A higher flow rate will not improve the performance of the leak detector + backing
pump assembly.
5.8.2 Connection of the backing pump
The leak detector must be connected to a backing pump before being switched on.
2 DN 25 ISO-KF connections are available to connect the backing pump.
●
1 connection at the rear (configuration on delivery)
●
1 connection under the frame
A Connection at the rear 1 DN 25 ISO-KF connection tubing
DN 25 ISO-KF plastic blanking plate (supplied with the detector)
B Connection underneath 2 Filler cap
Backing pump connection under the frame
NOTICE
Using an external backing pump
It is the user's responsibility to protect the detector from any contamination or deterioration that may
be caused by the connected external backing pump (particles, backscattering of oil in the detector,
for example).
►
