4.8 Pump outlet connecon
WARNING:
Connect the pump outlet to a suitable treatment plant 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.
To connect the pump to your outlet accessories or to the exhaust treatment plant:
▪ Connect a 10 mm internal diameter vacuum hose or 12 mm internal diameter
plasc hose to the outlet nozzle (Figure: General view of the pump on page 11).
▪
Remove the outlet nozzle and connect to the 3/8 inch BSP tapped hole.
▪ Remove the outlet nozzle and replace it with an NW25 ange adaptor (available as
an oponal accessory, see Spares and accessories on page 36) and then connect to
the NW25 ange.
Take note of the following informaon before connecng to the pump outlet:
▪
The exhaust system must be congured 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.
▪ In the following circumstances, we recommend you to ng an oil mist lter to
the pump outlet
▪
if using the pump with the gas-ballast control open
▪
if operang the pump with an inlet pressure greater than 10 mbar for
extended periods or
▪
if frequently pumping down from atmospheric pressure.
▪
The mist lter will trap the oil exhausted from the pump: the oil can be re-used if it
is not contaminated.
4.9 Leak-test the system
Leak‑test the system and seal any leaks found aer you have installed the pump, to
prevent leakage of substances out of the system and leakage of air into the system.
