Winterizing
For storage and transportation purposes in subfreezing
ambient temperatures, it will be necessary to winterize
the unit. The unit must be protected to the lowest
incurred temperature for the following reasons:
• If any part of the pumping system becomes frozen;
excessive pressure may build up in the unit which
could cause the unit to burst and result in possible
serious injury.
• The pumping system in this unit may be perma-
nently damaged if frozen. Freeze damage is not
covered by warranty.
If you must store the unit in an area where the tempera-
ture falls below 32° F (0° C), perform the following steps:
Gather the following items:
• Two 5 gallon containers.
• One gallon of antifreeze.
• Water supply.
• Three foot hose, 1/2-3/4 in. ID with a 3/4 in. male
garden hose fitting.
Procedure
1. To start winterizing, unit must be run and primed
(see Start-Up, page 13).
2. After running and priming, shut off unit and water
supply.
3. Relieve system pressure by pointing gun away from
yourself and anyone else and squeezing trigger until
water flow ceases to exit nozzle.
4. Engage trigger lock and remove nozzle.
5. In one 5 gallon container, mix antifreeze and water
according to manufacturer’s recommendations for
winterizing temperature.
NOTE: Proper winterizing is based on the recom-
mended manufacturer’s instructions listed on the
Protections Chart shown on the back label of most
antifreeze containers.
6. Remove water supply hose from unit and attach 3 ft
hose securely to inlet connection. Submerge other
end into antifreeze solution.
7. Shut off detergent injector if applicable.
8. Point wand into empty container and start unit.
9. Trigger gun until antifreeze begins to exit wand.
Release trigger for 3 seconds, then trigger gun for 3
seconds. Continue cycling gun several times until all
antifreeze mixture is siphoned from container.
10. Stop unit.
11. Detach 3 ft hose from unit and drain any excess
antifreeze back into 5 gallon container.
12. Disconnect hose/gun/wand assembly from unit and
drain any excess antifreeze back into 5 gallon con-
tainer.
13. Store hose, gun and wand with unit in a
non-freezing area.
14. Store antifreeze solution for next use or dispose
according to state EPA laws.
Optional Procedure
1. Shut off unit and water supply.
2. Relieve system pressure by pointing gun away from
yourself and anyone else and squeezing trigger until
water flow ceases to exit nozzle.
3. Disconnect and drain hose, gun and wand.
4. Start unit and allow it to run until all water exits from
unit. Once water has stopped flowing from unit, turn
unit off.
NOTICE
Do not store/operate unit in a freezing environment.
Damage to washer could occur.
NOTICE
When using this procedure, caution should be used
as ice chips can form from drops of water which could
cause the unit to burst. Allow unit to completely thaw
before starting.
