6.7.2 49B49BMonitoring the end temperature
A suitable measuring instrument must be installed that switches
the VacuStar WR off when the maximum permissible temperature
is reached.
Assembly
1. Install the temperature sensor in the line after the pressure
pipe joint.
2. Connect the temperature sensor to the superordinate vehicle
controller.
CAUTION!
– The temperature sensor connection must be
intrinsically unbreakable.
– The maximum shutdown temperature is 95 °C
6.7.3 Non-return valve
When a vacuum is applied and the VacuStar WR is stopped, the
non-return valve prevents the air and the process water from
flowing back into the suction line.
The non-return valve must be installed immediately before the
suction flange.
6.7.4 Vacuum suction filter
An adequate filter (filter mesh < 0.5 mm) is required to prevent
solid matters from being sucked in.
Assembly
Install the vacuum filter into the suction line upstream from the
VacuStar WR. Observe the flow direction.
CAUTION!
For explosion-proof VacuStar WR, use only filters
that are resistant to the explosion pressure shock.
Such filters can be purchased from CVS for the
VacuStar WR 2500 and WR 3100.
6.7.5 Protection against contact
Rotating or hot parts of the system must be equipped with a
protection against contact.
Please note that the German accident prevention regulations do
not allow a maximum surface temperature of 80 °C to be
exceeded.
