3.8 Connect the pump outlet to the vacuum system
Connect the pump outlet port to the system exhaust line or to the system exhaust treatment plant using standard
fittings to connect to the relevant adaptor.
Take note of the following information before connecting to the pump outlet. Refer to Section 7.4 for details of the
accessories mentioned below.
The exhaust system must be configured so that the maximum pressure at the pump outlet does not exceed
0.5 bar gauge (1.5 bar absolute, 1.5 x 10
5
Pa) at full pump throughput.
3.9 Gas ballast inlet connection
The gas ballast can be supplied by either opening the gas ballast valve to atmosphere or connecting to an inert gas
supply.
The gas ballast is operated by the gas ballast control valve (Figures 1, 2, and 3, item 6). Adjust the gas ballast control
to regulate the flow rate of the gas ballast supply.
For more information about the use of gas ballast, refer to Sections 1.3, 2.2 and 4.1.
3.10 Leak test the system
Leak test the system after installing the pump. Seal any leaks found to prevent leakage of substances out of the
system and leakage of air into the system.
Connect the pump outlet to a suitable exhaust line to prevent the discharge of dangerous gases
and vapours to the surrounding atmosphere. Use a catchpot to prevent the drainage of
contaminated condensate back into the pump.
