4. The Tri-Mist 1400 is equipped with a 10ft power cord. Make sure the power source is within 10 ft of the Tri-Mist unit and that the power source voltage is compatible with the Tri-Mist 1400 that was ordered. The Tri-Mist 1400 is not dual voltage; check the schematic label on the inside of the filter access door.

INSTALLATION

CAUTION – The Tri-Mist Mist Control 1400 weighs 210 lbs, a crane or fork truck is recommended for the installation to avoid injury.

DIRECT MOUNT TO MACHINE ENCLOSURE
The Tri-Mist 1400 can be mounted directly to the enclosure on a machine tool. The collected mist droplets drain back into the machine tool through the air inlet of the TriMist 1400.

DIRECT MOUNT INSTRUCTIONS
CAUTION Sharp edges may be located on cut and drilled holes for this installation. Wear protective gloves during the installation.

Carefully remove all filters and ESP cells from the Tri-Mist 1400. Position the Tri-Mist
1400 on the machine tool in the desired position.

1. Use the inlet opening and the mounting hole pattern on the bottom of the Tri-Mist 1400 as a template to mark the inlet and mounting holes to be cut into the enclosure. NOTE: The inlet opening in the machine tool does not need to be as large as the inlet of the Tri-Mist 1400. It is recommended that the inlet opening be a minimum of 64 square inches.
2. Use a .281 Dia drill bit to drill the mounting holes for the ¼-20 bolts used to secure the Tri-Mist 1400 to the machine tool. There are 14 holes in the inlet flange of the Tri-Mist 1400. It is recommended that a minimum of four be used to secure the Tri-Mist 1400.
3. Apply the silicone sealant provided between the enclosure and the Tri-Mist 1400. Bolt the Tri-Mist 1400 to the enclosure.
4. Replace the filters and ESP cells. Make sure that the airflow arrows point up.

DUCTED INSTALLATION

When direct mounting the Tri-Mist 1400 isn’t possible or desired, the Tri-Mist 1400 can be installed with a plenum option bolted to the Tri-Mist 1400 inlet instead. This plenum has a drain and collars to connect to flex ducting.

2. Carefully drill the required six holes in the machine tool to attach the L-brackets from the machine mount stand using 13/32” drill bit.
3. Carefully lift the Tri-Mist 1400 onto the machine tool. Bolt the Tri-Mist 1400 to the machine tool using 3/8” nuts, bolts and lock washers.

ELECTRICAL INSTALLATION

DANGER ELECTRICAL SHOCK HAZARD
Tri-Mist 1400 system should only be installed by a qualified technician in accordance with the National Electrical Code (NEC), and the Occupational Safety and Health Act (OSHA). Improper electrical installation may damage equipment and can create a hazard causing possible injury or death.

The Tri-Mist 1400 System must be wired into the emergency stop switch on the machine
tool.

Cord Connected
The Tri-Mist 1400 is equipped with a 10-foot power cord. The 115 / 120 volt model includes a standard 15 amp rated plug. The 208-230 volt model is shipped with a 10-foot power cord with a 615-PA 2 pole plug. Please note that the Tri-Mist 1400 is not dual voltage.

START UP

1. The Tri-Mist 1400 is equipped with a variable speed controller. Run the Tri-Mist 1400 on the lowest speed that will provide negative pressure in the machine tool enclosure.
2. The indicator lights should be on when the blower is running.
3. The Tri-Mist 1400 is equipped with three test buttons to verify that the electronic filtration system is energized. Push each test button and listen for an arching sound. This indicates that the filtration system is energized.

MAINTENANCE

WARNING – Excessive accumulation on the filters (impingers and ESP cells) could result in fire damage
CAUTION – Be careful when handling the electronic cell, the metal edges may be sharp. Wear protective gloves when handling. Be careful not to damage the electronic cell, grip the cell on the frame so the thin collector plates are not damaged.
CAUTION – Tri-Mist 1400 has an interlock safety switch that disconnects electrical power to the filters when the filter access door is opened. To reduce the risk of electrical shock, do not perform any service other then filter cleaning unless power to the Tri-Mist 1400 and the machine tool has been safely disconnected and you are qualified to do so.

During the first month of operation, inspect the mist impingers and the electronic cells to help determine proper maintenance interval. When there is a buildup of coolant, it is time to clean the filters.

In general, to maintain peak performance, the Tri-Mist 1400 filters (impingers and ESP cells) should be cleaned a minimum of four times per year. This will insure maximum mist collection efficiency.

In some High Pressure Coolant applications the cells may need to be cleaned more frequently.

