Important notes:
The following picture guide is additional information to the official instruction manual and does
not replace it. The instructions in the manual are to be considered before this document.

Your new KREYER cooling unit has arrived…
First ‘safety’ tip:
Step 1: Condition as delivered - inspect your chiller always on arrival for transport damages. If there
are any – report this immediately to the driver and note the damage on the delivery note before
signing it and keep a copy You will need it to claim transport damages if the shipment is insured.
And now to the installation and start-up:
Step 2: Unpack the unit completely and position it.

Step 3: Take the key (attached to the machine) and open cover panels and the control cabinet - you
will find the instruction manual including the wiring diagram of the machine in your language with
additional instructions regarding the start-up inside of the control cabinet.
Step 4: Read the complete instruction manual carefully.
Please check and compare voltage on the type plate with your local voltage –
if not correlating please contact your supplier!

Step 5: Take a screwdriver and tighten all cable connections inside the control cabinet to ensure
contact in all switches after the transportation.
Step 6: Set all circuit breakers to ON = 1 (they are set to OFF = 0 for safety).
IMPORTANT: Steps 5 and 6 have to be done by a qualified electrician!!

Optional: Overflow protection kit
The units MCK and Chilly Max are 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 24V solenoid valve, a
solenoid connection cable and a non-return valve – available from WTG / KR Y R):
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 below
Insert the solenoid connection cable in the free cable inlet at the back side of the chiller and lead it
through to the control cabinet:

Check the wiring 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:

Step 7: Take the key, open the cover panels. Connect the chiller on the water-side of your installation
(we strongly recommend to install an additional strainer/filter in the inlet pipe connected to your
chiller).
Step 8: Take off the cover of the buffer tank.
Step 9: Fill in the water (observe the water quality as described in the instruction manual) and check
the water level in the sight glass.

Step 10: If you are operating your chiller on set temperatures below +8°C (= +46,4°F) you need to fill
in food safe glycol. We suggest a concentration of about 30% glycol relating to the total water
content (e.g. water inside the buffer tank of the chiller + piping system + double cooling jackets or
cooling plates). Glycol is also required if the ambient around chiller can be below 0°C.
It is recommended to add glycol also in units that do not cool to low degrees due to its corrosion and
bacteria prevention qualities.
Step 11: Bleed the pump -> remove the bleed screw and reinstall and tighten it as soon as medium
exits from the filler fitting.
Step 12: Equip the machine with the right local plug. It is absolutely essential to use a plug with the
right amperage. Plug it to its socket – the main switch of the unit stays in OFF-position.
IMPORTANT: Steps 12 and 13 have to be done by a qualified electrician!!

Step 13: Measure and ensure that the chiller is connected in the right rotating field (clockwise
rotation).
Step 14: If you completed correctly all steps before you can now close the control cabinet and turn
on the main switch to start the operation of the chiller.
Pictures below: While the unit is running you will also find two indications of the right rotating field
on the pump: a directional arrow (pump turning in same direction as arrow shows = right) and a
small colour-indicator made of plastic (black visible = right direction; white visible = wrong direction).
Additionally there is on most of the units fans a directional arrow as on the pump (fan turning in
same direction as arrow shows = right).

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 instruction manual.
Step 15: 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.
While operating the unit take a screw driver, open the casing of the differential pressure switch and
adjust it corresponding to the description in the instruction manual. Afterwards close the casing of
the pressure switch and close all open cover panels of the unit.
The chiller is now successfully adjusted and ready for use!
