Scotsman MAR 106, Service Manual

Page: 15 / 42

CAUTION - DO NOT kink or crimp the
refrigerant lines.
DO NOT bend excess refrigerant lines in
a vertical loop (s), which allow trapping
of refrigerant in LOW sections during
OFF time.
Bend and shape excess refrigerant lines
in VERTICAL spirals, not HORIZONTAL
spirals. See Figure above.
7. ICE LEVEL CONTROL
The MAR flake ice system are equipped with
and adjustable thermostatic control that cuts off
ice making operation when its sensing bulb gets
in contact with the ice deposited in the storage
bin. The temperature range dial goes from +10
°
C
to -35
°
C and its long capillary (3.5 m.) attaching
the liquid filled bulb, should be conveniently
positioned in the storage room at the desired
height by holding it with an appropriate bracket
to be arranged in accordance with the location
possibilities. These controls may or may not be
used, it depends of storage room arrangement
and its inner temperature that must be higher,
anyway, to that of the ice produced.
In case of a prevailing low themperature (below
-20
°
C) created by the sub-cooled ice that is
staging above the ice level, which will prevent a
positive function of the ice level thermostatic
control, the thermostatic sensing bulb must be
removed from the storage room.
The MAR ice system are also equipped with a
timer which allows to present the system
operations time in relation to the quantity (level)
of the ice desired. This timer function takes
place of the ice level control.
8. ICE CHUTE
Mar compact unit are supplied with its own ice
chute. In addition optional kits for various
solutions are available on request.
9. FINAL CHECK LIST
1. Is the cabinet level 3 (IMPORTANT).
2. Have all electrical and piping connections
been made?

6. Have the compressor hold down bolts been
en checked to be sure the compressor is floating
on the mounting springs?
7. Has the owner/user been instructed on how

mail the completed card to the Frimont Scotsman
Europe Factory.
9. Check all refrigerant lines and conduit lines,
to guard against vibration or rugging and possible
failure.
10. Is the cabinet in a room where ambient
temperatures are a minimum of 5
°
C (40
°
F) all
year around?
11. Has water supply pressure been checked to
insure a minimum of 1 bar (14 psi) and max of 5
bar (70 psi)?
12. Has the owner been given name and
telephone number of the authorized SCOTSMAN
Service Agency serving him?

4 hand shut off valve
5 Water filter
6 Water supply in.
(Run separate water inlet
for condenser)
