1. Safety instructions
1.1 Installation and commissioning
Place the unit on a plain, dry and clean place.
Before switching on the unit, leave it standing on its feet for 24 hours to ensure
that the oils that may have been circulation during transport have settled.
Pay also attention that the connecting cable is untangled and free and that nothing is
resting on it. For direct product cooling use the cooling coil offered by the manufacturer
only (optional item). It is imperative to provide sufficient ventilation of the unit. The
ventilation slots must remain free for sufficient evacuation of heat. No objects may be
placed under the unit!
The following safety measures must be observed:
Min. water temperature: -6 °C (with propylene glycol)
Max. water temperature: +30 °C
Max. ambient temperature: +32 °C
ATTENTION: For cold water temperatures below 0 °C it is mandatory, to add
30 % of propylene glycol to the cooling water !
Note: There can be no ice bank building when using Glycol.
Keep the unit clean from any dirt, fiber etc.
Make sure to connect the unit to the required supply voltage
Protect the unit from moisture, no fluids may enter the electric parts
Observe the warning and safety information on the electrical components and in
this instruction manual
1.2 Safety information
The unit should be connected and operated by trained personnel. Adjustments,
maintenance and repairs should be performed by qualified personnel.
Correct function and reliability of operations of this unit can only be warranted, if during
operation and service the general common saftey precautions, as well as the specific
safety instructions described in this manual will be carefully observed.
Handling and treatment of the unit not according to the safety instructions required for
electrical appliances and the instruction in this document may result in severe bodily
harm which is not under the responsibility of the manufacturer. Injury and property
damage can accure through:
inappropriate operation
incorrect installation or operation
improper removal of the necessary protective cover or housing, wetting the electrical
parts
Opening of the unit during operation, which is prohibited

1.2.1 Impairment of safety
If the unit is damaged, it must be unplugged, set aside, marked to warn others against
using it, and a technician must be called before it is returned to operation. Using the
unit if it is damaged is unsafe and therefore stricktly prohibited.
1.2.2 Safety instructions
The unit may only be operated after an appropriate protection earth has been
connected, and the directions of the country of destination, regional regulations as well
as manufacturer’s safety instructions have been observed.
1.3 Spare parts
If assemblies or parts are replaced, only use identical assemblies or parts from the
manufacturer.
1.4 Transport/Storage
Check your unit for damaged on arrival, and note any damages found in the delivery
note before signing for it, so you may claim the from the transport company. Postpone
commissioning it until you have consulted with the manufacturer. The unit may only be
stored in a dry, dust-free environment at temperature of 0°C to 40°C.
1.5 Electrical installation
All electrical installations are to be carried out by qualified personnel, under the
conditions:
The electrical unit has been unplugged from the electric socket and secured
against unintentional resetting
Disconnection from electric power has been verified.
It is ensured for the operation of this control system that also the additional
designated monitoring and saftey fuse has been installed in a professional manner.
The installation is made with compliance to national and the manufacturer’s safety
standards.
1.6 Service
All information in this instruction manual regarding service work must be strictly observed.
2. Intended use
The cooling units MiniCHILLY are suitable for the cooling of process water for cooling other
appliances such as tanks. The cooling units are only authorized for the above mentioned
range of application. They are not suitable for cooling hot liquids, chemicals or the like.

5
3. Commissioning
1) Remove the lid and fill the water tank with water (see water level gauge outside).
Never operate the unit with a liquid level beneath the lowest water level mark
“min”!
2) Connect the water pipes, check for possible leaks.
3) The unit is designed to operate with a tank temperature control kit which includes a
submersible pump and plastic tubes to lead Glycol water through it. The fittings on the lid
of the unit should be used to connect the plastic tubes. Such kits are not provided with
the unit. If used, please connect them according to the instructions of the manufacturer.
4) Close the lid.
Do not operate the unit when it is open with the lid removed!
5) Establish the electric network connection (see 1.5 Electrical installation)
6) Adjust the required temperature on the thermostat (see 5. temperature setting). After
reaching the adjusted set-point temperature the unit is ready for operation (see also 1.1
safety measures).
3.1 Connection
Verify that all connections are sealed. No dirt particles may gain access into the pipes and
the cooling water in the unit.

4. Decommissioning
Switch off the unit and disconnect the power plug.
Remove the pipes/hoses from the unit.
Draining and cleaning of the unit by qualified personnel.
5. Temperature setting
Thermostatic operation: adjust the desired set-point temperature at the controller (5).
Do not operate the unit when it is open with the lid removed!
Make sure that the lid is fastened before switching the unit on!
For ice bank building
Ice bank will be build approx. 2 hours after starting the unit
Building an ice bank requires filling the unit with clear water only, without Glycol or
remnants of Glycol in the water system
Recommended set-point temperature for using an ice bank: -1,0 °C (30,2 °F)
ATTENTION: to avoid damage on the unit (freezing of items such as pumps)
make sure that during the ice bank building all items are removed from the
water tank
=> Never let the working machine unattended over a longer time
For required cold water temperatures down to -6 °C (21,2 °F)
Using the MiniChilly to produce cold water below the freezing point down to -6 °C
(21,2 °F) necessitates the use of a glycol-water mixture (min. 30 % propylene glycol,
max. 35 % propylene glycol in the water system)
No ice bank building is then possible due to the anti-frost qualities of the glycol

The value you see on the diplay after
starting the unit is the current water
temperature
1. Press the button SET for 1 second
(The set value will start flashing after
a few moments)
2. Increase or decrease the value using
the arrow button UP or DOWN
3. Press SET again to confirm the new
value
Now you will see the current water
temperature again.
The controller is enabled for a temperature range from -1°C to +20°C to protect the
machine.
For cooling temperatures down to -6°C use a glycol-water mixture
(approx. 30 % propylene glycol)!
Please pay attention that the water bath temperature must not fall below -6°C
and must not exceed +30°C!
Controller activation for a minimum set-point down to -6°C
Press the „Set“-Button for 3 seconds
„PS“ is displayed => confirm by pressing „Set“ again for a short time
With the arrow buttons input password „22“ and confirm with „Set“
Select parameter name „r1“ (minimum set-point) by confirming with „Set“
With the arrow buttons set the parameter (min. set-point) down to -6°C
=> confirm again with „Set“
After modification press „Set“ for 3 seconds to save the settings
After this setting the set-point can be adjusted as usual (see pictures above) –now
possible down to - 6°C.

6. Cleaning of the cooling unit
Casing: Before cleaning the units disconnect the mains plug! Please do not use water
directly on the unit, clean only with a wet cloth and a little dish liquid. The cleaning of
the units and the beverage coils (optional for this unit, if used) have to take place
according to the instructions of the industrial safety regulations.
Prevent any moisture from getting into the electric part of the unit!
The condenser fins should be cleaned at regular intervals (min. every six months and
more frequently if required) by qualified personnel to remove the accumulated air dust.
