Winterizing - Mi-T-M Corporation CHV Serie Manual Del Operador

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:
. 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.
. 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 suction hose with a  /2 inch cam and groove adapter
(Mi-T-M #5-022).
2. Procedure:
a. Shut off the unit and water supply.
b. In a 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 manufacture's
instructions listed on the "Protection Chart" shown on the back
label of most antifreeze containers.
c. Remove the water supply hose from the unit and attach the 3 foot
hose securely to the inlet connection. Submerge the opposite end
into the antifreeze solution.
d. Point the wand into the empty container in cone mist mode.
e. Trigger the gun and start the unit. Continue until all the antifreeze
mixture is siphoned from the container.
f. Detach the 3 foot hose from the unit and drain any excess antifreeze
back into the 5 gallon container.
g. Disconnect the hose/gun/wand assembly from the unit and drain any
excess antifreeze back into the 5 gallon container.
h. Store the hose, gun and wand with the unit in a safe area.
i. Store antifreeze solution for next use or dispose of according to state
EPA laws.
3. Optional Procedure:
a. Shut off the unit and disconnect the pump inlet water supply hose.
b. Point the trigger gun in a safe direction and squeeze the trigger until
water flow ceases to exit the nozzle.
c. Disconnect and drain the hose, gun and wand.
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.