Parts Washer Method
The mist impingers and electronic cells can be cleaned with a parts washer. Make sure that the cleaning fluid used is aluminum safe and the maximum pressure does not exceed 65 psi. I would recommend an aqueous parts washer rather than a solvent based washer.

It is very important that the cell be rinsed very well to insure that all detergent is rinsed off. Check that the Ionizer wires are clean and smooth.

Manually Cleaning the Electronic Cells with a tub

Manually Cleaning the Electronic Cells with a Spray Bottle

Important: make sure that the detergent used is safe for aluminum and that all of the detergent is rinsed off with hot water.

• Spray detergent on the electronic cell until all surfaces on the cell are covered with detergent; allow the detergent to work on the cell for 7-10 minutes before rinsing.
• Rinse cell with hot water making sure that no detergent residue remains.
• Using a cloth, wipe each ionizer wire to remove any residual oil or water.
• On very dirty cells it may be necessary to repeat steps 1 through 3.
• Replace cell back into Tri-Mist unit after allowing cell to drip dry for 20 minutes.

Note: If water-soluble machining fluids are used, it would be best to spray a light coat of oil on to the electronic filter after washing. LPS or WD40 in a spray bottle are very effective. This light coating of oil makes the aluminum cell easier to clean for the next cleaning.

Electronic Cell Inspection

1. Check that all 9 ionizer wires are in place and that there is no buildup of dirt on the wires. The ionizer wires should feel smooth.If they feel rough then there is a coating on dirt on the wires that needs to be removed either rewash the cells and wipe the wires with a cloth our use 600 grit emery paper and carefully go over the wires. If there are missing wires they should be replaced, see ionizer wire replacement on the following page.
2. Check that the collector plates are secured to the support tubes. Loose collector plates cause arcing and can only be repaired at the factory.
3. Check that there are no foreign objects wedged between the collector plates.
4. If the cell appears to be clean and in good shape, then simply blow compressed air through the cells. Many times a foreign object is hard to see and the compressed air can dislodge it.

Manually Cleaning the Mist Impingers
Wash with a degreaser and rinse with hot water. Allow to dry or use compressed air to blow excess water off. The Mist impingers can be cleaned the same way you clean the electronic cells.
Cabinet
Using the same detergent, clean the inside and outside surfaces of the Tri-Mist once per year.

Trouble Shooting the Tri-Mist 1400

Turn the control switch on by rotating the control knob clockwise. The impeller (fan/motor) should come on as well as the Indicator Lights that confirm that the High Voltage Power supplies that energize the electronic cells are functioning properly. The Test Buttons (Red Plastic Buttons on the access door) should be pushed to confirm that the Electronic Cells are energized. Pushing the test buttons should create an arcing noise.

PROBLEM:

1. Indicator Light is out – Please note that the Indicator Lights and the Impeller
   (fan motor) operate independently. If the indicator light/lights are out, the
   Impeller should still be moving air. If the indicator lights are out and the Impeller
   is not moving air then the problem is one of the following:
   a. No power to the Tri-Mist unit
   b. Defective Control Switch
   c. Defective Interlock Switch or poor alignment between the door tab
   actuator and the interlock switch.
   If the indicator lights are out and the Impeller is moving air then the problem is one of the
   following:
   a. Defective High Voltage Power Supply. There are three high voltage power
   supplies, one for each set of cells. There are three Indicator Lights on the TriMist 1400 triple pass. The top Indicator Light is for the top two Electronic
   Cells; likewise the middle Indicator Light is for the middle Electronic Cells
   and the bottom indicator light is for the bottom Electronic Cells.
   b. Dirty / shorted out Electronic Cells. If the top Indicator Light is out, then the
   problem is with the top two Electronic Cells or the High Voltage Power
   Supply that energizes the two cells.To determine if the problem is with the High Voltage Power Supply or the Electronic Cells, remove the Electronic Cells and turn the unit on. If the Indicator Light comes on then the High Voltage Power Supply is fine and the problem is with one or both of the Electronic Cells. You can slide one cell in at a time to determine which cell is defective. Once you have determined which cell is creating the problem, and then proceed to Electronic Cell inspection below. If the Indicator Light does not come on with the cells removed from the unit then the problem is with the High Voltage Power Supply. The power supply will need to be replaced. There are (4) hex nuts to remove and (6) wires. All wire connections are quick clips that slide off of the wire terminals.

Tri-Mist 1400 – Metal Working Fluid Connections

The Tri-Mist 1400 can operate with all metal working fluids. If the coolant is water based, we then need to remove the P4 wire connections on all three High Voltage Power Supplies.
DANGER – ELECTRICAL SHOCK HAZARD:
Make sure power is disconnected before removing the access cover.
