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 as a result 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
circulatedfor aminimumof8hours (the longerthebetter if time permits in orderto
assure
thoroughcleaning).
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
(usedin placeofwater); resultingin apropertreatmentwithoutdilution forupto 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).
Filters
There is 10 Micron Particle Water Filter located at the rear of the chiller that should be
inspected every 3 months and
changed when dirty or no longer able to rinse clean.
Refer to User manual for additional info. You should also monitor the laser
tower
temperature to make sure cooling is within specifications.
Water filter replacements can be ordered using P/N 2604-0490.
There is also an Air filter that is located behind the right-hand grill on the power supply
front panel (J40 only). Refer to User Manual for additional info. It should also be
inspected and blown clean every 3 months.
Air filter replacements can be ordered using PN 0129-9322S.
If the laser is not going to be used for an extended period of time, 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.
