CONDENSING AIR FLOW SCHEMATIC

2. Erection - For elevations in excess of four
feet or in close quarters, chain falls of fork lift
truck should be used. For location under four
feet, the use of skid boards and rollers is practical.

3. Machine Site - When selecting the permanent
location of air cooled machines, consideration
must be given to volume size of the room and to
ventilation facilities for easy heat removal around
the machine.
In doing this it worths to take on account that:

– MAR 56 AS - has a condenser heat rejection

of 3000 Kcal/hr and fan motor draws air for
1200 m

3

/h.

– MAR 76 AS - has a condenser heat rejection

of 4900 Kcal/hr and fan motor draws air for
1200 m

3

/h.

– MAR 106 AS - has a condenser heat rejection

of  7500 Kcal/hr and the two fan motors draw
air for 1200 m

3

/h each.

– MAR 126 AS - has a condenser heat rejection

of 9750 Kcal/hr and the two fan motors draw air
for 1200 m

3

/h each.

– MAR 206 AS - has a condenser heat rejection

of 11000 Kcal/hr and the two fan motors draw
air for 2000 m

3

/h each.

– MAR 306 AS - has a condenser heat rejection

of 17200 Kcal/hr and the two fan motor draw air
for 4320 m

3

/h in total.

4. Position the MAR in the selected permanent
location level the cabinet on both the left-to-right
and front-to-rear directions. The levelling legs
can be adjusted with an opened wrench.
(See unit layout and dimensions at page 6 and 8).

10. See DATAPLATE on the cabinet base and

check that the location source voltage
corresponds with the voltage specified on
the dataplate.

CAUTION - Unproper voltage supplied to
the icemaker will void your parts
replacement program.

11. Remove the Manufacturer's registration Card

from its envelope and fill in all spaces
including: Model Number and serial Number
taken from the aluminium plate located on
the front of the Chassis base, with Front
Panel removed.
Forward the completed, self addressed,
registration card to the Scotsman Europe
Frimont Factory.

3. LOCATION AND LEVELLING

WARNING - The MAR Flakers are NOT
designed for outdoors installation where
air temperature are below 5

°

C (40

°

F) or

above 40

°

C (100

°

F) and the water tempe-

rature is below 5

°

C (40

°

F) or above 35

°

C

(95

°

F).

Extended periods of operation at
temperatures exceeding these limitations
will constitute misuse, under the terms of
the SCOTSMAN Manufacturer's limited
warranty coverage.

1. Stands - A special stands should be built if

the machine is located beside the bin.
Care should be exercised in making the
stand strong enough to support the weight.
In designing the stand plan for the servicing
of the machine from front, top and sides.
It is also possible to locate the machine on
top of the bin. Care should be used in selecting
a bin that has been specially reinforced.
Standard bins are usually not sufficiently
reinforced for this purpose. An unsteady
platform will cause excessive vibration.
Specially built bins can provide proper support
and allow for a servicing platform.

WARNING - Air Cooled version of MAR 76,
MAR 106, MAR 126 and MAR 206 have the
condensing air exhaust throughout the
lower rear area (ice spout side) therefore
it is necessary to avoid to position the ice
maker with the rear side against any sort
of wall that will prevent proper warm air
dissipation.They must have on their rear
side an air gap of 200 mm. MAR 56 has the
air cooled condenser on the right side
while MAR 306 has a se-parate remote air
cooled condenser. (See instructions for
remote condenser at 6).
