MAINTENANCE:
RINSE INJECTOR AFTER EACH USE:
additive allowed to remain in injector can dry out and foul or damage lower end at the next
start up. Put suction tube into a 1 qt. (4 liters) or more container of fresh filtered water. Pull fresh
water through the injector by operating until container is empty. This procedure is not needed for
continuous operation.
BYPASS INJECTOR: When not in use put the injector in bypass mode by using the three valve
bypass (preferred) or the On/Off lever on the injector. See Fig.4 Pg.8.
CLEAN SUCTION TUBE FILTER SCREEN: Inspect each time new solution is added. Clean
as frequently as necessary by washing in fresh water. Remove filter screen (#27) from suction tube
(#25) and run water backwards through it. Replace if necessary. Keep filter screen off bottom of
solution container to prevent dirt and precipitate from contaminating solution.
STORAGE: For extended storage, rinse injector as described above and place entire injector
underwater (in 5 gal container). Monthly, apply a small amount (thimble full) of chlorine bleach to
avoid algae growth.
CLEAN SOLUTION CONTAINER: Keep covered to prevent any contaminants from entering
container. Rinse container thoroughly and often. Do not mix chemicals together that might react
and cause a precipitate. Use FILTERED WATER when filling container.
CLEAN INLET FILTER: Clean or replace inlet filter as required to increase the life of the unit
as well as reduce pressure loss.
REPLACE DOSAGE PISTON AND SHAFT SEAL: The injector is shipped with a spare Dos-
age Piston (44) and shaft seal (17), see Fig. 1, as these are normal wear parts, replace both when
solution injection is less than set amount.
