Installation Procedure Installation
Precautions for Installation
Note) 1.About the specified liquid level range
1) During cooling operation with the liquid level lower than the specified range, the moisture of the atmosphere
condenses on the exposed part of the cooling coil, causing the condensate to be mixed into the liquid.
If the liquid level further decreases, it results in cooling capacity deterioration, and also causes a fault of the
unit.
2) During heating operation the liquid level lower than the specified range, the heating element of the heater is
exposed or discolored, or may emit burning smell. If the liquid level further decreases, the heater activates the
overheat protection device. This condition hinders normal operation, and also causes a fault of the unit.
3) If the liquid level falls below the specified range due to liquid level fluctuations during operation, the liquid over-
flows from the tank. To prevent the above 1) to 3) problems, be sure to maintain the liquid level within the
specified range.
∗Mount a float switch to ensure that the liquid level in the tank is within the specified range.
2.Give thorough consideration to the layout of the partitions and inlet/outlet piping for the installation tank, so that
the low-temperature liquid that has been cooled with the OILCON unit can be uniformly mixed with the high-tem-
perature liquid returned from the machine.
Installation place and oil piping
 To install this unit, select a place that meets the following conditions:
 Do not place an object that may block air flow within 500 mm from the air intake/exhaust port.
1. Level, rigid floor (Inclination: 5˚ max.)
2.
A place where the unit is not exposed to direct sunlight or heat
3. A place with proper ventilation and little humidity
4. A place where exhaust air does not circulate (exhaust air will
not be taken into the unit)
5. A place that allows easy access to piping and wiring
6. A place with little contaminant, waste, dust particles or
oil mist
7. A place free from explosive atmosphere (evolution, inflow,
retention or leak of inflammable gas)

approx. ±5%.
∗2: Be sure to use a commercial power supply. Using an inverter power supply may result in burnout. Voltage fluctuation range should be
within ±10%.
If voltage fluctuation exceeds ±10%, consult DAIKIN.
∗3: For the different-voltage model, three types (–E1, –E2 and –E3) are available depending on the power supply voltage. (see page .)

• 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).
1) Flame-resistant hydraulic oil Phosphoric ester type
Chlorinated hydrocarbon type
Water + glycol type
W/O, O/W emulsion type
2) Chemicals and food liquids (drinking water etc.)
3) Fuels (kerosene, gasoline, etc.)
4) Water other than for industrial use
6
Before operating the Oil Cooling Unit,
be sure to read through this instruction
manual and understand the contents of
this manual.
CAUTION
Before Operation
Before operating the Oil Cooling Unit, check the following items:
Operating environment
1• 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.)

18
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.

Sucks and compresses the low-temperature,
low-pressure gas refrigerant produced in the
evaporator, to produce high-temperature,
high-pressure gas.
Conducts heat exchange between the high-temperature,
high-pressure gas refrigerant produced in the
compressor and the air, to produce high-temperature,
high-pressure liquid refrigerant.
Forcefully blows air to accelerate heat exchange
between the refrigerant in the condenser and the air.
The valve mechanism reduces pressure of the
high-temperature, high-pressure liquid refrigerant
produced in the condenser, to produce low-temperature,
low-pressure liquid/gas mixed refrigerant.
Runs the agitator.
Evaporates the low-temperature, low-pressure liquid
refrigerant produced in the electronic expansion valve
through heat exchange between the refrigerant and oil, to
produce low-temperature, low-pressure gas refrigerant.
Improves the cooling efficiency by agitating the liquid
in the tank.
Detects the controlled liquid temperature in the tank.

Mode changing operation
Normally, the key is used to shift between individual modes.
For special modes, you can change the mode by pressing several keys simultaneously for two seconds.
The control panel provides the following seven operation modes.
Among these seven modes, only four modes are available for normal operations.
In other modes, the Oil Cooling Unit may malfunction depending on operation.
Before using each mode, please understand the description on each mode.
Operation mode
 The factory setting is the “Operation lock” mode.
To start operation, cancel the operation lock mode.
(See page .)
 With the standard model, the initial operating conditions are as follows:

Checking Initial Operating Conditions
Turn ON the power supply for the Oil
Cooling Unit.
Is “U1” displayed on the control panel?
Check the initial operating conditions.
Changing operation settings
Is the “Operation lock” mode selected? Cancel the operation lock mode.
It means reverse-phase connection.
Exchange two phases out of three
phases (L1, L2 and L3).
(1) Operation mode display: Displays the operation mode.
(2) Data display: Displays the target temperature setting.
Check the current operation settings on the control panel display.
With the standard model, the factory setting of the operation mode is “3” (Room temperature tuning, Tank liquid
temperature control), and the temperature difference is “0.0 (K)”.
(With non-standard models, the factory settings may be different from the above.)
Holding constant tank liquid temperature
Tuning tank liquid temperature to room temperature (or machine temperature)
Cooling liquid in the tank at constant capacity (%)
Check the indication on the control panel.
The DAIKIN factory setting is the “Operation lock” mode.
∗1:
You hear tick sound after power-ON, while the electronic
expansion valve is under initial setup. This does not mean a
fault.
∗2: For initial setup of the electronic expansion valve and the
microprocessor, the Oil Cooling Unit takes 60 to 90 seconds.
After the initial setup, cooling operation starts (the compressor
runs).
∗The “Operation lock”
mode locks the Oil
Cooling Unit, and disables
any key operation other
than operation lock cancel.
If you keep pressing the and keys
simultaneously for two seconds, the Oil Cooling
Unit starts operation.
Keep pressing
these keys
simultaneously for
two seconds.
