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
R75 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.
. Use the pump PURGE button to reduce the water level

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:
. Run the hose to a drain

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.

5.1 Technical Description
The Phoenix R75 uses a refrigeration system similar to
an air conditioner’s to remove heat and moisture from
incoming air and to add heat to the air that is discharged.
Hot, high pressure refrigerant gas is routed from the
compressor to the condenser coil. The refrigerant is cooled
and condensed by giving up its heat to the air that is about
to be discharged from the unit. The refrigerant liquid then
passes through a filter/drier and capillary tubing which

Hot, high pressure refrigerant gas is routed from the
compressor to the condenser coil. The refrigerant is cooled
and condensed by giving up its heat to the air that is about
to be discharged from the unit. The refrigerant liquid then
passes through a filter/drier and capillary tubing which
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.
