Valued Carrier Customer, Carrier’s Architects and Engineer’s manual has been specifically developed to make your product and accessory selection easier and faster. This manual will help you customize your application to ensure the greatest comfort for your guests and the highest reliability and lowest costs for you. Enjoy the ultimate in comfort, humidity control, and energy savings with Carrier’s complete line of Packaged Terminal Air Conditioning (PTAC) products.
APPLICATIONS Whether you are designing a new structure or replacing packaged terminal air conditioning units in an existing building, Carrier will meet your needs.
APPLICATIONS (cont) APPLICATION CONSIDERATIONS Oversizing If a PTAC unit is oversized (cooling capacity is greater than required capacity for the specific application), the unit will cool the space down to the desired temperature too quickly. The unit will cycle on and off, however, dehumidification only takes place when the unit is operating. The result of this type of application in a hot and/or humid climate would be a cool, yet excessively humid, space.
PRODUCT OVERVIEW (52P AND 52C) This section summarizes product features covered in detail in later sections of this manual: 2 AIR FILTERS LOUVERED FRONT PANEL 2-WAY DISCHARGE GRILLE WIRE SCREEN FRESH AIR CONTROL ARM BI-MOLDED CONDENSER SHROUD CONTROL DOOR INDOOR COIL THERMOSTAT WITH TEMPERATURE LIMITER MODE SELECTION SWITCH ACCESS TO ELECTRICAL COMPONENTS THROUGH CONTROL BOX DOOR COPPER TUBE ALUMINUM FIN COILS BASEPAN FOR CONDENSATE REMOVAL ROTARY COMPRESSORS WALL SLEEVE Polymer, Metal or Ext
PRODUCT FEATURES AND BENEFITS (52P AND 52C) The 52P and 52C models are a single-package, through-the-wall unit for heating and cooling hotel rooms, offices, apartments, condominiums, and residential additions.
NO-RUST WEATHER LAST™ WALL SLEEVE AND FRONT PANEL The indoor front panel and polymer wall sleeve use nonmetallic compounds that never rust or corrode, do not support combustion, and do not give off toxic fumes. The weather-resistant feature exceeds requirements of Underwriters’ Laboratories and resists damage caused by impact and scratching. The Weather Last feature also insulates and has up to 10 times the acoustic absorption of metal cabinets.
PRODUCT FEATURES AND BENEFITS (cont) TWO-PIECE LIFETIME INDOOR FILTER New two-piece removable filters easily slide in and out from the front of the PTAC unit and are interchangeable. The front panel does not need to be removed to access or change the filters. The filters are washable and permanent. Two-Piece Indoor Filter WASHABLE VENT AIR FILTER The unique vent system is activated by a two-position control. Fresh outside air is redirected by the vent door to an inside low-pressure area.
POWER CORD FOR 265-V UNITS A power cord is included for 265-v units. The power cord is 18 in. long (cord extends 15 in. from bottom of front panel) and per UL and National Electrical codes must plug into an electrical subbase. 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 265-V Unit with Power Cord BI-MOLDED CONDENSER SHROUD BI-MOLDED CONDENSER SHROUD The bi-molded condenser shroud provides easy access for service and maintenance of the condenser coil and related components.
PRODUCT FEATURES AND BENEFITS (cont) EASY ACCESS TO CHASSIS Access to the chassis simply requires removing four screws and then sliding the chassis out of the sleeve for service. CHASSIS ATTACHMENT SCREWS (SAME LOCATION ON OPPOSITE SIDE) Easy Service Access HIDDEN CONTROLS Fan Cycle Switch The factory-wired control box houses all control components and is quickly accessible without removing the chassis from the wall sleeve.
ENHANCED COPPER TUBING Enhanced copper tubing is more efficient and durable and can be repaired in the field, if required. Because copper is a very stable metal, it is durable and resists corrosion.
PRODUCT FEATURES AND BENEFITS (cont) HEAT PUMPS PAY THEIR OWN WAY How The Heat Pump Works Heat pump models are available at a nominal additional cost. In many locales, the payback is realized in just a few months. Cost and payback details are provided on the next page. Special Features Two-Stage Indoor Thermostat: In Hot Weather: The indoor thermostat senses the indoor temperature and automatically turns on the electric heat to warm the room quickly.
HEAT PUMP ENERGY SAVINGS Heat pumps save more on operating costs during the heating cycle than heat/cool models. The table below shows that the higher initial cost of purchasing a heat pump is quickly made up in lower operating costs. Use the map to identify the climate zone’s designated number. Reading down the left-hand column of the table, select the cost/kWh rate in this zone that most closely approximates your local rate.
