It is the owner's and installer's responsibility to read and comply with all safety information and instructions accompanying these symbols. Failure to heed safety information increases the risk of personal injury, property damage, and/or product damage. Recognize this symbol as a safety precaution. WARNING WARNING GoodmHaIGnH V6OLTAGE!

In more severe weather locations, it is consideration is given to the weather-tight integrity of the roof. recommended that the unit be elevated to allow unobstructed Since the unit can vibrate during operation, sound vibration drainage and airflow. transmission should be considered when installing the unit. Vibration absorbing pads or springs can be installed between the The following elevation minimums are recommended: unit legs or frame and the roof mounting assembly to reduce noise vibration.

REFRIGERANT LINES CAUTION Mounting the evaporator coil above the heat pump will require an inverted loop in the suction line adjacent or near the connection The compressor POEGooiol dfomr aRn-41160A units is extremely to the evaporator coil. The top of the loop must be slightly higher susceptible to moisture absorption and could cause than the top of the evaporator coil. compressor failure. Do not leave system open to atmosphere any longer than necessary for installation.

Install one oil trap at the evaporator for When running refrigerant lines through a foundation or wall, a height difference of more than 15 ft (4.5 m) between indoor and openings should allow for sound and vibration absorbing material outdoor units. to be placed or installed between tubing and foundation. Any gap between the foundation or wall and refrigerant lines should be A filled with a pliable silicon-based caulk, RTV or a vibration damping material. Avoid suspending refrigerant tubing from joists and studs with rigid wire or straps that would come in contact with the tubing. Use an insulated or suspension-type hanger. Keep both lines separate and always insulate the suction line. These sizes are recommended for line lengths of 79 ft (24 m) or less to obtain optimum performance. For alternate line sizing options or runs of more than 79 ft (24 m), refer to Remote Cooling Service Manual, TP-107 Long Line Set Application R- 410A or contact your distributor for assistance.
