PROTECT FROM FREEZING - Caution!
If it becomes necessary to store in temperatures that could drop below 40
degrees F, the pumping system, hoses and valves must be protected from
freezing with a methyl hydrate window washer antifreeze solution. Do not use
ethylene glycol or cooling system antifreezes.
Whenever unit will be stored in temperatures below 40 degrees F, empty the
solution tank, and then pour a half-gallon of pre-mixed window washer antifreeze
into the tank. The windshield washer fluid must not be diluted with water or
solution already in the tank. Turn on the brush switch and press the spray switch
until the unit runs completely dry.
Before returning the unit back to service, allow it to reach room temperature first.
Then add a half-gallon of plain water to the solution tank and flush the system
using the spray switch.
The unit has been tested at the factory with windshield washer antifreeze
solution. A small amount of this solution may remain in the system and must be
flushed out prior to first use.
