Installation
WARNING: ELECTRIC SHOCK HAZARD!
Installation of this appliance should be performed by
qualified service personnel only. Improper installation
could result in electrocution.
Unpacking Instructions
Carefully unpack the machine and inspect immediately
for shipping damage. The packaging may contain
unattached parts. Your machine was shipped in a carton
designed to give it maximum protection in normal
handling. It was thoroughly inspected before leaving
the factory. In case of damage, contact the shipper, not
Grindmaster-Cecilware.
NOTICE:
This equipment must be installed in
compliance with applicable Federal, State, and/or Local
plumbing codes having jurisdiction. This product requires
an approved back flow prevention water device, such as
a double check valve, to be installed between the
appliance and the water supply. If a check valve type
backflow preventer is used for water supply protection,
a screen of at least 100 mesh (100 strands per 1.0 in [25
mm]) shall be installed immediately upstream. The screen
shall be accessible and removable for cleaning or
replacement. (Required for NSF approved water hook-
up.)
Incoming pressure should be greater than 20 psi and not
more than 90 psi.
• A filtering system is recommended to remove odors
and inhibit lime and scale build up in the unit.
• In areas with extremely hard water, a water softener
must be installed in order to prevent a malfunctioning
of the equipment and in order not to void the warranty.
Unsoftened water will decompose dissolvable minerals
and turn to limescale after boiling. The limescale will
reduce the machine's thermal efficiency and machine's
lifetime.
NOTICE:
Do not use extension cords. Make sure that the
outlet the unit plugs into is grounded. Check rating
marking on nameplate to be sure electric lines match
voltage, phase, and amperage requirements of
appliance.
Venezia II ESP Espresso Machine
Connections
1. When operating the machine for the first time or
replacing water softener and filtration system,
remove the water inlet tube and allow it to drain
for about one minute in order to get rid of
impurities from the water.
2. Connect a 1/2" diameter water line to the water
supply connection.
3. Open the water shut-off valve and check
connections for leaks. DO NOT over-tighten. Verify
water supply.
4. Connect 18mm diameter drain line to bottom,
center of machine.
5. Water pressure:
a.) If filtered water source pressure exceeds 2 bar
and the amount of hot water needed is small, turn
the water inlet motor switch (2) to the OFF (up)
position to permit water inflow without internal
pump assistance (see Figure C).
b.) In areas of low source water pressure, turn the
water inlet motor switch (2) to the ON (down)
position to activate the internal pump and draw
water into the boiler mechanically.
NOTICE
: When source water pressure is low & the
water inlet motor switch (2) in Figure C is turned to the
OFF (up) position, there is the risk of drawing hot water
away from the boiler and damaging the pump and
water intake solenoid.
6. Attach appropriate plug to cord. Power source
corresponds to the electrical rating shown on the
serial tag on unit. Plug the Espresso machine into a
dedicated power supply outlet.
7. a.) Check and confirm that water source is in normal
working order.
b.) Turn the power switch to position I to initiate
automatic system check. If boiler water level is
not in the green zone, wait until the
automatic water replenishment process is
complete before proceeding to the next step.
8. Heating will stop when boiler pressure reaches
approximately 1.2 bars (factory default setting). Do
not operate machine until steam pressure gauge
reading is in the green zone.
