I Installation Instructions Split System Condensers Installation/ Startup Information These instructions must be read and understood completely before attempting installation. CAUTION 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 C1-1999 or current edition and Canadian Electrical Code Part 1 CSA C.22.1.
| Split System Condensers Installation Instructions J 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 1. Remove the liquid line fitting and replace restrictor ori- fice. (STANDARD RIGHT compo- nents. APPROVED MATCHED SYSTEM COMPONENTS MUST BE USED. Refer to the Sales Specification Sheet or Split System Summary for match data and orifice HAND THREAD) 2. Make sure the restrictor is installed with the rounded end toward the feeder tubes. See Figure 3.
I Installation Instructions Do not let refrigerant lines come in direct contact with foundation. When running refrigerant lines through the foundation or wall, the openings should be made large enough to allow for a sound absorbing material to be placed or installed between the tubing and the foundation. This will prevent noise transmission between the tubing and the wall section (foundation) or the building.
| Split System Condensers Recommended System Installation Instructions Method Of Evacuating A 1. Connect the vacuum pump to the suction and liquid line gauge ports. 2. If the evacuation is being performed on a new system installation, the valves should be kept in the "front seated” (closed) position. This will allow the mechanic to evacuate the refrigeration lines and the indoor coil, without disturbing the factory charge in the outdoor unit. 3. Follow the vacuum pump manufacturer’s instructions.
Installation Instructions Split System Condensers See Figures 5 thru 8 and Wiring Diagram on unit. Use of Rigid Metal Conduit AIC Condenser Typical Low Voltage Connections It is recommended that wires be tied together or twisted together inside the conduit. This will minimize any buzzing type sounds that could be produced with high current loads, such as during starting. Under some conditions it may be necessary to use a hard start kit to eliminate problem noises.

I Installation Instructions Split System Condensers 2. Measure and record the suction line refrigeration pressure. (Measure at the suction line service valve gauge port.) Using Temperature / Pressure Chart convert this pressure to the saturation refrigerant temperature. The difference between actual and saturated temperatures is the amount of superheat.
| Split System Condensers To Check System Refrigerant Charge (Heating Mode) The recommended method of addition or removal of charge in the heating mode is by weight. The system operation may be checked against the performance charts. Remember, indoor airflow must be approximately 400 CFM per ton to compare operation to performance charts. Defrost System (Heat Pump Only) Time / Temperature Type: The defrost system is electronic with an adjustable time interval of 90, 60, or 30 minutes.
I Installation Instructions Split System Condensers Temperature Adjustment (Demand Defrost) 3. Turn off all power to the Heat Pump. Remove control box cover and locate the electronic defrost control board. The defrost control board has a jumper clip that fits over two pins. To change the temperature termination, remove the jumper clip and place it on pins for the desired interval of 50, 60, 70 or 90 degrees.
| Split System Condensers SHIPPING Installation Instructions J BRACKET A shipping bracket has been added to some chassis to increase the stacking height proved warehousing. for im- If present the bracket may be left in place or removed by the installer. NOTE: The bracket is installed using the same screw(s) that secure the service valve. If only one screw is used there is a clearance hole that fits over one screw securing the suction valve. If bracket is removed. MAKE SURE SCREW(S) IS REINSTALLED.
