General requirements
Equip the system with an expansion vessel to damp pressure rise due to volume
changes when the temperature varies. Equip the system with a pump that provides
a nominal flow and pressure. Keep the pressure within the limits specified in Technical
data (page 120). Install a pressure regulator to make sure that the maximum permissible
operating pressure is not exceeded.
Install a bleed valve at the highest point of the cooling circuit, and a drain valve at the
lowest point.
The materials that can be used are listed in Cooling circuit materials (page 122).
Coolant temperature control
The temperature of the coolant in the internal cooling circuit must be kept within the
limits specified in Technical data (page 120). Note that the minimum temperature is
dependent on ambient temperature and relative humidity.
