L Series® (LG, LC, LH) Rooftop Units
Designed to achieve a low total cost of ownership.
Features and Benefits
Efficient Operation
- Standard
and high efficiencies available in 3- to 30-tons, up to 13.25 SEER, up to 12.2 EER and up to 14.7 IPLV.
- ASHRAE 90.1 compliant.
- ENERGY STAR® qualified.*
Application
solutions for efficient operation
- Integrated
Modular Controller – provides centralized control and fast, simple troubleshooting to reduce operation and service cost.
- Humiditrol® Dehumidification System – helps control humidity levels, improving comfort and indoor air quality.
- Multiple Compressors – allow the unit to provide efficient cooling with four-cooling-stage
capability.
- Thermostatic Expansion
Valves – provide peak cooling performance across the entire application range for better comfort.
- Variable-Frequency Drives – provides variable air volume
unit operation to meet a variety of zoning system needs.
Quick, easy installation and maintenance
- Independent Motor Mount – allows for easy, efficient access without removing top panel.
- Full-Perimeter Base Rail –
provides greater structural integrity so the unit is easier to handle when rigging and transporting.
- Slab Coil – permits faster, more thorough coil cleaning.
- Hinged Toolless Access Panels –
provide quick access to components and protect panels and roof from damage during service.
- Isolated Compressor Compartment – allows performance check
during normal compressor operation without disrupting airflow.
- Slide-Out Blower Deck – improves access for belt, blower and motor, reducing maintenance time.
Reliable performance
- Corrosion-Resistant Cabinet – G-90
galvanized steel cabinet under a two-layer painted surface protects against rust and corrosion.
- High- and Low-Pressure Switches – safeguard compressor from
extreme operating conditions and unnecessary wear and tear.
