Installation, Operation & Service Instructions

The Phoenix D850 provides the perfect blend of portability,
versatility, and performance the restoration industry has
been seeking in a medium-capacity desiccant dehumidifier.
It combines the wide operating range and ultra-low grains
of the Phoenix 1200 with the portability of an LGR like our
Phoenix 250 Max. The included remote humidistat and
process blower speed control allow you to tailor the drying to
the task at hand.
The D850 delivers 850 CFM of ultra-low grain process air and
removes a stunning 370 pints per day at AHAM conditions.
The true four-hole design* allows for positive, neutral, or
negative pressurization of the affected area. Three-hole
desiccants** inherently pull unaffected and/or outside air
into the drying chamber.
The D850 allows you to connect a remote humidistat
(included), thermostat, or other low-voltage control allow
you to achieve precise conditions anywhere within the
affected area. When the job calls for even deeper drying, the
process blower speed control reduces the process airflow for
maximum grain depression.
The D850 operates vertically or horizontally and will fit inside
most crawlspaces. The lower carrying handle makes moving
the unit into and out of the crawlspace a breeze. Having the
D850 securely inside the crawlspace deters the possibility of
tampering with the dehumidifier or the setup. The 850 CFM
process air stream will provide 3 ACH on an affected area up
to 16,000 cubic feet.
The Phoenix D850 is easy to transport and set up. It will fit
on your truck in the areas designed for your LGRs and will
move around the jobsite with the same portability. Stairs
are a snap thanks to the lower carrying handle. Power to the
unit is provided by either a 30- or 50-amp 230-volt grounded
power cord (both are included). Stow the cords in the on-
board storage compartment for transport. The reactivation
air stream is ducted through 6” flex duct provided with the
unit.
*Having completely separate process and regeneration airstreams.
**Where regeneration airstream is pulled from the process airstream.
