XI. Wet Separator
The Wet Separator will be supplied for wet material pickup and
water flushing. This separator will have a ball float shutoff, a
float switch flange, and a 1 1/2” FPT pump connection. The
standard float switch flange is for pump operation, and when an
overflow control is required a special float switch flange will
have to be added above the standard one. When a pumping
arrangement is not required the 1 1/2” FPT pump connection
will be plugged and the float switch flange will be capped.
To insure proper operation of the separator check all connections
and inspection doors to be sure they are properly sealed and
do not leak air into the system.
The separator should not be allowed to become so full that the
accumulated material interferes with its efficiency.
After each cleaning period the separator should be cleaned
according to the following procedure:
1. Shut down the Vacuum Producer.
2. Pour required disinfectants into funnel.
3. Open lower water tap, so slurry of dirt in solution will form.
4. Open upper water tap to aid in filling separator.
5. Close upper water tap after approximately:
1 minute for 24” separator
2 minutes for 30” separator
3 minutes for 36” separator
6. With lower water tap open to continue whirlpool action of
solution, open discharge valve to sewer, to flush out
separator.
7. Proceed with flushing action until discharge water becomes
clean.
8. Close lower water tap and let separator drain-out.
9. Close discharge valve to sewer.
10. System can now be used for vacuuming.
XII. Portable Wet
Separator
The separator is used for picking up wet solutions and is not
intended for general cleaning.
It is connected to the system by the use of a short length of
hose. The male end of the hose is plugged into an inlet valve of
the main system. The female end of the hose is attached to the
1 1/2” hose coupling at the top of the separator.
The separator should be drained and flushed after each use. It
is flushed by removing the cover assembly and pouring in clean
water while the faucet on the separator is open and draining.
