3.O1 General Maintenance Tips & Schedule

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, and other 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 and suction tube 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 using a minimum of 1/2 
gallon. (See “Rinse Injector After Each Use”) Drain water 
from unit. Inspect lower end seals. Apply thin coat of silicone 
to seals and reassemble unit. Place plugs back into inlet/
outlet & suction tube fitting. KEEP FROM FREEZING.

Perform these maintenance 
procedures to extend the life of your unit.
