3.11 Connecting the Exhaust
Tools and Materials Needed
• 254 mm (10 in.) Duct
• Exhaust Blower
• Auxiliary Fan (if duct is over 5 meters in length)
To connect the exhaust duct:
NOTE The customer must provide the exhaust blower and associated ductwork.
1. Install the facility ventilation duct on the UV-9 Cure Module exhaust port and clamp in place.
The UV-9 Cure Module has one internal blower per module. The internal blower is
sufficient if the duct length from the UV-9 toward the outside is under 5 meters.
2. If the duct is over 5 meters in length, install an auxiliary fan.
Table 3-3 lists internal and extraction exhaust flow rates.

NOTE The extraction flow rate must be measured in the UV-9 exhaust duct with the UV-9 Cure
Module on and at full power.
Sufficient exhaust flow is required to cool the UV lamp. The internal blowers are driven by an inverter to
adjust the cooling. Two flaps, mounted next to the exhaust port, operate as a differential to ensure proper
cooling to the UV source. Make sure not to block the flaps. They must move freely.
Figure 3-8 Exhaust Port
WARNING! CAUTION!
An external dry contact is required. This dry contact must be positive for
extraction and negative when it is turned off. An insufficient extraction flow rate
can cause a lamp default and components to overheat. If an external contact is not
used, the warranty is null and void.

3.11.1 Exhaust Fan Rotation Direction
To check the rotation direction:
1. Disconnect the blower hose to see the impeller (Figure 3-9).
2. Turn the Main Power Switch located at the back of the UV Cure Module to the
ON (l)
position.
3. Press the relay KM3 inside the electrical cabinet.
4. Verify that rotation matches the direction of the arrow.
5. After confirming proper rotation, turn the Main Power Switch to the
OFF position (0).
6. Reconnect the blower hose.

3.12 Pneumatic Connection (Shutter Option)
If the UV-9 Cure Module is equipped with shutter (entrance and/or exit), it must be connected to the
pneumatic system.
1. Pneumatic specifications are listed below:
• Air pressure: 0.6 MPa (87 psi)
• Connecting pipe: 6 mm
• Consumption: < 0.02 m
3/H
2. Set the pressure regulator to 0 MPa.
3. Verify the facility air pressure is off (0).
4. Connect the facility air hose to the pressure regulator.
5. If not already connected, connect the air hose to the facility air supply.
6. Set the facility air supply to 0.6 MPa (97 psi).
7. Set the pressure regulator to 0.35 MPa (50 psi).
The “green” needle is for the pressure sensor; the black needle is the actual set pressure
with the filter regulator.

3.13 Post-installation Functional Testing
After installation has been completed, the Nordson ASYMTEK service technician will perform all testing
necessary to ensure quality performance of your UV-9 Cure Module.
NOTE As a precaution, the UV lamp is not pre-installed at the factory. It will be installed on-site
by the Nordson ASYMTEK technician. See 6.5.2 UV Lamp Replacement.
