odours;
9.
to avoid oxidization and damage to the machine over
time, do not use iron connections for the hydraulic
system, even if galvanized.

All filling connections are 3/8 male gas type. The
drain pan is connected to a tube with an internal
4
diameter of 16 mm.
5
All of the machine are equipped with a "Time-out"
6
device that allows filling of water in the boiler
within a maximum time. This function keeps water
i
from flowing out of the boiler's valve (flooding)
7
and keeps the motor pump from overheating. If
the time limit is not enough for the boiler to fill
up completely (such as for the machines installed
with 3 or 4 groups), turn the machine off and then
back on, and repeat the operations listed above.
