2.1. General Rules
The Purge Series has been designed and constructed in such a way to minimize
any possible cause of danger to the operator and their surroundings. However,
residual risk still remains and can arise through improper use of the machine and
can be of various types:
•Risk due to escaped coolant/cutting fluid.
•Risk due to excessive noise caused by operating outside permitted limits.
•Risk of accidents caused by scraping against edged sheet metal profiles.
2.2. Prevention of Mechanical Risks
In operation, the Purge Series contains some moving parts. These parts constitute a
possible source of danger to the operator, therefore in order to avoid any possible
danger it is necessary to observe the following operational rules:
•Before removing any panels/guards, ensure electrical supply to the
machine has been switched off.
•Never start the Purge Series with any panel/guards removed.
•The additives present in coolant/cutting fluid may have a corrosive action
that can irritate the skin and eyes.
oAlways wear gloves & eye protection when handling
coolant/cutting fluid.
2.3. Prevention of Electrical Risks
When power to the machine is switched on, the machine is a source of danger,
especially if the basic safety rules are not followed. In order to avoid any possible
danger it is necessary to observe the following basic operation rules:
•When making electrical connections to the Purge Series, observe state
and federal electrical codes or those otherwise in force. Observe the
technical & electrical supply conditions imposed by the power supply
companies.
•Before carrying out any work on the Purge Series, switch off the electrical
supply at the main isolator.

3. Intended Uses
3.1. Why the Purge Works
3.1.1. Without the Purge
•Coolant and chips run through the machine and go into the “dirty side” of
the machine tank.
•Coolant flows from dirty side to clean side through a screen, which
collects chips and debris.
•As the screen gets blocked, coolant can no longer flow into the clean
side, starving the pumps.
•The loss of coolant can cause poor part finish, increase tooling wear, out
of tolerance parts, and alarming out in the middle of a part cycle. In some
cases, there is no alarm for loss of flood coolant, which could allow the
problem to cause more and more damage until it is found and resolved.
•To resolve the issue properly, the machine must be shut down, the tank
drained and removed from under the machine, chips removed, and
screens cleaned. Everything then must be put back together; the tank
moved back into place, hoses reconnected, pumps plugged back in, tank
refilled with coolant, and then the machine can be turned on and run
again, repeating the cycle.
3.1.2. With the Purge
•Coolant comes out of the tool or nozzle, falls down with chips, (goes
through chip conveyor), and goes into a collection funnel in the “dirty side”
of the tank.
•The Purge system pulls in coolant and chips from the funnel at a rate
faster than is being provided. This creates a difference in fluid level
between the inside and the outside of the funnel, pushing chips towards
the Purge collection dip tube.
•The fluid with chips is pumped through a set of filters that are selected
based on material and cutting process, and can be easily changed to
meet the needs of different part programs in the future.
•The chips are collected in the filter bags and the coolant flows back to the
clean side of the tank.
•The volume of fluid coming in to the clean side of the tank exceeds the
volume being pumped out, again, creating a fluid height difference,
pushing all debris in the tank towards the Purge collection dip tube and
away from the pumps, while also providing the pumps with more than
enough coolant so they never pull in air.
•When the Purge filters are dirty, the Purge will alarm out but will not stop
the machine tool. The Purge can then be shut down to quickly and easily
replace the filters, which results in more coolant up time.

5. Moving & Storage
5.1. Delivery Checks
When taking delivery of a machine, ensure that the
machine has been transported in the correct position.
Carefully check the physical condition of the box for any
signs of external damage. If there is evidence of damage,
remove the packaging to ensure there is no damage to the
contents of the skid. In case of damage, DO NOT accept
the goods and immediately inform MP SYSTEMS. If you
are unsure if there is damage to the contents and accept
delivery, you must write “Damaged” on the delivery
receipt.
In the event of irregularities during transit, the freight company will bear the full responsibility for
any damage suffered.
5.2. Transport & Carriage
The machine must be transported in a vertical position, as shipped. The tank MUST BE EMPTY
before moving. The Purge Series has been constructed to be moved by fork truck.
The machine must be moved in such a way as to avoid the risk of damage.
Do not attempt to lift the machine with equipment that is inadequate or unsuitable, especially
with equipment that is too small for overall weight of machine. Refer to Section 4.2.
Mechanical Specifications for unit weight.
Only trained and licensed Fork Truck operators may transport this machine. MP SYSTEMS is
not responsible for any damage caused by unauthorized use.
WARNING: Do not transport machine with fluid in tank.
5.3. Storage
The Purge Series must be stored in a cool and dry environment, avoiding all
extreme conditions including freezing conditions. All coolant must be drained
from machine before being stored. If utilizing water based coolants, the system
must be flushed before storage, please refer to the coolant manufacturer for
correct flushing agent. Removing all coolant from the system will ensure
coolant does not become contaminated while in the system. Contaminated
coolant may lead to malfunctions.
Not properly draining/flushing Purge Series before storage can lead to
bacterial growth, which will contaminate any coolant it comes into contact
with. Contaminated coolants effectiveness is also greatly reduced.

