5. Refrigerant Charge (Line Set Exceeding 66 Feet)
CAUTION
The icemaker, line set, and remote condenser unit must contain the same
type of refrigerant. Mixing of refrigerants will result in improper operation and
possible damage to the refrigeration system.
The maximum line length for the standard refrigerant charge is 66 feet. Should an
installation require a longer line length, additional refrigerant must be added. Add 0.4 oz. of
R-404A for each foot over 66 feet to a maximum of 100 feet. Hoshizaki Technical Support is
available at 1-800-233-1940 for recommendations.
After weighing in the additional charge, mark the unit’s nameplate to show the new correct
total refrigerant charge.
6. Electrical Connection
WARNING
1. Electrical connection must meet national, state, and local electrical code
requirements. Failure to meet these code requirements could result in death,
electric shock, serious injury, fire, or severe damage to equipment.
2. THE REMOTE CONDENSER UNIT MUST BE GROUNDED. Install a proper
ground wire from the icemaker to the remote condenser unit. Use wire of an
appropriate gage and outdoor rating. Failure to properly ground the remote
condenser unit could result in death or serious injury.
3. Install line and neutral wires from the fan motor leads in the icemaker to the
leads in the remote condenser unit junction box. Use wire of an appropriate
gage and outdoor rating.
4. Do not connect the fan motor leads in the icemaker to incoming power
source. Do not connect the fan motor leads in the icemaker together. Do not
allow the leads to contact the junction box walls.
5. Do not connect the remote condenser unit to an external power source.
6. To reduce the risk of electric shock, make all remote condenser unit
connections before connecting the icemaker power supply.
7. The icemaker should have power for a minimum of 4 hours prior to startup to
prevent compressor damage.
• Usually an electrical permit and services of a licensed electrician are required.
• The opening for the power supply connection is 7/8" DIA to fit a 1/2" trade size conduit.
