1. General
■ 1-3. Safety precautions
DANGER
● Shut off the power when undertaking construction of the equipment (installation, piping and wiring).
Fire, electric shock or injury may be caused due to a short circuit.
● Do not machine, disassemble or modify the product. An accident, fire, electric shock, electronic part mage or burnout may
be caused. If the product has been modified, we cannot take charge of repair.
WARNING
● Do not use the product when it is faulty. An accident such as electric shock and fire may be caused.
Stop the operation at once and repair the product.
● This machine is not provided with a power switch for the primary power supply.
Be sure to install a power switch at the power supply source.
● Do not leave the product in a subzero environment in the status where sample water or fresh water remains in the sample
water detection tube. The sample water detection tube will be broken by freezing, resulting in a failure.
● Never feed water contaminated with oil or impurities directly into the detection tube in the sensor unit. Since this machine
is a precision equipment, a malfunction or impossibility of measurement may be caused by contaminated detection tube.
● Please use the battery properly without making mistakes in terms of orientation of polarity.
Equipment might break down or be heated which leads to ignition.
CAUTION
●
Never use the operational log memory card of this oil concentration detector (FOCAS-2000) for the existing oil
concentration detector (FOCAS-1800). If used, its data will be lost. We cannot assure and recover any operational log
data lost by the use in the existing oil concentration detector. By the way, FOCAS-2000 can read the operational log
memory card of FOCAS-1800.
