I II General Warnings WARNING Model Identification AR Before servicing or installing this equipment, the electrical power to this unit must be in the “OFF” position. Caution, more than one disconnect may exist. Failure to observe this warning may result in an electrical shock that can cause personnel injury.
IV. Unit Inspection The heating mode temperature rise is dependent upon the system airflow, the supply voltage, and the heat kit size (KW) selected. Use the following table to determine the temperature rise (oF): Upon delivery, the unit is to be inspected for damage. Any damage must be reported immediately to the carrier. Do not install this equipment if it is determined that the integrity or safety has been compromised by freight damage.

Supply Voltage - Heater Kit Models. When a heater kit is used the system uses a single point wiring hook-up. The supply wire is to be routed through conduit from the service disconnect box to the heater kit. The heat kit is equipped with a knockout suitable for ½” or ¾” conduit dependent on the KW.
• • • the CKL120 with the AR120 it is necessary to manifold the suction lines into a single connection. Similarly, the liquid lines of the AR120 are to be manifolded when matched with a single condenser/heat pump. See the following sketch for additional details. The model number agrees with the approved models (see the “Electric Heat” section of this manual). The correct size (kW) Electric characteristics, voltage and phase, agree with the building electrical supply.
