TEST connector closed
G JUMPERS
The Flaker PC Board is equipped by six jum-
pers:
J1 = PURGE Used on machine equipped with
Water Purge Valve to purge out the water from
the water system every 12 hours and when the
machine restart from the Bin Full
JUMP IN - Purge OFF
JUMP OUT - Purge ON
J2 = PWD Used to Pump Out the water by
means of the Progressive Water Pump supplied
as a kit
JUMP IN - No Progressive Water Pump
installed/in operation - MF Models
JUMP OUT - Progressive Water Pump
installed/in operation
J3 = 3’/ 60’ Delay time at start up
JUMP IN - 3 minutes delay
JUMP OUT - 60 minutes delay
J4 = TEST Factory use ONLY
J5 = 6/12 MESI Cleaning remind for the water
system - Red Light blinks/flashes with machine
ON
JUMP IN - 6 months set up
JUMP OUT - 12 months set up
NOTE. To restart the cleaning remind
countdown push and hold the PC Board
button for more of 5 seconds with machine in
operation till the switching OFF of the two
YELLOW Leds.
J6 = 60/70 °C Set up of the Safety Condensing
Temperature Sensor
JUMP IN - 70°C
JUMP OUT - 60°C
H. INTERFACE P.C. BOARD
(Only on SFN1000)
Used only on SFN1000 model, it allows to ela-
borate the signal received from both the elec-
tromagnetic sensors as well as from both the
optical ice level controls transmitting it to the
P.C. Board for the control of the unit operation.
The Interface P.C. Board is equipped by four
INLET sockets (two for the electromagnetic sen-
sors and two for the optical ice level controls)
and two OUTLET plugs to be connected to the
sockets of the main P.C. Board.
I FLOAT RESERVOIR
The float reservoir consist of a plastic water pan
on which is fitted a float valve with its setting
screw. The float valve modulate the incoming
water flow to maintain a constant water level in
the reservoir, level that corresponds to the one
in the freezing cylinder to ensure proper ice for-
mation and fluidity.
On the inner side of the reservoir cover are fit-
ted the two water level sensor pins which
detects the presence or the shortage of water in
the reservoir.
NOTE. It is very important to make sure of the
correct fitting of the cover on the reservoir in
order to enable the sensor to efficiently control
the water situation avoiding undue shutoff
interventions.
