Engineered Features

MEA # (Heating): 73-03-E

MEA # (Cooling): 179-03-E

Multi-Capacity Two-Stage:

Simple thermostatic control seamlessly stages the compressor and indoor airflow rate between high and low capacity operations without cycling the compressor. This helps to maximize comfort, humidity control, energy efficiency and overall reduction in compressor cycling for improved system life.

Step Capacity Compressor:

Copeland step-capacity (2-stage) scroll compressors are designed for increased efficiency, quieter operation and improved reliability for longer life.

R-410A Refrigerant:

Designed with R-410A (HFC) non-ozone depleting refrigerant in compliance with the Montreal protocol and 2010 EPA requirements.

Thermal Expansion Valves:

All models use TXV.

Phase Rotation Monitor:

Standard on all 3 phase scroll compressors. Protects against reverse rotation if power supply is not properly connected.

Twin Blowers:

Move air quietly. All models feature variable speed blower motors providing automatic airflow adjustment for high static or free blow (non-ducted) operation at a very low sound level. Motor overload protection is standard on all models.

ECM Indoor Blower Motor:

Features a variable speed motor providing super-high efficiency, low sound levels and soft-start capabilities. The motor is self-adjusting to provide the proper airflow rate for the staged capacity, and for higher static pressure in ducted installations without user adjustment or wiring changes.

Integrated DSI Control:

Direct spark ignition control and remote sensor delivers smooth, proven ignition sequence.

Timed blower control and diagnostics are also features of integrated control.

Gas Controls:

Honeywell gas valve and burner orifices are factory standard for natural gas. Field convertible to LP gas with certified conversion kit.

Hinged Service Door:

Hinged door with compression latches (one lockable) for filter service access, heat exchanger inspection, and indoor blower/ motor service.

Pre-Painted 20 Gauge Zinc Coated Steel Cabinet:

Cleaned, rinsed, sealed and dried before the polyurethane

Liquid Line Filter Drier:

Protects system against moisture.

Aluminum Finned Copper Coils:

Grooved tubing and enhanced louvered fin for maximum heat transfer and energy efficiency.

High & Low Pressure Switches are Auto-Reset

Built-in lockout circuit resets from the room thermostat. Provides commercial quality protection to the compressor.

Compressor Control Module:

Standard on all units. Built-in off-delay timer adjustable from 30 seconds to 5 minutes. 2-minute on-delay if power interrupt. 120-second bypass for low pressure control, and both soft and manual lockouts for high and low pressure controls. Alarm output for alarm relay.

Crankcase Heaters:

Factory installed crankcase heaters are standard on all models. This helps to insure ease of start at low temperatures and improves compressor life.

Ventilation Controller:

Automatically adjusts damper position to maintain the desired ventilation airflow rate up to 480 cfm of fresh air during any operation mode. Fully closes during unoccupied modes. Factory set for 480 cfm. Also, CO2 sensor ready - just add CO2 sensor for demand ventilation based on CO2 level in the space.

Electrical Components:

Are easily accessible for routine inspection and maintenance through a right side, service panel opening. Features a lockable, hinged access cover to the circuit breaker or rotary disconnect switch.

PTCR Start Assist:

Standard on 1-phase models.

Heat Exchanger:

Heavy duty 18-gauge stainless steel tubular heat exchanger. Mechanically joined construction. Ten-year warranty.

In-Shot Burners:

Advanced burner design, quiet operation. Low NOx models available. Low NOx models can be converted to LP gas. High altitude kits available.

primer is applied. The cabinet is handsomely finished with a baked on textured enamel, which allows it to withstand 1000 hours of salt spray tests per ASTM B117-03.

16 Gauge Zinc Coated Unit Base

Two-Inch, Pleated Disposable Air Filters:

Are standard equipment.

Condenser Fan and Motor

Shroud Assembly:

Slides out for easy access.

Circuit Breakers/Rotary Disconnect:

Standard on all versions of single (230/208 volt) and three phase (230/208 volt) equipment. Rotary disconnects are standard on all versions of three phase (460 volt) equipment.

Slope Top:

Standard feature for water run-off.

Full Length Mounting Brackets:

Built into cabinet for improved appearance and easy installation.

Top Rain Flashing:

Standard feature on all models.

Ventilation Options:

Several patented ventilation options are available and can be factory or field installed.
