The function of the dehumidifier is to remove moisture (in
the vapor state) from an air stream. This is accomplished
by exposing the air to an adsorbing media (desiccant) in
a sealed air stream (process). After the desiccant has
adsorbed moisture, it is exposed to a second air stream
at an elevated temperature (reactivation). This causes
the moisture to be driven out of the desiccant preparing it
for more moisture adsorption. This process is done on a
continuous basis, providing a constant drying process. The
two air streams (process and reactivation) are separated
by seals, which contact the desiccant media. Figure 1
illustrates the relationship of the seals and airflow pattern.
The dehumidifier is designed with the two air streams
flowing in opposite directions (counter flow) thereby
maximizing the energy efficiency of the equipment.

air from outside the drying chamber, while the Process Air
Outlet is ducted into the chamber.
Proper installation is critical to the performance of the
Phoenix 1800DX. Follow the guidelines below to maximize
service life and performance.
3.4 Ducting
To get maximum performance out of the 1800DX
desiccant dehumidifier, ALL SUPPLY AND RETURN AIR
DUCTING 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. Be sure that the return air duct
connection(s) is physically sound, is sealed to the
appliance casing, and terminates outside of the trailer.
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.
All ducting materials are available from Therma-Stor LLC
(see accessories list in Section 1).
3.1 Inspection
Thoroughly inspect the machine to ensure no damage
has occurred during transport or on the job site. Check
for any obvious signs of deterioration of the 1800 device.
Examine the base of the 1800 for signs of sagging, gaps,
or cracks between the base and the trailer floor.
3.2 Location
Note the following precautions when locating the Phoenix
1800DX:
Trailer must be located outdoors with reactivation outlet
pointed away from open windows or building fresh air
inlets. Position trailer for shortest, straightest duct run
to structure. Provisions for adequate combustion and
ventilation air must be provided in accordance with section
5.3 of the National Fuel Gas Code ANSI Z223.1.
Always ensure the 1800DX is located with the reactivation
outlet pointed such that the reactivation air exhausts
to the atmosphere in an unoccupied area and can NOT
be drawn into any nearby structure. Do not exhaust
reactivation air across walkways or towards buildings,
openable windows, or building openings. Do not allow
the reactivation outlet to become obstructed by snow,
construction debris, etc. Maintain a minimum 4’
clearance around electric and gas meters, regulators, and
relief equipment. Locate device a minimum of 10’ from
combustible constructions. Be aware that reactivation air
contains flue gasses that, over time, can degrade some
building materials. Do not connect device to a chimney
flue serving a separate appliance designed to burn solid
fuel.
Do not direct process or reactivation air streams toward
any Propane-gas container within 20’ (6m).
Process inlet: 14” flex duct. (356mm)
To attach flexible ducts to the process air inlet, push
the duct wire past the metal flange on the 1800DX duct
collar. Secure with hose clamps or ratcheting straps. If
only using one inlet connection, seal second connection.
Process outlet: 14” flex or lay flat plastic duct.
(356mm)
To attach flexible ducts to the process air outlet, push
the duct wire past the metal flange on the 1800DX duct
collar. Secure with hose clamps or ratcheting straps.
When using 14” (356mm) lay flat ducting, slip over the
outlet collar and zip-tie or duct tape in place.
3.5 Avoiding Secondary Damage
The Phoenix 1800DX is a powerful tool capable of
removing a great deal of water from most environments.
Care must be taken to avoid secondary damage of overdrying and or unexpected condensation.
The Phoenix 1800DX 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.
Always ensure the 1800DX is located with the
reactivation outlet pointed such that reactivation air will
NOT be drawn back into the structure.
The Phoenix 1800DX does not produce liquid water
internal to the machine. There is no condensate pump
and no drain hose.
The 1800DX 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.
3.3 Set-Up
When conditions warrant the use of a desiccant
dehumidifier, use one of the setups described below to
achieve efficient drying, while avoiding secondary damage.
Review Section 2.1 to understand the desiccant drying
process. Always ensure the 1800DX is located with the
reactivation outlet pointed such that reactivation air will
NOT be drawn back into the structure.
Neutral Pressure Setup
Many drying applications require neutral pressure
operation. In this setup, the Process Air Inlet pulls air
from the affected area (drying chamber) and returns dried,
processed air to the affected area via the Process Air
Outlet.
Positive Pressure Setup
For Positive Pressure operation, the Process Air Inlet pulls

Cool Down Procedure
5.5 Alarm (Light and Horn)
The alarm indicator lamp illuminates (and horn sounds) to
indicate that a fault condition exists. The fault conditions
could be:
• Motor overload
• Reactivation temperature greater than 375°F (190°C)
(possibly due to low reactivation airflow)
• No dehumidification (i.e. saturated wheel)
Failure to follow COOL DOWN PROCEDURE may result in
damage to unit due to overheating. ALWAYS follow COOL
DOWN PROCEDURE before shutting unit down.
