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.
If spray jets become clogged, remove the spray tips,
wash them thoroughly, and blow dry.
NOTE: Do not use pins, wires, etc. to clean nozzles
as this could destroy the spray pattern.
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
elctrical fire or shock.
Daily/Regular Maintenance
Before making any repairs or adjustments to the
machine, disconnect the power cords from the
electrical source.
1. Empty unused cleaning solution from the solution
tank.
2. Inspect and clean filter screen in solution tank.
3. Flush pumping system with 1 to 2 gallons of clean
water.
4. After each use, rinse tank with fresh water. Period-
ically inspect the recovery tank and decontaminate
if necessary, using a Hospital Grade Virucide or a
10-1 bleach to water solution. Waste water should
be disposed of properly.
Do not allow machine to freeze.
