Summer Operation Cooling Only
Winter Operation Cooling and Heating
◊ Make sure that the temperature sensors (condenser,
supply and discharge / protection against freezing)
are in the correct positions and that the water lines
are connected properly to the input and output.
◊ One important prerequisite is that all lines are filled,
ventilated and have been checked for leaks. The
system pressure can be read on the outside of the
unit on the manometer. The system pressure may
be a maximum of 2.5 bar. Initial pressure during
non-operation 1.5 – 2.0 bar.
◊ If the system is being operated with antifreeze, make
sure that the concentration is correct.
◊ The electrical lines of the system must be checked
that they are attached properly to the terminal strips.
◊ Prior to operation, all screws in the water system
must be checked to ensure that they are in the
proper position and do not leak.
Initial Operation
Checks prior to operation:
◊ Prior to operation, the electrical connection values
and the data on the type plate must be checked for
consistency.
◊ You must ensure that all electrical connections have
been made in line with the requirements of the local
power supply company as well as national regula-
tions.
◊ The water lines must be clean and free of impuri-
ties . For this purpose, the lines should be rinsed out
twice or three times to ensure that all foreign matter
has been removed from the lines.
◊ Make sure that all shut-off valves in the cold water
lines are opened.