1) Set Selector switch to OFF and wait for COOL DOWN
light to come on.
2) Process blower and burner should be OFF.
3) WAIT for COOL DOWN LIGHT to go OFF (5 minutes).
4.3
An external alarm can be wired to terminals 52 and 58.
This will provide 115VAC during an alarm condition.
Shut Down & Disconnect Procedure
6 Maintenance
1) Verify COOL DOWN LIGHT is not illuminated and
Cool Down Procedure has been followed.
2) Close gas valves. (valve on LP tank and valve
inside trailer)
3) Turn Main Disconnect switch to OFF.
4) Unplug power cord.
Note: Be sure the gas is turned off at the propane supply
cylinder when the 1800DX is not in use.
6.1 General Maintenance
A definitive time schedule should be established for
inspecting all rotating parts and components. Inspection
requirements depend on the frequency of operation,
transport, and operating conditions. Periodically check
the condition of the air filter, rotating parts, and fasteners
to ensure they are secure and in proper working order.
Periodically check airflow to make sure there are no
obstructions to airflow in outlet or inlet ductwork.
Recommended minimum inspections:
• Upon installation
• After 1 week of operation.
• Annually thereafter or upon loss of performance
to include combustion system and be performed by a
qualified servicer.
5 Control Panel
5.1 Main Disconnect
The Main Disconnect switches power from the source to
the panel. Power must be disconnected at the source
prior to accessing control panel. Access to the control
panel with power applied is ONLY by qualified service
personnel.
Power is present up to disconnect even in OFF position.
Disconnect power at the source before opening panel.
Note: The appliance and its inidividual shut off valve must
be disconnected from the gas supply piping system during
any pressure testing of that system at test pressure in
excess of 1/2 PSIG (2.5 KPA).
5.2 Power Light
6.2 Cabinet
The POWER indicator lamp illuminates to indicate that
power is supplied to the control panel.
Disconnect power before removing access panels.
Remove panel fasteners and panels from unit to access
internal components. The condition of the cabinet gaskets
should be observed during inspection and servicing to
insure a good seal. Any leaks must be sealed and panels
securely fastened for proper dehumidifier operation.
Burner compartment may be cleaned by removing burner
access panel and using compressed air to loosen
contaminants. Follow up by vacuuming loose debris.
5.3 OFF-ON Selector Switch
When the Selector Switch is moved to the ON position, the
reactivation blower and burner are started and the 1800DX
begins dehumidification. The 1800DX will continue to
dehumidify in all conditions until the power is turned off.
No dehumidistat is provided to monitor process inlet air
condition (see over-dry warning section 3.5). An external
control (dehumidistat, thermostat, or other contact) can be
wired in place of the jumper across terminals 55 and 56.
The external control must be a dry contact switch designed
to operate a 115VAC circuit.
6.3 Filter
The maintenance interval for the filter depends directly on
the cleanliness of the air entering the dehumidifier. It is
suggested that a program be established to assure that the
filters are replaced or cleaned prior to becoming clogged to
the point they create a system problem.
Two air filters (16”x16”x2”) (406mm x 406mm x 51mm)
must be checked regularly. One filter is located at the
5.4 Run Light
The Run light will illuminate when the OFF-ON Selector
switch is in the ON position. This light indicates the unit
is dehumidifying. The Run light will go out if an external
control is being used and there is no demand.

process air inlet. The other one is located
at the reactivation air inlet.
Wash aluminum filters with fresh water.
Clean the filter from the downstream side,
forcing debris toward the filter inlet. Dry the
filter completely before installing it in unit.
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 become clogged
and require disassembly to clean.
6.4 Blower and Motor
Blower and motor bearings are permanently
lubricated and do not require maintenance.
Blower wheel - inspect wheel blades for
accumulation of dust and dirt. Clean
thoroughly with compressed air and or
vacuum. The wheel should not strike the
housing or the inlet ring. Make sure wheel is rotating in the
proper direction.
Figure 5
and contact with petroleum based airborne particles can
reduce the efficiency of the desiccant media. The preferred
method of cleaning is to blow dust out with compressed
air. Proper filtration and preventing contact with chemicals
will greatly improve the life of the desiccant. Inspect the
face of the media to see that no surface damage has
occurred. If damage is noticed, please contact ThermaStor at 1-800-533-7533 for assistance. The rotor should
turn smoothly upon the shaft, if not check the support
bearings.
6.5 Drive Motor
The media drive motor is permanently lubricated and
requires no maintenance.