•Phillips (Cross) Head Screwdriver
•Flat Blade Screwdriver
•Electric Drill
•7/8” UniBit (Step Drill)
•1 ¼” Conduit Punch or equivalent size hole saw
•12” Pipe Wrench (Minimum)
•Metric Hex Keys
•Teflon Pipe Tape / Liquid Pipe Sealant
When installing MP Systems products, the correct location of the dip tubes is important
to a successful install. The best way to do this is to use a preexisting hole in the tank
can be used to pass the various pipes through the tank top. This is not only quick and
easy, but also gives you a perfect window to be able to see what is going on in your
tank for troubleshooting. Sometimes, this is simply not an option and a hole must be
drilled in the tank.
If you find yourself in a pinch, most hardware stores like Home Depot or Lowes will have
the required hole saws available, you will want to find a bi-metallic hole saw like a
Milwaukee or Lenox depending on which store you go to. These tend to be the best
option in a hurry, however they will wear out, so if you have a lot of holes to drill, it may
be wise to purchase more than one.
If you know ahead of time that you will need them, then they can be ordered from
McMaster, or MP Systems stocks and can ship a kit with all the necessary components.

Cutting a hole in sheet metal seems like a common task,
however doing it right will not only be safer, but can also
improve tool life, cut speed, and cut quality (clean vs. jagged
edges).
1. Start by measuring twice. Use the green pipe clamp
for the dip tube you are installing to help layout where
the hole needs to be drilled, as well as where the
fasteners will need to go for the clamp. Use a center
punch to locate the holes and prevent drill drift.
2. Use the appropriate size drill to make a pilot hole in
the center of the cut. *NOTE* Only the drill should be
used at this point, do not use the drill bit while
attached to the hole saw. When the drill breaks
through, you can damage the hole saw by “punching”
the sheet metal and breaking or bending the teeth.
3. Install the blank pin in the arbor, then thread on the
hole saw. (In a pinch, an old drill bit installed
backwards can work as a guide too) Be sure to set
your drill to low speed and change from drilling to
torque mode.
4. Apply cutting fluid and begin cutting, feathering the
trigger to maintain a moderate speed.
5. Be sure to continuously add cutting fluid to keep the
hole saw cool and lubricate the cut.
6.3. Electrical Installation
Before connecting electrical power, pay close attention to the electrical data on machine
plate. Ensure that the voltage of the power supply is compatible with that specified on
plate. All installation work must be carried out by qualified personnel. Always consult
machine tool wiring diagram before connecting power.
LOCK OUT/TAG OUT any and all power disconnect switches
before performing any work on equipment.

11 MPSYSTEMS-M-011/02 (Purge Operator)
Be sure to observe local and federal electrical codes in effect.
Observe the technical supply conditions imposed by the power
supply company.
6.3.1. Selecting Voltage
Many large industrial facilities run on 480v 3phase @ 60Hz electricity. Most machine tools in the
United States require a step down transformer as the machine tools, typically, run on 200 +/-
10% VAC. 208-230v is the standard voltage for MP Systems units. (Optionally, 480V units
can be purchased, voltage cannot be changed in the field)
Utilizing machine tool voltage makes lockout/tag-out far easier and allows it to comply with most
local regulations.
Power can either be pulled from a separate drop, or from the machine tool using the provided
circuit breaker in the installation kit if the machine tool breaker allows.
6.3.2. Power Harness Installation
1. Mount supplied power harness with hardware provided in the installation kit and route
the cable:
•If ¾” conduit plug is not available, knock out hole and use supplied cord grip.
2. Wire power cable in parallel with machine tool power:
•Be sure to leave enough cable to properly ground the unit.
3. Locate proper grounding point. Attach using supplied ring terminals.
3 phase power installation should only be performed by qualified personnel.

