User Manual
For preventative maintenance, Koolance recommends replacing the liquid coolant
every 2 years. A Koolance “drain valve” (sold separately) can make that process easier.
The liquid should be immediately replaced if it ever becomes contaminated, unclear,
or signi
fi
cantly changes color. Although uncommon, biological growth and corrosion
are substantially easier to prevent than clean-up.
If you are upgrading or removing a cooling block in your system, please follow the
instructions below.
Adding Coolers & Maintenance
CAUTION
:
Any time a hose is disconnected with coolant still inside,
leaking can occur. Before doing so, it is highly recommended to
remove all computer hardware and the power supply. It can also be
bene
fi
cial to keep a large towel directly beneath the work area (within
the chassis) to absorb any free liquid.

Radiator Performance
Over time, dust will accumulate on the radiator. While the cooling system may
continue to operate in this condition, performance can decrease. To keep the
system clean, check the radiator periodically (under the top cover) and use a
can of electronics air cleaner or blower if necessary.
A binder clamp (available at of
fi
ce supply stores) is helpful for keeping a hose folded
while removing or adding coolers. Even so, pressure within the cooling system is
such that liquid will not easily
fl
ow out unless relieved elsewhere-- for example, by
opening the reservoir re
fi
ll plug.
Bend the hose directly before and after the section to be worked on. Place a binder
clamp on both bends, or tie them in this position to help avoid
fl
uid loss. There
will
be some liquid exposed; do not operate on the cooling system in this manner near
or above electronic hardware.
