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.
1. Gather the following items:
a. Two 5 gallon containers.

of most antifreeze containers.
b. To start winterizing, unit must be run according to the "Start-Up/Cold
Water Operation" listed on pg. 14.
c. After running, shut off the unit and water supply.
d. Relieve system pressure by pointing the trigger gun in a safe

j. Stop the unit.
k. Disconnect the hose and trigger gun from the unit and drain any
excess antifreeze back into the 5 gallon container.
l. Drain hose, trigger gun and lance assembly and store with the unit
in a safe non-freezing area.
m. Store antifreeze solution for next use or dispose of according to state
EPA laws.
OPTIONAL PROCEDURE:
a. Shut off the unit and water supply.
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, trigger gun and lance assembly.
d. Remove the coil drain plug from the heat exchanger inlet.
e. 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 unit off.
NOTE: When using this procedure, use caution as ice chips can form from
drops of water which could cause the unit to burst if starting before
completely thawed.
