1 SINGLE-PACKAGED HEAT PUMP 50 HZ UNITS 7 TO 18 KW (2 TO 5 NOMINAL TONS) Product Data UNIT (50 Hz) Single-packaged Heat Pump for Residential and Light Commercial applications. Features/Benefits One-piece heat pump with optional electric heater, low installation cost, dependable performance and easy maintenance. Efficient operation Energy-efficient design with EERs (Energy Efficiency Ratios) of up to 9.2 Easy Installation Factory-assembled package is a compact, fully self-contained, heat pump unit that is pre-wired, pre-piped, and pre-charged for minimum installation expense. units are available in a variety of standard capacity ranges. Units install easily on a rooftop or at ground-level. Durable, dependable components Compressors are designed for high efficiency. Each compressor is hermetically sealed against contamination to help promote longer life and dependable operation. Vibration isolation provides quiet operation. Compressors have internal high-pressure and overcurrent protection. Convertible duct configuration Unit is designed for easy use in either downflow or horizontal applications. Each unit is easily converted from horizontal to downflow, and includes horizontal duct covers. Direct-drive multi-speed, blower motor is standard on all models. Direct-drive, condenser-fan motors are designed to help reduce energy consumption and provide for cooling operation down to 55 F/12.7 C outdoor temperature.

2 Corporate thermostats work with Carrier s small packaged products as a system to promote year round comfort. Refrigerant system is designed to provide dependability. Liquid refrigerant strainers are used to promote clean, unrestricted operation. Each unit leaves the factory with a full refrigerant charge. Refrigerant service connections make checking operating pressures easier. Indoor and outdoor coils are computer-designed for optimum heat transfer and cooling efficiency. The indoor coil is fabricated from copper tube and aluminum fins and is located inside the unit for protection against damage. The outdoor coil is internally mounted on the top tier of the unit. A FIOP (Factory-Installed Option) metal louvered grille is available for all models. Copper fin coils and pre-coated fin coils are available from the factory by special order. These coils are recommended in applications where aluminum fins are likely to deteriorate due to corrosion. They are ideal for seacoast applications. Low sound ratings ensure a quiet indoor and outdoor environment with sound ratings as low as 77 dba. (See page 3.) Easy to service cabinets provide easy single-panel accessibility to serviceable components during maintenance and installation. The base with it s integrated drain provides easy ground level installation with or without a mounting pad. (Convenient rigging holds are provided to manipulate the unit on the job site.) A nesting feature ensures a positive base to roof curb seal when the unit is roof mounted. A convenient 3/4-in./19.05mm-wide perimeter flange makes frame mounting on a rooftop easy. Downflow operation is easily provided in the field to allow vertical ductwork connections. The base utilizes knockout style seals on the bottom openings to ensure a positive seal in the horizontal airflow mode. Cabinets are constructed of heavyduty, phosphated, zinc-coated, prepainted steel capable of withstanding 500 hours of salt spray. Interior surfaces are insulated with cleanable semi-rigid insulation board, which keeps the conditioned air from being affected by the outdoor ambient temperature and provides improved indoor air quality. (Conforms to American Society of Heating, Refrigeration and Air Conditioning Engineers No. 62P.) The sloped drain minimizes standing water. Standard metal duct covers with insulation come with the unit and cover the duct openings. These can be left in place if the units are applied to downshot. Short-Cycling protection for the compressor is incorporated into our defrost control board ensuring a five minute delay (+/-2 minutes) before restarting compressor after shutdown for any reason. Pressure Switches provide high and low pressure safety protection and protect the unit from operating in unsuitable conditions.

At 21 C (70 F) Return Indoor Air and 6.7 C (20 F) air entering outdoor coil, the integrated Heated capacity is 4.8 kw (16,390 Btuh). Use Integrated heating capacity value since deductions for outdoor coil frost and defrosting have already been made (No correction is required). The required heating capacity is 7.4 kw (25,250 Btuh). Therefore, 2.6 kw (8,860 Btuh) figured 7.4 kw minus 4.8 kw (25,250-16,390 Btuh) additional electric heat is required.
