INSTRUCTION MANUAL
IMPORTANT SAFETY INFORMATION
WARNING
Read entire manual for important
safety information before using
your KRYO. Failure to follow warnings
could result in injury & void warranty.
Please read this entire instruction manual for important
safety information prior to the use of your KRYO.
Failure to follow these instructions may result
in injury and/or product damage and will void the product
warranty.
GENERAL PRECAUTIONS:
•If the KRYO has just been moved, do not turn on unless
the KRYO has been standing upright for 24 hours. Failure
to do so will void warranty. Stand the KRYO in the upright
position for 24 hours before plugging into the power socket.
•Ensure that there is always at least 4" of clearance on each
side of the KRYO to allow adequate airflow. Not allowing
adequate ventilation will reduce performance, increase
power consumption and void warranty.
•Perform a pressure test on all product lines prior to use.
•Do not run the pump dry. Ensure the pump is always
submerged when in operation. Running dry can damage the
pump.
•Only clean product lines with cold to warm water. Do not
use hot water to clean the product lines.
1

•Let the KRYO sit for at least 24 hours after delivery or after sitting on its side before turning the unit on.
•Whenever the KRYO is operating and cooling the reservoir, the agitator pump needs to be operating to keep the liquid
in the reservoir agitated and avoid ice formation. The pump is wired into the temperature controller and hence should
always be running when the unit is turned on.
Assemble The Sight Tube:
Firmly push the two 3/8" Duotight tee pieces (DUO109) onto the push fit tubes on the front of the KRYO and push
your sight tube into each of the Duotight tee pieces as shown on the diagram on Page 5. Confirm this is held in place
securely by pulling on the Duotight fittings and ensuring they are locked in place. Then, push a 3/8" plug (DUO119)
into each of the Duotight tee pieces.
To remove the plug/tube from the Duotight tee piece, push the collar on the tee piece in towards the fitting as you pull
the plug/tube out of the tee piece.
Attaching A Keg:
1. On the back side of the KRYO you will find two 5/8" threaded shanks. Screw a Duotight Beer Thread Adapter
(DUO104) onto each of the threaded shanks (ensuring the washer is in place internally on the Duotight).
2. Push 8mm OD EVABarrier hose into the Duotight fitting on the shank on the back side of the KRYO.
3. Connect this 8mm OD EVABarrier hose to your coupler or disconnect on your keg.
LEAK TESTING PRODUCT LINES
It is essential to pressure test both product lines prior to running any liquid through them for dispensing.
The product lines need to be pressure tested to a pressure that is at least 1.5 times the pressure that will be used for
dispensing to a maximum of 50 psi. For example, if your dispensing pressure is 20 psi then your product lines should
be pressure tested at 30 psi and your testing pressure shouldn’t exceed 50 psi.
The product lines can be leak tested via multiple methods which are outlined below. It is a good idea to test the system
using multiple methods to be certain the system is holding pressure:
PRESSURE DECAY TEST:
1. Screw a Duotight Beer Thread Adapter onto each all thread shank on the side of the KRYO.
2. Push 8mm EVABarrier hosing connected to a regulated pressure source into one of the Duotight fittings.
3. Set the pressure on the regulator to 1.5 times the dispensing pressure up to a maximum of 50 psi.
4. Turn the gas cylinder o and leave to sit for a few hours. Then check if the pressure on the regulator has decreased
from the set pressure.
If the pressure has dropped, double check that the leak isn’t occurring externally from the KRYO. Check all Duotight
connections and connections to your gas cylinder or regulator with a soapy solution to check for the formation of
bubbles indicating a leak.
If the pressure remains stable then this product line has passed the leak test.
Perform the above steps on the other product line.
AIRLEAK TEST:
1. Fill the reservoir with water.
2. Screw a Duotight Beer Thread Adapter onto each all thread shank on the side of the KRYO.
INITIAL STARTUP & TESTING
2

3. Push 8mm EVABarrier hosing connected to a regulated pressure source into one of the Duotight fittings.
4. Set the pressure on the regulator to 1.5 times the dispensing pressure up to a maximum of 50 psi.
5. Look for the formation of bubbles in reservoir indicating a leak.
Repeat the above steps on the other product line.
HYDROSTATIC LEAK TEST:
1. Empty the reservoir.
2. Screw a Duotight Beer Thread Adapter onto each all thread shank on the side of the KRYO.
3. Push 8mm EVABarrier hosing connected to a regulated water source into one of the Duotight fittings. The
pressure of the water source can be regulated using an in-line regulator for example (D1047) or by connecting a
keg full of water pressurized at 1.5 times the dispensing pressure up to a maximum of 50 psi.
4. Look for any leaks in the reservoir from the product line.
Repeat the above steps on the other product line.
TESTING THE AGITATOR PUMP AND COMPRESSOR
1. With the KRYO unplugged, fill the reservoir with water until all the cooling coils are submerged and the impeller
of the agitator pump is submerged.
2. Plug the KRYO in using the provided IEC cable and turn the red power switch on.
3. Set the temperature on the temperature controller on the front of the KRYO to 35°F
To change any settings on the temperature controller for the reservoir such as temperature hysteresis or calibration
refer to “Adjusting The Dierential” section below.
4. Leave the KRYO for 12 hours to ensure that it drops the temperature of the reservoir to the set temperature on
the temperature controller.
The system has now been tested for cooling and leaks and is ready to be used to dispense from a keg.
ADJUSTING THE DIFFERENTIAL
1. 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.
2. The default dierential setting is 0.5°C, but it can be adjusted if desired.
3. To adjust this parameter, hold the ‘Up’ and ‘Down’ buttons to simultaneously for 3 seconds. The first menu code
F0 will appear on the display.
4. Press the ‘Up’ or ‘Down’ buttons to cycle through the parameters until you reach F3 for the dierential setting.
5. Press the ‘Up’ and ‘Down’ buttons simultaneously to make adjustments to the parameter. Then press either the
‘Up’ or ‘Down’ buttons to change the set value of the selected parameter.
6. Wait 5 seconds and the controller will save your parameter setting and return to normal operation mode.
FILLING THE RESERVOIR
•The pumps are not designed to be run with a glycol concentration higher than 30% hence it is not advised to exceed this
glycol concentration. Doing so may damage the pumps.
The KRYO can be operated with either just water in the reservoir or both water and glycol to reduce the freezing point
of water. IMPORTANT: If you are only using water in the reservoir and not glycol then do not set the temperature of
the reservoir below 35°F.
3

