Rheem Commercial High-Efficiency Condensing Unit
Standard Features

• New composite base pan - dampens sound, captures louver panels, eliminates corrosion and reduces number of fasteners needed
• Powder coat paint system - for a long lasting professional finish
• Scroll compressor - uses 70% fewer moving parts for higher efficiency and increased reliability
• Modern cabinet aesthetics - increased curb appeal with visually appealing design
• Curved louver panels - provide ultimate coil protection, enhance cabinet strength, and increased cabinet rigidity
• Optimized fan orifice - optimizes airflow and reduces unit sound
• Rust resistant screws - confirmed through 1500-hour salt spray testing
• PlusOne™ Expanded Valve Space - 3"-4"-5" service valve space - provides a minimum working area of 27-square inches for easier access
• PlusOne™ Triple Service Access - 15" wide, industry leading corner service access - makes repairs easier and faster. The two fastener removable corner allows optimal access to internal unit components. Individual louver panels come out once fastener is removed, for faster coil cleaning and easier cabinet reassembly
• Diagnostic service window with two-fastener opening - provides access to the high and low pressure.
• External gauge port access - allows easy connection of "low-loss" gauge ports
• 35% fewer cabinet fasteners and fastener-free base - allow for faster access to internal components and hassle-free panel removal
• Service trays - hold fasteners or caps during service calls
• QR code – provides technical information on demand for faster service calls
• Fan motor harness with extra long wires allows unit top to be removed without disconnecting fan wire.
• Low ambient control - a pressure sensitive fan cycling control allows operation of units down to 0°F [-18°C].
• High pressure control - manual reset control deactivates system if abnormally high pressure occurs.
• Low pressure control - automatic reset control deactivates system if abnormally low pressure or refrigerant loss occurs.
• Service valves - standard on liquid and suction lines.
• Condenser fan motors - direct drive, single-phase permanently lubricated ECM motors with inherent overload protection.
• Transformer - 50VA step-down type, from Line to 24 Volts.
• Contactor - the contactor is an electrical switch which operates the compressor and condenser fans. Its 24 Volt coil is activated through the High Pressure Control and Low Pressure Control on a call for cooling.
• Equipment ground - lug for field connection of ground wire.
• Testing - all units are run tested at the factory prior to shipment. Units are shipped with a holding charge of nitrogen.
• Compressor time delay control - compressor will remain off for five minutes after power or thermostat interruption, allowing system pressures to equalize. (Model No. RXMD-B01)
• Filter/Drier - a liquid line filter drier is shipped with each unit for field installation.

Rheem Commercial Air Handler
Cabinet - Powder coat painted. Matching discharge plenums and decorative supply and return air grilles are available for use when units are to be installed within conditioned space.
Motor- Inherently protected motors are mounted inside of insulated cabinet to reduce motor noise. A choice of motor horsepowers and drive combinations are available to allow you to meet specified CFM at various static pressures up to 2" [.498 kPa] external static pressure.
Low Profile - Allows for horizontal installation in most standard drop ceiling applications, and the movement of units through most standard doorways for addition or replacement work.
Thermal Expansion Valves - Standard all models.
Filters - One inch [25 mm] throwaway filters are standard, but filter racks are designed to accept either one inch [25 mm] or two inch [51 mm] filters.
Evaporator Coil -Two circuit, interlaced row split coils are constructed with copper tubes and aluminum fins mechanically bonded to the tubes for maximum heat transfer capabilities. All coil assemblies are leak tested up to 450 PSIG [3100 kPa] internal pressure prior to installation into units.
Refrigerant Connections - Field piping connections are made through a fixed post between two side access panels on either side of the unit. Allows flexibility to meet most field conditions as well as full accessibility after the installation is complete.
Units may be used with two straight cool condensing units or single circuit manifolded in the field using the copper fittings shipped with each unit. The RHGL Air Handler has not been tested, rated or certified to operate with dual remote heat pumps.
Drain Pan -The galvanized steel drain pan is designed to trap condensate in either vertical or horizontal installations. Condensate drain connections are located on both sides of the unit allowing complete flexibility to meet most field conditions.
Service Access -Two removable panels on top and each side of the unit are easily removed for access to motors, blowers, sheaves, and filters.
Horizontal or Vertical - All models are designed for either application and can be installed in either position as supplied from the factory.
Testing - All units are run tested at the factory prior to shipment.
Units are shipped with a holding charge of nitrogen.
