Design Features


ApplicationPackaged curb-mounted vertical discharge or horizontal discharge and return water-to-air heat pump air condi-tioners are an excellent choice for a multitude of building applications ranging in unit sizes from 12.5 to 35 tons. Versatile for new building construction or retrofit projects from offices, schools, health care and retirement facili-ties to restaurants, hotels, motels, and industrial opera-tions. The RWA and RWC models are normally used with a water loop system utilizing a cooling tower and boiler, this unit is designed to operate with entering water temperatures between 55°F and 95°F. The RGA and RGC models are rated for ground loop heat exchanger application with entering fluid temperature between 30°F and 100°F.These outdoor roof mounted units are positioned on the roof curb, above the conditioned space, for minimal field ductwork. Roof curbs are available as a field-installed accessory. After assembly each unit is charged and run tested in both the heating and cooling cycles for reliable operation. Units are certified and conform to UL/ANSI Standards by ETL.

Model RWA Unit

Standard Design FeaturesHeavy Duty CabinetAll models are constructed of G-90 galvanized steel. Gasketed access doors are 20-gauge steel with 1", 4-pound density closed cell insulation and a 24-gauge galvanized steel liner. Standard outer panels are insu-lated with 1" 4-pound density closed cell foam insulation with a 24-gauge galvanized steel interior liner. Service access doors are mounted with stainless steel hinges and equipped with one-quarter turn cam operated adjustable compression type latches. The underside of the base panel is insulated with 3/8" closed cell foam insulation.

Paint FinishThe unit is constructed of hot dipped galvanized G-90 steel that is chemically treated with zinc phosphate, coated with 0.2 to 0.3 MIL polyurethane primer then finished with 0.7 to 0.8 MIL polyester top coating.

CompressorUnits equipped with scroll compressors selected for their reliability and high efficiency. Compressor mountings are designed to reduce vibration transmission to the unit structure and minimize piping stress.

Compressor ProtectionAll compressors have crankcase heaters and internal overheat protection.

Separate Refrigeration CircuitsMultiple refrigeration circuits are standard. Multi com-pressor models provide the added benefit of partial standby. Also, they provide two-stage operation with one compressor being activated from the first stage of the two-stage space thermostat on the cooling cycle. On the heating cycle, all compressors are activated by the first stage of the space thermostat.

Indoor Air CoilThe indoor air coils have aluminum fins formed on multiple rows of seamless copper tubing arranged in a staggered tube configuration. The tubes are mechani-cally expanded, firmly bonding the tube to the collar of each fin.

The Coaxial Water CoilThe Coaxial Water Coil consists of an enhanced surface inner copper tube with outer steel tube (tube-in-tube). Water connections are stubbed off inside the cabinet. Field piped return and supply water lines enter through individual sleeves in the compressor base pan section after passing through the roof curb. Units are shipped with water pressure taps and upper elbows for easy con-nection to the water source. RGA and RGC models are equipped with fully insulated refrigerant and water lines and an insulated coaxial water coil.

Air and Water Proving SwitchesAn air proving switch prevents system operation unless there is proof of blower operation. The water proving switch prevents system operation if there is no fluid flow through the coaxial heat exchanger.

Design Features

Evaporator Blower and MotorAll units are fitted with a DWDI forward curved fan as-sembly mounted on spring vibration isolation. A slide out deck allows for blower assembly removal from the cabinet to service or inspect. The shaft is belt driven with adjustable drive sheave connected to an open drip proof motor with sealed ball bearings. Adjustable V-belt drives provide a minimum rating of 140% of the motor name-plate brake horsepower when the adjustable pulley is at the minimum RPM. The bearings on both the blower shaft and motor are permanently lubricated.

