3 Operation
3.1 How the Phoenix D385 works
Your Phoenix D385 has two separate air streams that run
through it – Process (Fig. 1) and Reactivation (Fig. 2).
Note: Check for airflow at all inlets and outlets. DO NOT run
unit if no airflow is detected.
Process Air Stream:
P1 –
385 CFM of air enters (12”flex) the top of the machine
and...
P2 – ...
water vapor from incoming air is deposited on the
desiccant wheel.
P3 –
385 CFM of dry air exits (10” lay flat) the machine.
Reactivation Air Stream:
R1 –
75 CFM of air enters (6”flex) the lower-side of the
machine and...
R2 –
passes over the heater coils.
R3 –
Water vapor is picked up from the desiccant wheel by
the hot air and...
R4 –
...75 CFM of wet air exits (6”flex) the machine.
3.2 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.
Your Phoenix D385 removes vapor water from the incoming
process air stream (Fig. 1) and transfers it to the outgoing
reactivation air stream (Fig. 2). The reactivation exhaust air is
hot and wet.
Take care to prevent the reactivation exhaust air stream
from causing secondary damage due to condensation.
If the reactivation exhaust air stream cools below its
dewpoint liquid water will condense inside the duct work
creating puddles. If the reactivation exhaust air stream is not
exhausted completely from the structure it can also cause
secondary water damage.
Your Phoenix D385 does not produce liquid water internal
to the machine. There is no condensate pump and no drain
hose.
The D385 desiccant dehumidifier will continue to remove
water from already dry, cold air. It is possible to over-dry
objects and or structures.
Care must be taken to avoid secondary damages due to
over-drying.
3.3 Electrical Requirements
When used on a water loss work site, ground fault circuit
interrupter (GFCI) outlets are required.
Your Phoenix D385 requires a total of 24 amps, 115VAC. In
order to run at all, this machine must be plugged into two
separate circuits each with a minimum of 12 amps dedicated
capacity available.
The D385 has two separate power cords, each cord must be
plugged into its own 15 amp circuit. If both cords are 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.
If your location requires the use of an extension cord, use
safe techniques in selection and connection. Such cords
must be grounded and rated for carrying 12 amps: 14 gauge
minimum for one extension less than 25ft in length or 12
gauge for one extension less than 50ft in length.
