NOTE
When the warm-up and cool-down modes are activated, an isolation valve (not included
in the scope of delivery of the vacuum pump) must be closed in order to allow the va-
cuum pump to operate at ultimate vacuum.
The isolation valve can be automatically controlled by the pump during the warm-up and
cool-down phases, see Optional Inlet Valve Control [►40].
In this case, the valve will open and close according to the diagram available in the
chapter Conveying Condensable Vapours [►39].
