8.2 Technical Data and type plate
Please find the technical data in the annex.
The information on the plate is to be noted when giving statements and for maintenance.
It is located on the side of the chiller.
9.0 Use and function
This water recooling devise is a compact device to which only electricity and hydraulics or
technical water systems still need to be connected and after it has been filled with the coolant it
can be started up straight away.
Cooling of the coolant occurs in an insulated open container with a plate heat exchanger as an
evaporator. The heat absorbed by the refrigerant in the evaporator is released to the environment
by the air-cooled condenser.
The device is used to recool liquid media such as water or brine in industrial or commercial
machines, plant or processes.
Any use other than this is deemed not to be in accordance with the constructions.
If the chiller is to be operated in accordance with the instructions but with water
temperatures of <12°C, then an antifreeze should be added to the water to provide
protection against freezing.
Here it should be noted that although the lower limit of use extends downwards, the
cooling performance changes considerably. Moreover, the pump performance is to be
checked. Please checked to an expert before changing over
The chiller may be operated only with the coolant stated in technical data.
10.0 Installation / Startup
10.1 Installation
The location of the unit should be selected in such a way that it will always be easily accessible
for the operating personnel and that it is not subjected to extreme heat, e.g. near a heating. The
chiller has to be under a roof and protected against humidity. If the unit is to be installed in areas
where there is danger of frost, it must be specially equipped. (optional)
The owner of the cooler must observe the local water protection and noise protection regulations.
The distance between rear side and wall should be at least 700mm
(S7/G7/G8=2000mm). The lowest distance to other surfaces above the refrigerating
plant must not be below 1500mm (S7/G7/G8=5000mm).
Place the unit only on level foundations of good bearing capacity. Align the unit
horizontally and vertically to start-up.
Before you install the unit outdoors or in areas where there is danger of frost, contact
the Manufacturer
