maintenance instructions

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:
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.
. 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, 1/2-3/4 I.D. with a 3/4 inch male garden hose fitting.
2. Procedure:
a. To start winterizing, unit must be run according to the "Start-up Cold
Water Operation" listed on page 2.
b. After running, 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
lance assembly.
d. Lock the trigger gun in the OFF position.
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.
e. Remove the water supply hose from the unit and attach the 3 foot
hose securely to the inlet connection.
f. Shut off the detergent injector (if applicable).
g. Fill one 5 gallon container with water.
h. Holding the 3 foot hose in an upright position, completely fill the hose
with water. Then plug the open end of the hose with your thumb or
finger. Place the plugged end into the 5 gallon container of water.
i. Start the unit. Trigger the gun several times until all the air is worked
out of the system (unit is primed).
j. With the trigger gun held open, siphon enough water out of the 5
gallon container until there is just enough water left to mix with the
antifreeze.
k. Point the trigger gun into the empty container. (Be certain to wear
safety attire for protection from splashing.)
l. Trigger the gun until the antifreeze begins to exit the trigger gun.
Release the trigger for 3 seconds, then trigger the gun for 3 seconds.
Continue cycling the trigger gun several times until all the antifreeze
mixture is siphoned from the container.
m. Stop the unit.
n. Detach the 3 foot hose from the unit and drain any excess antifreeze
back into the 5 gallon container.

AIR BLOW OUT:

. Remove the nozzle from the wand assembly. Squeeze the trigger
until water ceases to exit the wand assembly.
2. Connect an air fitting from an air hose to the unit's inlet.
3. Run compressed air into the system to remove all water from the
system.
