Assembly
A Firefly dryer consists of several modular assemblies
which are joined together to create a complete conveyor
dryer unit. Common modules are:

Assembly Step 1: Ensure Adequate Clearance
Before placing the Firefly modules, it is important to
ensure adequate clearance will be available for both the
main footprint of the machine and maintenance access.
Since the Firefly Curing System is a modular system, the
main footprint of the machine depends on the exact
configuration you purchased. Consult your salesperson
for an engineering drawing of your particular system.
Clearance is required around the heat modules in order
to open control panel doors, pull out filters, and clean
camera boxes. See Figure 7 for specific clearance
numbers.
Figure 7: GENERAL CLEARANCES
Clearance is also required for the heat modules to slide
on their tracks for maintenance access to the center of
the machine. Ensure that nothing blocks the movement
of the heat sections front/back as shown in Figure 8.

Assembly Step 2: Identify and Arrange
Using the figures in this manual, identify the modules
that shipped with your dryer. Arrange the modules in the
location you wish to install the machine in the correct
orientations for your system. Below is a standard
configuration for a 2 heat section system. As the Firefly
system is a modular system, your configuration may be
different. Consult with Brown Manufacturing for the
exact layout of your system.
Use the leveling legs on each module to bring all the
sections to the same height and level. Shift the modules
as necessary to create a single, straight frame.
Figure 9: STANDARD MODULE ARRANGEMENT
Assembly Step 3: Connect Modules
Remove the cover grills from the frames of each section.
Bolt each module to each adjoining module using the
connection holes at the end of each frame.
Figure 10: FRAME CONNECTIONS
Assembly Step 4: Mount Accessories
Depending on the exact configuration of your system,
you may have to locate and set into position some or all
of the following accessories:
- Load Detect Sensor(s)
- Scanners (Mount on scanner stands)
- Height Sensors
- TV (mounts on TV stand –Figure 9)
Assembly Step 5: Install Belts
First, loosen the Belt Tracking Knobs (Figure 11) on
both the front and rear of the machine. Slide the rollers
as far back as they will go.
Figure 11: LOOSENING BELT TENSION
Next, run the belt through the body of the machine. The
belt may have a flap covering the seam. Make sure when
the seam is on the top side of the roller, the attached side
of the flap is on top and moving in the direction of the
belt (Figure 12)

Figure 12: SEAM FLAP ORIENTATION
Each end of the belt has a row of eyelets. Line up eyelets
together, and push the connector pin through (Figure
13).

Assembly Step 6: Connect Power
Warning: This equipment is operated by high voltage
electrical power and can be dangerous. Only a
qualified electrician should connect and service this
equipment. Safe and proper installation of this dryer
is the customer’s responsibility.
Note: The wiring of the electrical supply to the dryer
must be in accordance with all local, state, and
national codes.
A main disconnect with overload protection, capable of
switching the dryer’s full pull load must be installed
within reach of the operator.
Each heat section module has an independent power
supply that must have an independent overload current
protection device not exceeding the MAX OCP rating on
the supply information tag on the control panel.
Some modules require two independent power supplies
that must each have an independent overload current
protection device not exceeding the MAX OCP rating
on the supply information tag on the control panel.
Each heat section control panel has a disconnect switch
located inside the panel. Panels with two power supplies
will have two disconnect switches. Wires may enter
through the supplied hole at the bottom of the panel, or
the customer may elect to punch a hole in the sidewall of
the panel. Connect supply power directly to the open
terminals of the disconnect switch, and a ground wire to
the grounding lug located adjacent to the disconnect
switch.
Figure 14: CONTROL PANEL POWER HOOK-UP
Assembly Step 7: Connect Control Kiosk
The control kiosk connects to the logic control panel
using three cables – a standard 120V power cable, a
VGA cable, and a USB cable. Connect these wire to any
compatible ports on the main logic control panel.
Assembly Step 8: Venting
Venting of the dryer exhaust air is recommended. The
garments that are cured in this oven will smoke and this
will remove most of the smoke from the printing area.
♦Vent the exhaust air flow to the outside of your
building with standard 10” diameter duct.
♦Long duct runs and changes in duct direction
restricts the air flow. Under certain
circumstances an in-line booster fan may be
required.
♦The exterior end of the duct should be protected
from direct winds that may cause back drafts.
Precautions should be taken to prevent rain
water from entering the duct work.
Assembly Step 9: Wire Machine
The machine has several internal connections between
components that are disconnected for shipping, and must
be reconnected to finish installation. Due to the technical
nature of these connections, it is recommended only a
Brown Technician perform the final wiring operations.
Please refer to Appendix A for machine wiring
diagrams.

Machine Adjustments
Belt Tension
It is normal for a new belt to stretch within the first year
of its life. That is why it is essential to maintain a
centered position. Monitor to see if the belt drifts a
certain direction and the rate at which it drifts. This will
indicate which side of the roller to adjust and the amount
it will need to be adjusted.
The side that the belt drifts towards indicates the side
that needs to be tensioned. The faster a belt drifts, the
more it needs to be tensioned [on the drifting side]. Keep
in mind that it is possible to over tension a belt. To
check, grab the edge of the belt (near one of the rollers)
and try to shift it on the roller. If it cannot be moved, the
belt is over tensioned.
Belt Tracking
Belt tracking is adjusted with the red knobs on the end of
the conveyor frame. Remember, increasing the belt
tension on one side will cause the belt to track towards
the opposite side of the dryer frame. Decreasing the belt
tension on one side will cause the belt to track towards
that side. Additional adjustments may be required when
the oven reaches full temperature or as the belt stretches
with wear.
Load and Object Detectors Adjustment and Cleaning
The load sensors and object detection (trip) sensors
must work correctly for proper operation of the machine.
These sensors send an invisible beam of light to a
reflective target located under the belt. The beam is
reflected by the target and detected by the sensors. A red
light above each sensor is activated when the sensor
detects the target. If the target is not detected when
nothing is blocking the beam, the sensor lenses and
target should be cleaned with a rag. Mild solvents may
be used to clean off stubborn deposits. Sensors must be
pointed at targets, and targets must be located directly in
the line of sight of the sensors.
Height Sensor Adjustment and Cleaning
The height sensors on the Firefly operate in
emitter-detector pairs shown in Figure 1. One sensor
emits a visible red laser beam, while the paired detector
senses the beam. If an object blocks the beam, the
machine stops the belt and alerts the user to a height
sensor error. The height of the beam may be adjusted by
moving the sensors up or down in their mounting slots.
A yellow light on the detector indicates detection of the
emitted beam. The emitter and detector pairs must be
aligned such that the beam is always triggering the
detector when nothing is blocking the beam. It may be
necessary to clean the lenses on the emitter/detector
pairs if foreign debris accumulates on the lenses.
