Introduction
Congratulations on your purchase of a Spectra-Physics system. This guide describes
pre- installation information for your laser system.
Some preliminary planning is essential to avoid unnecessary delays during installation
and to ensure easy operation and access to your system. You are requested to
carefully consider your operating environment prior to installation. Proper water,
power and room temperature are required for each system.
A checklist of pre-installation considerations is provided in this guide. You are
responsible formeeting these requirements prior to installation, with due consideration
given to all applicable building and safety codes.
We at Spectra-Physics intend to provide you with responsive support so that you
can derive great satisfaction and value in using our systems for your applications.
We are available to you at 1-800-456-2552.

When the system Arrives
Inspection
When the system arrives, any sign of damage to the shipping crates should be brought
to the attention of the delivering freight company. A claim must be filed with that
commercial carrier (usually within 30 days). Notify the originating Spectra-Physics office
of any shipping damage. Shipping damage is not covered by Spectra-Physics.
Your packing list will show all items that you have ordered. Open all the packages and
check each item for possible damage during shipping. Check the items against your
packing list. Some items may have been installed at the factory.
Each system comes with a manual; verify that you have received this item.
Please report any missing or damaged items to Spectra-Physics, or you may contact
your Spectra- Physics Sales Engineer.
Review Instruction Manuals
Please read the manual to get vital information about your system. Familiarize yourself
with the system. You are encouraged to spend as much time as possible reviewing the
system components before your Spectra-Physics Service Engineer arrives for the
installation and training.
Laser SafetyConsiderations
In addition to reviewing the sections in the manual regarding laser safety; be sure to
have the proper safety glasses available for ALL lab personnel present during the
installation and testing of your system. For more information, please call Spectra-
Physics at 1-800-456-2552.
Diagnostics
During the course of installation, power measurements will be demonstrated on all of
the appropriate wavelengths. Your Service Engineer can identify which specifications
will be demonstrated and the equipment necessary to conduct such tests. A non-
standard system will require special consideration.
To have other published specifications demonstrated, consult with your Service Engineer
to determine whether additional diagnostic equipment will be required.

Pre-InstallationConsiderations
Location and Environment
The location of the system and environment of your lab should have the following
features:
A. A safe location that meets all applicable building codes.
B. Easy access with adequate clearance around the instrument.
C. An optical table that will meet the space requirement of the instruments to be
installed.
D. Proper air conditioning could be critical for the performance of the laser. For
certain applications ambient room temperature changes may be an important
factor for the laser system’s performance. Air ducts should not blow directly on
laser or optical path.
E. To ensure stable day-to-day operation, the recommended minimum and
maximum operating room temperatures are 18 - 35°C. Room temperature should
ideally be 22°C. See additional specifications in the User’s Manual.
F. In some applications vibration isolation may be required for your system.
Structural integrity of the flooring could play an important role.
G. Please note that the laser head requires a sturdy and stable optical table.
Consider room requirements for future maintenance and upgrades by your
Spectra- Physics Field Service Engineer.

Utility Requirements
Water
The Millennia system is a closed loop water cooled system and requires no utility water
services. See User Manual for additional information.
Fill the chiller reservoir with distilled water. Do not use deionized water and do not
place the chiller above the laser. Should the unit not be installed properly, and a leak
develops, dripping water may damage the laser. The chiller must always be on when
the power supply is on, even if the diode lasers are not on.
Power Requirements
Electrical
Power Supply Single Phase1
100 to 240 Vic, 50/60 Hz, T 6.3 A, 250 V fuses (two)
Thermorack chiller
Universal Input 100-240 VAC, 50-60 Hz, 9-4 amps max
Two modes of control are offered for the standard Millennia system:
A. A handheld Controller provides local control of the system via an 8-foot cable that
connects to the front of power supply. For more information on the controller,
refer to the User's Manual.
B. For users who prefer to operate the laser remotely, either directly or via a
computer program, a standard RS232 serial link is provided on the power supply
to connect to a computer or terminal.
Both methods are described in Chapter 6 of the User’s manual.

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.

Maintenance Agreement (Continued)
*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.
GeneralProcedures
The chiller operation of the laser system should be checked once a week. The power
output of the system should also be checked once a week by verifying the output
values.
Ifany of the output characteristicshave changed, pleasecall Spectra-PhysicsTechnical
Support at 1-800-456-2552.
