Owner’s Manual — Phoenix D385
Installation, Operation & Service Instructions
Read and Save These Instructions
The Phoenix D385 provides the perfect combination of
features and performance the restoration industry has been
craving in a desiccant dehumidifier. Designed to operate
vertically or horizontally, the Phoenix D385 provides the
wide operating range and ultra-low grains of a desiccant
with the water removal capacity of the largest LGR’s in
cabinet dimensions identical to our popular Phoenix
200 Max.
The D385 delivers 385 CFM of ultra-low grain process air
and removes an incredible 116 pints per day at AHAM
conditions. The true four hole configuration* allows the
Phoenix D385 to be located in the affected area with the
75 CFM re-activation air stream isolated from the drying
chamber. Three hole designed units** inherently pull
unaffected and/or outside air into the drying chamber. The
D385’s four hole design allows the restoration contractor
to set-up for effective positive, neutral or negative pressure
operation.
Able to operate vertically or horizontally, the D385 will fit
inside most crawlspaces. Having the D385 securely inside,
rather than outside the crawlspace access, deters the
possibility of tampering with the dehumidifier or the set-
up. The 385 CFM of process air will provide 3 ACH on an
affected area up to 7000 cubic feet.
The Phoenix D385 is easy to transport and set-up. The
D385 will fit on your truck in the areas already designed
for your LGR’s and will move around the jobsite with the
same portability. All the power to the unit is provided by two
115 volt grounded power cords. Simply plug the cords into
separate 15 amp circuits. Each cord draws only 11 amps
to power the D385. The re-activation air stream is ducted
through 6” flex duct provided with the unit and stores
conveniently in the top of the unit.
*Having completely separate process and regeneration airstreams.
**Where regeneration airstream is pulled from the process airstream.

2.2 Avoiding Secondary Damages
The D385 is a powerful tool capable of removing a great
deal of water from most environments. Care must be
taken to avoid secondary damages of over-drying and or
unexpected condensation.

drain hose.
The D385 desiccant dehumidifier will continue to remove
objects and or structures.
Care must be taken to avoid secondary damages due to
over-drying.
2.3 Universal Use Set-Up
universal set-up will produce efficient drying, while
avoiding secondary damages. The Phoenix D385 has been
designed with the goal of being easy to use every time.

dedicated capacity available.
The D385 has two separate power cords, each cord must
plugged into the same 15 amp circuit this circuit will trip
when the unit is turned on.
Another situation to avoid is that one or both of the
circuits which the D385 is using can be tripped by other
appliances drawing power from either circuit. This can
happen well after a job site has been set-up as in the case
with a freezer compressor turning on.
Care must be taken to insure that the D385 always has
sufficient power available to run without tripping breakers
or blowing fuses.

The power indicator lamp illuminates to indicate that the
D385 is functioning properly. This indicator is helpful when

2.6C Hour Meter
The hour meter will run whenever your D385 is on.
This digital hour meter measures the cumulative time
of operation in one-tenth hour increments. This non-
resettable time is often used to verify hours on a job or
the timer will continue to hold and display the cumulative
hours run.

2.8 Storage and Transportation
The Phoenix D385 can be transported and stored in either
upright or horizontal positions.
There is a storage compartment under the top cover of
your dehumidifier. This compartment is large enough to

3 Maintenance
3.1 Air Filter Replacement
filters that must be checked regularly.
Process air stream filter:
This 16”x20”x2” filter is located in the top of your D385
underneath the top cover. The stock filter supplied carries
a MERV-11 filtration efficiency rating. This filter prevents
loading the desiccant wheel with foreign matter.
Reactivation air stream filter:
This 12”x12 x1” filter is located in the bottom of your
D385. To change the reactivation air filter, lay the D385
down in a horizontal position. The filter access slot is

dehumidifier’s capacity and efficiency and may cause the
heater coil to cut out on thermal overload.
The filter can generally be vacuumed clean several times
before needing replacement. Replacement filters can be
ordered from the factory or purchased locally if available.
DO NOT operate the unit without the filters or with less
effective filters as the desiccant wheel inside the unit will
