IMPORTANT NOTE
Damage to the K°Bloc due to sudden temperature changes
and temperature differences!
Sudden temperature changes and major temperature differences of the flow
media may damage the inside of the K°Bloc.
 Bring the K°Bloc to the operating temperatures of the two circuits by
means of the flow media at low pressure.
 Avoid quick temperature changes (maximum temperature change: 5
K/min.).
 Respect the maximum temperature difference of the flow media of 200 K
max. between the hot and the cold side.
 Ensure that under all setting-up and operating conditions, the tempera-
ture never falls below the freezing temperature of the flow media used.
IMPORTANT NOTE
Damage to piping connections and to K°Bloc due to exces-
sive pressure variations, forces and torques!
When excessive forces and torques are transmitted on the K°Bloc connec-
tions through the piping, the piping connections and/or the K°Bloc may be
damaged.
 You can take the forces and torques permitted for your K°Bloc from the
technical documentation.
 Ensure that the forces and torques transmitted from the piping to the
K°Bloc connections are not too high.
 Always open or close the valves of the piping connected to the K°Bloc
slowly.
 Avoid sudden evaporation and condensation of gases by suitable
process control.
 Respect pressure variations of max. 2 bar/min. (1.4404/316L) and
0.5 bar/min. for other materials.
