Before handling this unit, be sure to turn OFF the
power supply.
Handling this unit in live conditions may result in
electric shock.
DANGER
Precautions for use
Before handling this unit, turn OFF the power supply.
Do not operate the Oil Cooling Unit with the unit
casing or terminal covers of the motor or other
electric parts removed. Failure to observe this
instruction may result in electric shock.
Do not operate the unit with the covers opened.
Do not use this unit in any condition other than
those specified in the catalog or delivery
specifications. Failure to observe this instruction
may result in a serious accident, such as damage
to the main machine, injury, fire and electric shock.
Do not use the unit beyond specified operating conditions.
Do not modify this unit.
Any person other than DAIKIN authorized service personnel must
not disassemble or repair this unit. Failure to observe this
instruction causes fire, electric shock or injury.
If this unit is disassembled, repaired or modified by an
unauthorized person, it shall not be beyond the scope of warranty.
Do not disassemble or repair the unit.
During operation, the external panel may
become extremely hot. Be careful that your hand
or body does not directly touch it. Otherwise, you
may get a burn.
Keep your hand or body away from the unit during operation.
Do not immerse this unit in water, or splash
water on the unit. Failure to observe this
instruction may result in short-circuit or electric
shock.
Do not splash water.
During this period, electric discharge from the
internal high-voltage parts (capacitors) has not
been completed. Failure to observe this instruction
may result in electric shock.
Dot not handle the unit for 5 minutes after power supply is turned OFF.
Do not install this unit in a place where evolution,
inflow, retention or leak of inflammable gas may be
expected, or where airborne carbon fiber is present.
Failure to observe this instruction causes fire.
Do not use the unit in explosive atmosphere.
The Oil Cooling Unit is not equipped with a
circuit breaker. A circuit breaker exclusively for
the Oil Cooling Unit should be provided by user.
To ensure safety, it is recommended to use an
earth leakage breaker. To use an earth leakage
breaker, select an inverter-compatible type.
(Recommended: 15 mA or 20 mA)
CAUTION
Prepare a circuit breaker at user’s site.
If the oil pump operation system has a fault, oil
cannot be supplied to the main machine. Normally
in this case, the Oil Cooling Unit detects the fault
and outputs an alarm signal. However, it may not
be detected depending on the fault mode. If the
main machine must be protected even in such a
case, provide a flow switch for the oil flow path of
the main machine to watch the oil flow.
Provide a flow switch for the main machine.
Before or immediately after connection of the Oil Cooling Unit, make sure that the oil piping of the main machine is not
blocked (fully closed). If the unit is operated with the oil piping blocked (fully closed), the oil hose may break due to an
oil temperature rise, causing oil to flow out of the Oil Cooling Unit. When the oil temperature abnormally rises, the FE or
FH alarm is activated. In this case, stop operation of the main machine as soon as possible.
Check the oil piping.
The optional CE model (AKZ
∗∗
8–C) Oil Cooling Unit
is classified as an auxiliary machine of the main
machine (Overvoltage Category
II ). It has been
self-declared under the following conditions. Be sure
to follow the specifications of the main machine.
(1) Provide a main power supply circuit breaker for
the main machine according to the EN60204-1
requirement.
(2) Connect the power supply via a transformer
with basic insulation rating
∗
.
∗
Basic insulation: Insulation provided for live parts
to ensure fundamental protection against electric
shock (under IEC Standard 60335-1)
Precaution for using the CE model (optional)
During transportation (including storage), do not
tilt the Oil Cooling Unit more than 30˚.
If the unit is tilted more than 30˚, the compressor
may have a fault.
Do not tilt the unit.
