B.

Unpacking and inspection:

Visually inspect the exterior of the shipping
container; any severe damage should be reported
to the delivery carrier.
Uncrate the remote condenser and pre-charged
refrigerant lines and inspect for any concealed
damage. Notify carrier of any cancealed damage.
Check that the pre-charged refrigerant lines are
intact, not kinked.

Remote condenser installation

Install and attach the remote condenser to the
floor or to the wall of the building using methods
and practices conform to the local building
requirements.
Remove the control box cover from the remote
condenser and connect the electrical power line
coming from the unit following the wires colors.
NOTE. Cable connecting the unit to the remote
condenser is at 230 Volts so it is imperative to
have the cable properly protected inside a plastic
or metal tube according to the local electrical
code/standard.

D. Pre-charged refrigerant lines

The set of pre-charged refrigerant lines consists
of the 3/8" O.D. self sealing gas line and 1/4" O.D.
self sealing liquid line both equipped with 1-20"
UNEF AEROQUIP quick connections on MC
16/16 SHORT, MC 46, MF 56, of 12 mm and 8
mm O.D. on MV 450-600 and 14 mm and 12 mm
O.D. on MV 800-1000.
On models MF 66 the pre-charged refrigerant
lines are 1/2" O.D. gas line and 3/8" O.D. liquid
line both equipped with 1-20" UNEF AEROQUIP
quick connections.
On model MF 86 only, 16 mm O.D. gas line and
12 mm O.D. liquid line with AEROQUIP quick
connections too.

refrigerant lines are longer then the distance

keep the excess portion indoor shaped as a
vertical spiral so to avoid refrigerant trapping.
CAUTION. Each coupling on the pre-charged
refrigerant lines is self-sealed and should be
tightened 1/4 turn more then snug tight.
ALWAYS USE
TIGHTENING
BACKUP WRENCH TO PREVENT TWISTING
OF TUBING AND POSSIBLE KINKING OR LINE
RUPTURE.
Connect the gas line coupling to the remote
condenser refrigerant fitting (labeled GAS) and to
the refrigerant fitting on the rear side of the ice
machine.
Connect the liquid line coupling to the remote
condenser refrigerant fitting (labeled LIQUID) and
to the refrigerant fitting on the rear side of the ice
machine.
ATTENTION. The inlet of the remote air cooled
condenser (gas) must be always located
above the outlet (liquid) for both horizontal
and vertical installations.

Operating instructions

The remote air cooled condenser versions of
Cubers and Flakers are operating in the same
way as the standard machine.
The only difference is the operation of the fan
motor on MC and MF series as on the remote
condenser versions it is no longer possible to use
the condenser sensor to control the ON-OFF
operation of the same.
In place of the condenser sensor has been
installed an electronic fan speed control (set up at
16 bar by its adjusting screw) and a manual reset
type hi pressure control.
The fan speed control supplies a variable power
to the fan motor so to modulate its speed and
keep to a constant value the discharge pressure.
The hi pressure control is used only as a safety
device to switch OFF the operation of the machine
in case of fan motor failure.
