ANTIFREEZE PROCEDURE (cont.)
5. Remove the garden hose inlet fitting from the end of your garden hose
and plug it into the front of the machine. Leave it plugged in until the
next time the machine is used.
With the hoses and wand connected, run the machine and spray the
water/antifreeze solution out of the wand until the ‘low water’ switch in
the water box shuts the pump clutch off. Your machine is now freeze-
protected.
SOLUTION HOSE AND WAND FREEZE GUARD PROCEDURE (OPTIONAL):
6. Attach the solution hoses and wand to the machine. (Dependent upon the
amount of hose attached, more antifreeze solution may be needed in the
water box. With the machine running, spray the wand into a container to
recapture the antifreeze solution. Continue to spray the wand until the
pump clutch shuts off.
Recovering Antifreeze for Re-Use :
Open the water box drain valve and allow the antifreeze solution to drain
into a sealable container so that it may be used again.
Before cleaning with the machine again, flush the remaining antifreeze
solution from the system by spraying water through the hoses and wand
until all signs of antifreeze are gone.
One manufacturer of antifreeze cautions:
“WHEN DISPOSING OF USED ANTIFREEZE COOLANT: Follow local laws and
regulations. If required, dispose at facilities licensed to accept household hazardous
waste. If permitted, dispose in sanitary sewer systems. Do not discard into storm
sewers, septic systems, or onto the ground.”
