SET UP INSTRUCTION
Filter Installation
There are three filters in the Pro 500/750: inlet filter, main filter and pump protection filter. It is
imperative to the efficient operation of the Pro 500/750 that the filters are installed properly.
Pump Protection Filter – Position on brass fitting on the filter mound. Slide it down.
Main Filter – Wet the rim of the filter and position it on the filter mound. (white plastic disc) Twist
and slide over the mound by pushing downward.
Inlet Filter – Position on top of the tank.
OPERATING INSTRUCTIONS
1. Remove lid and inlet filter.
2. Check main filter. Make sure the main filter is installed snugly.
3. Fill tank with water to a desired level. Use solution level gauge. Maximum water temperature
to be used is 130oF (54o C).
4. Add in-tank cleaner per chemical label use instructions. In addition, pre-spraying is often
desirable and will assist in producing the fastest and best cleaning results. See chemical product
labels for more information.
Note: Use caution when moving machine (especially on inclines) with fluid in the tank to prevent
fluid from entering vacuum standpipe at back of machine tank and flooding the vacuum.
The user MUST ONLY use chemicals that have been speically formulated to work with CFR
technology machines.
5. Prime pump by re-circulating fluid through priming hose, included, for 15-30 seconds. Re-
circulating the fluid primes the pump and expels trapped air from the system.
6. Replace inlet filter and lid
7. Attach hose assembly to machine. Connect fluid hose to the quick-disconnect found on the
front of machine.
8. Attach the desired tool to the valve end of the hose assembly.
9. Close tank cover lid, turn on vacuum and pump switches.
10. Clean surface with tool attached to hose assembly.
11. During the cleaning process, the fluid level will be reduced and the lower level float switch will
shut off the pump. When the pump shuts off, drain and rinse tank, rinse main filter, refill with fresh
water and cleaning chemical, and continue cleaning.
CAUTION! When cleaning, monitor foam in the machine’s tank. Areas cleaned with other
cleaning equipment or chemicals may cause excessive foam to collect in the tank.
WARNING! EXCESSIVE FOAM IN THE TANK MAY CAUSE VACUUM MOTOR FLOODING AND
MACHINE DAMAGE.
Pour one to two ounces of Defoam directly into the tank or into the vacuum hose while the
vacuum is running. Defoam has been speically formulated to work with this machine.
When finished cleaning, perform the daily maintenance procedure. Be sure that all filters are
cleaned thoroughly and replaced in machine. Leave lid off for drying.

9
Perfect Heat System
WARNING! The Perfect HeatTM Plus System can produce very hot water that could damage
some delicate fabrics and fibers. Please ensure the surface being cleaned will not be
damaged by applying hot water up to 200oF (93o C).
This machine is equiped with the Perfect HeatTM Plus System for heating the cleaning solution.
This system uses a combination of the patent pending Perfect Heat TM coils and an inline
electrical heater.
Operation:
1. Follow operating instructions steps for filling the machine with water and cleaning solution.
2. Turn on electrical heater, switch is located on panel.
3. Pre-heat machine for 5-10 minutes before use.
NOTE: There is a valve in the upper compartment that either sends the water through the heating
components, or bypasses them. The machine is preset in the “HOT” position. To clean with cold
water, turn the valve to “COLD” or UP position. This should be done prior to filling the tank with
water. For general cleaning, it is recommended leaving the valve in the “HOT” or down position
and cleaning with hot water.

MAINTENANCE
Daily Maintenance
To maintain optimum performance, the equipment, tools and filters should be cleaned after each
use. Replace any filters that cannot be cleaned or are damaged. Nozzles that cannot be cleared
should be discarded. Wipe down the equipment with a damp cloth to keep clean and preserve
the appearance.
1. Wands and Tools
Rinse opening of tool with water to eliminate any debris.
Wand only – open and clean in-line strainer.
A. Disconnect the In-line Strainer by using the quick disconnect coupler.
B. Remove the filter and rinse with water.
C. Remove any debris from the strainer.
D. Keep o-ring and threads of the plug lubricated.
DEFOAM is a good lubricant or use a non-petroleum based lubricant. This will ensure a tighter
seal.
Wipe tool with damp cloth and store with head up to prevent clogging of nozzle.
Inline Strainer Filter
Quick Disconnect
Coupler
2. Filters
In-Line Strainer Filter – Disconnect the In-line Strainer Filter on the wand by using the quick
disconnect coupler. Remove the filter and rinse with water. Remove any debris from the strainer.
Keep o-ring and threads of the plug lubricated. DeFoam is a good lubricant or use a non-
petroleum based lubricant. This will ensure a tighter seal.
Inlet Filter – Remove the inlet filter. Dump and clean debris at the end of each cleaning job.
Main Filter – Remove the main filter sleeve and rinse out and clean thoroughly.
Pump Protection Filter – This ball-shaped filter should be in place when the tank is cleaned and
rinsed. Remove and rinse only after the tank is rinsed.

11
Periodic Maintenance
1. Check power cord for any breaks, separations, or cuts. Make sure the ground pin on the
connector is intact or the machine will be unsafe. Make sure the ground pin on all three prongs
on the twist lock connector are intact.
2. Check for plugged nozzles when using tools. If streaking occurs during cleaning, a plugged
nozzle may be the cause. A plugged or partially plugged nozzle can be identified by holding the
tool 5-7" above the surface and checking for an even spray pattern. To clean a plugged nozzle,
remove the nozzle and direct pressurized air backwards through the nozzle or backwash the
nozzle with water. A convenient method is to insert the nozzle into a garden hose ball valve,
tighten the ball valve to a faucet, and turn on the water. (Ball valves are available, part #7AX020).
Inspect nozzle and repeat cleaning procedure, if necessary. Discard nozzles that cannot be
cleared. Tool nozzles wear and must be replaced after 200-250 hours of use.
3. Occasionally open the base and inspect hose and other connections for leaks. Repair or
replace any leaking parts. Always disconnect power cord, before removing side panels.
4. It is very important to monitor machine operating hours for proper maintenance of the motors
and pumps. After 700 hours of operation, the vacuum motor brushes should be inspected by an
authorized repair station and replaced if worn (length is .5 inches or less).
5. Check vacuum motor performance using a vacuum gauge. Place this gauge on the tank inlet
fitting with the vacuum turned on. Water lift should be between 135 and 150 inches. If the reading
is lower, check for air leaks in the tank, cover gasket, and drain hose.
6. Check pump performance occasionally against built-in pressure gauge. Pump running
pressure on the PRO 500 should be 500 + 10 p.s.i, PRO 750 should be 750+ 15 p.s.i. If the
pressure is outside of this range, call your dealer or authorized service center. After 400 hours,
the pump valves should be replaced. After 700 hours of operation the pump cam bearing and
plunger should be replaced. The pressure regulator should be rebuilt after 400 hours of operation.