12 MPSYSTEMS-M-011/02 (Purge Operator)
6.3.3. Control Signal Installation (Optional)
Using machine tool control signals is not recommended by MP SYSTEMS. If required for your
application, please contact MP SYSTEMS for more information.
6.4. Inlet Installation
6.4.1. Suction Dip Tube Placement
One of the biggest factors of a successful Purge install is where you place the suction dip tube
in the tank. There is only one suction tube and it can only be placed in one location.
MP SYSTEMS recommends placing the suction point either immediately adjacent to the chips’
point of entry as depicted in Example A, or in the path of high velocity coolant, as depicted in
Example B.
•The maximum chip size the Purge can handle is ¼”. If larger chips are present, an
optional screen or basket can be added to separate the larger chips out.
•In less than ideal cases where some of the debris may be missed, the Purge will still
provide an excess of clean coolant directly to the clean side of the machine tool tank.
•This will provide the machine tool with more coolant up-time, however you may have
to clean out the tank periodically. Also, because of the Purge’s high flow, it will
eventually capture debris that is in suspension, even with a poorly placed dip tube.
The illustrations on the next page show various conveyor/tank conditions and how the Purge
might be installed.
6.4.2. Feed Pump Installation
1. After locating your collection point, the feed pump must be put on the floor, as close as
possible to the collection point, prior to connecting the dip tube.
2. Connect your dip tube to the inlet of the feed pump using the shortest hose possible.
•Use supplied hose clamps to secure hose during installation.
3. To prime, add coolant into the outlet of the feed pump until the coolant trickles out of the
inlet.
4. Attach the hose between the feed pump outlet and the Purge inlet.
•Use supplied hose clamps to secure hose during installation.
5. Run the yellow cable attached to the feed pump to the bottom of the purge electrical
panel and plug it into the matching connector.
Refer to the Floor Layout in Section 4.3 for a visual example.
Do not place hoses on top of unit or stand vertically.

Perfect! This is the best case for the
Purge. All of the flow from the
conveyor is directed immediately into
the dip tube.
In this case, the exit is very wide,
however all of the flow is getting
directed down a known path. This
smaller channel, whether it be part of
the conveyor or part of the tank
geometry, increases the velocity of the
fluid and directs it right into the Purge
dip tube.
This is a less than ideal situation. With
a long exit, or multiple exits along the
same side, some of the coolant at the
far ends can be missed by the dip
tube. The purge will still work and will
collect the majority of the debris, but
you won’t have the same level of
collection.
When a conveyor has exits on both
sides, or when the conveyor has more
than one exit and they are far apart,
the Purge cannot collect everything. In
this case, the Purge would only collect
half of the debris missed by the
conveyor.

6.5. Return Installation and Hose Routing
6.5.1. Return Installation
The bottom of the return pipe is cut at a 45° angle. Be sure to point the dip tube into the tank
and not into a wall. Tank tops usually have multiple cutouts in the clean section of the tank for
various pumps and accessories. One of these holes can be utilized for the Purge return, but try
to use one farthest from the screen.
6.5.2. Hose Routing
The Purge uses a gravity based return. Because of this, the hose must be as short as possible
and have a continuous downward slope as depicted in Example A below. If the hose goes under
the tank level or over the top of the Purge, as depicted in Example B and C, it can block the flow
of coolant, causing an alarm.
•Use supplied T-Bolt Hose Clamp to connect hose to Purge outlet.
•Use normal supplied hose clamp to secure hose to dip tube.
6.6. Filling the Tank
1. Fill machine tool coolant tank with
coolant/cutting fluid.
2. To access the Purge tank for filling,
unscrew four of the wingnuts and
remove one of the filter tops.
3. Fill Purge tank with 30 Gallons of
coolant/cutting fluid.
•Be sure to use the same coolant
being used in machine tool tank.
4. Replace filter top and hand tighten
wingnuts.

7. Operation
7.1. PLC Set Up and Settings
7.1.1. PLC Initial Set Up
After connecting all hoses and power, the Purge can be turned on and the PLC set up.
1. If there is a screen in the tank that separates the clean and dirty side, be sure to clean
the screen if installing on a machine tool that has already been run. Obstructions
between the clean and dirty side can prevent proper operation.
2. Go into the settings on the PLC and confirm the amp settings match your motor name
plate.
•These are the default settings for min and max amps. These are average values
that will allow the unit to get started. Changing these values to match your motor
will allow the Purge to run at its best.
LOW VOLT
HIGH VOLT
MIN AMP
3.0
2.0
MAX AMP
8.0
4.0
•The motor plate will list “AMPS” or “FLA” depending on manufacturer. This is the
MAX AMP value.
•The MIN AMP should be set to the current the motor pulls when it is sucking air.
This can be found by running the motor for a few seconds before hooking up the
hoses, or if it has already been installed, by raising the dip tube out of the tank to
make the pump suck air briefly.
3. Turn on all of the coolant pumps in the tank
•You should see the coolant flowing into the clean section from the dirty section
through the screen. The coolant on the clean side of the screen will be lower than
the dirty side.
4. From the main screen, start the Purge and wait 30 seconds.
•The first time you turn on the Purge, there will be air in the hose which might
alarm out the machine. This is OK.
•If it alarms, clear the alarm and restart from the main screen until coolant flows.
•If you get more than 5 consecutive alarms, check for loose connections or
blocked inlet.
•If the problem persists, contact MP SYSTEMS.
5. Check to make sure the coolant is flowing through the screen in the reverse direction.
The coolant in the clean side should now be level with or higher than the dirty side.
•If the coolant is not flowing in reverse, hit “STOP” on the PLC Screen, go to
“SETTINGS”, and increase the FLOW value.
•Once the FLOW Value has been entered, go back to the main screen and select
“START”.
•Continue to increase the flow value until reverse flow is achieved.
