PLUMBING CONNECTIONS

1. All plumbing lines and connections must conform to local and national plumbing codes.
2. Line shut-off valves must be located in supply water lines for cuber and condenser if product is wa-
ter-cooled. Water supply to water-cooled condenser must include a stand-pipe to prevent "water
hammer".
3. Should your local water supply quality require the installation of a water filter system, consult your
local distributor or dealer for proper size required.
4. Water supply pressure must not be lower than 20 PSI (1.37 BAR), nor should it exceed 80 PSI (5.52
BAR).
NOTE: Water filters larger than 5 microns do not give proper protection.
NOTE: Bin and cuber drain lines must never be connected together and must be vented.
NOTE: Always flush inlet water lines 1–2 minutes before connecting to Ice Maker.

ELECTRICAL

1. All wiring and connections must conform to national and local electrical codes.
2. Wire size and circuit protection must conform to specifications and cuber must be on a separate
electrical circuit.
3. Strain relief connectors must be used at the junction box of the control box and the cuber.
4. Cuber must be grounded by the control box ground screw or other method for intentional safety
grounding that meets code requirements.
5. A manual disconnect in a convenient location to the cuber must be installed.
NOTE: See Remote Condensers, Install Instructions.
NOTE: All HP-62 (R404A) ice machines have a voltage range of –5%, +10% from the serial plate
rating.

INSTALLATION CHECK POINTS

1. Has bin and cuber been leveled and sanitized?
2. Does electrical and plumbing meet code requirements?
3. If water-cooled, are inlet and drain connections to condenser correct?
4. Are drain lines separate and vented?
5. Is there a 6I clearance on the right and back side for proper air circulation?
6. Does the water curtain move freely? Does the inlet solenoid valve shut off incoming water to
the water pan?
7. Has the unit been properly sealed to the bin or dispenser?
NOTE: A 6" top clearance will improve service accessibility.

START UP AND CHECK OUT

Start Up Sequence

1. Check all connections.
2. Turn on the main power switch. The red LED will flash 6 times then remain on for 4 seconds.
3. The unit will go through a 45 second hot gas defrost to remove any ice that might be on the
evaporator.
4. There will be approximately a (45) second evaporator pre–chill, then the water pump will start,
and the freeze cycle begins.
