Use wire of an appropriate gage and outdoor rating. 4) Install line and neutral wires from the fan motor leads in the icemaker fan motor junction box to the leads in the remote condenser unit junction box. Use wire of an appropriate gage and outdoor rating. 5) Replace the junction box covers and the louver panel in their correct positions. 7.
H. Connection to an R-404A Parallel Rack System WARNING • Installation must be performed by properly trained and EPA-certified service personnel. • Failure to install the appliance within these guidelines may adversely affect safety, performance, component life, and warranty coverage. NOTICE The icemaker, line set, and rack system must contain the same type of refrigerant. Mixing of refrigerants will result in improper operation and possible damage to the refrigeration system. 1.
5) Use an electronic leak detector or soap bubbles to check for leaks. Add a trace of refrigerant to the line set copper tubes (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 the line set copper tubes 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.
