the software of the PC Board has been modified in order to have the possibility to purge
out all the water of the water reservoir every 5 th harvest cycle so to reduce the scale/lime
accumulation into the sump when hard water is used to produce the ice.
To do it, it’s necessary to move the Jumper from the J2 pins to two of the three contacts
of the J1 pins as shown on the here below photos.
All new MV ..6 units are supplied with the Jumper IN on the two J2 pins (MANUAL
RESET Mode) so to assure the best performance of the machine (purged water is “cold”
while water filling up the sump is at tap water temperature)
By moving the Jumper from J2 to J1, the MANUAL RESET Mode is however assured.

WATER LEVEL SENSOR
HARNESS
We would like to inform you that under some very rare circumstances, the Water Level
Sensor of the new MV ..6 series can switch off the water inlet valve with a very low
level of water into the water reservoir (water level corresponding to the longer water
sensor finger).
This can happen when the Water Level Sensor Harness have the two wires connected on
reverse and water is dripping onto the Ice Thickness Sensor at the beginning of the
freezing cycle.
If so, the signal transmitted to the PC Board through
the Ice Thickness Sensor is equivalent to have the
water reservoir full of water tripping OFF the water
inlet solenoid valve.
In this condition the machine operates into the freezing
cycle with a very low level of water tripping OFF 40
minutes later with the Red Alarm Led of the Too Long
Harvest cycle ON.
To overcome the problem the Water Level Sensor
Harness must be replace with the correct one (see
beside drawing and below photo) available under Part
Nbr CM 81455102.

We would like to point you up about the correct setting of the adjusting range screw
used on both the Compressor and Drive Motor Time Delay Part Nbr. EQ DAA51CM
fitted into all MAR units as well as on MF 86/88 control box.
To correctly operate the small arrow of the Range screw MUST be placed in
correspondence of the setting time; in this position, when the Time Delay is in
operation, (start up and trip off of the machine) the small yellow led blinks slow (2
blinks per second).
At contrary, if it’s NOT placed in the correct position, it looks like the Time Delay is
still in operation (yellow led blinks fast – 5 blinks per second) but it’s not through as it
remains all the time in this position w/out energize the Compressor or the Drive Motor

shaft of the auger moving to a bigger one (2,62 mm in place of the current 1,78 mm
chord diameter one, as shown on the here below photo)
OLD
NEW
The larger chord assures an higher friction between the auger shaft and the inner ring of
the bottom bearing so to avoid that the auger shaft can turn free inside the bottom
bearing inner ring with the possibility to worn out the shaft.
The new augers, available under the same part nbrs of the former ones, will be supplied
completed with its larger O Ring and they are perfectly exchangeable with the previous
ones.
The New O Ring, P/N 640041 01 (the same of the one used on AF Ice Breaker) can
NOT be installed on the old augers due to the different size of the groove.

The increase of the friction between the auger shaft and the bottom bearing inner ring may cause some problem in
the withdrawing of the auger from the top of the worm tube/evaporator.
To facilitate the rise up of the auger/ice breaker assy, it’s possible to use two of the four screws securing the ice
breaker to the upper evaporator flange in combination with the two threaded holes using the ice breaker like an
extractor as shown on the photos.
As the auger is supplied with the O Ring pre-installed we suggest you, at time of installation of the upper portion of
the water seal, to remove it in order to avoid any interference with the O Ring located into the S.S. ring as shown
on the here below photos/procedure.

NEW LOCATION OF OPTICAL
ICE LEVEL CONTROL
On the past weeks we have received some field reports about the possible ice bridge
formation over the Optical Ice Level Control used on TCS 180 that, in some
circumstances it can arrive to move out the spout plastic cover with the possibility to
have ice inside the machine.
Test done in our lab proves it mainly when ice is not dispensed for hours (the vibrations
due to the rotation of the dispending vane is more then enough to allow the ice bridge to
fall down into the storage bin).
To overcome the problem we have moved the Optical Ice Level Control inside the
storage bin, as on the old TC 180 version, so to avoid any possible ice bridge formation.
The change/improvement starts from TCS 180 s.n. 5445
To up to date the TCS 180’s in the field we made available a Retrofit Kit at no charge
under Part Nbr 060694 00 consisting off:

ICE THICKNESS SENSOR
Field reports detail us of some possible problems with the setting screw of the Ice
Thickness Sensors used on the firsts MV ..6 series versions.
The setting screw is not properly hold inside the threaded hole of the plastic bracket
with the possibility that vibrations during the operation of the machine can turn it
reducing its distance from the evaporator as well as the thickness of the ice produced.
FOOD PROOF
SILICONE
In this case, the thickness of the ice can become so thin with problem in defrosting it
during the harvest cycle with the machine tripping OFF at too long harvest cycle time.
To overcome the problem we suggest you to remove the setting screw, put some food
proof silicone into the threaded hole and screw it in again.
Just a small quantity of silicone is more then enough to hold the setting screw avoiding
any free rotation due to the vibrations of the machine.

Starting from the serial number 18286 the previous fan motor assy, used on both
versions at 50/60Hz, has been replaced with a new more powerfull one on 60Hz only so
to have a greater air flow and heat removal so to assure a better condensation mainly
when machines are located in warm area.
The new fan motor assy used ONLY on 230V 60Hz machines consists of:
Fan motor P/N 620419 07
Fan blade 620419 34
Fan bracket 620419 65
and it’s exchangeable with the former one only as set.