Evaporator Access

Refrigeration CircuitThe refrigerant system(s) operate with R-410A refrig-erant and include the compressor, crankcase heater, copper-tube, aluminum finned condenser and evapora-tor coils. The refrigerant circuit includes filter/drier, high pressure safety control (manual-reset), low pressure control/loss of charge protector (auto-reset), dual gauge connections for high and low pressure readings and thermal expansion valve with adjustable superheat. The condensing section of the unit is integral to the unit.

Electromechanical ControlsUnit electrical power entry is through the curb. The starter/control panel includes a programmable logic con-troller and a complete modular, integrated motor control system mounted on din rails. All safety and operating controls shall be factory mounted. The system includes all relays, fan contactors, compressor contactors, and power distribution. The 24-volt control circuit includes a transformer and low voltage terminal strip for interface with a control system.

Terminal Board ConnectionsTerminal boards are furnished for 24-volt thermostat con-nections on units.

FiltersAll models are shipped with 2-inch thick disposable glass fiber media filters mounted in a factory installed flat filter rack on the return air opening. The standard filter rack is capable of using 2" filters, 4" filters or 2" pre-filters and 4" after filters.

Sloped Stainless Steel IAQ Condensate Drain PanThe condensate drain pan is double-sloped to comply with ASHRAE Standard 62-1089R and fabricated from stainless steel. The bottom is insulated with closed cell neoprene insulation. Condensation may be drained from a MPT drain fitting positioned at the exterior of the cabinet.

Power EntryA chase is installed in the curb, directly under the electri-calcontrol section to bring power wiring inside the curb, preventing a separate roof penetration. The sleeve must be sealed after wiring is completed with suitable mastic to prevent water from entering the space. Power enter-ing through the curb is standard in all models.

Multiple Refrigeration CircuitAll units use two separate refrigeration circuits. This de-sign offers two stages of cooling for load shedding when conditions allow.Multiple compressors on independent circuits also offer the added benefit of continuous operation in the event of a failure in one of the circuits.

ElectricalClogged Filter Indicator (Filter Differential Gauge)Dirty or clogged filters are indicated when the preset pressure differential across the filters is reached. The indicator is factory installed and is manually reset. It includes contacts for remote indication.

FirestatThis control, mounted in the return air section, de-ener-gizes the unit when return air reaches 135°F. The firestat is a manual reset control.

115-Volt Ground Fault Circuit Interrupter (GFCI ReceptacleA 115-volt GFCI receptacle mounted in a 2" x 4" en-closure and is furnished with a 15 amp circuit breaker. Separate 115-volt power source and ground is required.

Humidity ControlHot Gas BypassHot gas bypass is a means of capacity control during lower ambient temperature conditions. The Hot Gas Bypass valve is an adjustable valve and should be set to open when the refrigerant suction pressure drops to 107-112 psig. It varies unit capacity by introducing discharge refrigerant into the evaporator circuit where it creates a false evaporator load. The hot gas is cooled prior to its return to the compressor as it passes through the evaporator.The Hot Gas Bypass Solenoid Valve is energized through the thermostat and routs discharge gas to the hot gas bypass valve. It is de-energized during the pump down cycle.

Hot Gas Reheat with Water Regulating Valve (WRV)Hot gas reheat (HGRH) helps to maintain specific hu-midity and temperature levels in a conditioned space by cooling, dehumidifying and then re-heating the air. The modulating HGRH provides superior temperature control compared to typical "on-off" HGRH.HGRH includes a water regulating valve to maintain head pressure by adjusting water flow.Hot gas reheat requires use of a conventional field sup-plied humidistat.

Installation and ApplicationDaikin WRWA/WRWC units are designed for rooftop or slab mounted installations.

Unit Location - General • Avoid locations next to exhaust fans or flues. • Select a location where external water drainage

cannot collect around the unit. • Locate the unit as near as possible to the center

of the area to be environmentally controlled. • Other considerations such as unit supports, roof

opening, roof curb flashing, drain requirements, and power supply locations should be checked and verified.

