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 Differential” 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 differential 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 differential 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 differential 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.
