FOR THE INSTALLER

The FM1200 is designed to fit the following
Scotsman storage bins:

B590 and extensions (with bin top KBT18)
BH800 using bin top KBT15 (one unit).
BH800 (two units, no bin top required).
BH1000 using bin top KBT16.

When installing a new system, check to be
sure that you have everything you need
before beginning:

Correct Bin
Correct Ice Machine
Correct Bin Top (if required)
All kits, legs, and information required for
the specific job.

Installation Limitations:
This ice system is designed to be installed
indoors, in a controlled environment:

Min

Max

Air Temperature

100

Water Temperature

100

Water Pressure

20 PSI

80 PSI

Voltage

-5%

+10%

(Compared to the nameplate)
Operating the machine outside of the
limitations is misuse and can void the warranty.

The normal finish for the ice machine is
enamel-sandalwood. A stainless steel panel
kit, SPKFM21 may be field installed to convert
the unit to a stainless steel finish.

Note: Minimum Circuit Ampacity is used to determine wire size and type per national electric code.
