Air-Cooled

Indoor Self-Contained Systems

with PURON

Refrigerant (R-410A)

5 to 20 Nominal Tons

The 50XCA single-package cooling units with integral air-cooled condensers offer:

• Compact, durable, and attractive cabinet fits any working environment

• Available in ducted or free return with rear return connections with vertical supply air discharge

• Provides high-efficiency cooling for commercial and industrial projects

• Rear condenser inlet and discharge and belt drive condenser fan permit condenser air connections to be ducted through window or wall louver

• Uses Puron

refrigerant (R-410A)

Features/Benefits

The Omnizone 50XCA units provide a practical and economical approach to comfort conditioning requirements for offices, factories, and other applications in existing buildings when indoor aircooled condensers are required.

Design flexibility

The 50XCA indoor packaged units are designed to provide the flexibility required in replacement, renovation, and new construction. Units are available in 6 sizes from 5 tons to 20 tons which meet the needs for cooling restaurants, retail stores, warehouses, offices, and building additions.

Features/Benefits (cont)

The compact footprint and service from the front of the units save valuable floor space in equipment rooms. Belt drive condensers provide adequate static to overcome ducting and louver static losses. This allows units to be positioned against an existing window or wall louver, or ducted to the outside, as required. These units can be installed in the equipment room or the conditioned space and used for either ducted or free return applications. Unit supply air discharge is vertical.

Easy installation and maintenance

The units are completely pre-piped and wired at the factory to ensure time and money saving installation and service. Exterior access panels are easily removed to provide speedy inspection, and service work may be done from the front of the unit. Precision engineered parts translate to a quality built, reliable design that will operate efficiently, minimize service calls, and provide years of reliable operation.

Designed for customer satisfaction

Where space and styling are important considerations, 50XCA units are designed to exceed expectations. The high quality baked enamel finish will fit any environment attractively. These packaged systems provide the user with economy and product satisfaction in cooling, dehumidification, filtering, and air circulation.

Efficient design to increase savings

In order to provide an energy efficient HVAC solution, all 50XCA units have been designed to exceed the ASHRAE

90.1 (2010) guidelines.

• Space-saver slab type evaporator and condenser coils use advanced heat transfer technology and provide peak heat transfer efficiency with large coil face area. Fins are mechanically bonded to nonferrous, seamless tubing for efficient leak-free operation.

• Quiet fan performance moves large volumes of indoor air. Compact housing and specially designed discharge air section provide superior air-handling capacity.

• Convenient front access electrical control center contains all factory pre-wired control devices.

• A stainless steel, sloped, condensate pan is standard. As a result of this new design, the coil is easily accessed for cleaning.

• The cabinets are constructed of galvanized steel, bonderized, and coated on all external surfaces with a baked enamel finish. The paint finish is nonchalking and is capable of withstanding ASTM (American Society for Testing and Materials) Standard No. B117 500-hour salt spray test.

• Choose between a full line of roommounted thermostats.

• Full compressor protection is assured by several devices, including current-sensing lockout relay(s), antishort cycle control, and high and low-pressurestats. These devices lock out the compressor(s) under abnormal operating conditions to prevent compressor damage and ensure long life.

Table of contents

• The 50XCA units are covered by a standard limited 5-year warranty on the compressor and a standard limited one-year warranty on all other parts.

• Easy to understand and operate controls provide a virtually mistakeproof control operation.

• All motors are protected against single-phasing conditions.

• Units are built in an ISO 9001:2000 (International Standards Organization) certified manufacturing facility, and are fully run-tested.

Environmentally sound

Carrier’s Puron® refrigerant (R-410A) enables you to make an environmentally responsible decision. Puron refrigerant (R-410A) is an HFC refrigerant that does not contain chlorine that is damaging to the stratospheric ozone layer. Puron refrigerant (R-410A) is unaffected by the Montreal Protocol. Puron refrigerant (R-410A) is a safe, efficient and environmentally sound refrigerant for the future.

Special features for outstanding performance

• High-efficiency scroll compressors deliver quiet, reliable cooling capacity. Compressor motor protection is assured by quick-acting, internal sensing elements that prevent trouble before it starts.

Operating sequence

All units require the addition of a thermostat accessory package to complete the control circuit. The sequence of operation may vary depending on which package is selected.

Room-mounted thermostat — The unit uses an electronic thermostat mounted in the conditioned space.

Fan circulation set to the FAN position, the evaporator-fan motor will operate to provide air circulation.

Cooling when the compressor runs, depending on the setting of the thermostat fan selector switch. When the thermostat closes (on a call for cooling), the control relay condenser-fan contactor and compressor contactor(s) close. The control relay will start the indoor fan if it is not already running. The condenser fan contactor will start the condenser air fan and the compressor contactors will immediately start the compressor(s).

— The evaporator will operate continuously or

— When the thermostat selector switch is

A second stage on 50XCA12 to 24 units will close if additional cooling demand is required, and will start the second-stage compressor. When the thermostat is satisfied, the second-stage compressor will stop first, and then the first-stage compressors will stop when cooling demand is satisfied. The condenser will also stop as soon as both cooling stages are satisfied.

