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 heat pump is designed and approved for outdoor use qualified persons and do not supersede any national or local only. codes in any way. The installation must comply with all state and local codes as well as the National Electrical Code. The heat pump 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) Models W2GH3 48632A008

Line Set Isolation Installing Vertical Runs (new construction shown) This shows how to install line sets on vertical runs. The following illustrations demonstrate procedures which ensure proper refrigerant line set isolation. NOTE: Similar installation practices should be used if line set is to be installed on exterior of outside wall. Installing Horizontal Runs This shows how to install line sets on horizontal runs. IMPORTANT: Refrigerant lines must not contact structure. NOTES: To hang line set from joist or rafter, use either metal strapping A B C C material or anchored heavy nylon wire ties.

Insulate the suction line with refrigerant line insulation material of " (6.4 mm) or more wall thickness. 1. Route the suction and liquid lines from the fittings on the indoor coil to the fittings on the heat pump. Run the lines in 13. Pack insulating material around refrigerant lines where they as direct a path as possible, avoiding unnecessary turns and penetrate the structure to protect the lines and to minimize bends. vibration transmission. 2. For product efficiency, be sure that the suction line is insulated over the entire exposed length and that both suction and liquid lines are not in direct contact with floors, walls, ductwork, floor joists, or other piping.
