5. Line Set Installation
Precharged factory line sets, available as optional equipment from Hoshizaki America, are recommended. For details, see "II.G.5.a) Factory Line Set Installation." Field fabricated line sets are allowed. For details, see "II.G.5.b) Field Fabricated Line Set
Installation." a) Factory Line Set Installation
1) Route the factory line set (see "II.G.4 Line Set Size and Refrigerant Charge" for details) 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. 11. Factory fabricated line sets are precharged and do not need to be evacuated. If the line set is too long or too short, see "II.G.5.a)(1) Factory Line Set Modification."
NOTICE
• Ensure that there are no traps and no kinks in the line set. The service loop is not considered an oil trap.
• Do not coil extra line set.
2) Connect the refrigerant lines to the appropriate male fittings on the remote condenser unit first and then at the icemaker. Make a proper connection as follows: a. Remove the protective covers from the male fitting and female coupling.
b. Apply Polyol Ester (POE) refrigerant oil or Parker Super O Lube to the entire male fitting, including O-ring, diaphragm, and threads before making the connection.
See Fig. 12. NOTICE! Do not use thread sealant on the fittings. Use POE refrigerant oil or Parker Super O Lube only. Couplings are one-time use only.
c. Make sure the male fitting and female coupling are properly aligned, then start the connection by hand to ensure that it is not cross threaded. d. Place a backup wrench on the back of the female coupling, then tighten the connection with a wrench until it is tight. At this point, the nut has covered most of the threads on the male fitting. NOTICE! Failure to use a backup wrench may result in damage to the line set and possible refrigerant leaks.
e. Mark a reference line on the female coupling and the remote condenser unit or icemaker panel. Using a backup wrench on the back of the female coupling, tighten the six-sided nut of the female coupling an additional 1/6 turn. See Fig. 13.
NOTICE! Confirm connection is free of leaks.
3) If you lengthened the line set as outlined in "II.G.5.a)(1) Factory Line Set Modification" and it exceeds 66' (20 m), see "II.G.4. Line Set Size and Refrigerant Charge" for proper charging of the appliance.
24
(1) Factory Line Set Modification
1) Recover the line set charge through the Schrader access ports on the Parker quick connect couplings and store it in an approved container. Do not discharge the refrigerant into the atmosphere. Remove the extra line set length or add extra tubing.
When adding extra tubing, insulate the additional copper tubes separately.
2) Use an electronic leak detector or soap bubbles to check for leaks. Add a trace of refrigerant to the lines through the Schrader access ports on the Parker quick connect couplings (if using an electronic leak detector), and then raise the pressure using nitrogen gas (140 PSIG). WARNING! Do not use R-404A as a mixture with pressurized air for leak testing.
3) Evacuate through the Schrader access ports on the Parker quick connect couplings and charge with R-404A refrigerant vapor to a pressure of 15 to 30 PSIG. Go to step 2 in
"II.G.5.a) Factory Line Set Installation." b) Field Fabricated Line Set Installation
1) Route the copper tube liquid line and copper tube discharge line (see "II.G.4 Line
Set Size and Refrigerant Charge" for details) 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. 11.
NOTICE
• Ensure that there are no traps and no kinks in the line set. The service loop is not considered an oil trap.
• Do not coil extra line set. Fabricate the line set to the proper length.
2) Insulate the two copper tubes 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. NOTICE! Before brazing, remove the Schrader valve core from the access port. When brazing, protect the coupling by using a wet cloth to prevent the coupling from overheating. Do not use silver alloy or copper alloy containing arsenic.
4) Allow the coupling to cool, then replace the Schrader valve core.
5) Use an electronic leak detector or soap bubbles to check for leaks. Add a trace of refrigerant to the lines through the Schrader access ports on the Parker quick connect couplings (if using an electronic leak detector), and then raise the pressure using nitrogen gas (140 PSIG). WARNING! Do not use R-404A as a mixture with pressurized air for leak testing.
6) Evacuate through the Schrader access ports on the Parker quick connect couplings and charge with R-404A refrigerant vapor to a pressure of 15 to 30 PSIG.
