BrewBuilt IceMaster Max 4 User manual

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 specic 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 nd 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 ll the reservoir with tap water.
Plug in the power cord and ip 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 ashing. The ashing number is your set
temperature.
• While the number is ashing, 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 ashing 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 ow
and conrm each pump is operating correctly and
check for leaks around your connections.

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 conrmed that the reservoir is
cooling, the pumps are operating, and you have
no leaks, you are nished with the initial assembly
and testing and can move onto to setting up the
unit with your cooling system.
Assembly And Testing Instructions
ICEMASTER MAX 4
Thank you for purchasing the IceMaster refrigeration
unit. You are taking a big step to better manage
fermentation temperatures, and ultimately making
cleaner, more consistent beverages.

Quick Setup
Adjusting The Differential
Fill the reservoir with a 20% propylene glycol
solution: 4 parts RO/distilled/deionized water to 1
part 99.9% propylene glycol.
• If you choose to use water only, it is best to use
tap water. RO/distilled/deionized water on its
own may damage the heat exchanger.
Plug in both temperature probes. The temperature
probes must be plugged in at all times, otherwise
you will get an error code.
Connect your cooling system outlet hose to the IN
bulkhead.
Connect your cooling system inlet hose to the OUT
bulkhead directly to the right.
Install the temperature probe in your thermowell,
or tape it directly to the outside of your vessel if it
does not have a thermowell.
The temperature dierential controls at what
point the pump will power on to begin a cooling
cycle. For example, if your SET temperature is 20°C
(68°F) and the temperature probe reading rises
to 20.5°C (68.9°F), the pump will power on and
recirculate cooling solution until the probe reading
drops back down to 20°C.
The default dierential setting is 0.5°C, but it can
be adjusted if desired.
To adjust this parameter, hold the ‘Up’ and ‘Down’
buttons simultaneously for 3 seconds. The rst
menu code F0 will appear on the display.
During normal operation, the number displayed
on the pump controller is the reading from the
temperature probe.
Adjust the SET temperature on the controller to
your desired fermentation temperature.
• To adjust the SET temperature, hold the ‘Up’
button for 3 seconds until the number is ashing.
While the number is ashing, press the ‘Down’
button to decrease the set temperature or press
the ‘Up’ button to increase the set temperature.
Wait 3 seconds and the controller will save the
setting a return to normal operation mode.
To adjust the reservoir temperature settings, please
see the instructions on the following page.
Press the ‘Up’ or ‘Down’ buttons to cycle through
the parameters until you reach F3 for the
dierential setting.
Press the ‘Up’ and ‘Down’ buttons simultaneously
to make adjustments to the parameter. Then press
either the ‘Up’ or ‘Down’ buttons change the set
value of the selected parameter.
Wait 5 seconds and the controller will save your
parameter setting and return to normal operation
mode.

The ice bath temperature controller (found on the opposite side of the pump controllers, just
below the upper vents) has several functions to help maintain ideal conditions to control your
fermentations.

THE DESIRED TEMPERATURE SETTING
THE +/- TEMPERATURE RANGE
IceMaster will cycle on/o to keep its
temperature within the set range of the
set temperature - example: if you set the
temperature at 5°C with +/- 0.5 the unit will
cycle on/o over a 1°C range at 4.5°C and
5.5°C. The lowest setting is 0.3°C.
COMPRESSOR DELAY TIME IN MINUTES
This feature protects the unit from turning on/
o too quickly, and potentially damaging the
compressor. The range is from 1-10 minutes
with the default set at 3.
CALIBRATES THE ICEMASTER AGAINST AN
ACCURATE THERMOMETER
Generally, the unit does not need any
additional calibration. However, to nd
the correct adjustment - place an accurate
thermometer in the unit and compare against
the controller readout. If needed, set the
calibration on the controller +/- by the number
of degrees it is o. This will ensure the unit is
adjusting to your desired temperature properly.
TO MAKE CHANGES TO ANY
OF THE FUNCTIONS
Hold down the Sbutton until
F1 shows on the controller,
release the button.
Select the desired function by
clicking the UP or DOWN arrows
until the controller shows the
correct function number.
Press & hold the Sbutton while
using the UP/DOWN arrows to
adjust to your desired setting.
Release the Sbutton.
And nally, press the POWER
button to lock in the setting.

MAINTENANCE/
CLEANING
To ensure the unit
continues to properly
function it is good
practice to dust/clean
the heat exchangers
every 6 months.
IceMaster does not turn on
IceMaster does not seem
cold enough

IceMaster seems to make
too much noise
Check temperature setting by placing a thermometer inside reservoir.
Check aer 30 minutes & compare against set unit temperature.
Calibrate with F4 function on controller as needed.
Check set temperature range. Adjust F2 function on controller
to a higher range.
Ambient room temperature is too high, so unit is working harder
to cool to set temperature.
Humming is normal and gurgling sounds are caused by cooling
liquid used by the unit. The unit may not be not level.
Check circuit breaker or fuse ; Check plugs.
