How to..

Unpack Unit

  1. Inspect unit carefully for any possible damage during transit. Some damage may not be noticeable until unit is installed.
  2. Notify shipper of any damage immediately. Claims must be filed within 15 days.

Installation

  1. The DM Oil Mist Collector requires some mechanical installation:
    • Units are typically mounted on the optional floor stand or rod hanging brackets.
  2. Additional duct work may be required to complete installation. Consult your dealer or the factory for the correct materials to use for your application:
    • A qualified mechanical contractor should be used to ensure unit installation meets all applicable building codes.
  3. Each unit is supplied with a 1-1/4 NPT drain in the sump of the unit:
    • The drain must be correctly connected to the machine tool sump or external reservoir prior to operation of the mist collector.
    • The inlet plenum of the collector is not intended to act as a reservoir for the collected coolant and must drain properly for the unit’s performance.
    • A trap should be used to make sure air does not flow through the drain into the collector.
    • A good alternative to a standard p-trap, is to submerge the end of the drain line, into at least 4 inches of coolant. This will prevent backflow and also eliminate clogs which may form in a p-trap.
  1. Using a vacuum, remove dirt accumulations in and around vent openings:
    • Dirt accumulations can cause the motor to overheat and pose a fire hazard.
    • Enclosed motors can be cleaned with an air jet (wear eye protection).
  2. Periodically inspect the installation:
    • Check for dirt accumulations; unusual noises or vibration; overheating; worn or loose couplings, sheaves and belts; high motor current; poor wiring or overheated connections; loose mounting bolts or guards; and worn motor starter contacts.
  3. Dayton ball-bearing motors without lubrication provision do not require periodic relubrication. Where motor has provision for bearing lubrication, lubricate as follows (frequency depends on use):
    • After stopping motor and disconnection power, thoroughly wipe the housing around both of the motor bearings, filler and drain plugs (on TEFC) ratings, remove fan cover for access to plugs.
    • Remove filler and drain plugs and install a 1/8” pipe thread lube fitting in filler hole.
    • Using a low pressure grease gun, pump new grease into motor until it appears at the drain hole.
    • Run motor for several minutes to discharge excess grease. Shut motor OFF, replace filler and drain plugs, and reinstall fan cover.

Troubleshooting

  1. You may have a blown fuse:
    • Replace with time-delay fuses.
    • Check for grounded winding.
  2. The voltage may be too low at motor terminals due to line drop. Consult local power company.
    • Increase wire size.
    • Check for poor connections.
  3. The overload in motor starter may have been tripped:
    • Check and reset overload relay in starter.
    • Check heater rating against motor nameplate current rating.
  4. Overload (internal thermal protector) may have been tripped:
    • Check motor load.
    • If motor has an automatic or manual reset thermal protector, check if tripped.
  5. Improper line connections:
    • Check connections against diagram supplied with motor.
  6. Check to see if the motor is overloaded:
    • Reduce load or increase motor size.
  7. If the problem continues, contact Diversitech support for assistance.
  1. The motor may not be applied properly:
    • Consult motor service firm for proper type.
    • Use a larger motor.
  2. The voltage may be too low at motor terminals:
    • Increase wire size.
    • Check for poor connections.
    • Check for voltage imbalance (3-Phase).
  3. The starting load may be too high:
    • Check load motor is carrying at start.
  4. There may be excess loading and/or tight belts:
    • Reduce load and/ or adjust belts.
    • Increase motor size.
  5. The motor may be defective:
    • Repair or replace.
  6. The starting torque may be inadequate or the inertia load may be too high:
    • Replace with larger motor.
  7. If the problem continues, contact Diversitech support for assistance.
  1. Check to see if the motor is overloaded:
    • Reduce load or increase motor size.
  2. Check the motor voltage as it may be too low:
    • Verify that nameplate voltage is maintained.
  3. If the problem continues, contact Diversitech support for assistance.
  1. Check the motor shaft to see if it’s misaligned:
    • Realign if needed.
  2. The 3-phase motor may be running on single phase:
    • Check for open circuit, blown fuses or imbalanced voltages.
  3. The voltages may be high or imbalanced:
    • Check wiring connections. Consult local power company.
  4. The bearings may be worn, damaged, dirty or overloaded:
    • Replace bearings.
    • Check loading and alignment.
  5. Check winding to see if it’s defective. Check the shaft to see if it’s bent or bowed:
    • Repair or replace.
  6. Check for a loose sheave or misaligned coupling:
    • Tighten set screw(s); realign coupling.
  7. If the problem continues, contact Diversitech support for assistance.
