4.0 Maintenance Requirements

To maintain a valid warranty on your Spectra-Physics system, it is necessary for the customer to
assume the responsibility and perform the routine maintenance program. Failure to do so may
result in the warranty being voided.

4.1 Chiller Maintenance

The chiller fluid level should be appropriate for the model laser and must meet Spectra- Physics
specification requirements. Insufficient cooling could result in a decrease of performance or
damage to the laser system. Chiller coolant should be checked monthly and chiller filters should
be cleaned every 6 months and the chiller coolant changed every 6 months.
The Nalco Circulating solution is a premixed liquid corrosion inhibitor designed for use in closed
loop cooling systems. It can be added directly to a closed cooling system (used in place of water),
resulting in a proper treatment without dilution for up to 6 months (even if the pink tracer turns
clear). This solution is a complete inhibitor that protects ferrous metals and copper alloys from
corrosion. It is nitrite free and minimizes the challenge of bacteria control (depending on
environment and usage).
If the laser is not going to be used for an extended period of time, turn off the laser and drain the
cooling solution.
*NOTE: to restrict the growth of algae in the reservoir, it is recommended that the reservoir cover
be kept in place and that all circulation lines be opaque. This will eliminate the entrance of light
that is required for the growth of most common algae.

4.2 Head Filter

The Purge Filter should be replaced when the humidity >10%. This filter has an average lifetime
greater than one year depending on the relative humidity and the temperature of the operating
environment.

4.3 General Procedures

The chiller operation of the laser system should be checked once a week. The power output and
the mode-locking of the system should also be checked once a week by verifying the output
values. If any of the output characteristics have changed, please call Spectra-Physics Technical
Support at 1-800-456-2552 with the model and serial number of the laser.
