Koolance RP-980SL - Manual (Page 26)

21 User Manual
Under normal circumstances, the liquid coolant does not require replacement. However,
if it becomes contaminated, unclear, or signifi cantly changes color, it must be replaced. A
Koolance “drain valve” (sold separately) is recommended to make that process easier.
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
benefi 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 (through the top fan grill) and use
a can of electronics air cleaner if necessary.
A binder clamp (available at offi 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 refi 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.
