STORAGE & MAINTENANCE

WINTERIZING:

For storage and transportation purposes in subfreezing ambient temperatures,
it will be necessary to winterize this unit. This unit must be protected to the
lowest incurred temperature for the following reasons:
1. If any part of the pumping system becomes frozen; excessive pressure
may build up in the unit which could cause the unit to burst resulting in
possible serious injury to the operator or bystanders.
2. The pumping system in this unit may be permanently damaged if frozen.
FREEZE DAMAGE IS NOT COVERED BY WARRANTY.
If you must store your unit in an area where the temperature may fall below
32°F, you can protect your unit by following the procedure outlined below.
. Gather the following items:
a. Two 5 gallon containers.
b. One gallon of antifreeze. (Use an environmentally safe
antifreeze.)
c. Water supply.
d. Three foot hose, /2-3/4 I.D. with a 3/4 inch male garden hose
fitting.
2. Procedure:
a. To start winterizing, unit must be run and primed according to the
"Start-up" listed on page 6.
b. After running and priming, shut off the unit and water supply.
c. Relieve system pressure by pointing the trigger gun in a safe
direction and squeezing the trigger until water flow ceases to exit
the nozzle.
d. Lock the trigger gun in an OFF position and remove the nozzle.
e. In one 5 gallon container, mix the antifreeze and water according to
manufacturer's recommendations for the temperature to which you
are winterizing.
NOTE: Proper winterizing is based on the recommended manufacturer's
instructions listed on the "Protection Chart" shown on the back label
of most antifreeze containers.
f. Remove the water supply hose from the unit and attach the 3 foot
hose securely to the inlet connection. Submerge the other end into
the antifreeze solution.
g. Shut off the detergent injector if applicable.
h. Point the wand into the empty container and start the unit.
i. Trigger the gun until the antifreeze begins to exit the wand. Release
the trigger for 3 seconds, then trigger the gun for 3 seconds. Continue
cycling the gun several times until all the antifreeze mixture is
siphoned from the container.
j. Stop the unit.
k. Detach the 3 foot hose from the unit and drain any excess antifreeze
back into the 5 gallon container.
l. Disconnect the hose/gun/wand assembly from the unit and drain
any excess antifreeze back into the 5 gallon container.
m. Store the hose, gun and wand with the unit in a safe, non-freezing
area.
n. Store antifreeze solution for next use or dispose of according to state
EPA laws.
3. Optional Procedure:
a. Shut the unit and water supply off.
b. Relieve system pressure by pointing the trigger gun in a safe
direction and squeezing the trigger until water flow ceases to exit
the nozzle.
c. Disconnect and drain the hose, gun and wand.
d. Start the unit and allow it to run until all the water exits the unit. Once
the water has stopped flowing from the unit, turn the unit off.
NOTE: When using this procedure, caution should be used as ice chips
can form from drops of water which could cause the unit to burst if
starting before completely thawed.
