3.3 Connecting to the system
Before connecting the TRIVAC D 16 B Ex, remove the shipping seals from
the connection flanges (7/2 and 7/3).
We recommend that you retain the shipping seals in case you need to store
the pump in the future.
Connection port on the intake side - inside thread G 3/4“.
Connection port on the exhaust side - inside thread G 1“.
The inside threads (G 3/4” and G 1”) of the flame arresters on the intake and
the exhaust side must be sealed with Loctite 542 sealant when connecting
these to the system. Here the entire length of the thread of the flame arrest-
ers must be utilised for accepting the mating thread from side of the system.
Connect the intake and exhaust line using anti-vibration bellows, without
placing any strain on the pump.
The intake line must be clean and free of welding beads and scales. Deposits
in the intake line may outgas and adversely affect the vacuum. The connect-
ing flanges must be clean and undamaged.
Use suitable intake filters, respectively suitable accessories on the pump
