Maintenance
Periodic Maintenance
Twice a month, flush a white vinegar solution (one
quart vinegar to two gallons of water) or anti-browning
solution (mixed as directed) through the machine. This
will prevent build-up of alkaline residue in the system.
Periodically inspect all hoses, electrical cables and
connections on your machine. Frayed or cracked hoses
should be repaired or replaced to eliminate vacuum or
solution pressure loss. The electrical cable must be
well insulated and cable connector screw kept tight. If
the cable insulation is broken or frayed, repair or
replace immediately. Don't take chances with electrical
fire or shock.
