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.

Precharged factory line sets, available as optional equipment from Hoshizaki America, are recommended. For details, see "II.F.4.a) Factory Line Set Installation." Field fabricated line sets are allowed. For details, see "II.F.4.b) Field Fabricated Line Set Installation."

The maximum line length for the standard refrigerant charge is 66 feet. Should an installation require a longer line length, line sizes must be increased and additional refrigerant must be added. Instead of the standard 3/8" OD discharge line and 1/4" OD liquid line for this icemaker, increase the line sizes to 1/2" OD discharge line and 3/8" OD liquid line for the entire run. Add 16.5 oz. of R-404A to the system to compensate for the larger diameter line sizes, then add .4 oz. of R-404A for each foot over 66 feet to a maximum of 100 feet. Hoshizaki Technical Support is available at 1800-233-1940 for recommendations.

The maximum vertical distance between the remote condenser unit and the icemaker is 33 feet above or 10 feet below the icemaker. These distances are measured fitting to fitting.

a)Factory Line Set Installation

1)Route the factory line set (3/8" OD discharge line and 1/4" OD liquid line) from the remote condenser unit to the icemaker. Leave a service loop behind the icemaker to allow the icemaker to be pulled out for service. See Fig. 6. Factory fabricated line sets are precharged and do not need to be evacuated.

CAUTION

1.Ensure that there are no traps and no kinks in the line set.

2.Do not coil extra line set. If the line set is too long, recover the line set charge and store it in an approved container. Do not discharge the refrigerant into the atmosphere. Remove the extra line set length, braze the connections, then skip to step 4 in "II.F.4.b) Field Fabricated Line Set Installation."
