4 Operation
4.1 Media Compatibility
TRIVAC-B-DOT pumps can pump condensable gases and vapours, provided
that the gas ballast valve is open and the pump has attained its operating
temperature.
4.2 Start-up
TRIVAC-B-DOT pumps must only be operated in connection with brake
fluid filling and degassing systems.
Each time before starting up check the oil level. The pump must never be
operated with an oil level below the minimum.
Open all valves blocking the exhaust lines. The pump must never be
operated with a blocked or constricted exhaust line.
Do not select a degassing pressure of less than 1 mbar, since at this
pressure volatile substances in the brake fluid may escape and damage
the elastomer seals of the pump.
Check the direction of rotation before starting the pump for the first time and
after each change in the electrical connection (see Chapter 3.4).
On initial start-up, after prolonged idle periods or after an oil change, the
specified ultimate pressure cannot be attained until the oil is degassed.
This can be done by running the pump for approx. 30 min. with the intake
line closed and the gas ballast valve (7/5) open.
Use matching accessories only
Before starting the pump ensure that the pump and the fitted accessories
meet the requirements of your application and that safe operation can be
guaranteed.
Start up the pump only after it has been fully installed
Never operate the pump with an open intake port. Vacuum connections
as well as oil feed and discharge openings must not be opened while the
pump is operating. Avoid exposing any part of the human body to the
vacuum. There is the risk of suffering injury.
