PERFORM DESCALING AS REQUIRED
Scale deposits on the interior of the heating system can cause a noticeable loss in
heating performance. Deposits of this kind result from hard water deposits, excessive
chemical use or improper chemicals. The frequency with which descaling procedures
are required will vary. If your area has particularly hard water or you see evidence of
deposits in the water system, you may have to descale monthly.
To descale your system:
1. Add an appropriate descaler chemical to your water box.
2.
Circulate it through the heating system. Let it stand.
3.
Flush and repeat as necessary.
4. Clean all screens and strainers, and check them frequently following descaling.
If you are circulating a descaler through the flowmeter, make sure to run clean
water through the flowmeter after you perform this procedure.
APPEARANCE MAINTENANCE
Maintaining the original appearance of your unit is important for two reasons:
1. It represents a big dollar investment for your cleaning business and its appearance
should reflect that fact. A dirty machine does not look professional.
2. Maintenance, troubleshooting and repair is much easier to accomplish on a clean,
well-maintained unit. Regular cleaning of the machine offers you an opportunity to
visually inspect all parts of the machine and spot potential problems before they
occur.
The following maintenance is recommended by the manufacturer at the frequency
indicated:
Daily
• Wipe machine down thoroughly with a damp cloth.
•
Flush recovery tank out thoroughly.
• Clean wand to maintain original appearance.
• Wipe down vacuum and high pressure hoses as needed.
• Visually inspect hoses for cuts, etc.
Weekly
• Wipe down entire unit as needed.
• Apply good coat of auto wax to all painted surfaces inside and out.
• Thoroughly clean wand and inspect for clogged jet, debris in vacuum slot and
leaking fittings at valve.
• Apply light coat of auto wax to wand. Thoroughly clean vacuum and high pressure
hoses including hose cuffs.
