IMPORTANT: DO NOT operate the unit without the filter or with a less effective filter as the heat exchanger and coils inside the unit could become clogged and require disassembly to clean.

4.2 Storage

There are two issues to consider when the Phoenix R175 is stored between uses and both pertain to the water trapped in the unit: damage caused by freezing or biological growth. The effect of the trapped water can be greatly reduced if precautions are taken to remove as much as possible before storage.

1.Use the pump PURGE button to reduce the water level in the reservoir

2.Walk out the hose to drain it completely

In order to reduce biological growth flush the unit with a biofungicide that is approved for use with copper, aluminum, polyethylene and ABS. To flush:

1.Run the hose to a drain

2.Plug in the unit but do not turn it on

3.Remove the air filter. Slowly pour a pint of the chemical through the top so that it drains into the heat exchanger

4.Use PURGE button to remove chemicals in reservoir. Run PURGE until hose runs dry

5.Walk out hose to drain completely

6.Replace air filter

cause the refrigerant pressure and temperature to drop. It next enters the evaporator coil where it absorbs heat from the incoming air and evaporates.

The evaporator operates in a flooded condition, which means that all the evaporator tubes contain liquid refrigerant during normal operation. A flooded evaporator should maintain constant pressure and temperature across the entire coil, from inlet to outlet.

The mixture of gas and liquid refrigerant enter the accumulator after leaving the evaporator coil. The accumulator prevents any liquid refrigerant from reaching the compressor. The compressor evacuates the cool refrigerant gas from the accumulator and compresses it to a high pressure and temperature to repeat the process.

5 Service

WARNING: Servicing the Phoenix R175 with its high pressure refrigerant system and high voltage circuitry presents a health hazard which could result in death, serious bodily injury, and/or property damage. Only qualified service people should service this unit.

CAUTION: Do not operate unit without the front housing in place.

5.2 Troubleshooting

No dehumidification, neither hour meter display nor compressor run and POWER button does not turn ON.

1.Unit unplugged or no power to outlet

2.Defective control board

3.Loose connection in internal wiring

No dehumidification, neither hour meter display nor compressor run with POWER button ON.

1.Defective control board

2.Loose connection in internal wiring

R175 specifications

Therma-Stor Products Group has made significant strides in providing efficient and reliable solutions for indoor air quality and moisture control with their R175 model. The R175 is engineered specifically for tackling humidity challenges in various environments, making it a preferred choice for both residential and commercial applications.

One of the standout features of the R175 is its impressive dehumidification capacity. With the ability to remove up to 175 pints of moisture from the air per day, it is well-suited for larger spaces or environments that experience higher humidity levels. This high capacity makes it ideal for basements, large living areas, or commercial spaces that require stringent humidity control.

The R175 operates using advanced desiccant technology. Unlike traditional refrigerant-based dehumidifiers, the desiccant system efficiently absorbs moisture from the air even at lower temperatures, making it functional in settings with cooler conditions without sacrificing performance. This technology is particularly beneficial in areas where temperature fluctuations are common, ensuring consistent moisture control.

Another notable characteristic of the R175 is its energy efficiency. The product is designed to consume minimal energy while maximizing moisture extraction, aligning with modern environmental standards and reducing overall operating costs. Its eco-friendly design reduces the carbon footprint, making it a responsible choice for environmentally-conscious consumers.

Quiet operation is another significant advantage of the R175. The unit is engineered with sound-dampening technologies that minimize noise output, making it appropriate for use in settings where a peaceful environment is essential, such as bedrooms, libraries, or offices.

Ease of use is an essential aspect of the R175. The product features a user-friendly interface that allows users to set and monitor humidity levels effortlessly. Furthermore, it is designed for hassle-free maintenance, with easy access to filters and components, ensuring optimal performance over the long term.

Durability is also key to the R175's appeal. Constructed with high-quality materials, this unit is built to withstand the rigors of daily use in various environments, promising excellent longevity and reliability.

In summary, the Therma-Stor Products Group R175 stands out for its high dehumidification capacity, energy efficiency, quiet operation, user-friendly features, and durability. It presents a robust solution for anyone looking to effectively manage moisture and enhance indoor air quality, making it an excellent investment for maintaining comfortable and healthy spaces.
