How the System Operates
The MC600M pump system is a low pressure gear-type pump. Lubricant is drawn in on one side of the
gears 1,carried around to the outside, and forced to the output. If the flow capacity of the pump is not used, the
excess lubricant will bypass an internal relief valve 2and recirculate back into the tank.
The 30 psi pump output is further reduced by a pilot-operated fluid regulator 3controlled by the tank pressure
regulator on the MC800 controller. The fluid regulator provides an operating range of 130. bar (15 psi) to 2.07 bar
(30psi).
IMPORTANT NOTICE: Caution should be used when selecting a lubricant to use with the MC600M system. Fluids
with a flash point lower than 38° C (100° F) are not recommended, as they could present a fire hazard. Examples of
products with low flash points are kerosene, acetone, general mineral spirits, naphtha, and other solvents. Please
check the product SDS carefully before using the intended product in this system.

Pump Tank Features
1. Low Level Switch
Prevents the system from operating without
lubricant when connected to the emergency stop
circuit. Switch opens when the tank level is near
empty.
2. Fluid Bypass Valve
Automatically bypasses excess flow capacity of
the pump. Bypass lubricant recirculates into the
storage tank.
3. Inlet Filter Screen
Screens out contaminants that may enter the
inlet of the pump.
4. Fill Hole Cover
Prevents contaminants from entering the tank.
5. Removable Filter Screen
Screens out contaminants that may enter during
the tank filling process.
6. Shut-off Valve
Used to block fluid flow when servicing the filter.
7. Bleed Valve
Used to purge air when priming the system.
8. Fluid Regulator
Pilot-operated regulator provides control of fluid
pressure.

System Assembly
First, place the MC600M system away from traffic areas and position the tank to allow for convenient refilling.
HIGH VOLTAGE! Pump must be wired, grounded and fused in accordance with local regulatory requirements.
DANGER
1. Before connecting the power, view the label located on the motor to ensure that the voltage matches your input
voltage. If not, see the diagram on page 7. Reconfigure the wiring inside of the motor terminal cover to
match the schematic on the side of the motor.
2. Connect the power.
3. Mount the filter and regulator assembly on the MicroCoat stand or other suitable mounting location. Ensure that
the filter hangs vertically as illustrated.
4. Connect the fluid feed line from the MC600M to the shut-off valve on the inlet side of the filter housing. Secure
with the clamps supplied.
5. Connect the black air line connection from the MC800 controller tank air outlet to the fluid regulator air inlet as
shown.
6. Connect the fluid feed line from the regulator output to the fluid inlet of the MC800 controller as shown.
7. Lubricate the oil filter gasket lightly and install the filter on the housing. Tighten the filter 3/4 turn by hand. Do
not overtighten.
8. Rotate the inlet shut-off valve to the “OFF” position.
9. Refer to the MicroCoat system operating manual for wiring the press emergency stop circuit and connecting the
low level switch cable to the controller.

System Setup
Check All Connections
DO NOT RUN THE PUMP DRY.
CAUTION
1. Check that all connections are correct and secure.
2. Lift the cover of the MC600M and fill the tank with clean lubricant.
See the note on page 4 regarding the fluid flash point.
CAUTION
3. Close the cover.
4. Place the “System Pressure” on the MC800 controller in the “ON” position.
5. Set the MC800 tank pressure regulator to a minimum of 1.03 bar (15 psi).
6. Start the MC600M to begin lubricant flow to the filter assembly.
7. Slowly open the shut-off valve. Check for leaks.
8. Install the filter housing purge line into the bleed valves as shown in the system diagram. Open each bleed valve
and direct the purge flow into a container. Purge slowly until all air is eliminated. Do this for both bleed valves.
Preventive Maintenance
Before performing any maintenance, set the “System Pressure” to the “OFF” position and disconnect power.
WARNING
The MC600M is designed for long life with minimal maintenance. To ensure trouble-free performance, follow these
precautions and preventive maintenance steps.
• Always use clean lubricant.
• Check for residue at the bottom of the tank and clean if necessary. Keep cleaners away from the motor, lower
motor bearing and wiring.
• The electric motor requires no lubrication.
• Do not restrict the vents on the motor. Keep oil and debris from accumulating around the motor.
• To avoid pump damage, do not remove the filter screen from the pump intake.
• Replace the lubricant filter (P/N 7017347) every 6 months or 1000 hours of operation.

Troubleshooting
Problem Corrections
Lubrication flow reduced 1. Ensure that tank air pressure is set at a minimum of 1.03 bar (15 psi).
2. Replace the oil filter.
3. Ensure that the shut-off valve is fully open.
4. Check the fluid inlet screen to ensure that there is no debris blocking the
inlet.
5. Check the hoses to ensure there are no bends or restrictions.
6. Viscosity of the lubricant is too heavy (500 SUS maximum).
7. Check the voltage, cycle and phase to ensure that the pump is operating on
the right electrical current.
8. Ensure that the pump inlet is submersed.
9. Check the relief valve for dirt or chips lodging on the valve seat, preventing
the ball from closing and causing liquid to constantly bypass.
10. Check that motor rotation is free and does not bind. The motor and pump
may not be aligned. If there is binding, loosen the (2) nuts that hold the motor
to the pump casting, rotate the pump casting until it is aligned and the pump
runs freely. Retighten the nuts carefully.
