» Condenser hail guards are factory installed as a standard.
Compressor High performance, low noise scroll compressors with stage control to match the required total load for efficient part load control.
» Resiliently factory-mounted on rubber grommets for vibration isolation.
» Refrigeration circuit includes both a low- and high-pressure transducer, high pressure safety switch and temperature sensors for the suction and discharge lines.
» Unit is factory charged with environmental friendly and sustainable R-410A refrigerant.
» Dual single-stage scroll compressors. » Compressor location outside the condenser section to avoid air bypass.
» Internal overload protection included with compressor. » Crankcase heaters and external thermal overload protection are also provided for compressor durability.
Supply Fan Indoor fan motors are belt-drive as standard to provide easy in the field belt and pulley adjustment for airflow control.
» Slide out forward curb fan for easy maintenance and replacement.
» High-static drive options for applications with high airflow/ static requirements.
» Each fan assembly is dynamically trim balanced at the factory before shipment for quick start-up and efficient operation.
» Motor with thermal overload and phase failure protection is provided for long lasting operation.
Coils All units use large face area outdoor coils. These coils are constructed with seamless copper tubes, mechanically bonded into aluminum plate-type fins with full drawn collars to completely cover the tubes for high operating efficiencies.
The indoor coil section is installed in a draw through configuration to provide better dehumidification.
» Coils are factory pressure tested to ensure pressure and leak integrity.
» Coils include a Thermal Expansion Valve per circuit, high- and low pressure switches, service ports and high capacity filter drier.
» Aluminum micro-channel indoor coil on 25-ton units

Applications & Serviceability
8 www.daikinac.com SS-DBC15
ApplicationsDaikin Rooftop units are intended for comfort cooling applications in normal heating, ventilating, and air conditioning. Consult your local Daikin sales representative for applications involving operations at high ambient temperatures, high altitudes, non-cataloged voltages, or for job-specific unit selections that fall outside of the range of the catalog tables.
For proper operation, units should be rigged in accordance with instructions stated on the installation manual. Fire dampers, if required, must be installed in the ductwork according to local and/or state codes. No space is allowed for these dampers in the unit.
Follow factory check, test and start procedures explicitly to achieve satisfactory start-up and operation.
Most rooftop applications take advantage of the significant energy savings provided with economizer operation. When an economizer system is used, mechanical refrigeration is typically not required below an ambient temperature of 50°F on most cases.
Serviceability Daikin packaged rooftop units are built with serviceability in mind, designed to make future maintenance and service on the unit easy and accessible.
» Our packaged rooftop units offer a slide out blower to facilitate the access and removal of the fan.
» Independent compressor outside of the air bypass to eliminate component blockage and provide easy access.
» Color coded and continuously marked wire to identify point-to-point component connections.
» Condenser clean out from inside-out. » Easy access to control panel.

Service ClearanceAllow for recommended service clearances as shown in the image below. In situations that have multiple units, a 36" minimum clearance is required between the condenser coils. A clearance of 48" is recommended on all sides of the unit to allow service access and to ensure proper ventilation and condenser airflow. The top of the unit should be unobstructed. Provide a roof walkway along the sides of the unit for service and access to controls and components. Contact your Daikin sales representative for service requirements less than those recommended.

Installation
Unit LocationThe structural engineer must verify that the roof has adequate support and ability to minimize deflection. Take extreme caution when using on a wooden roof structure. Unit condenser coils should be in a location that avoids any heated exhaust air.
Allow sufficient space around the unit for maintenance/service clearance. Consult your Daikin sales representative if available clearances do not meet minimum recommendations.
Where code considerations, such as the NEC, require extended clearances, these take precedence.
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 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 forklift 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. 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. For further and more detailed information please refer to our Daikin Light Commercial Packaged unit IOD.
Roof Curb InstallationThe roof curb is field-assembled and must be installed level (within 1/16" per foot side to side). A sub-base must be constructed by the contractor in applications involving pitched roofs. Gaskets are furnished and must be installed between the unit and curb. For proper installation, follow NRCA guidelines. In applications requiring post and rail installation, an I-beam securely mounted on multiple posts should support the unit on each side. In addition, the insulation on the underside of the unit should be protected from the elements. Applications in geographic areas subjected to seismic or hurricane conditions must meet code requirements for fastening the unit to the curb and the curb to the building structure.
