SAFETY CONSIDERATIONS

YORK Model DHG units are single package high efficiency gas-fired central heating furnaces with cooling unit designed for outdoor installation on a rooftop or a slab.

The units are completely assembled on rigid, permanently attached base rails. All piping, refrigerant charge, and electri- cal wiring is factory installed and tested. The units require electric power, gas connection, duct connections, installation of combustion air inlet hood, flue gas outlet hoods and fixed outdoor air intake damper (units without economizer or motorized damper option only) at the point of installation.

The gas-fired heaters have aluminized-steel tubular heat exchangers and spark ignition with proven pilot.

.

FOR YOUR SAFETY IF YOU SMELL GAS:

a.Open windows.

b.Don’t touch electrical switches; do not use any phones in the area of the gas leak.

c.Extinguish any open flame.

d.Immediately call your gas supplier from another location. Follow your gas supplier’s instructions.

e.If you cannot reach your gas supplier, call the fire departments.

Installer should pay particular attention to the words: NOTE, CAUTION, and WARNING. Notes are intended to clarify or make the installation easier. Cautions are given to prevent equipment damage. Warnings are given to alert installer that personal injury and/or equipment damage may result if instal- lation procedure is not handled properly.

Due to system pressure, moving parts and electrical compo- nents, installation and servicing of air conditioning equipment can be hazardous. Only qualified, trained, service personnel should install, repair, maintain or service this equipment.

Observe all precautions in the literature, on labels and tags accompanying the equipment whenever working on air condi- tioning equipment. Be sure to follow all other safety precau- tions that apply.

Wear safety glasses and work gloves, and follow all safety codes. Use a quenching cloth and have a fire extinguisher available for all brazing operations.

This product must be installed in strict compliance with the enclosed installation instructions and any applicable local, state, and national codes includ- ing, but not limited to, building, electrical and mechanical codes.

DHG180, DHG240 specifications

Energy Tech Laboratories has made significant strides in the realm of energy efficiency and renewable technologies with the introduction of their innovative models, the DHG240 and DHG180. These advanced devices are designed to optimize energy consumption, minimize environmental impact, and enhance overall energy management.

The DHG240 model stands out with its high-capacity performance, delivering a robust output of 240 kW. This unit is ideal for large facilities and industrial applications, where energy demands are high. One of its main features is its advanced algorithm for energy distribution, which allows for optimal load balancing across various operational units. This ensures that energy is used efficiently, reducing waste and lowering operational costs.

Similarly, the DHG180 is designed for medium-sized operations, providing an output of 180 kW. It offers an effective solution for businesses seeking to improve energy efficiency without the excessive overhead costs typically associated with larger systems. The DHG180 incorporates state-of-the-art monitoring systems that provide real-time data on energy consumption, allowing operators to make informed decisions and adjust settings as needed.

Both models integrate cutting-edge technologies such as smart grid capabilities and renewable energy sources. They are equipped to handle integration with solar panels and wind turbines, enabling facilities to harness clean energy and reduce reliance on fossil fuels. This feature not only contributes to sustainability goals but also provides a buffer against fluctuating energy prices.

The design of both the DHG240 and DHG180 prioritizes durability and reliability. They are constructed from high-quality materials that withstand harsh operational conditions, ensuring a long lifespan and reduced maintenance costs. Furthermore, these systems are compliant with various energy efficiency standards, making them a responsible choice for environmentally conscious businesses.

User-friendliness is another hallmark of these devices. An intuitive interface allows operators to easily monitor and control energy usage, while remote access compatibility enables management from off-site locations. This flexibility is crucial in today’s fast-paced business environment.

In conclusion, Energy Tech Laboratories’ DHG240 and DHG180 models represent the forefront of energy technology. By delivering high performance, integrating renewable solutions, and prioritizing ease of use, these units empower businesses to achieve their energy efficiency goals while promoting sustainability. Whether for large industries or medium-sized enterprises, these systems are engineered to meet the dynamic needs of modern energy management.
