Hydraulic Connection - Wega Concept Use And Maintenance Manual

3.2

Hydraulic connection

• Remove any rubber plugs which may be inserted in
the tap fi xtures of the softener;
• connect the water supply (
(10) using the provided fl exible hose;
• rinse the resins from the softener and check that the
water, which initially comes out yellowish, comes
out clean;
• connect the softener outlet (
pump inlet (13);
• connect the outlet of the motor pump (
of the machine (7);
• connect the drain pad of the machine (
discharge (5) using the special hose provided, avoid-
ing overly tight bends or kinks, and making sure that
there is suffi cient inclination for water to drain.
!
All filling connections are of the 3/8 male gas
type. The drain pan is connected to a tube with an
internal diameter of 16mm.
The water supply of the appliance must be carried
!
out with water which is suitable for human
consumption, in compliance with the regulations in
force in the place of installation. The installer must
receive, from the owner/manager of the system,
confi rmation that the water meets the above listed
requirements.
During the installation of the appliance, only
the components and materials supplied with the
appliance are to be used.
!
Should the use of other components be necessary,
the installer must verify their suitability to
be used in contact with water used for human
consumption.
The installer must carry out the hydraulic
connections in accordance with the hygiene norms
and the hydraulic safety norms for environmental
protection in force in the place of installation.
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.
Technical manual
12) to the softener inlet
11) to the external motor
14) to the inlet
6) to the sewer
2.
add a tap ( 15) to the water supply so as to stop water
from fl owing 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
(12) directly to the inlet of the external motor
pump (13);
6.
if there is an internal motor pump, connect the
outlet of the softener (11) (if there is one) or the
water supply (12) directly to the machine inlet
(7);
7.
when connecting the pad of the machine to the
sewer drain, avoid overly tight curves or kinks, and
make sure that there is suffi cient inclination for
water to fl ow 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.
The hydraulic connection must be made in
compliance with local national standards. In case
!
of use of an external tank: the connection hose
between the machine and the tank can't be longer
than 150 cm. For the European Community: both
for the hydraulic connection to the water supply,
and for the connection to an external tank, it is
necessary to place a non-return valve (15) on the
machine as set forth by EN 1717 standards.
The machines are equipped with a time-limit
switch that allows the water to fi ll the boiler only
!
for a limited time. This function keeps water from
flowing out of the boiler's valve (flooding) and
keeps the motor pump from overheating. If the
time limit is not enough for the boiler to fi ll 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.
