Nomenclature
Factory-Installed Options• Stainless-Steel Heat Exchanger (Gas units only): A tubular heat exchanger made of 409-type stainless steel is installed in the unit.• Low-Ambient Kit: Allows for cooling operation at lower outdoor temperatures. On the 3- to 6-ton units, cooling operation is extended
from 60°F ambient temperature to 35°F outside air temperature. On 7½ -20 ton units, cooling operation is extended from 35°F ambient temperature to 0°F outside air temperature. For 25 ton units, cooling operation is extended from 24°F ambient temperature to 0°F outside air temperature.
• Economizers (Downflow): Based on air conditions, can provide outside air to cool the space.• Electric Heat Kits (AC and heat pump units only): Available in all voltage options.• Non-powered Convenience Outlet: A 120V, 15A, GFCI outlet makes it easier for technicians to service the unit once an electrician runs
power to the outlet.• Powered Convenience Outlet: A 120V, 15A, GFCI outlet powered with a transformer built into the unit. When a factory-installed powered
convenience outlet is installed in the equipment, the unit MCA (Min. Circuit Ampacity) will increase by 7.2A/6.5A for 208/230V units, increase by 3.3A for 460V units, and by 2.6A for 575V units. The MOP (Max. Overcurrent Protection) device must be sized accordingly.
• Disconnect Switch (non-fused; 3-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 (DSC 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. Combined with latches for easy access to control box, compressor,
filters and blower motor. Available on all units.• Two-speed indoor fan blower models are standard on 6, 7½, 8½, 10, 12½, 15, 20 & 25 ton units. Section 6.4.3.10.b of ASHRAE Standard
90.1-2010 and Section 6.5.3.2.1.a of ASHRAE Standard 90.1-2013 require a minimum of two fan speeds. Section 140.4(m)1 of California Energy Commission Title 24 2013 contains a similar provision. When the units with the two-speed indoor fan blowers operate on a call for the first stage of cooling, the fan operates at low speed, which is 66% of full speed. When the units operate on a call for the second stage of cooling, the fan operates at full speed. In heating operation, the fan operates at full speed. During ventilation operation, the fan operates at low speed.
• Phase Monitor: Phase monitor (3 phase only), available for 3 - 25 ton DS, DC 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 FAULT indicator.
• DDC Controller: DDC communicating controller, available for 3 - 25 ton DS, DC and DT series models with on-board BACnet® communication interface.
¹ Wire size should be determined in accordance with National Electrical Codes. Extensive wire runs will require larger wire sizes.² May use fuses or HACR-type circuit breakers of the same size as noted.Note: Always check the S&R plate for electrical data on the unit being installed.

Maintain an adequate clearance around the unit for safety, service, maintenance, and proper unit operation. Leave a total clearance of 75” on the main control panel side of the unit for possible removal of fan shaft, coil, electric heat, and gas furnace. Leave a clearance of 48” on all other sides of the unit for possible compressor removal or service access, and to ensure proper ventilation and condenser airflow. Do not install the unit beneath any obstruction. Install the unit away from all building exhausts to inhibit Ingestion of exhaust air into the unit’s fresh-air intake.

Roof Curb 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 60".• Two spreader bars must span over the unit to prevent dam-
age 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. Duct-work dimensions are shown in Roof Curb Installation Instructions Manual.Refer to the Roof Curb Installation Instructions for proper curb installation. Curbing must be installed in compliance with the National Roofing Contractors Association Manual.Lower unit carefully onto roof mounting curb. While rigging the unit, the center of gravity will cause the condenser end to be lower than the supply air end.Bring condenser end of unit into alignment with the curb. With condenser end of the unit resting on curb member and using curb as a fulcrum, lower opposite end of the unit until entire unit is seated on the curb. When a rectangular cantilever curb is used, take care to center the unit. Check for proper alignment and orientation of supply and return openings with duct. To assist in determining rigging requirements, unit weights are shown below.
Note: These weights are calculated without installed accessories.

Roof Curb Installation
Curb installations must comply with local codes and should follow the established guidelines of the National Roofing Contractors Association.Proper unit installation requires that the roof curb be firmly and permanently attached to the roof structure. Check for adequate fastening method prior to setting the unit on the curb.Full perimeter roof curbs are available from the factory and are shipped unassembled. The installing contractor is responsible for field assembly, squaring, leveling, and mounting on the roof structure. All required hardware necessary for the assembly of the sheet metal curb is included in the curb accessory package.
• Determine sufficient structural support before locating and mounting the curb and package unit.• Duct-work must be constructed using industry guidelines. The duct-work must be placed into the roof curb before mount-
ing the package unit. Our full perimeter curbs include duct connection frames to be assembled with the curb. Cantile-vered-type curbs are not available from the factory.
• Contractor furnishes curb insulation, cant strips, flashing, and general roofing material.• Support curbs on parallel sides with roof members. To prevent damage to the unit, the roof members cannot penetrate
supply and return duct openings.Note: The unit and curb accessories are designed to allow vertical duct installation before unit placement. Duct installation after unit placement is not recommended.See the manual shipped with the roof curb for assembly and installation instructions.