Fill the reservoir until the copper cooling coils are completely submerged. If filling with water only, set the reservoir to
1.6°C (35°F). If using a water/glycol solution, see the chart below for a quick reference of freezing points based on the
concentration of water to glycol. Please note that the reservoir temp should never be set below -2.2°C (28°F), or you
may risk freezing the beer sitting your product lines between pours. The amount of glycol required to be added to the
reservoir depends on the desired set temperature of the reservoir which is dependent on a number of factors including
heat ingress into the entire system, insulation of the glycol lines, ambient temperature, the number of kegs being
cooled and the temperature of the kegs. Use the table below to determine what percentage of glycol you require.
Glycol Volume % Freezing Point Specific Gravity at 21°C
0 32°F (0°C) 1.000
10 26°F (-3.3°C) 1.006
20 18°F (-7.8°C) 1.015
30 8°F (-13.3°C) 1.024
You can measure the glycol percentage using a calibrated refractometer and comparing to the specific gravity at 32°F
in the above table.
We would advise running a 20% glycol solution, as this will be sucient to lower the reservoir temp to the lowest
recommended setting of -2.2°C (28°F), and will give you some runway to top up the reservoir using only distilled
water when needed.
DISPENSING BEVERAGES
Use the diagrams on the following pages determine how to dispense beverages. PLEASE NOTE that the diagrams
are for demonstration purposes only. You may have a dierent style coupler or tap and shank setup to what is shown
in the below diagrams. Fittings other than Duotight fittings can be screwed onto the 5/8" BSP shanks for the product
lines such as:

CARBONATION
The pressure to be set on your regulator diers according to the temperature that the keg is stored at. If the product
is stored at a higher temperature it will require a higher pressure to maintain the desired level of carbonation. Refer to
a carbonation chart to determine what pressure you should be setting your regulator at to reach your desired level of
carbonation based on the ambient temperature the keg is stored in.
For most styles of beer, you should be aiming for a carbonation level of between 2.3–2.8 volumes of carbonation with
the average carbonation level being 2.6 volumes (if you are unsure of the carbonation level of the beer i.e. if it is a com-
mercial keg then assume it is at 2.6 volumes of carbonation). To achieve a specific carbonation level during carbonation
or priming refer to the table below and correlate the temperature of the keg with the desired carbonation level.
NOTE: Do not try to fix a slow or fast pour rate by adjusting the dispensing pressure. This will result in your beer either
going flat or over carbonated. It is best to adjust the beverage line length and diameter. If the pour is too fast and foamy
increase the length of the beverage line between the KRYO and the keg. If the pour is too slow decrease the length of
the beverage line between the KRYO and the keg.
How To Read the Carbonation Chart
First, choose the average temperature of the beer on the left side of the chart, and then find the level of carbonation
you want in the center of the chart. Once you have determined the carbonation level, follow the column up to the top
of the chart to find your PSI setting.

MAINTENANCE
TEMPERATURE CONTROLLER SETTINGS
If the glycol solution has been stored for an extended period of time then it is suggested to replace the solution, despite
glycol having antimicrobial properties. It is recommended to replace the glycol if it has changed color dramatically or
between 12 to 24 months of usage. To replace the glycol solution empty the reservoir using the drainage port and then
refill with the required concentration of glycol using a refractometer to confirm the concentration.
NOTE: Do not try to fix a slow or fast pour rate by adjusting the dispensing pressure. This will result in your beer either
going flat or over carbonated. It is best to adjust the beverage line length and diameter. If the pour is too fast and is
producing a lot of froth then increase the length of the beverage line between the KRYO and the keg. Alternatively,
if the pour is too slow then decrease the length of the beverage line between the KRYO and the keg.
When adjusting your beverage line length to achieve the perfect pour it is always best to start with a longer length of
beverage line as you can always trim a longer length of hose.
For minor flow adjustments, you can use the flow adjustment lever on the included flow control faucets. A flow control
ball lock disconnect (KEG742) can also be used to further reduce the flow rate, although if further flow adjustment is
needed a this point, we would recommend adjusting the length of your beverage lines.
The ice bath temperature controller (located on the back side of the unit) has several functions to help maintain ideal
conditions to chill the beverage you're dispensing.
THE CONTROLLER UNIT ITSELF
IS FAIRLY STRAIGHTFORWARD,
BUT IT’S STILL A GOOD IDEA
TO GET FAMILIAR WITH THE
BUTTONS/FUNCTIONS.
THE DESIRED TEMPERATURE SETTING
THE +/- TEMPERATURE RANGE
KRYO 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 KRYO AGAINST AN
ACCURATE THERMOMETER
Generally, the unit does not need any additional
calibration. However, to find 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 finally, press the POWER
button to lock in the setting.
