SET-UP AND OPERATION
500PSI AND HEAT
CAUTION!
Use care when handling hazardous chemicals.
Never leave the machine running when you are not actively using it.
Always use a defoamer when foaming occurs to prevent vacuum motor damage.
DANGER!
Do NOT use solvents, or any chemicals that may be fl ammable, explosive or combustible.
CLEANING SOLUTIONS:
Select a proper pre-spray for the surface to be cleaned, and apply the pre-spray. Use a neutral pH rinse or detergent (6 to 10 pH) in the MC1200 to prevent
premature wear of the pumps, seals, and other components. Damage caused by the use of improper or strong chemicals is not covered by warranty. Powdered
chemicals are not recommended.
1 Before each use, inspect the machine, hoses, and cleaning tools for cleanliness and completeness. Make sure the hoses are in good condition and
the spray nozzle(s) is tight. Be sure the Pre-Filter Bag (27) and the Dump Pump Inlet Filter (25) are installed and are clean.
2 When not using the auto-dump feature, just make sure the brass cap is screwed tightly on the Dump Hose Connection (18) on the dump pump on
the rear of the machine. If you choose to use the auto-dump, connect the dump hose to the Dump Hose Connection (18) on the back of the dump
pump, and place the open end of the hose in a drain. Make sure the Recovery Tank Drain Hose (17) is closed, and the Recovery Tank Lid (2) is
closed tight.
REFER TO THE AUTO-FILL AND AUTO-DUMP INSTRUCTIONS ON THE FOLLOWING PAGES.
3 If you choose to use the auto-fi ll feature, connect the fi ll hose to the Auto-Fill Hose Connector (7). Turn on the water source, and allow the tank to fi ll
with water. When using the auto-fi ll system, the auto-fi ll fl oat will automatically turn on and turn off as the tank empties and then fi lls. NOTE: If you
are not going to use the auto-fi ll system, just fi ll the tank with water and cleaning chemical. Follow chemical directions regarding dilution and mixing.
Do not use harsh chemicals; they may damage seals in pumps and valves, and cause the pump to wear prematurely.
NOTE: Using warm water in the tank may improve the effi ciency of the heat exchanger when cleaning with heat, but never use water with a
temperature exceeding 130 °F / 54 °C.
4 Pre-spray the area to be cleaned, with a pump-up sprayer, while the tank is fi lling. Follow chemical directions.
5 Plug in the two power cords (22). Do not connect both cords to the same outlet. The green, 'separate circuit' locator light (A) on the switch plate
should light up. If the locator light does not come on, check the circuit breaker box in the wall, and/or try different outlets until it does turn on.
Although all systems in the machine may work correctly if you are not on two circuits, a circuit breaker in a wall panel may trip. If you make sure the
green light is turned on, you will prevent tripped circuit breakers. Select 'HEAT" by placing the HIGH PRESSURE/HEAT Switch (B) in the DOWN
position.
NOTE: This switch is off when it is set to the middle position and neither the 1200 PSI pump nor the heater are selected. When set to the bottom
position, the heat is selected; the red light will come on and stay on. The heater and the 1200PSI pump cannot operate at the same time.
6 Press the lever on the Pressure Relief Valve (23) to make sure there is no back pressure in the system.
7 Connect the priming/siphon hose to the 500PSI Quick Connect (10) and turn on the pump (E) and place the open end over the Holding Tank (14).
The air should prime out of the pump within 20 - 60 seconds. Watch the water fl ow into the tank. When the water is clear (no air in it) and is fl owing
strongly, turn the pump off and remove the priming hose. NEVER remove the priming hose while the pump is still running.
8 Connect the Solution Hose (24) from the reel to the 500PSI Quick Connect (10) and connect the Vacuum Hose (28) from the reel to the Vacuum
Hose Connection (1). Connect both hoses to the cleaning tool.
9 Turn ON the 500PSI pump (E). Set the pump to the desired pressure by adjusting the 500PSI Pressure Adjust Knob (13) while you are spraying and
watching the 500PSI Gauge (12). NOTE: The gauge will only read pressure while you are spraying.
10 Spray for a few seconds to fi ll the lines with solution. Wait two minutes to allow the heater to reach temperature.
11 Turn on the vacuum (D) and turn on the dump pump (F). Begin cleaning. NOTE: The dump pump will automatically turn on and turn off as the tank
fi lls and then empties (refer to drawings on following pages). It may take several cycles to heat the lines and the cleaning tool.
12 If you are not using the auto-fi ll and auto-dump features, turn off both the pump (E) and vacuum (D) when the Holding Tank gets low, fi ll the Holding
Tank, and empty and clean the recovery tank.
13 When fi nished with the job, turn off the water source (if using Autofi ll).
ELECTRIC CIRCUIT LOCATOR: This system will inform the operator when the two cords are plugged into separate circuits by turning on the green,
circuit locator light (A). This helps to prevent tripping circuit breakers.
NOTE: If the green circuit locator light (A) does not illuminate when the cords are plugged in, then both cords are on the same circuit. Try other outlets
with one of the cords until you get the locator light to come on.
