Puron is an HFC refrigerant which does not contain chlorine that can harm the ozone layer. Puron refrigerant is in service in millions of systems, proving highly reliable, environmentally sound performance.Easy Installation Factory-assembled package is a compact, fully self-contained, electric cooling unit that is prewired, pre-piped, and pre-charged for minimum installation expense. These units are available in a variety of standard cooling sizes with voltage options to meet residential and light commercial requirements. Units are lightweight and install easily on a rooftop or at ground level.

The high tech composite base eliminates rust problems associated with ground level applications.Innovative Unit Base DesignOn the inside a high-tech composite material will not rust and incorporates a sloped drain pan which improves drainage and helps inhibit mold, algae and bacterial growth. On the outside metal baserails provide added stability as well as easier handling and rigging.Convertible duct configurationUnit is designed for use in either downflow or horizontal applications. Each unit is converted from horizontal to downflow and includes horizontal duct covers. Downflow operation is provided in the field to allow vertical ductwork connections. The basepan seals on the bottom openings to ensure a positive seal in the vertical airflow mode.Efficient operation High-efficiency design offers SEER (Seasonal Energy Efficiency Ratios) of up to 13.5.Durable, dependable components Scroll Compressors are designed for high efficiency. Each compressor is hermetically sealed against contamination to help promote longer life and dependable operation.

Each compressor also has vibration isolation to provide quieter operation. All compressors have internal high pressure and overcurrent protection.ECM Motor is standard on all 50ES-A models.Direct-drive PSC (Permanent Split Capacitor) condenser-fan motors are designed to help reduce energy consumption and provide for cooing operation down to 40ºF (4.4ºC) outdoor temperature. Motormaster® II low ambient kit is available as a field-installed accessory.Thermostatic Expansion Valve - A hard shutoff, balance port TXV maintains a constant superheat at the evaporator exit (cooling cycle) resulting in higher overall system efficiency.Refrigerant system is designed to provide dependability. Liquid filter driers 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.High and Low Pressure Switches provide added reliability for the compressor.Indoor and Outdoor coils are computer-designed for optimum heat transfer and 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.Low sound ratings ensure a quiet indoor and outdoor environment with sound ratings as low as 75dBA.Easy to service cabinets provide easy 3-panel accessibility to serviceable components during maintenance and installation. The basepan with integrated drain pan provides easy ground level installation with a mounting pad. how to disconnect ac unitA nesting feature ensures a positive basepan to roof curb seal when the unit is roof mounted. wall air conditioning units best buyA convenient 3/4-in.

Standard horizontal metal duct covers with insulation come with the unit and cover the horizontal duct openings. These can be left in place if the units are converted to downflow.Cabinets are constructed of heavyduty, phosphated, zinc-coated prepainted steel capable of with standing 500 hours in salt spray. Interior surfaces of the evaporator/heat exchanger compartment 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 pan minimizes standing water in the drain. An external drain is provided.

Dehumidification FeatureThis unit has independent fan speeds for low stage cooling and high stage cooling. In addition, 208/230 VAC models have thefield-selectable capability to run an enhanced dehumidification (’DHUM’) speed on high stage cooling (as low as 320CFM perton). Coupled with the improved dehumidification associated with low stage cooling, the DHUM speed allows for a complete dehumidification solution independent of cooling stage. The dehumidification control must open the control circuit on humidity rise above the dehumidification set point.NOTE: The enhanced dehumidification feature on high stage cooling does not support use of an economizer.Cabinets are constructed of heavyduty, phosphated, zinc-coated prepainted steel capable of withstanding 500 hours in salt spray. Interior surfaces of the evaporator/electric heater compartment are insulated with foil-faced insulation, which keeps the conditioned air from being affected by the outdoor ambient temperature and provides improved indoor air quality.
