FREEZE PROTECTION
Freeze protection of the machine is necessary to
prevent damage to components of the solution
system if the machine is going to be exposed to
freezing temperatures.
ATTENTION: Freezing temperatures can severely
damage components. Do not store or transport
machine in areas where freezing of solution
contents could occur, unless machine is freeze
protected. Failure of components due to lack of
freeze protection voids the warranty on such
components.
To protect machine from freezing:
1. Move machine over floor drain and plug the
power cord into an outlet. Drain both tanks.
2. Pour 2 L (0.53 gal) of pre-mixed
automotive-type windshield washer solution into
solution tank.
ATTENTION: Do not use cooling system
anti-freeze such as ethylene glycol.
3. Press the bottom (l) of the hand tool switch. The
pump will start and spray through the nozzles to
the floor. Run the pump until all solution has
been dispensed through system.
ATTENTION: Machines and attachments that have
been freeze protected must be flushed
completely prior to normal use. Follow directions
for the appropriate cleaning process, but run
your selected cleaning solution through the
system to purge all anti-freeze before starting the
cleaning process.
