Attach the Coupling Body to the
Vacuum Pump
The supplied coupling body must be attached to your vacuum pump. Remove
the plug from the oil drain port on your vacuum pump. Allow oil that is in the
pump to drain into a suitable container.
Wrap two turns of the supplied PTFE tape around the threads of the coupling
body. Thread the coupling body into the vacuum pump drain hole. Tighten
securely. Note that the coupling body is supplied with a male 1/4 NPT
connector to attach to vacuum pumps sold by Labconco Corporation. If your
vacuum pump has a drain port that is not compatible with this size connector,
you will need to supply a suitable adapter (see Appendix D: Accessories for
some adaptors).
Position the vacuum pump where it will be used and attach the vacuum hose
which connects the vacuum pump to your equipment.
