Selecting a Location
•The two-station dryer should not be located in basements, outdoors or unheated
rooms. If adequate air circulation in the space is not available, the unit should be
converted to ducted operation. Placement in unvented or sub-grade internal rooms
with limited air movement can create mold or mildew conditions.
•The drying cabinet can be located within 1-2” of a wall, provided that 10-12” of
clearance is available on the sides to open the door fully.
•Position the dryer on a level floor.

Levelling the Dryer
•The dryer is provided with (4) adjustable feet. These feet can be adjusted using a
standard adjustable wrench. If the foot retaining nut or top nut have loosened, they can
be re-secured using a 15/16” wrench and 15/16” deep socket.
•The cabinet will “twist” during levelling. Confirm the proper alignment of the door in the
frame during levelling. The door should not bind or swing on its own when the cabinet is
properly levelled.
•Door alignment will vary from the pallet to the floor and small adjustments in the feet
will effect the final level of the door.
Understanding the Model Number
The drying cabinet is shipped pre-configured for the expected power supply. Look for the
placard inside the door of the cabinet to determine the configuration of the cabinet.
Figure: Electrical Placard
It is important to correctly match the power supply to cabinet specifications otherwise damage
or injury may result.

Converting the Dryer to external Ducting:
Drying cabinets work best when the moisture laden air is moved away from the vicinity of the unit. This
can be through an external wall or into a larger apparatus bay with suitable air make-up or
dehumidification.
•The unit is provided with a galvanized fan cover for un-ducted applications.
•Lock-out the unit or unplug from the power supply.
•Remove the (4) #12 self tapping screws and take the cover off the unit dryer
roof.
•The venturi outlet for the fan is 12 3/8” diameter. A standard 14” to 12” or 14”
to 10” collar transition may be used. The collar should be fixed vertically into the
roof of the cabinet, avoiding the fan blade inside the cabinet.

•The diameter of the ducted tube should not be restricted less than 10” in diameter.
•Runs longer than 10’ may require the use of a booster fan (not included) to ensure
pressure losses are overcome.
•An external self-closing louvre should be utilized to keep out pests and rain water.
•The use of legacy “square or rectangle” ducting is permitted, considering a minimum
dimension of 8” x 16”.

MAINTAINING DUTY GEAR
Your new drying cabinet is a key part in meeting the NFPA 1851: Standard on Selection Care
and Maintenance of Structural Firefighting Protective Ensembles.
Proper drying is critical for the maintenance and longevity and safety of duty gear. By properly
preparing and utilizing the Firehouse Express Dryer, it is possible to return gear to service
quicker and in better condition than other methods.
Preparation:
•Ensure that the gear has been properly cleaned of all contaminants through the proper
selection and use of detergent and PPE washing systems. Contact Ready Rack for more
information regarding total cleaning cycle products.

•Boots, gloves and hoods can be placed on either hangers or directly on the mesh
shelving units. Ensure each item is straightened and not twisted.
•For simple drying activities where the gear has not been soaked or rinsed, pants, jackets
and liners can be hung as a set. The Firehouse Express dryer will process the equipment
as-is. Examples of this can include non-hazardous response calls where simple sweat or
humidity is introduced to the gear. Allowing moisture to remain can cause steam burns
should a rapid heat up of the gear occur.
•Where equipment is very wet or has been separated for mechanical washing, hang the
paints and jackets, with the liners separate. For single or double sets of gear, separating
will reduce the overall cycle time to complete drying.
Drying:
Proper drying relies on a number of conditions, many of which are under the users control. The dryer
controls will ensure that the equipment is not overheated, the operator can choose to use ambient or
heated air depending on the conditions within the firehouse.
•Ensure the gear is organized in the cabinet when loading.
•Check that the doors(s) are correctly closed and the seals are in good working condition.
•Balance the amount of gear to be dried to the conditions. A warm humid station will take longer
to dry than a dry station.
•Using a proper extractor will require less moisture to be removed by the cabinet.

Post-Drying:
•Ensuring that the gear is properly stored is important to maintaining clean and dry and
protected. Utilizing a duty gear hanger or locker will ensure the gear is protected from dirt and
debris, as well as preventing mildew build-up.
MONTHLY INSPECTION
•Clean and remove all debris and dust from inside the cabinet. Remove plenum from floor and
clean underneath.
•Check for missing screws or guards.
•Check unit for level and adjust feet as necessary.
•Check the shelves and sliders for burrs and wear. Check that the sliders are secure.
•Check all hanging rails supports for security.

START/STOP is pressed indicating contactor is closed. (See
Contactor)
Open rear tunnel cover and check for damaged wiring or
damaged copper strips
Check continuity of snap disc. “OL” indicates break
Limited Heating / Excessive Dry
Time
Unit may have high ambient temperature.
Unit may have gear loaded unevenly or with very high
water content. Check that cleaning process or extractor is
working correctly.
Check rear panel with IR Gun to determine if cold spots
exist across elements. May indicate burnt or damaged
element.
Remove rear panel and individual check resistance reading
(ohms) of each element. Original reading is marked on
element. Should be between 48-58 ohm.
Check ducting, plenums and inlets for blockages.
Contactor Not Closing
Check connection (Blue and White Wires) to pull down and
check for +12V between terminals when active. May
indicate control board relay failure
Press contactor button to determine is circuit will close
manually. May indicate either control board relay or if the
contactor will not manually close, a failure of the contactor
No Fan
