Kit shown on a
single injector.
RINSE INJECTOR AFTER EACH USE
Additive allowed to remain in injector can dry, foul or
damage the lower end at the next start-up. Place suction
tube into a 1 qt. (0.95 liters) or more container of fresh
 ltered water. Flow fresh water through the injector by
operating until container is empty. This procedure is not
needed for continuous operation.
CLEAN SOLUTION CONTAINER
Keep covered to prevent dirt,  ies, feathers and other
 ying debris from entering the container. Rinse container
thoroughly and often. Do not mix chemicals together that
might react and cause a precipitate. Use FILTERED  uid
when  lling container.
CLEAN SUCTION TUBE FILTER SCREEN
Inspect each time new solution is added. Clean  lter screen
(#27) and suction tube (#25) as necessary by rinsing in
fresh water. Replace if necessary. Keep  lter screen off
bottom of solution container to prevent dirt and precipitate
from clogging  lter.
CLEAN INLET FILTER
Clean or replace inlet  lter as required to increase the life of
the unit as well as reduce pressure loss.
BYPASS INJECTOR
When not in use place the injector in bypass mode by using
the three valve bypass (preferred) or turn the
on/off lever on the top of the injector to the off position.
STORAGE
For extended storage, rinse injector (see "Rinse Injector
After Each Use") and place underwater in a container. Apply
monthly, <0.1 oz. (29 ml) of chlorine bleach to avoid algae
growth. KEEP FROM FREEZING.

Remote Injecting

Remote Injector Kit (not included)
Is recommended for the following:
Single Injector:
To prevent mineral buildup within the body of the unit. Use when
injecting chemicals that cause minerals to precipitate from  uid
(see Fig. 5)
Injectors In a Series:
When injecting multiple chemical injections, using two or more
injectors. Each injector adds chemical to the  uid(water) system,
while bypassing the next injector and eliminating the potential
damage to that injector (see Fig. 6).
