Instruction of Flexible Conduits
A
Disassemble unions on the both sides of the flexible hose, and be aware
of the place of the washer.
B It is advised to connect the female union with explosion-proof equipment or
flameproof enclosure and pass through EYF/EYD, nipple is necessarily to be
used for relevant matching when needed, and EYF/EYD also needs to be used
for relevant wiring on the commissure of male union and distributor box.
C Connect Internal threads part of union of flexible hose with EYF/EYD, and then
connect to machine or electric device, connect external threads with flexible
hose via cap nut part, and be aware of the location of the washer, bear in mind
to tighten external threads part until the flexible hose and Internal threads are
unable to turn themselves.
D External threads part of the flexible hose also has to be connected with
EYF/EYD before connecting with the flameproof enclosure; likewise, be aware
of the place of the washer when connecting with flexible hose, and it also needs
to be tighten until external threads and flexible hose are both unable to turn
themselves.
E Details about assembling methods of EYF/EYD and union please re fer to the
instruction of relevant items.
