Electrical Connection - Astoria SABRINA SAE DISPLAY Use And Maintenance Manual

Sabrina
The water mains must provide cold water fit 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 the filling couplings are 3/8 male gas types. The drain tray is
connected to a pipe 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 fitted with a "Timeout" device which allows the
heating unit to be filled up with water within a maximum time.
This function prevents water from flowing out of the heating unit's
valve (flooding) and keeps the motor pump from overheating.
FOR THE EUROPEAN COMMUNITY: when connecting to a water mains
or an external tank, a non-return valve (12) must be positioned
upstream from the machine, as set forth by the EN 1717 standard.
FOR THE USA - The water connections and drains must be made in
accordance with the 2003 International Plumbing Code of the
International Code Council (ICC), or the 2003 Uniformed Hydraulic
Code of the IAPMO. The machine must be installed with a suitable
non-return valve as set forth by the national standards.

The installation must be carried out in accordance
with the safety standards in force in the country of
installation. The owner/ manager of the system must
give confirmation to the installer that the electrical
system meets the above requirements.
Install a main safety switch (8) as set
forth by the current safety regulations
regarding rated power.
To connect the machine to the elec-
tricity distribution system, refer to Chap. 15 on page
61.
Do not use power extensions or electrical adaptors
for multiple outlets. If their use is absolutely neces-
sary, use only simple adapters and extensions which
comply with current safety standards. Never exceed
the capacity indicated on the simple adaptor or ex-
tensions, and the maximum power indicated on the
adaptor.
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 leave the area
immediately when needed.
If an external motor pump is being used, proceed as
follows:
Connect the motor pump cable (the smaller cross
section) to the connector of the external motor as
shown in the diagram below;
Connect the machine's power cable (the bigger cross
section).

machine and/or motor pump and will invalidate any guarantee.
We recommend that you promptly report any problems
encountered during the installation of the appliance to the
Manufacturer.
