1. For storage and transportation purposes in subfreezing ambient temperatures,
it will be necessary to winterize this unit. This unit must be protected to the

a. 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.
b. 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.

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.
STARTING UNIT AFTER EXTENDED STORAGE:
1. BE CERTAIN the unit is NOT plugged into the power source.
2. Prior to restarting the unit, thaw out any possible ice from the wand, gun, hose
