Installation
3.3 Connection to the System
Before connecting the TRIVAC
®
T, remove the shipping seals from the con-
nection flanges (6/1) and (6/2).
Retain the shipping seals in case you need to store the pump in the future.
The pump is shipped with intake and exhaust flanges mounted for vertical con-
nection of the connecting lines. Connect the intake and exhaust lines with a
centering ring and a clamping ring each. Use the centering ring with dirt trap
for the intake port.
Connect the intake and exhaust line using anti-vibration bellows, without plac-
ing any strain on the pump.
The intake line must be clean. Deposits in the intake line may outgas and ad-
versely affect the vacuum. The connecting flanges must be clean and undam-
aged.
The maximum throughput of the pump is equivalent to the pumping speed of
the pump.
Note the specified cross sections for the connection lines
If exhaust gases must be collected or contained, do not allow the exhaust
line to become pressurized. The pressure in the oil box must not exceed
1.5 bar (absolute). An exhaust line which is too small in diameter or which
is blocked can result in the formation of overpressures within the pump.
Possible consequences can damage or even burst open pump. Thus the
exhaust line must be checked from time to time to ensure that there are
no obstructions. For avoiding of overpressure, you can install the exhaust
fan at the end of exhaust pipe or use the short wide exhaust pipe.
If no exhaust line is connected, it is advisable to fit an exhaust filter.
If several pumps are connected to one exhaust line, ensure an adequate
cross-section and a non-return valve at the exhaust of each pump.
Never operate the pump with a sealed exhaust line. There is the danger
of injury.
Avoid back flowing condensate
Install the exhaust line with a downward slope (lower than the pump) so
as to prevent condensate from flowing back into the pump. If this is not
possible, insert a condensate trap.
