Flexibility, serviceability and ease of installation make Landmark rooftop units the ideal choice for virtually any commercial application.

Landmark rooftop units are designed and engineered for installation flexibility, reliable and efficient performance and easy serviceability. Landmark units are available in both standard- and high-efficiency models. And now, with the addition of the optional MSAV® supply fan and Humiditrol® dehumidification technology, the Landmark lineup is more customizable than ever before.

FLEXIBLE OPTIONS

B E N E F I T S Y S T E M S

Environ™ coil system uses up to 52% less refrigerant, is up to 59% lighter and has up to 20% fewer brazed joints than typical units.

High-pressure switch improves reliability by safeguarding the compressor from extreme operating conditions.

Scroll compressor is standard on all units for reliable, long-term operation.

Slide-out blower reduces time needed to adjust fan speed and belt tensioning or for blower cleaning.

Predefined supply-fan motor/drive combinations make selecting components to meet static and airflow requirements quick and easy.

Easy-access gas compartment allows access to all gas components.

Corrosion-resistant, removable drain pan provides application flexibility, durability and improved serviceability. Bottom drain capability is also standard.

Independent Fan Motor Mount allows for easy and efficient service access without removing the top panel.

Isolated compressor compartment allows performance check during normal compressor operation without disrupting airflow.

Fork slots on three sides make it easy to pick up and transport units.

Full-perimeter base rail (with rigging holes) provides greater structural integrity, so the unit is easier to handle when rigging and transporting.

*All CAV units meet DOE 2018 minimum efficiency requirements

The Landmark® lineup gives you the flexibility to choose exactly the right configuration for your application.

• Configuration choices allow you to choose from gas-electric, electric-electric, heat pump, and dual fuel heat pump configurations—in just the right size and at exactly the right price. Standard-efficiency units are available in 2 to 25 tons, and high-efficiency models have capacities ranging from 2 to 20 tons.* More than 100 field-installed options are also available, allowing installers to quickly configure units to perfectly fit the application.

• Optional MSAV® supply fan technology easily adapts to changing conditions, delivering year-round savings and optimal comfort. Quiet, efficient and with an advanced variable-frequency drive, the MSAV supply fan also enhances system performance, delivering power savings of up to 61%.

• Humiditrol® dehumidification technology is now offered as an option on Landmark rooftop units. This simple humidity- control system delivers an efficient and effective way to remove moisture from the air, making it easy to create a healthier and more comfortable indoor environment.

Humiditrol features and benefits.

• Easy to use, integrated dehumidification system that controls humidity, independent of temperature.

• Effectively reduces the spread of allergens, such as mold, mildew and dust mites.

• Significantly improves indoor air quality (IAQ) and comfort.

SIMPLE SERVICEEASY INSTALLATION

Landmark units come with a range of convenient features that make installation fast and easy.

• Insulated base seals the unit to the roof curb without the need for a curb gasket.

• Single hookup gas connection eliminates the need for routing the gas line inside the unit.

• Terminal strip comes standard for easy control connections.

The Simple Service™ System provides easy access to different parts of the unit, reducing service time and aiding problem analysis.

• Accessible gas compartment provides quick and convenient access to all gas components.

• Removeable drain pan simplifies maintenance, while improving application flexibility and serviceability.

• Slide-out blower motor reduces installation time and is easy to service.

• Isolated compressor allows performance check while unit is working, without interrupting airflow.

• Low-maintenance blower belt auto-tensioner aids longer belt life and quick belt replacement.
