Prepare for Shipment
It is anticipated that in OEM applications the Patara laser will be installed in
another system that will be shipped internationally. The Patara optical assembly
must be properly prepared for shipment if internal damage is to be avoided due to
possible freezing of trapped water in the coolant lines. This procedure follows:
1.
Ready a dry gas source in preparation for draining the system. Oil-free, dry
filtered air or (N
2
) is recommended.
2.
Remove coolant connections from back of laser housing.
3.
Connect a dry gas line to the
COOLANT OUT
connector on housing.
Coolant lines must be purged in the proper direction or trapped water may
remain in the lines inside the laser. If this trapped water freezes it can cause
lines to leak water when operation is resumed.
4.
Connect a drain hose with a proper quick disconnect fitting to the
COOLANT
IN
connector on the housing.
5.
Purge the lines with for at least 1/2 hour at 5 psi.
6.
Remove purge lines.
After the laser is dry place it in a sealed ESD bag with a desiccant. Package the
laser securely in a shipping container.
All water will need to be removed from the chiller prior to shipment. Refer to the
chiller manufacturer’s instructions. Do not reconnect chiller lines to laser prior to
shipment. After shipment, if antifreeze was used, drain and clean the chiller. Add
a new filter and clean Optishield Plus coolant before reconnecting the chiller to
the laser.
