When draining water from the water
separator, always use a container
which is suitable for the water
quantity.
* Otherwise, the drained water will overflow from
the container, which may flow outside of the
facility.
* The water drained into the container is
contaminated with waste oil. Discard the water
in accordance with the local laws and
regulations as well as the manufacturer's SDS.
Drain water properly from the water
separator.
* If draining the water separator is insufficient,
water may enter into the fuel system, which
causes damage to the devices.
Open the inlet valve of the water
separator slowly to prevent fuel in the
water separator from spilling out.
Wrap a cloth around the water
separator.
* Otherwise, spilled fuel may ignite and cause a
fire.
Tighten the cover and cock on the
water separator appropriately.
* Fuel leaks due to the tightening torque being
loose may cause a fire or fuel flow-out, which
results in environmental pollution.
