Phoenix Dry Max
Part No. 4036000
Patent Pending
The Phoenix Dry Max is 6% smaller than the closest
dehumidier and yet it still has an integrated handle and
wheels as well as onboard storage for the power cord and
condensate hose! The all-new Phoenix Micro-Channel
condenser allows us to pack so much performance into such a
small dehumidier.
The feedback on the stacking of the AirMax was so positive we
made sure to build it into the Phoenix Dry Max.
We’ve also added a new four line display which provides you
with all the information you need to take readings directly from
the home screen.
A new Status Bar is located at the top of the new control panel
to give you instant feedback about the dehumidier from
across the room.
Remove only four fasteners and you have easy access to
service the unit.

3.4 Condensate Removal
The Phoenix Dry Max is equipped with an internal
condensate pump to remove the water that is condensed
during dehumidication. This allows the condensate to
be pumped up to 20 feet with the attached hose. If the
condensate must be pumped more than 20 feet above the
unit, a second pump must be added to relay the condensate.
The condensate pump automatically purges when the
reservoir is full. Use the PURGE button to manually remove
condensation.
3.5 Ducting
A wire duct collar is supplied to allow 10” lay-at duct to
be attached to the Phoenix Dry Max outlet. Lay-at plastic
ducting is available; see section 6 Options and Accessories.
To attach ducting to the wire duct collar, put the plastic duct
end through the collar center and roll the duct end outward
so that it overlaps the outside of the collar. The duct and
collar may then be quickly attached to the Phoenix Dry Max
by snapping the collar over the four exhaust tabs.
3.6 Defrost Cycle
If the low side refrigerant temperature drops due to excessive
frost formation on the evaporator coil and below the
temperature set point, the thermistor activates the PLC and
Status Light Indicator. The compressor is cycled off and on by
the thermistor temperature measurement. The air mover will
continue to run, causing air to ow through the evaporator
coil and melt the ice when the compressor is off. When the
air temperature and/or humidity increases, the evaporator
temperature will rise and the thermistor will end the defrost
cycle at the temperature set point
3.7 POWER Button
When the dehumidier is plugged in it will enter stand-by
mode.
Press the button to turn the dehumidier on. The unit
will begin the Powering Up sequence and you will see this

4 Maintenance
4.1 Air Filter
The Phoenix Dry Max is equipped with a pleated media air
lter that must be checked regularly. The standard lter
is a MERV-10 high efciency lter. Operating the unit with
a dirty lter will reduce the dehumidier’s capacity and
efciency and may cause the compressor to cycle off and on
unnecessarily. The lter can generally be vacuumed clean
several times before needing replacement. Replacement
lters can be ordered from the manufacturer or purchased
locally if available IMPORTANT: DO NOT operate the unit
without the lter or with a less effective lter as the
coils inside the unit could become clogged and require
disassembly to clean.
4.2 Storage
There are two issues to consider when the Phoenix Dry Max
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 ush the
unit with a bio-fungicide that is approved for use with copper,
aluminum, polyethylene and ABS. To ush:
1. Run the hose to a drain
2. Plug in the unit but do not turn it on
3. Remove the air lter. 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 lter
5 Service
WARNING: Servicing the Phoenix Dry Max 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 top cover in
place.
CAUTION: Do not operate unit without the top cover in
place.
5.1 Technical Description
The Phoenix Dry Max uses a refrigeration system similar
to an air conditioner’s to remove 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 lter/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 ooded condition, which means that all the
evaporator tubes contain liquid refrigerant during normal
operation. A ooded evaporator should maintain constant
pressure and temperature across the entire coil, from inlet
to outlet. The mixture of gas and liquid refrigerant enter the
compressor after leaving the evaporator coil. The compressor
evacuates the cool refrigerant gas from the accumulator and
compresses it to a high pressure and temperature to repeat
the process.
5.2 Troubleshooting
No dehumidication, control does not light up and unit will
not turn on from power button.
1. Unit unplugged or no power to outlet
2. Defective control board
3. Loose connection in internal wiring