A 5-minute timer, TDR (time-delay relay), will prevent the compressor(s) from restarting for 5 minutes after any compressor has stopped.

All units — The control circuit incorporates a current sensing lockout relay (Cycle-LOC™ device) that locks off the compressor(s) when any safety device is activated (low or high pressure switches, or compressor internal overload). If any compressor safety device opens, the compressor will stop. High and low-pressure switches and compressor motor overload protectors will reset automatically when the condition which caused the device to trip has dropped below the reset condition. To reset the CycleLOC control device, manually turn the control power OFF, then back ON.

Application data

Location

For best results unit must be properly located and installed. Selected location should not be adjacent to an acoustically sensitive space, for example a conference room or executive office. The best location is in mechanical rooms near areas like elevators, restrooms, stairways, or similar spaces. The mechanical room should use construction methods which will help isolate the transmission of acoustical energy.

Since these units typically use large quantities of ducted condenser air, select a location with the best access to an outside window or wall to accommodate condenser air louver. Locate the unit as close to the wall opening as possible but allow space for return air inlet and access to the evaporator and condenser coil for cleaning. Units on the same floor should have a minimum of 6 ft between units to prevent recirculation of condenser air. Units floor to floor should have a minimum of 10 ft between units to prevent recirculation. Units should not be located with several units pulling condenser air from a small space between buildings, where air may be recirculated. Recirculation of condenser air will result in increased head pressure which may cause units to trip on high pressure.

There are several methods for applying 50XCA units in different space applications. See page 33 for recommended equipment room applications and locations of key components.

Moving units into existing buildings

The 50XCA06-14 units are designed to pass through most 36-in. door openings. The filter rack may also be removed.

Unit isolation

Unit compressors are internally isolated and the compressor compartment is lined with acoustical insulation. If additional vibration isolation is desired, rubber in-shear pads are recommended under the four corners of the unit. Spring isolation is not recommended. All duct connections to the unit should be made with flexible connections to prevent any transmission of vibration to the ductwork.

Evaporator ductwork

Supply duct should be properly supported and the aspect ratio as close to square as possible. Duct should be sized for a maximum of 2000 fpm velocity in areas outside the equipment room. The duct should be lined with acoustical insulation for a minimum of 10 ft beyond the equipment room. A flexible duct connection should be used on the connection to the unit to prevent transmission of any unit vibrations into the duct.

Return duct may be attached to the unit, but is not necessary. The return to the unit should prevent line of sight visibility to the space. Insulated return duct is also recommended for acoustically sensitive spaces. Maximum velocity should not exceed 1000 fpm over occupied spaces. Adequate return area is essential for proper operation.

Condenser ductwork

Condenser supply and discharge air ducts should be as short and straight as possible. Cross-sectional area of the inlet and discharge should never be less than the face area

of the unit openings. When bends must be made, they should be as gradual as space limitations will allow. If the unit will be operated in cold outdoor weather, or if dampers are not provided at the louver, then the condenser ducts should be insulated to prevent condensation.

Design of the louver used for the inlet and discharge of the condenser airflow is critical to preventing recirculation of air and high pressure tips. The louver blades must be heavy enough to prevent unit airflow from drawing them together. Louver blades should be a minimum of 18 gage, and widths over 30 in. should have stiffeners. The inlet louver should not have a flange and the discharge louver should have a flange which directs the air away from the inlet. The use of a deflector in conjunction with the condenser air discharge is also recommended.

Piping traps

All 50XCA units have a drain for the condensate from the evaporator coil. The condensate trap should have a depth adequate to allow 2 in. of water in the trap with the unit running. Provide a clean-out on the trap and vent and pitch the trap for proper drainage.

Controls

All units require a room mounted 24-v thermostat to complete the control system. Carrier has several versions of thermostats to meet a wide range of job conditions, including fully programmable and light-activated versions.

Operational limits

Airflow — 300 to 500 cfm per ton Air temperature to evaporator:

Condenser air temperature

Maximum 115 F Minimum without low ambient 55 F Minimum with low ambient 0° F

Sound considerations

All units are acoustically insulated. When installed in or near areas requiring additional sound attenuation:

• Locate unit in equipment room or closet

• Use acoustic lining in ductwork

• Provide square duct elbows with acoustic lining and

turning vanes

• Locate the first supply outlet no less than 10 ft from a

lined elbow.

• If unit is located in the conditioned space, return air

opening from the space should be a lined elbow or equivalent.

• For critical applications, use packaged sound attenua-

tors or duct silencers. Sound attenuation may be used on both evaporator air and condenser air.

Setting condenser fan speed

*Provide access to clean condenser coil. NOTE: Refer to Installation Instructions for detailed louver information.

TYPICAL UNIT LOCATION

a50-8507

The 50XCA condenser has a centrifugal blower and a variable pitch drive which allow adjusting the condenser airflow to match the static from the louvers, ductwork,

filters, and sound traps (if used). It is best to adjust the fan to the nominal airflow and the rpm which will achieve this performance. Excess airflow and rpm will make units noisier.
