ATTENTION
This IceMaster is designed to manage your
fermentations by cooling water/glycol to
a set temperature in a reservoir which will
then be circulated via a submersible pump
through your specific cooling coils/jacket/
plate/system.
Freezing can occur so icing in the reservoir
is considered normal operation. To
compensate for this we recommend that
one uses a 20% propylene glycol solution
to lower the freezing point.
Unpack your unit and open the top cover to find the
power cord, drain plug, and temperature probes.
Install the drain plug and place the power cord aside
for now.
Plug in the temperature probes to all pump controllers
and attach 3/8" tubing to form a return loop on all sets
of inlets and outlets.
Open the top cover and fill the reservoir with tap water.
Plug in the power cord and flip the red switch to power
on the unit.
Set the temperature for each controller at the front of
the unit to 2°C.
• Hold the ‘Up’ button for 3 seconds until the
number is flashing. The flashing number is your set
temperature.
• While the number is flashing, press the ‘Down’
button to decrease the set temperature or press the
‘Up’ button to increase the set temperature.
• Once you have adjusted the set temperature, wait
for the number to stop flashing and the controller
will return to normal operation mode and display
the temperature probe reading.
The pumps should now kick on and begin recirculating
water through the return loops. Look for water flow
and confirm each pump is operating correctly and
check for leaks around your connections.

to avoid freezing.
Icemaster Reservoir
At the back of the unit, adjust the reservoir
controller to 2°C.
• Hold the ‘S’ button until F1 is displayed.
• Press ‘S’ again, which will enter the temperature
adjustment mode.
• Then hold ‘S’ and the up or down button
simultaneously to alter the set temperature of
the reservoir.
Once you have confirmed that the reservoir is
cooling, the pumps are operating, and you have
no leaks, you are finished with the initial assembly
and testing and can move onto to setting up the
unit with your cooling system.
