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
filtered 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, debris from entering the
container. Rinse container thoroughly and often. Do not
mix chemicals together that might react and cause a
precipitate. Use FILTERED fluid when filling container.
CLEAN SUCTION TUBE FILTER SCREEN
Inspect each time new solution is added. Clean filter
screen (#27) and suction tube (#25) as necessary by
rinsing in fresh water. Replace if necessary. Keep filter
screen off bottom of solution container to prevent dirt
and precipitate from clogging filter.
CLEAN INLET FILTER
Clean or replace inlet filter 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.
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.
