Factory Line Set Installation
1) Route the factory line set from the condensing unit to the icemaker. Factory fabricated
line sets are precharged and do not need to be evacuated.
) Attach the two refrigerant lines to the male couplings on the remote condensing 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 5/8" OD copper tubing suction line and a 1/" OD copper tubing liquid line
between the condensing unit and the icemaker.
) Insulate the two copper tubings 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.
5) Attach the two refrigerant lines to the male couplings on the remote condensing 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.
