MAINTENANCE-SEASONAL:
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.
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:
WARNING: RISK OF UNIT BURSTING. DO NOT STORE / OPERATE UNIT IN A FREEZING ENVIRONMENT!
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 follow-
ing one of the procedures listed below.
AIR BLOWOUT:
1. 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 inlet swivel or strainer fitting in the float tank.
3. Run compressed air into the system to remove all water from the system.
ANTIFREEZE SOLUTION:
1. Gather the following items:
a. Two 5 gallon containers.
b. One gallon of antifreeze. (Mi-T-M® recommends 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 and primed according to the "Start-up Procedures" listed on page 14.
b. After running and priming, 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 nozzle.
d. Lock the trigger gun in an OFF position and remove the nozzle.
e. In one 5 gallon container, mix the antifreeze and water according to manufacturer's
recommendations for the temperature to which you are winterizing.
NOTE: Proper winterizing is based on the recommended manufacturer'sinstructions
listed on the "Protection Chart" shown on the back label of most antifreeze con-
tainers.
f. Remove the water supply hose from the unit and attach the 3 foot hose securely to the
inlet connection. Submerge the other end into the antifreeze solution.
g. Point the wand into the empty container and start the unit.
h. Trigger the gun until the antifreeze begins to exit the wand. Release the trigger for 3 seconds, then trigger the
gun for 3 seconds. Continue cycling the gun several times until all the antifreeze mixture is siphoned from the
container.
i. Stop the unit.
j. Detach the 3 foot hose from the unit and drain any excess antifreeze back into the 5 gallon container.
k. Disconnect the hose/gun/wand assembly from the unit and drain any excess antifreeze back into the 5 gallon
container.
l. Store the hose, gun and wand with the unit in a safe, non-freezing area.
m. Store antifreeze solution for next use or dispose of according to state EPA laws.
