TOOLS AND EQUIPMENT REQUIRED

The following list of tools that would be needed for a typical installation:

• Drill
• Reciprocating Saw
• Hand tools

PLANNING THE INSTALLATION

WARNING- This Mist Collector is not explosion proof, do not use in explosive atmospheres.

1. The Tri-Mist 850 should be located with consideration for access to the hinged door and the electrical compartment cover. The filter access door requires a minimum of 20” clear in front of the door.
2. The side access cover on the right hand side should be accessible, if possible.
3. Mount the Tri-Mist 850 as far from the chip conveyor opening as possible.
4. The Tri-Mist 850 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 850 that was ordered. The Tri-Mist 850 is not dual voltage; check the schematic label on the inside of the filter access door.

DIRECT MOUNT TO MACHINE ENCLOSURE

DIRECT MOUNT INSTRUCTIONS

3. Apply the silicone sealant provided between the enclosure and the Tri-Mist 850. Bolt the Tri-Mist 850 to the enclosure.

4. Plug the Tri-Mist 850 into the correct power source. Note that the Tri-Mist 850 is not dual voltage. The schematic on the inside of the filter access door has the correct voltage for the Tri-Mist 850.

5. Replace the filters and ESP cells. Make sure that the airflow arrows point up.

DUCTED INSTALLATION

When direct mounting the Tri-Mist 850 is not possible or desired, the Tri-Mist 850 can be installed with a plenum option bolted to the Tri-Mist 850 inlet.

INSTALLING THE PLENUM / STAND

Typically the plenum stand is installed at the factory. If it is to be installed in the field, attach the plenum to the inlet opening using the supplied gasket and ¼ -20 hardware.

Note the drain on the bottom of the plenum.

CEILING MOUNT

WARNING For ceiling mounting, you must consider the weight of the Cool Blaster Mist Control system, the ductwork and oil being collected. All ceiling support members must be sized to properly support the unit, ductwork and drain hardware.

DRAIN INSTALLATION

The Tri-Mist 850 plenum has a ½ inch pipe thread (female) fitting for a drain. A P-trap is required for the metal working fluids to drain properly.

Prime the P-trap with the metal working fluid to avoid air being drawn through the plenum. The P-Trap can consist of a loop in a PVC hose or a hard pipe.

INSTALLING THE MACHINE MOUNT STAND

Carefully drill the required four holes in the machine tool to attach the plenum/stand to the machine tool. Carefully lift the Tri-Mist 850 onto the machine tool. Bolt the Tri-Mist 850 to the machine tool using 3/8” nuts, bolts and lock washers.

ELECTRICAL INSTALLATION

DANGER ELECTRICAL SHOCK HAZARD
Tri-Mist 850 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 850 System must be wired into the emergency stop switch on the machine tool.

Cord Connected
The Tri-Mist 850 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 without a plug. A field supplied plug will need to be provided to match the 208-230 volt power outlet. Please note that the Tri-Mist 850 is not dual voltage.

START UP

1. The Tri-Mist 850 is equipped with a variable speed controller. Run the Tri-Mist 850 on the lowest speed that will provide negative pressure in the machine tool enclosure.

2. The indicator light should be on when the blower is running.

3. The Tri-Mist 850 is equipped with two 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 Procedures for Tri-Mist

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 thin collector plates are not damaged.

Caution- Tri-Mist 850 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 850 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 850 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.

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.

Replacing ionizer wires

Broken or bent ionizer wires can cause an electrical short to ground, often resulting in visible arcing. Do not use cells until broken wires are removed. Cells can be used with one missing wire, but replace the wire as soon as possible.
Replacement wires are supplies, cut to length with eyelets on both ends for easy installation.

1. Hook the eyelet on one end of the wire over the spring connector on one end of the cell. See figure.
2. Hold the opposite eyelet with needle nose pliers and stretch the wire the length of the cell. Depress the opposite spring connector and hook the eyelet over 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.
