Replacement
Do not disassemble water lines or remove cartridges where spilled water
could contact equipment that requires electrical service. Electrical shock
hazard could result.
Warning Depressurize system prior to opening cartridge access door.
s
Note For more demanding applications where low TOC water is required,
allow the water to recirculate past the UV lamp for at least an hour before
drawing off product water.
s
Note The two flanges on the end cap should be able to slide down on each
side of the keyway wall.
s
Note The cartridges will still contain water when removed. Therefore, you
will want to have a sink, bucket or other waterproof container available to
place them in after removal.
s
Note If your feedwater has large quantities of particulates, we strongly
recommend installing/using a Thermo Scientific external pretreatment
assembly in the feedwater line which contains a high volume 5 micron
sediment cartridge along with anti-scalant. If in doubt about your
feedwater, contact Technical Services for a W.A.T.E.R. sample test kit.
