1.0 General Product & Safety Information
1.1 Product Information
The CRD216SS is designed to expand stiffer tubing such as nylon, polyethylene,
polypropylene and Teflon tubing. With the heater off, the unit can also expand flexible
tubing up to a durometer of Shore A 85 (Shore D 35), including any non-metallic braided
materials
The minimum/maximum inside tube diameter is .040” –1/2”
The unit operates up to a temperature of 350 °F
The standard jaw sets are universal and are designed to be used with an inside diameter
range of .040” to 1/2". Other jaw sets are available that are optimized for a specific size
(see accessories page at www.cleanroomdevices.com or call Clean Room Devices, Inc.).
The unit design allows for simple operator adjustment
1.2 Safety Information
This product uses an air cylinder and foot pedal to pneumatically actuate and expand the
jaws. The unit is not intended to expand anything other than flexible tubing.
Avoid placing your fingers between the upper jaw block and the air cylinder
mounting bracket while operating unit, sufficient pressure exists to cause personal
injury.
After heating up, the metallic areas in and around the jaws will be extremely hot.
Avoid direct contact with the jaw set while the heater is on. Surface will be hot
enough to cause severe burns.

2.0 Installation
Ensure all five (5) rubber feet are completely stabilized on your work surface prior to applying
air pressure to the unit.
2.1 Air Supply
Connect a 1/4” air supply hose to the inlet on the pressure regulator. The air supply
should be free of moisture and contaminates and provide a minimum of 100 psi.
The regulator on the unit should be set to 80-120 psi.
2.2 A/C and DC Power
This product uses standard 60Hz alternating current power provided by your local utility.
Ensure that you use the correct power supply (120VAC/24VDC) for the type of power in
your region. The heaters and digital controllers are powered by the 120VAC power
source, and the time-delay circuitry is powered by the 24VDC power source. Both must
be present to operate.
2.3 Connection Setup
Connections on the CRD216SS are simple. Refer to Figure 2.3.1 below when making all
connections to the back panel.

Jaw Set
Thumb Wheel Locking Hex Nut
CAUTION: THE UNIT CAN BECOME EXTREMELY HOT. CARE MUST BE USED
AT ALL TIMES WHEN EXPENDING AND DURING JAW INSTALLATION AND
REMOVAL.
To adjust the jaws for the size tubing to be expanded you need to first loosen the
Locking Hex Nut.
With A/C power and compressed air attached to the expander, depress the electric foot
switch to activate the expander. Adjust the expander lower jaw to the position you want
using the Thumb Wheel Knob.
Turning the Thumb Wheel clockwise will increase the jaw expansion size, counter
clockwise will decrease the jaw expansion size. This adjustment may require fine tuning
depending on your tubing I.D., O.D., durometer and/or material.
Once you have the expansion size you want tighten the Locking Hex Nut to secure the
adjustment. Release the foot pedal.
Place the tube over the ends of both expander jaws and hold firmly in place.
Actuate the Tube Expander by pressing the foot pedal.

Once the tube is expanded, release the foot pedal, rotate the tubing 90 degrees on the jaws
and actuate the Tube Expander by pressing the foot pedal again.
Note: Several expanding actions may be necessary to effectively expand the end of
the tube for the fitting/connector to slide in. Each time you expand the tubing
remember to rotate the tubing 90 degrees on the jaws.
Once the tube is expanded satisfactorily, release the foot pedal and immediately complete
any secondary assembly application before the tubing regains its original size.
3.1.A Using the Jaw Hold-Open Feature
A Jaw Hold-Open switch has been installed on the tubing expander. This makes setting
the gap between the jaws much simpler.
1) With the toggle switch in the “ON” position, flip the jaw hold-open switch to the
“ON” position (UP).
2) Use the foot pedal to trigger the cycle. The upper jaw will retract and remain open.
3) Flip the jaw hold-open switch to “OFF” position (DOWN) and the upper jaw will
return to the non-expanded position.

3.2 Jaw Installation and Removal
CAUTION: THE UNIT CAN BECOME EXTREMELY HOT. CARE MUST BE USED
AT ALL TIMES WHEN EXPENDING AND DURING JAW INSTALLATION AND
REMOVAL.
Tools required are 3/8”, 9/16”and 11/16”open ended wrenches, 2mm, 2.5mm, 3mm,
4mm and 3/32nds hex wrenches.
Remove the two 4x8mm screws attaching the Thermocouples to the upper and lower jaw
using a 2.5mm hex wrench. Figure 3.2.1 and 3.2.2 Note: Be sure to label each
thermocouple and/or heater cartridge as to its position, upper or lower, and be sure to
replace them in the correct positions. The unit will not operate correctly otherwise.
Figure 3.2.1 Figure 3.2.2
Turn the thumb wheel clockwise until the cylinder shaft is fully extended in the jaw block
channel to remove force from cylinder shaft. Figure 3.2.3

Figure 3.2.3
Using a 3/8” open end wrench to hold the flats on the cylinder shaft and an 11/16”open
end wrench on the hex nut, break the upper jaw nut loose by turning it counter clockwise.
Figure 3.2.4
Using a 9/16 open end wrench break the lower jaw nut loose by turning it clockwise.

Now remove the two 5x20mm screws holding the front cylinder mount bracket using a
4mm hex wrench. Figure 3.2.6.

Place two fingers under the cylinder shaft and lift until the upper jaw clears the lower
jaw. Figure 3.2.7 and 3.2.8
Figure 3.2.7 Figure 3.2.8
Use a 2mm hex wrench to loosen the set screws in each jaw and then remove the heating
element probes. Figure 3.2.9 and 3.2.10

Flip the cylinder backwards until it stops. Figure 3.2.11
Figure 3.2.11
Rotate the upper jaw by hand turning it counter clockwise until the jaw can be removed.
Important note: when screwing upper jaw onto cylinder shaft it is important to only
screw the jaw 1/2 to 2/3 of the way on. Any farther and the jaw may slip off the jaw
block when the cylinder is retracted.
Loosen the locking hex nut and grab threaded rod by hand and rotate threaded rod
counter clockwise while holding the lower expander jaw until the jaw is removed. Figure
