As more parts are cleaned, the IPA gradually becomes more
concentrated with liquid resin, reducing the eectiveness of Form
Wash. As IPA evaporates, add fresh IPA to keep the fill level between
the minimum and maximum lines. Use the hydrometer to check the
IPA resin concentration between cleaning cycles, and replace IPA
as needed for the cleanest parts.
As the IPA resin concentration increases, the weight will float higher,
and the stem and O-ring will rise. For a smooth, dry surface finish,
replace IPA when the O-ring rises above the float’s tall wings.
Checking IPA Resin Concentration
To check whether the IPA is suitable for cleaning parts, lower
the mount, open the outer lid, and float the previously calibrated
hydrometer in the wash bucket. Note the alignment of the O-ring
relative to the float’s wings.
MAINTENANCE
Change IPA if O-ring
is above tall wings.
CAUTION: Wear gloves when handling parts
and surfaces with IPA or uncured resin.
