Factory Line Set Installation

1)Route the factory line set (1/2" OD discharge line and 3/8" OD liquid line) from the remote condenser unit to the icemaker. See Fig. 6. Factory fabricated line sets are precharged and do not need to be evacuated.

Note: Care should be taken that the icemaker, line set, and remote condenser unit contain the same type of refrigerant prior to making connections. Mixing of refrigerants will result in improper operation and possible damage to the refrigeration system.

2)Attach the refrigerant lines to the appropriate male couplings on the remote condenser unit first and then at the icemaker. Apply two drops of POE oil to the male threads of the couplings before tightening.

3)Tighten the couplings 1/4 turn beyond fully seated. A backup wrench is recommended.

Field Fabricated Line Set Installation

1)Route a 1/2" OD copper tubing discharge line and a 3/8" OD copper tubing liquid line between the remote condenser unit and the icemaker. See Fig. 6.

2)Insulate the two copper tubings separately.

3)Install Parker quick connect couplings on each end. OS-QUICK, a universal quick connect coupling kit available as optional equipment from HOSHIZAKI AMERICA, is recommended.

4)Evacuate through the charging ports on the Parker quick connect couplings and charge with R-404A refrigerant vapor to a pressure of 15 to 30 PSIG.

Note: Care should be taken that the icemaker, line set, and remote condenser unit contain the same type of refrigerant prior to making connections. Mixing of refrigerants will result in improper operation and possible damage to the refrigeration system.

5)Attach the refrigerant lines to the appropriate male couplings on the remote condenser unit first and then at the icemaker. Apply two drops of POE oil to the male threads of the couplings before tightening.

6)Tighten the couplings 1/4 turn beyond fully seated. A backup wrench is recommended.