6.6 Rotor Drive Belt
A spring loaded tensioner keeps the belt sufficiently
tensioned. Check the belt for signs of excessive wear.
Replace as necessary.
6.9 Fuel Cylinder
6.7 Seals
To remove LP cylinder for inspection, recertification, or
replacement, first disconnect the copper pigtail between
the cylinder and the pressure regulator. The tank is held in
place by rods through the lifting eyes and bolts through the
floor and frame. Note that cylinder is arranged to provide
vapor withdrawal only. After reconnecting the cylinder,
perform a leak check by opening the tank valve and
probing the joints between the tank and regulator with a
flammable gas detection device or spray joints with a leak
detecting fluid (soap/water solution) and watch for any
bubbles to form. Fix any leaks before operating device.
High temperature seals separate the process and
reactivation compartments. Normally, the seals will not
require service or replacement. However, should damage
occur, or if poor performance as the result of an air leak is
suspected, the following inspection must be performed to
determine whether the seals should be replaced:
Inspection:
1) Turn the unit off and remove the access covers.
2) Visually inspect for gaps between the desiccant media
and the seals.
3) If significant gaps, wear, or damage are observed,
the seal needs to be replaced.
6.8 Desiccant Media
The silica gel desiccant media supplied with the
dehumidifier will last indefinitely under normal conditions.
Due to the nature of desiccants they make very good
filters. The life of the desiccant is directly related to the
airborne contaminates passed through it. Atmospheric
contaminants, exposure to acidic gases/or air streams,

Phoenix 1800 DX Desiccant Dehumidifier Limited Warranty
Warrantor:
Therma-Stor LLC
4201 Lien Rd.
Madison, WI 53704
Telephone: 1-800-533-7533
Who Is Covered: This warranty extends only to the original end-user of the 1800 DX Desiccant
Dehumidifier and may not be assigned or transferred.
First Year Warranty: Therma-Stor Products warrants that, for one (1) year the 1800 DX will operate
free from any defects in materials and workmanship, or Therma-Stor Products will, at its option, repair
or replace the defective part(s), free of any charge.
End-User Responsibilities: Warranty service must be performed by a Servicer authorized by ThermaStor Products. If the end-user is unable to locate or obtain warranty service from an authorized
Servicer, he should call Therma-Stor Products at the above number and ask for the Therma-Stor
Products Service Department, which will then arrange for covered warranty service. Warranty service
will be performed during normal working hours.
The end-user must present proof of purchase (lease) upon request, by use of the warranty card or
other reasonable and reliable means. The end-user is responsible for normal care. This warranty
does not cover any defect, malfunction, etc. resulting from misuse, abuse, lack of normal care,
corrosion, freezing, tampering, modification, unauthorized or improper repair or installation, accident,
acts of nature or any other cause beyond Therma-Stor Products’ reasonable control.
Limitations and Exclusions: If any 1800 DX part is repaired or replaced, the new part shall be
warranted for only the remainder of the original warranty period applicable thereto (but all warranty
periods will be extended by the period of time, if any, that the 1800 DX is out of service while
awaiting covered warranty service).
UPON THE EXPIRATION OF THE WRITTEN WARRANTY APPLICABLE TO THE 1800 DX OR ANY PART
THEREOF, ALL OTHER WARRANTIES IMPLIED BY LAW, INCLUDING MERCHANTABILITY AND FITNESS FOR
A PARTICULAR PURPOSE, SHALL ALSO EXPIRE. ALL WARRANTIES MADE BY THERMA-STOR PRODUCTS
ARE SET FORTH HEREIN, AND NO CLAIM MAY BE MADE AGAINST THERMA-STOR PRODUCTS BASED
ON ANY ORAL WARRANTY. IN NO EVENT SHALL THERMA-STOR PRODUCTS, IN CONNECTION WITH THE
SALE, INSTALLATION, USE, REPAIR OR REPLACEMENT OF ANY 1800 DX OR PART THEREOF BE LIABLE
UNDER ANY LEGAL THEORY FOR ANY SPECIAL, INDIRECT OR CONSEQUENTIAL DAMAGES INCLUDING
WITHOUT LIMITATION WATER DAMAGE (THE END-USER SHOULD TAKE PRECAUTIONS AGAINST SAME),
LOST PROFITS, DELAY, OR LOSS OF USE OR DAMAGE TO ANY REAL OR PERSONAL PROPERTY.
Some states do not allow limitations on how long an implied warranty lasts, and some do not
allow the exclusion or limitation of incidental or consequential damages, so one or both of these
limitations may not apply to you.
Legal Rights: This warranty gives you specific legal rights, and you may also have other rights which
vary from state to state.
