Electrical Connection - Wega ALE Series Use And Maintenance Manual

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.
All filling connections are 3/8 male gas type. The drain pan is
connected to a tube with an internal diameter of 16 mm.
If an external tank is used, the connection pipe between the
machine and the tank must not exceed 150 cm.
The machines are equipped with a time-limit switch that allows
the water to fill 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.
FOR THE EUROPEAN COMMUNITY: for the hydraulic connection to
the water mains and also for connection to an external tank, it
is necessary to place a non-return valve (16) up the line from the
machine as set forth by standards EN 1717.
FOR THE U.S.A. - The water connections and discharges must
be made in accordance with the 2003 International Plumbing
Code of the International Code Council (ICC), or with the 2003
Uniformed Hydraulic Code of the IAPMO. The machine must be
installed together with an adequate non-return valve, as required
by national regulations.

Installation must be done in accordance with the
safety standards in force in the country of installa-
tion. The owner/manager of the system must confirm
to the installer that the electrical system meets the
requirements above.
Install a general protection switch
(9) as required by current safety
regulations suitable to the rated
power.
For the electrical connection of the machine, refer to
Chap. "14. ELECTRICAL DIAGRAMS" on page 24.
Do not use power extensions or electrical adaptors for
multiple outlets. If their use is absolutely necessary,
use only simple adapters and extensions complying
with current safety standards. Never exceed the ca-
pacity value indicated on the adapter and the exten-
sion cord, and that the maximum power indicated on
the adapter.
The access spaces to the machine and main switch
must be left clear, in order to allow the user to inter-
vene without any constrictions and be able to leave
the area immediately in case of necessity.
If using an external motor pump, proceed as fol-
lows:
Connect the motor pump cable (with smaller cross
section) to the connector of the external motor as
shown in the diagram below;
connect the machine power cable (with larger cross
section) as set forth in chapter "14. ELECTRICAL DIA-
GRAMS" on page 24.

Always connect the motor pump cable before the machine power
supply cable, in accordance with the diagram provided. Failure
to comply with the instructions given above may cause serious
damage to the machine and/or motor pump and will invalidate
the warranty.
We recommend to promptly report to the Manufacturer any
problems encountered during installation of the equipment.
