General requirements
Equip the system with an expansion tank to damp pressure rise due to volume changes
when the temperature varies. Keep the pressure within the limits specified in
below. Install a pressure regulator to ensure that the maximum permissible
operating pressure is not exceeded.
Install a bleed valve at the highest point of the cooling circuit. Install a drain valve below
the lowest pipe in the cooling circuit.
The materials used in the cooling system are listed in
