PA5Z Self-Contained Single Packaged Air Conditioner

This unit is a packaged air conditioner for manufactured housing, residential, and light commercial applications. The unit design is the result of our firm commitment to the development of the finest air conditioners that modern technology can offer.
The unit is built in one basic cabinet size and features a round or rectangular side-by-side duct configuration.
R-454B is the latest choice of refrigerant to help meet the 2025 GWP requirement. This unit is designed and tested with R-454B and contains a dissipation system.
FACTORY-ASSEMBLED PACKAGE is a compact, fully self-contained, electric cooling unit with horizontal supply and return ducts. The unit is available in a variety of standard cooling sizes to meet residential and light commercial requirements. Unit installs easily on a ground level pad.
EASY TO INSTALL - The unit is small, compact, and easy to handle. Every unit has an identical 32 x 51-in. (813 x 1295 mm) footprint to make planning simple. The concise design uses less sheet metal and makes the unit lighter than other units. The unit can be easily positioned on the job site with the hand holds built into the unit basepan. AERODYNAMIC FAN BLADE DESIGN reduces the overall sound now as low as 70dBA.
SERVICE ACCESS makes installation and maintenance quicker and easier. This unit is designed to be serviced from both the side and front. The design allows easy access for installation and maintenance procedures on the unit. Routine maintenance tasks such as coil cleaning are sped up with the multiple access side panels.
NO-RUST BASEPAN WITH INTEGRATED DRAIN PAN is standard on all units. The unit features a tough, hightech, composite material basepan with integrated drain pan. The composite material eliminates the potential problems of rust and premature replacement which are common with standard metal basepans.
DURABLE PRE-PAINTED STEEL CABINET protects against harsh weather. The watertight construction and corrosion-resistant finish will keep it looking like new for years. The paint treatment process ensures quality protection against the elements. A compact, low-profile design utilizes a louvered coil enclosure for protection against vandalism and hail damage.
INDOOR AIR QUALITY is designed into the unit. A sloped drain pan minimizes the amount of standing water inside the unit, which limits mold and mildew growth. The drain pan is made of a rust-proof material and will not deteriorate or release foreign matter into the airstream.
LIGHTWEIGHT, COMPACT CONSTRUCTION is ideal for manufactured housing and residential applications. This unit is one of the lightest, most compact packaged units ever designed. It’s light weight (244 lb [111 kg] for the 024 size) makes the unit easier to handle. The low height keeps ductwork connections to a minimum and makes units less visible.
This unit utilizes a structural beam design to form the four sides of the cabinet. Only 12 different pieces of sheet metal are used in the unit construction to simplify the unit for greater reliability.
EFFICIENT, DEPENDABLE PERFORMANCE with durable compressors designed for efficiency. The unit offers up to 13.4 SEER2 (Seasonal Energy Efficiency Ratio) cooling performance efficiencies. This performance level can reduce cooling expenses by as much as 30% compared to older cooling equipment.
DURABLE, DEPENDABLE, 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 overcurrent protection.
DIRECT-DRIVE MULTISPEED, BLOWER MOTOR is standard on all models. It’s high efficiency design ensures high performance with most duct systems.
DIRECT-DRIVE, PSC CONDENSER-FAN MOTORS are designed to help reduce energy consumption and provide for cooling operation down to 40°F (4.4°C).
REFRIGERANT SYSTEM is designed to provide dependability. Liquid refrigerant filter driers are used to promote clean, unrestricted operation. Each unit leaves the factory with non-ozone depleting and low global warming potential R-454B refrigerant charge. Refrigerant service connections make checking operating pressures easier. Factory-installed leak detection dissipation system for added safety.
AIR HANDLING LEAKAGE - Cabinet air leakage less than 2.0% at 1.0 in. W.C. and cabinet air leakage less than 1.4% at 0.5 in W.C. when tested in accordance with ASHRAE standard 193
ACCESSORY ELECTRIC HEATERS - A variety of accessory electric heaters are available. These heaters are comprised of a separate heater module mounted on the blower inlet and remote mounted controls located in the unit control box. Single point electrical connections are available for powering both the heater and the unit.
