BrewBuilt IceMaster Max 4 Manuale utente

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.

TIP -If you plan to use a propylene glycolIf you plan to use a propylene glycol

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.

CONTROLLER BASICS

•To turn on/o - hold the POWER

button down for few seconds.

•The readout on the controller will

show the temperature (Celsius) of

the liquid inside the IceMaster.

•To check the temperature setting

- press & hold the UP arrow.

•To check the dierential

(+/- range from the set temp) -

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 shuts o/on

too oen

IceMaster is always on

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.
