4. Connect the gas supply line from the Model 3910 purge unit to the
nitrogen supply. Make sure you use dry, oil-free, Electronic Grade 5
(or better) nitrogen (99.999% pure) to prevent contamination of the
Model 3910 or your laser optics.
Use the 2 m,
1
/8 in. i.d. PTFE gas supply line provided to connect the
Model 3910 to the nitrogen supply. It comes with a Clip-Lok connector
on both ends.
a. Attach one end of the gas supply line to the INPUT FROM GAS CYL-
INDER
connector on the Model 3910.
b. Attach the other end of the gas supply line to your nitrogen supply.
If your nitrogen supply does not accept a Clip-Lok connector, cut
off the existing connector and install your own. A Clip-Lok con-
nector for
1
/4 in. i.d. PTFE tubing is also included in the accessory
kit.
To attach barbed connectors to PTFE tubing, heat the tubing with a
flameless heat source (heat gun), then quickly slide the tubing onto
the barbed fitting while the tubing is still warm. Do not move the
connection until it has cooled. Install the line and check for leaks.
This completes the installation of the Model 3910 purge unit.
Removing the Purge Line
from the Laser Head and Model 3910
To release the purge line from the laser head, press inward on the metal
locking flange on the quick-disconnect, while gently pulling on the hose.
To release the purge line from the Model 3910 purge unit, press inward on
the wire clip-spring while gently pulling on the hose.
Installing the Tsunami Model 3955
Electronics Module
If you have a Lok-to-Clock system, install the Model 3930 at this time.
Refer to Chapter 8.
1. Verify the power switch on the rear panel is off.
2. Verify the voltage select switch on the rear panel is set to match the ac
line voltage of your facility outlet.
The white indicator for the voltage setting is located next to the power
cord connector. Voltage choices are 100, 120, 220, and 240 Vac. If the
voltage setting does not match your facility outlet voltage, refer to
Appendix C, “Setting the Line Voltage Switch,” to reset it.
Do not connect the Model 3910 to a boil-off tank or other non-lab-grade
nitrogen gas source, nor to any source with a pressure greater than
67 kPa (10 psi), or damage to the filters will result
