Dear Chilly user – Brewer, winemaker, hobby user!
Congratulations on your new CHILLY unit !!
The following guide includes pictures to show you the step-for-step installation
and start-up of your new Chilly to help you get started fast and easy.
Pic.1: Your new CHILLY would be delivered secured on a pallet with protective foil and safety bands, eventually
in carton packaging.
Please check at arriving on possible transport damages and claim these immediately to the transporter.
If you are not sure please unpack the unit together with the transporter.
Transport damages cannot enforcement later!!
Correct place of installation:
In a well aired room.
If set outside, the unit should be under an awning or in a shed providing protection from the elements
(sunshine, rain, snow) and well aired.
The unit operates between the ambient temperatures:
Min. +10°C / 50°F
Max. + 42°C / 107°F
Distance / placement:
Free space in front of the cool air intake min. 0,5 meter / 2 feet
Free space in front of the hot air outlet min. 1,0 meter / 3,5 feet
For exact installation conditions, please refer to the manual.

Pic.2: When unpacking the Chilly, you will find its official Instruction Manual . This Manual pertains to your
specific unit by means of its Serial Number. The electrical diagram in this manual pertains to your unit.
Unit Serial Number appears on the name plate attached to it (8 digit number).
Pic. 3: View inside of the open tank – the heat-exchanger (evaporator) in spiral type is visible

Pic. 4: Fill the tank with clear water
Pic. 5: Add ‘food-safe’ grade glycol (anti-frost protection) to the water. The concentration of the Glycol in the total
quantity of water in your system depends on the water temperatures you want to set your Chilly to produce, and
the instructions from the Glycol manufacturer. Typically, you need to have about 25% - 30% of Glycol part in the
total quantity of water in your system. (Necessary for low temp Chillys, if ambient temperature can reach negative
temperature or in case of cooling below +8°C is needed)
Pic. 6: Controlling the level of filled water/glycol-mix in the sight glass - it should always be between MIN
(minimum) and MAX (maximum), also when the unit is in full operation.

If the water level went down after you started using the unit and water is circulating in your tanks – top up the
water and make sure to add Glycol in the right quantity as well!
Pic. 7 + 8: Connection of the systems water pipes/hoses to the chiller. At this point the valves are closed and
pointing upwards (see arrow direction).

Pic. 9: Bleeding of the pump (letting out air from the pump) – disconnect the tube/hose of the chiller
water outlet and open the outlet valve . At first the water will flow out in spurts. Keep the valve open
until the water comes out in a constant flow. This tells you that all air has been pushed out of the pump
by the water. Close the valve again and top up the water in the tank if necessary. Remember your
Glycol!
Attention: Please check the pressure capacity of the unit pump. Please ensure that all
components in your water system are compatible with the maximum pump pressure. If

necessary, use pressure-reducer elements (e.g. bypass-valve) in your water system. Pump
capacity and further information are inside the unit manual.

Pic. 10: Reconnect the tube/hose to the chillers outlet. Then open both valves
(The valves are open when they are parallel to the tube, see arrows).
Optional: Overflow protection kit
he unit CHILLY is working as an open water system. Water users (e.g. tanks) should be installed on
the same level as the chiller or below to avoid an overflow of the chillers buffer tank when the
unit/pump is off.
If this isn’t possible you should install an overflow protection kit (consisting of a solenoid valve, a
solenoid connection cable and a non-return valve – available from WTG / KREYER). For the right
voltage of the solenoid valve respect absolutely the available control voltage of the chiller –> check
inside the electrical diagram appearing at the end of the instruction manual.

Kreyer – Picture guide to installation and start-up Chilly (page 9of 18) v.11-2015
Install the non-return valve in the outlet pipe/flow line (for the right fitting position respect the flow
direction indicated by an arrow on the non-return valve) and the solenoid valve in the inlet
pipe/return line of your chiller (see picture in the example below
Insert the solenoid connection cable in one of the free cable inlets at the side of the chiller (see green
arrows -> remove one of the pre-cut openings + install a screwed cable gland) and lead it through to
the control cabinet:

Kreyer – Picture guide to installation and start-up Chilly (page 10 of 18) v.11-2015
Check the electrical diagram of the chiller appearing at the end of the instruction manual where to
connect the cable of the solenoid valve (in this example here the contact inside the control cabinet is
X2 -> clips 5, 6 and 7=earth). It doesn’t matter whether you connect the brown or the blue cable to
clip 5 or 6:
Please check and compare volage on name plate with your local voltage – if not correlating
please contact your supplier!

Pic. 11 + 12: Take the plug and connect it to your power supply.
Note: Chilly units are used in many countries. It can happen that your unit comes with a plug
which is not the standard in your country. You may need to replace the plug on the unit to your
local type.

NOTE:
Please close the lid of the Chilly unit when you have finished the installation
The unit should operate when the lid is closed for proper transfer of cold air from the fan
into the condenser
By open lid, the air sucked into the unit is drawn from the warm ambience all around the unit, and not only through
the fan which cools it properly on the way to the condenser. This may cause in some cases a stop due high-
pressure, and may reduce significantly the cooling capacity of the unit, so low temperatures may not be reached
as set.
Keep lid closed while the unit is in operation!

Parameter to change temperature from °C to °F (regulator ELIWELL ST120):
-Press and hold for longer than 5 seconds
-Search “PA2” by pressing or and confirm with
-ype “22” by pressing and confirm with
-Search “diS” by pressing or and confirm with
-Search “dro” by pressing or and confirm with
-Select the unit of measurement used when displaying the temperature recorded by the
probes with or : value 0 = °C, value 1 = °F and confirm with
-Press to return to the standard operation menu
IMPORTANT NOTE: switching between °C and °F DOES NOT modify the SEt, diF values etc
(e g Setpoint=10°C becomes 10°F)
Optional: Differential pressure switch
Installed in most of the CHILLYs in the USA
When the pump pressure is correctly set adapted to your tank installation - the integral pump inside
the cooling unit would switch-off when all tank valves are closed and there is temporarily no
requirement for cooling/heating -> this needs to be adjusted.
o adjust take a screw driver, open the casing of the differential pressure switch (installed nearby the
pump) and adjust it corresponding to the description in the instruction manual. Afterwards close the
casing of the pressure switch and close the open cover panel of the unit
