STORAGE & MAINTENANCE INSTRUCTIONS
WINTERIZING:
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 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.
1. 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 16.
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 Dual Lance Assy.
d. Lock the trigger gun in the OFF position and adjust the Dual Lance to the low
pressure mode.
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.
DIRECT FEED MODELS:
1. Remove the water supply hose from the unit and attach the 3 foot hose
securely to the inlet connection.
2. Shut off the detergent injector (if applicable).
3. Fill one 5 gallon container with water.
4. 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.
5. Start the unit. Trigger the gun several times until all the air is worked out
of the system (unit is primed).
6. 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.
7. Point the trigger gun into the empty container. (Be certain to wear safety
attire for protection from splashing.)
8. 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.
9. Stop the unit.
10. Detach the 3 foot hose from the unit and drain any excess antifreeze back
into the 5 gallon container.
