Chiller requirements
Caution:
the cooling system must have a filter that allows the coolant to meet the
specifications for particles shown below. Failure to use a filter capable
of meeting the particle requirements can cause damage to expensive
optical components and could be cause for denial of warranty claims on
these components.
Coolant
Acceptable types of coolant Distilled water
Drinkable tap water
Water/glycol mixture (see “Usage of inhibitors/additives” below)
Deionized water is NOT allowed
