Installation Instructions
The union assembly package includes a male adapter, female flange, threaded collar, 2 set screws, and an allen wrench.
- Thread the process thread of the male adapter into the enclosure or machine threads.
- Pass the conductors through the enclosure or machine and union assembly.
- Place the female flange onto the end of the male adapter, aligning the serrated flamepaths, and thread the collar onto the male adapter by hand. The male adapter and the female flange will be held together by the threaded collar. Lightly wrench tighten the threaded collar.
- Using the allen wrench, tighten at least one of the set screws to lock the threaded collar in position.
- Add an enclosure or other conduit fitting by threading into the threads of the female flange.
Schedule of Limitations
- The union, when used in flameproof applications, must not be closed with a flameproof stopping plug.
- The ‘male adapter’ has the option of two parallel process thread options (metric and UNF) which have a 3.5 mm (maximum) undercut at the base of the entry thread, and therefore must only be fitted into a flameproof enclosure with entries having a minimum of 14mm full thread form measured from the external surface.
- As an alternative to the previous limitation, the flameproof gland must be fitted with a non-detachable, noncompressible washer having a minimum thickness of 2mm between the head of the gland and enclosure.
- When process or connection threads are of parallel thread form, additional measure must be taken to seal the threads in order to maintain the union’s IP65 rating.
