Maintenance Agreement

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.

Nalco Mixture

The Nalco Cleaner (P/N 1607-0547) is used to flush your system clean of ferrous metals and
copper alloys because of corrosion. It is recommended as a maintenance procedure that the
chiller/critical cooling loop in each piece of equipment is cleaned and treated 1x per year. The
laser does not have to be lasing. The cleaner should be circulated for a minimum of 8 hours (the
longer the better if time permits to assure thorough cleaning).
The Nalco Solution (P/N 1607-0546) 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,
turn off the laser and drain the water or cooling solution.
Regularly inspect filter on the power supply for any buildup of dust. If dirty, remove the filter
and wash it in clean water. The rate at which the filter becomes more restrictive is mainly
dependent on the cleanliness of the environment.
*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.

Chiller Fluid

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.
CAUTION: DO NOT USE DEIONIZED WATER

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.
