Installation
Double check the direction of
water flow when you install your
injector.
The model DD has 1-1/4" NPT pipe connections.
The model DB has 1" NPT pipe connections.
You can adapt to other pipe sizes if needed We
recommend that the injector be installed in a
bypass to allow you to service it if the need
arises.
The check valve(s) have a yellow
arrow stamped on them. These
arrows must point up when
installed.
Refer to the the typical installation drawing
(Page 4) and parts breakdown for your model
for proper installation of chemical check valves
and tubing.
●
Install the valve module or chemical
check valves on the plastic pumphead.
●
The foot valve or priming stick goes into
the chemical tank.
●
Connect a length of plastic tubing from
the chemical tank to the lower hose barb
or the lower check valve.
●
Connect a short piece of tubing from the
discharge valve or upper hose barb to
the injection point fitting (IPF).
●
C o n n e c t t h e 3 / 4 " r e d h o s e t o
t h e hose barb on the bottom of the pilot
valve. There will be waste water emitted
from this hose during the pumping cycle.
The volume discharged will be
approximately three times that of
chemical pumped. Th e wa te r th at is
em itt e d is cle a r, untreated water.
This hose must vent to atmosphere
and cannot be elevated or restricted.
Initial System Check
Use a power surge protector to
help prevent electrical surges
from damaging the unit. Power
surges, lightning, and other
“acts of God” are not covered under the
warranty.
The injector uses 12VDC power
to operate. Do not run 120VAC
directly into the unit. Always,
use the supplied transformer
when possible. Once you have applied
power, we are ready for the initial system
check.
●
Apply power to your injector.
●
Watch the lighted indicators located in
the cover.
●
The power light(red) should be on
constantly.
●
The flow light(yellow) should flash when
there is water flowing.
●
The cycle light(green) flashes when the
injector makes a pumping cycle
(depending on the volume of water flow,
it may take several seconds for this light
to flash).
●
If the lights are not operating correctly,
immediately unplug the unit and call
your distributor or H.E. Anderson Co. to
report the problem.
