•

Be sure to maintain the liquid level in the tank within the specified range. (See page .)

(Operating the unit with a liquid level out of the specified range causes a fault of the unit.)

• The OILCON unit incorporates a delay timer. Therefore, when the compressor is stopped once and then restarted, the

compressor may not start. This does not mean a fault of the unit.

(See page .)

• The OILCON unit can be used for water-soluble cutting/grinding fluid, cutting/grinding oil, water for industrial use, lubricating

oil, hydraulic oil (mineral oil). It cannot be applied to the following oils (liquids), and a liquid that may corrode the cooling coil

(SUS304).

CAUTION

Before Operation

Before operating the Oil Cooling Unit, check the following items:

Operating environment

• Check the atmosphere for any factor (dust, oil mist, high temperature, high humidity, etc.) that may adversely affect the unit.

•

Check if the unit is not installed in explosive atmosphere (that may cause evolution, inflow, retention or leak of inflammable gas).

• The operating range is limited. Make sure that the operating conditions are within the following range.

(Note: If this unit is operated out of the specified range, the protection devices may be activated, or the service life may be shortened.)

Electric wiring

• Check if the cable size is larger than the specified size. (Refer to “Wiring procedure” on page .)

• Check if the ground cable is securely connected.

• Be sure to use a commercial power supply. Using an inverter power supply may result in burnout.

• Check if the power supply voltage is within the following range:

50 Hz...........200 V ±10%

60 Hz...........200/220 V ±10%

• Check if a circuit breaker is provided exclusively for each Oil Cooling Unit.