Unit Location - Rooftop • Structural members supporting the unit must be

sufficiently strong for the weight of the unit and mounting rails.

Transmission of sound into the building is sometimes a problem when the structure is not strong enough. • Units with vertical returns are available with a 14"

high solid bottom roof curb. Units with horizontal supply and return air duct connections are made with the use of a 24" high solid bottom roof curb. Rooftop curbs are sold separately as an option.

• Proper installation for the RTU requires that the roof curb be firmly and permanently attached to the roof structure. Check for adequate fastening method prior to setting rooftop unit on curb.

• Inspect roof curb to insure that none of the utility services (electric, gas, drain lines) routed through the curb protrude above the curb.

• Duct connections should be made before unit is set on roof curb.

• Being a fully welded solid bottom curb, duct openings are to be sized and cut by the installing contractor.

• Tie down kits are required when the units are mounted on roof curbs and will be included with every unit. See installation instructions included with the tie down kit.

• Rooftop units also require the installation of an equipment support rail in addition to the roof curb.

Installation and Application


Unit Location - Slab • When installed at ground level, the unit should be

mounted on a level concrete slab which should extend at least 2" beyond the unit on all sides.

• The top of the slab should be 2" above the ground level. Where snowfall is anticipated, mount the unit above the maximum snow depth for the area.

• The depth of the slab below the ground level and its structural design is governed by the type of soil and climatic conditions.

• The slab must not be in contact with any part of the building wall or foundation. The space between the slab and building wall prevents the possibility of transmitting vibration to the building.

• The dimensions of the slab or roof mount should be checked and verified before the equipment arrives.

• Locate the unit so roof runoff water does not pour directly on the unit. Provide gutter or other shielding at roof level.

• Do not locate the unit under an overhang that will short circuit hot air to the coil intakes.

ClearancesA clearance of 24"- 36" must be allowed for service and maintenance access to the compressor and electrical panelSufficient clearance must be available for service, edge of roof, other units, or hazards.Adequate clearance around the unit must be kept for safety, accessibility, service and maintenance. 48 inches clearance is required on the control end of the unit. This clearance must also be maintained for compressor removal.A 48 inch clearance is also required on the (outside air) end of the unit for blower removal and for adequate out-side air accessibility. All combustible materials must be kept out of the area.Figure 1: Unit Clearance Area

DuctworkProperly sized and installed ductwork is critical to reli-able performance of the unit and system. All ductwork must be installed according to local codes, practices and requirements.All duct connections with the use of a curb are to be field sized and cut. Industry manuals should be used as a guide to size and design the duct system.Ducts passing through unconditioned spaces must be well insulated and include a vapor barrier to prevent condensation from forming.

Condensate PipingA condensate trap must be installed. Trap must be primed before operating unit. Units with high internal and external static pressure drops will require a deeper trap.If condensate is to be piped into the building drainage system, the drain line must penetrate the roof external to the unit. Refer to local codes for additional requirements.Drainage of condensate directly onto the roof is ac-ceptable if permitted by local codes. A small drip pad of either stone, tar, wood or metal should be provided to prevent any possible damage to the roof.

ElectricalWiring ConnectionsPower wiring should be connected to the main power terminal block located within the main control section.Power wiring connections on units with factory discon-nects should be made at the line side of the disconnect switch.Low voltage wiring connections are made to the remote mounted controller or time clock.

Independent Power SourceIt is recommended that an independent 115-volt power source be brought to the vicinity of the rooftop unit for portable lights and tools used by the service mechanic.

Main Power WiringThe units are factory wired for the voltage shown on the nameplate. Make sure main power wiring is sized for the minimum wire ampacity shown on the nameplate.An external weather-tight disconnect switch properly sized for the unit total load is required for each unit. Dis-connect must be installed in accordance with local and/or national electric codes.Power wiring may enter the unit through the base pan and roof curbs on all models. Install conduit connectors at the entrance locations. External connectors must be weatherproof.
