FROST PROTECTION SENSORS
COMPONENT DESCRIPTION
Control unit (RC1)
The control unit is located in the control cabinet. See descrip-
tion on Page 9.
Control circuit fuse
Reset the automatic fuse by pulling the green control upwards.
Main circuit breaker
The main circuit breaker is used to switch the cooling unit off
and on. When performing work on the cooling unit, always
open and lock the main circuit breaker. Certain terminal blocks
can be live even when the circuit breaker is switched off, such
as the terminal blocks for outgoing summation alarms.
Important!
The setting of the frost protection sensors
must not be altered. This could lead to
frost bursting the exchangers. Burst pipes
due to frost will result in major leakage of
fluid and risk of compressor damage.
The control circuit fuse does NOT cut
the power to the entire cooling unit.
When performing work on the cooling
unit, always open and lock the main
circuit breaker.
