altitude. Must be used with propane conversion kit.

 

MIZER- Outdoor and return air dampers that are inter- locked and positioned by a fully-modulating, spring return damper actuator. The maximum leakage rate for the outdoor air intake dampers shall not exceed 2% when dampers are fully closed and operating against a pressure differential of 0.5 IWG. A unit-mounted potenti- ometer shall be provided to adjust the outdoor and return air damper assembly to take in CFM of outdoor air to meet the minimum ventilation requirement of the condi- tioned space during normal operation. During econo- mizer operation, a mixed-air temperature control shall modulate the outdoor and return air damper assembly to prevent the supply air temperature from dropping below 55°F. Changeover from compressor to economizer oper- ation shall be provided by an integral electronic enthalpy control that feeds input into the basic module. The out- door intake opening shall be covered with a rain hood that matches the exterior of the unit. Water eliminator/fil- ters shall be provided. Simultaneous economizer/com- pressor operation is also possible. Dampers shall fully close on power loss.

MOTORIZED OUTDOOR AIR DAMPERS - Outdoor air dampers are positioned by a 2-position,spring-return damper actuator. The maximum leakage rate for the out- door air intake dampers shall not exceed 2% when dampers are fully closed and operating against a pres- sure differential of 0.5 IWG. A unit-mounted potentiome- ter shall be provided to adjust the outdoor damper assembly to take in the design CFM of outdoor air to meet the ventilation requirements of the conditioned space during normal operation. Whenever the indoor fan motor is energized, the dampers open up to one of two pre-selected positions - regardless of the outdoor air enthalpy. Dampers return to the fully closed position when the indoor fan motor is de-energized. Dampers shall fully close on power loss.

OTHER PRE-ENGINEERED ACCESSORIES AVAILABLE

York DM 072 warranty Manual Outdoor AIR Damper

DM 072 specifications

The York DM 072 is a high-performance packaged air conditioning unit designed for commercial and industrial applications. Engineered for efficiency and reliability, the DM 072 is part of York's broader initiative to provide advanced climate control solutions that meet the demands of modern buildings.

One of the standout features of the York DM 072 is its advanced energy efficiency. It employs the latest in variable speed technology, which allows the unit to adjust its output according to the cooling load. This capability significantly reduces energy consumption, leading to lower operational costs, and it aligns with global efforts to promote sustainable energy use.

In terms of design, the York DM 072 is built with a robust aluminum cabinet that provides excellent corrosion resistance. This is essential for units installed in harsh environments, ensuring a long lifespan and reduced maintenance needs. The compact design also allows for easy installation in tight spaces, making it a versatile choice for various building configurations.

The unit is equipped with a high-efficiency scroll compressor, which enhances its cooling capabilities while minimizing noise levels. This is particularly beneficial for commercial office buildings where noise reduction can contribute to a more comfortable working environment. Additionally, the DM 072 features a sophisticated refrigerant management system that optimizes the refrigeration cycle, ensuring consistent performance and maximizing system efficiency.

Another notable aspect of the York DM 072 is its advanced control system. With smart connectivity options, users can monitor and control the unit remotely. This feature not only improves convenience but also aids in proactive maintenance by providing real-time performance data, helping facility managers to identify and rectify issues before they escalate.

The DM 072 also incorporates an effective filtration system designed to improve indoor air quality. With multi-stage filtration, it captures dust, allergens, and other particulates, promoting a healthier environment for occupants.

With a combination of efficiency, durability, advanced technology, and environmental considerations, the York DM 072 stands out as a leading choice in the commercial HVAC market. Whether for new constructions or retrofitting existing systems, it offers reliable performance and environmental stewardship, making it a top contender among packaged air conditioning units.
