3. Installation
1) Accessories
Check the package to make sure that the following
accessories are included:
•
a number of 1-dose and 2-dose portafilters
corresponding to the number of groups;
•
replacement 1-dose and 2-dose filters (one of each)
•
1 tamper
•
1 blind filter
•
cleaning detergent, for the groups
•
3 stainless steel braided hoses for water connections
•
1,5 mt of reinforced plastic tubing for drainage
•
1 hose clamp
In order to proceed with installation, it is necessary that the
following are available:
a) Pipes carrying drinking water with a 3/8"G (BSP) end
connection; (3/8" Compression for USA and Canada)
b) Electrical Supply according to the specification of the
espresso machine purchased:
• Single/Three phase 220VAC - 50/60 Hz electrical
connection with ground, protected socket and approved
interlock switch
• Single phase 200VAC - 50/60 Hz electrical connection with
ground, protected socket and approved interlock switch
• Three-phase, 380VAC - 50/60 Hz electrical connection with
neutral + ground, near the bench on which the machine is
installed and terminating in a suitable protected fivepole
socket equipped with an approved interlock switch
c) Waste water drain system
NOTE:
The drinking water stopcock and the terminal switches for the
electrical system need to be located in the most convenient
position for the operator to access them easily and quickly.
2) Water Supply Connection
Connect the inlet of the water filter/softener to the drinking
water supply using one of the supplied stainless steel
braided hoses. Before connecting the water pump to the
espresso machine, flush the water supply line and the
filtration system in order to eliminate any residual particles
which could otherwise get stuck in taps or valves thus
preventing them from working properly.
Connect the water supply connection of the espresso
machine to the water pump outlet using one of the supplied
stainless steel braided hoses. Then connect the water
pump inlet to the water filter/softener outlet.
NOTE: The water pump is differential pressure, volumetric
pump and has been designed to be used exclusively with
cold water. Make sure that water is always present while the
pump is operating, otherwise air can be introduced into the
brew boiler causing an undesireable condition.
3) Electrical Connections
a) Power Supply Cord
This is the main power supply cable that provides power to the
entire espresso machine. There are different types of cable
based upon the electrical requirements of the espresso
machine purchased
•
200/220VAC 1 Phase 3-core cable with 2.5/4/6/10mm
2
cross section or AWG 12/10/8 (for UL version), secured to
espresso machine via a strain relief connector
•
220VAC 3 Phase 4-core cable with 4 mm
2
cross section
for versions with 1, 2 , 3 and 4 groups secured to espresso
machine via a strain relief connector
•
380 VAC 3 Phase 5-core cable with 2.5/6 mm
2
cross
section for versions with 1, 2, 3 and 4 groups secured to
espresso machine via a strain relief connector
b) Water Pump Motor Power Cord
This is the power supply for the water pump motor. The internal
electronics will switch the pump motor on when needed.
•
3-core cable with 1.5 mm
2
cross section or 3-core AWG
16 (for UL version) secured to espresso machine via a strain
relief connector
3) Waste Water Drain Connection
The espresso machine drain is to be connected by means of
the included reinforced plastic tubing. Connect one end of the
reinforced plastic tubing to the drain hose connection on the
left side of the espresso machine, secure with included hose
clamp. Connect the other end to a suitable waste water
collection system. In case such a system is not available,
drained liquids may be collected in a suitable bucket and any
necessary drain pipe extensions shall be made using steel-
lined PVC tubing and suitable hose clamps.
HAZARDOUS VOLTAGE DISCONNECT FROM
POWER SUPPLY BEFORE SERVICING
The manufacturer declines any responsibility for any event
leading to liability suits whenever
has
according to current local, national,
and international regulations and electrical codes, or other
electrical parts have been connected improperly.
GROUNDING
NOT
BEEN COMPLETED
Before making any electrical connections make sure
that the 2 strain relief connectors are firmly secured to
the body of the machine in order to prevent inadvertent
stress on the power cables.
