•
Always use a defoamer when foaming occurs to prevent vacuum motor damage.
•
Never use water above 130
°
F (54
°
C).
•
Do not use outdoors or where temperature is below freezing. Protect your machine
from any extremes in temperatures.
•
Do not let the pump run dry. Turn the pump off and refill the tank when cleaning solution
gets low.
•
Flush the machine with an acid de-scaler regularly (monthly or more often) to prevent
a build-up of minerals or chemicals in the pump and heat systems. Follow the flush
with a clear water rinse to remove any particles and to rinse the acid from the machine.
•
Use approved chemicals only. All chemicals should be mixed thoroughly. Liquid
chemicals are recommended to prevent powder buildups. A pH between 6 and 9 is
recommended. The use of high alkaline detergents or strong acids will accelerate the
wear of the pump and seals, and will void the warranty.
•
All extension cords must have a rating of at least 12/3 (#12 cord). Extension cords
should be no longer than 50 feet. Replace the plug immediately if the ground prong
becomes damaged or is broken off.
