Filter Information

The ﬁlter in your Friedrich removes dust, pollen and other impurities from the air as they are drawn through the unit. The ﬁlter is permanent and reusable, and has a germicidal treatment which is not affected by washing.

A clogged, dirty ﬁlter reduces the air ﬂow through the unit and reduces its efﬁciency. You should check the ﬁlter every seven to ten days, depending on the amount your unit is used. Clean the ﬁlter regularly.

FILTER RETAINER CLIPS

The ﬁ lter can be removed for cleaning by opening the front of

the unit and releasing the ﬁ lter from its retaining clips.

Maintenance Checklist

Won’t Cool

If the unit operates, but doesn’t cool, check to see that the con- trols are properly set. Inspect the ﬁlter and clean it thoroughly, if needed. Check to see if the chassis seal gasket is installed (refer to installation instructions).

coil should ice over while cooling, set the thermostat to the warm- est position until the ice on the coil is gone. Setting the thermostat to a slightly warmer position will probably keep ice from forming on the coil. A dirty ﬁlter will contribute to icing.

Won’t Run

If the unit does not operate at all, check that the power supply connections are tight. Check for blown fuses or tripped circuit breakers. Replace blown fuses with the proper size time-delay fuse. The nameplate on the unit shows the proper fuse size. After restoring power, wait three minutes before restarting the unit.

Inside Coil Freezes Up

Your Friedrich Hazardgard is designed not to freeze with outdoor temperatures as low as 45°F (7°C). Freezing should only occur when the outside air is damp and below 45°F (7°C). If the indoor

Cleaning

The front grille of your Friedrich, as well as the complete cabi- net may be cleaned with warm water and a mild detergent. The coils and base pan should be cleaned periodically for the most efﬁcient operation. We suggest you call your Friedrich dealer for this service.

Lubrication

Fan motors are factory lubricated and sealed. No lubrication is required.

SH20, SH15 specifications

The Friedrich SH15 and SH20 models are exemplary representatives of advanced heating solutions, designed to address the diverse needs in residential and commercial environments. Engineered with a focus on efficiency, performance, and user-friendliness, these heating systems make a strong case for modern heating technology.

One of the standout features of both the SH15 and SH20 is their energy efficiency. These models utilize state-of-the-art heat pump technology, which allows them to extract heat from the environment even in colder temperatures. This results in significantly lower energy consumption compared to traditional heating systems, leading to reduced utility bills and a lower carbon footprint. The SH15 is designed for smaller spaces, while the SH20 offers a bit more power, making it suitable for larger areas or homes with greater heating demands.

Both models incorporate advanced inverter technology, which adjusts the compressor speed depending on the heating requirements. This ensures that the units operate at optimal efficiency, providing consistent temperature control while minimizing energy waste. Inverter-driven systems contribute to quieter operation as well, which is ideal for residential settings where noise can be a concern.

User-friendliness is another hallmark of the Friedrich SH15 and SH20. Equipped with intuitive digital controls, users can easily set their preferred temperatures and schedules, allowing for personalized comfort. Moreover, both models support smart home integration, enabling remote access and control through mobile applications. This feature not only enhances convenience but also allows users to monitor energy usage and make adjustments on the fly.

Durability is a key characteristic of these heating systems. Constructed with high-quality materials, the SH15 and SH20 are designed to withstand harsh environmental conditions, ensuring long-lasting performance. They also feature advanced air filtration systems that improve indoor air quality by effectively removing allergens and other pollutants.

In summary, the Friedrich SH15 and SH20 embody the cutting-edge of heating technology, offering powerful, efficient, and user-friendly solutions for diverse heating needs. With their advanced features, smart technology integration, and robust construction, these models are well-suited for modern living, ensuring comfortable and environmentally responsible heating year-round.
