Winter Storage
Prepare the sprayer for end
-
of
-
season storage by running RV antifreeze through the system. This will keep internal parts
lubricated, protect against corrosion and keep the unit from freezing.
Note: RV antifreeze is non
-
toxic and biodegradable
and generally safer for the environment than automotive antifreeze.
Before storing your sprayer for winter or long term storage, thoroughly clean and drain it as much as possible. Then pour
enough pink RV antifreeze into the tank so that when the pump is turned on you can pump the antifreeze throughout the
entire plumbing system, including the pressure adjust (bypass) line. Make sure to operate the boom and handgun until
you see pink fluid spraying from the nozzles. Leave any remaining antifreeze in the tank. Before your next usage, rinse
the antifreeze from the sprayer with clean water.
It is nearly impossible to drain all of the water from the sprayer and any trapped water can freeze in cold weather and
damage parts of the sprayer. Pumping the antifreeze through the system will displace the water and help prevent this
damage.
DO
•
Clean and rinse your pump after each use with Fimco Tank
Neutralizer
•
Winterize your pump or sprayer by rinsing, draining and
running RV Antifreeze through it before storing for the winter.
•
Use clean water for your spray mixture
•
Store inside a building when not in use.
DON
’
T
•
Use to pump bleach.
•
Use to pump petroleum products such as diesel fuel, gaso-
line or kerosene.
•
Leave your pump sit with spray mixture in it for extended
periods.
•
Use dirty or unfiltered water for spraying.
