DD & BB Series
Optional Flow Totalizer
The flow totalizer (optional) is a resettable
counter for accumulating the water flow and is
equipped with a 10 year battery to retain
memory. The meter will accumulate flow even if
injection is turned off.
The PRIME ON/OFF Switch
This button (see photo above) allows you to turn
off the injection of chemical, but still record the
flow if you have the optional counter/totalizer.
●
To turn the injection OFF , press
the button. Injection will stop.
●
To
turn the injection ON , press the
button. The valve light will flash and the
injector will make the first pumping
stroke.
●
When priming the injector , you can
make repetitive pumping strokes by
pressing the PRIME ON/OFF switch
OFF and ON. Be sure to leave the unit
on after priming.
NOTE: Priming is quicker and easier at a dial
setting of 10.
You must have at least 30 psi of
back pressure in order for the
system to operate correctly.
Setting the Pumper
At a dial setting of 10, the feed ratio will be that
shown on the control panel. (See Photo 1.) That
is the maximum feed for your unit. If you wish to
feed less, the feed dial may be set to a lower
setting.
Example: If your injector chemical : water feed
ratio at 10 is 1:200, at a setting of 5 it will feed
half as much, which corresponds to a
chemical
: water feed ratio of 1:400.
Once your injector is set, it is fully operational.
Maintenance & Storage
Servicing the Pumper
Your injector normally requires very little
maintenance.
For servicing and calibrating your pumper and
chemical valves, refer to the separate pumper
and pumper calibration manuals supplied with
your unit. For pilot valve problems refer to the
separate pilot valve manual. If you are unable to
locate them, they are all available on our
website at
http://heanderson.com/manuals.php .
Storage
Warning! Your injector can be
damaged if allowed to freeze.
Freeze damage is not covered
under warranty.
You should take the necessary precautions to
protect the injector from freezing.
●
If you remove your injector from the line
for the winter, you should drain the
water from it.
●
You should also remove the pumper
from the pilot valve and drain the water
from it.
