3 Nomenclature actory-installed Options Stainless-Steel Heat Exchanger (Gas units only): A tubular heat exchanger made of 09-type stainless steel is installed in the unit. Low-Ambient Kit: Allows for cooling operation at lower outdoor temperatures. On the - to -ton units, cooling operation is extended from 0 ambient temperature to outside air temperature. On 7½ -0 ton units, cooling operation is extended from ambient temperature to 0 outside air temperature. or ton units, cooling operation is extended from ambient temperature to 0 outside air temperature. Economizers (Downflow): Based on air conditions, can provide outside air to cool the space. Electric Heat Kits (A and heat pump units only): Available in all voltage options. Non-powered onvenience Outlet: A 0V, A, GI outlet makes it easier for technicians to service the unit once an electrician runs power to the outlet. Powered onvenience Outlet: A 0V, A, GI outlet powered with a transformer built into the unit. When a factory-installed powered convenience outlet is installed in the equipment, the unit MA (Min. ircuit Ampacity) will increase by 7.A/.A for 0/0V units, increase by.a for 0V units, and by.a for 7V units. The MOP (Max. Overcurrent Protection) device must be sized accordingly. Disconnect Switch (non-fused; -phase units only): A disconnect switch is installed in the unit and factory wiring will be complete from the switch to the unit. Please note that for air conditioning (DS units) and heat pump models (DSH units), the appropriate electric heat kit must be ordered to be factory-installed along with the disconnect switch (non-fused) when it is ordered. Please note that for models with a powered convenience outlet option and a disconnect switch (non-fused) option, the power to the powered convenience outlet will be shut off when the disconnect switch (non-fused) is in the off position. Return Air and/or Supply Air Smoke Detectors: Return air and/or supply air smoke detectors are installed in the unit. Hinged Access Panels: Allows access to unit s major components. ombined with latches for easy access to control box, compressor, filters and blower motor. Available on all units. Phase Monitor: Phase monitor ( phase only), available for - ton DS, D and DT series models. Phase monitor shall provide protection for motors and compressors against problems caused by phase loss, phase reversal and phase unbalance. Phase monitor is equipped with an LED that provides an ON or AULT indicator. DD ontroller: DD communicating controller, available for - ton DS, D and DT series models with on-board BAnet communication interface. High static belt drive assembly, factory installed. SS-DG7

25 Roof urb Installation Rigging Provisions for forks have been included in the unit base frame. No other fork locations are approved. Unit must be lifted by the four lifting holes located at the base frame corners. Lifting cables should be attached to the unit with shackles. The distance between the crane hook and the top of the unit must not be less than 0. Two spreader bars must span over the unit to prevent damage to the cabinet by the lift cables. Spreader bars must be of sufficient length so that cables do not come in contact with the unit during transport. Remove wood struts mounted beneath unit base frame before setting unit on roof curb. These struts are intended to protect unit base frame from fork lift damage. To remove the struts, extract the sheet metal retainers and pull the struts through the base of the unit. Refer to rigging label on the unit. Important: If using bottom discharge with roof curb, duct-work should be attached to the curb prior to installing the unit.
