3.7.2 Discharge line thermostat
YF*K1E compressors have no internal discharge gas temperature protection. Therefore, an external
discharge line thermostat must be installed.

– Technical data
To ensure proper functioning and to avoid f alse readings, the discharge line thermostat must be
installed and insulated according to the procedure and recommendations hereunder.
Assembly of the discharge line thermostat
▪
Install the discharge line thermostat on the
discharge tube 120 mm from top cap.
▪
Snap the retainer clip over the tube and onto
the thermostat.
▪
The thermostat should be placed on the
discharge tube so that its body is in upward
position on a horizontal tube installation.
▪
Ensure that the thermostat is not tilted.
▪
The wire must not be in contact with the top
cap of the compressor or the discharge tube.
Care should be taken to route wires so that
they do not come into contact with sharp
objects.
▪
To avoid any impact on tripping temperature
by the ambient, the discharge line thermostat
must be insulated.
▪
Wrap thermal insulation around the pipe left
and right of the thermostat and secure it with
plastic straps.
▪
Wrap a second layer of insulation around the
first one and around the thermostat and
secure it with plastic straps.
