3.4 Ducting
The duct requirements of the 4800E are much more critical
than those of refrigerant-based dehumidifiers.
ALL SUPPLY
AND RETURN AIR DUCTING FOR THE 4800E MUST BE
AIR AND VAPOR TIGHT.
This is extremely important for
proper performance. Ensure that reactivation discharge air
does not enter the process or reactivation inlets.
Using excess duct length significantly reduces air flow volume
through duct. This is true in any application. If the job at hand
needs a short length of duct, cut a section to the appropriate
length. If air flow is restricted by excess length, performance
will suffer. The same can be said of excess bends in the
ducting.
Two different duct sizes are used on the 4800E. All ducting
materials are available from Therma-Stor LLC
(see accessories list in Section 1).
Process inlet / Reactivation inlet: 18” flex duct.
To attach flex ducts to the process air intake, push the wire
of the first few loops beyond the 2 holes in the duct collar.
Push the metal rod through the duct and duct collar piercing
the duct in two places. Tape or a hose clamp can be used
to create an airtight seal. Alternatively, the duct wire can be
pushed past the weld beads on the duct collar and the duct
can be secured with hose clamps or ratcheting straps. If
using only one inlet connection, the other can be left closed.
Process outlet: 18” flex or lay flat plastic duct.
To attach flex ducts to the process air outlet, push the wire
of the first few loops beyond the 2 holes in the duct collar.
Push the metal rod through the duct and duct collar piercing
the duct in two places. Tape or a hose clamp can be used
to create an airtight seal. Alternatively, the duct wire can be
pushed past the weld beads on the duct collar and the duct
can be secured with hose clamps or ratcheting straps.
When using 18” lay flat ducting, slip over the outlet collar and
zip-tie or duct tape in place.
Reactivation outlet: 10” flex duct.
To attach flex duct to the reactivation air outlet, push the
wire of the first couple of loops beyond the weld beads on an
outlet collar. Secure with hose clamp.
3.5 Avoiding Secondary Damage
The Phoenix 4800E is a powerful tool capable of removing
a great deal of water from most environments. Care must
be taken to avoid secondary damage of over-drying and or
unexpected condensation.
The Phoenix 4800E removes vapor water from the
incoming process air stream and transfers it to the outgoing
reactivation air stream. 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 exhaust from reactivation air stream cools below its
dew point, 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.
The Phoenix 4800E does not produce liquid water internal
to the machine. There is no condensate pump and no drain
hose.
The 4800E 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 damage due to over-
drying.
3.6 Electrical Requirements
A 480 volt, 3 phase power source is required to operate the
Phoenix 4800E.
All local and state codes must be strictly adhered to and
good electrical practices should be followed to achieve the
best installation possible. The 4800E must be properly wired
to an adequate power source. Serious damage to the motors
and controls can occur if incorrect voltage is applied.
(See
Electrical Schematic
drawing in the back of this manual
for internal wiring.)
4 Operating Instructions
Refer to the Operating Instructions label located next to the
control panel of your 4800E.
User-supplied power cord, cord grip, and branch protection
appropriate for the electrical load must be supplied. See
device for FLA rating.
The Phoenix 4800E dehumidifier comes complete and ready
for operation. All that is required is to provide the proper
power source and duct connections (described above).
4.1
Connect and Start-Up Procedure
1) Lockout Power Source.
2) Wire unit 480 Volt 3 Phase.
3) Verify Selector Switch is set to STANDBY.
4) Engage Power Source and turn Main Disconnect to ON.
5) Verify PHASE OUT light is off, if not, re-wire power
source to correct phase order.
6) COOL DOWN light will come on for 5 minutes.
7) Set Selector Switch to RUN.
8) Set process damper to obtain a maximum of 1.5”
water column pressure as read on pressure gauge.
