1. The phase monitor is preset to 208 Vac from the factory.
2. If building voltage is less than 208 Vac, consult technical service.
3. See below chart for phase monitor diagnostics.
PLEASE NOTE THAT ANY TIME POWER IS APPLIED TO THE CONDENSING UNIT, OR THE
UNIT COMES OUT OF A FAULT STATE, IT WILL TAKE APPROXIMATELY 200 SECONDS FOR
THE UNIT TO POWER ON.

3.1
CAUTION
• The installer of the refrigeration line set must be USA Government Environmental Protection Agency
(EPA) certied in proper refrigeration handling and service procedures
• A qualied person must perform all roof or wall penetration
• Do not form unwanted traps in refrigeration lines. A service loop is not considered an oil trap.
• Never coil excess refrigeration tubing
• The compressor oil rapidly absorbs moisture. Minimize the exposure of the refrigeration system by not
releasing the condenser unit or evaporator unit holding charge until all line connections are nished
and the system is ready for evacuation.
WARNING
• This unit contains a full charge of R449A.
1. Make and connect line set run from the condensing unit to the evaporator unit with all
specications found in the installation specications section. Do not overheat shut off valves on
the condenser unit or evaporator unit.
Note: Insulate entire suction line (not the liquid line) including shut off valves to prevent
condensation.
2. Leak check eld joints via the evaporator unit service valves.
3. Evacuate line set via the evaporator unit service valves.

Note: Condensing unit shipped fully charged with 8 lb R449A.
5. Ensure all valves are open on condensing unit and ice machine.
9. Turn on power to condensing unit and evaporator unit.

24 Vac signal wire
Run 24 Vac signal
wire to connector,
then plug connector
into socket at ice
machine.
Ice Machine
Outdoor Condensing Unit
Run 24 Vac signal
wire to TB2 terminals
1 and 2 of condens-
ing unit.
The low voltage control (24 Vac signal wire) must be run and connected at the back of the ice machine
and to the condensing unit. Route low voltage wire through the upper knockout at the condensing unit
and secure with appropriate connector per NEC.
Follett suggests the following wire for the ice machine signal wire (2 conductor, 18 gauge thermostat
wire), but be sure to follow NEC guidelines:
Southwire: 553020507, Johnston Supply: G80-220, United refrigeration: UL1825
