I Installation Instructions Split System Condensers Installation / Startup Information These instructions must be read and understood completely before attempting installation. CAUTION VV ARNING Installation or repairs made by unqualified persons can result in hazards to you and others. Installation MUST conform with local building codes or, in the absence of local codes, with the the National Electrical Code NFPA 70/ANSI C1i-1999 or current edition and Canadian Electrical Code Part 1 CSA C.22.1.
| Split System Condensers Installation Instructions § Locating The Outdoor Unit: Check local codes covering zoning, noise, platforms. If practical, avoid locating next to fresh air intakes, vent or bedroom windows. Noise may carry into the openings and disturb people inside. Roof top installations are acceptable providing the roof will support the unit and provisions are made for water drainage and the noise or vibration through the structure.

| Split System Condensers Installation Instructions § Installing Refrigerant Lines Component Matches Check to see that you have the proper system compo- nents. APPROVED MATCHED SYSTEM COMPONENTS MUST BE USED. Refer to the Sales Specification Sheet or Split System Summary for match data and orifice sizes. The outdoor units are shipped with a refrigerant charge to match the indoor unit and 15 ft. (4.5m) of refrigerant line. If shorter or longer lines are used, the charge will have to be adjusted.
I Installation Instructions Split System Condensers Line Valves The outdoor condensing unit is supplied with straight sweat brass service valves with copper stubs. NOTE: Do not use any portion of the charge for purging or leak testing. It is mandatory that a thorough evacuation of the refrigerant in the piping and evaporator be performed. All line valves are positioned to seal the refrigerant in the condensing unit with gauge ports open to connecting lines when the Schraeder valve is depressed.
| Split System Condensers Installation Instructions § Gauge Ports: All Valves REFRIGERATION Check for leaks at the schrader port and tighten valve core if necessary. Install plastic caps finger tight. For extended piping over the recommended 75 feet please refer to Extended Length Refrigerant Piping Manual (Part # 42106111400). Ball Valves PIPING & CHARGING On models with ball type valves use a 6” crescent wrench to rotate the valve stem 90° counter clockwise. Retighten valve cap to 6-8 ft. Ibs.

I Installation Instructions NOTE: Each time that charge is added or removed from the system, allow the system to run approximately 15 minutes before pressure and temperature readings are taken and superheat calculations made. NOTE: Indoor Wet Bulb Temperature ( and Relative Humidity) will alter superheat values. All readings should be at 50% humidity inside and 350 to 450 CFM per ton across the indoor coil.

| Split System Condensers Installation Instructions § Maintenance Condensate Electrical Shock Hazard. Drain During the cooling season check at least monthly for free flow of drainage and clean if necessary. Shut off electric power at fuse box or service panel before making any electrical connections. Cleanliness Failure to shut off electric power can result in, property damage, personal injury and/or death.
