We have provided many important safety messages in this manual and on your appliance. Always read and obey all safety messages. This is the safety alert symbol. This symbol alerts you to potential hazards that can kill or hurt you and others. All safety messages will follow the safety alert symbol and either the word "DANGER" or "WARNING." These words mean: DANGER You can be killed or seriously injured if you don't immediately follow instructions. WARNING You can be killed or seriously injured if you don't follow instructions. All safety messages will tell you what the potential hazard is, tell you how to reduce the chance of injury, and tell you what can happen if the instructions are not followed. INSTALLATION REQUIREMENTS These instructions are intended as a general guide only for use by The condensing unit is designed and approved for outdoor qualified persons and do not supersede any national or local use only. codes in any way. The installation must comply with all state and local codes as well as the National Electrical Code. The condensing unit must be installed with no ductwork in the airstream. The outdoor fan is not designed to operate against any additional static pressure. Whirlpool Gold(R) Model W4GC6 48487D008

Flush Refrigerant Lines Refrigerant lines must be flushed by a licensed, EPA certified Polyol ester (POE) oils are used in Whirlpool units charged refrigerant technician in accordance with established procedures. with R-410A refrigerant. Residual mineral oil from the R-22 system can act as an insulator, inhibiting proper heat transfer. NOTES: It can also clog the thermal expansion valve, reducing system performance and capacity. R-410A outdoor systems are not recommended for use with indoor systems that have used R-22 as the refrigerant. Failure to properly flush the system according to the following However, if this unit is being matched with an approved line instructions will void the warranty. set or indoor coil which was previously charged with R-22 refrigerant, or if it is being matched with a coil which was Tools and Parts manufactured before January 1999, the R-22 coil and line set must be flushed prior to installation. 2 clean R-22 recovery Gauge set for R-22 cylinders refrigerant Check the refrigerant lines for size and length.
