Factory Line Set Installation
1) Route the factory line set (5/8" OD suction line and a 1/2" OD liquid line) from the
condensing unit to the icemaker. 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 icemaker first and
then at the condensing unit. 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 5/8" OD copper tube suction line and a 1/2" OD copper tube liquid line between
the condensing unit and the icemaker.
2) Insulate the two copper tubes separately.
3) Install Parker quick connect couplings on each end.
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 icemaker first and
then at the condensing unit. 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.
