Check that the power supply cable is correctly
connected to both the chiller and outlet. Check that
the power switch is ON. Check that the fuse is intact.

Temperature displayed
is not correct
Water is losing or
gaining heat through
long and/or un-
insulated tubing
Reduce length of tubing, insulate the tubing.
Check for obstructions in tubing
Check that the pump is working
Water may not be circulating through chiller correctly
Chiller does not come on
until aquarium temperature
is several degrees higher
than set point
Temperature offset is
incorrect
Reset temp differential - see instructions below
Water flow through chiller
has slowed
Calcium Buildup
Disconnect chiller from aquarium. Run a 50% solution
of vinegar and water through chiller for 24 hours to
dissolve buildup. Thoroughly flush chiller with Ro/DI
before connecting to aquarium.
Press and hold “SET” for 10 seconds. 1
The display will show a value of 1 to 20 - this is the current set differential
Use the arrow Keys to change the set differential 2
The set differential reflects the number of degrees variance upward
from the set temperature you wish to allow. For example, if you have the
set temperature at 77° F, but do not want the chiller to turn on until it
reaches 80° F, set the differential value to 3. The default setting allows
a variance of 1.5° F from the set temperature before the chiller turns on.
This value is intended to protect the compressor from excessive wear, we
recommend a minimum of 1.5 set differential.
Changing UV Bulb
