Water Treatment/Filtration
Local water conditions may require the installation of
a water treatment system to inhibit scale formation,
filter out sediment, and remove chlorine taste and
odor. Consult your local distributor for information
on Manitowoc’s full line of Tri-Liminator filtration
systems.
FILTER REPLACEMENT PROCEDURE
Tri-Liminator systems include a pre-filter and a
primary filter. For maximum filtration efficiency,
replace the primary filter cartridge every six months.
If the filter gauge reading drops below 20 psig prior
to six months usage, replace the pre-filter first.
1. Turn off the water supply at the inlet shutoff
valve.
