- Use inert gas for gas ballast to avoid the formation of
explosive mixtures. A special adapter fitting is needed
to connect an inert gas supply line (see “Accessories
/ Spare parts”, pg. 93). This adapter replaces the
standard gas ballast cap and allows for an inert gas
line to be connected via a KF DN 16 small flange at a
maximum supply pressure of 17.5 psi (1.2 bar) abso-
lute.
- Close the gas ballast valve by turning the cap 180°.
In case of low boiling solvents (when the formation of
condensate is unlikely), the use of gas ballast might be
unnecessary. Operating the pump without gas ballast in-
creases the solvent recovery rate at the exhaust waste
vapor condenser.
In case of condensation
In case of condensation : Check the liquid lev-
el in the catchpots during operation. Check the
liquid level in both catchpots regularly. Do not
allow the catchpots to overfill. Drain catchpots
in time to avoid overflow. Install a level sensor
(see “Accessories / Spare parts”, pg. 93) for
monitoring, if necessary.
The maximum liquid level is at approximately
80% of the total filling level to avoid problems
when removing the catchpots.

✔
Removing the catchpots:
Catchpot at outlet:
Remove joint clip. Remove catchpot and drain
condensate.
Catchpot at inlet:
Admit air or inert gas (via the pump inlet) to
restore atmospheric pressure in the catchpot
before attempting removal. Remove joint clip.
Remove catchpot and drain condensate.
