SINGLE- CIRCUIT SYSTEM WITHOUT TANK
The cooling medium circuit is designed as a single-circuit system without tank. The pump conveys the
cooling medium inside the circuit through the evaporator and through the consumer.
The cooling medium in cooled inside the evaporator. The circuit consists of the following components:
pump of horizontal or vertical design,
piping system consisting of copper or plastic pipes with manometer and probe connection for the
operating thermostats and the digital temperature display.
If designed as a system closed to the atmosphere, the external circuit must be provided with
venting connections and with pressure compensation tank if required!

ALR – Composite Failure Report
The composite failure report summarizes all fault messages from the compressor, the pump(s), fan(s) of
the high-pressure and low-pressure pressostats, the flow monitor as well as the breakage of probes.
Voltage-free series connection of this composite report takes place at the terminals in the switch cabinet
(see circuit diagram in the Annex).
