3.2 Conditions of Unit Installation
Exhaust gas from the engine is poisonous, and it could cause
casualties when it is inhaled.
Avoid using the machine in an insufficiently ventilated building
or a tunnel. When the machine is unavoidably used in such
insufficiently ventilated place, ventilation devices and ventilation
pipe should be provided for better ventilation.
PC002
In case that the unit is installed indoors for
operation, suction air port and exhaust fume outlet
port should be provided for better air ventilation.
Make sure to secure enough space in front of air
suction port and also to secure it after exhaust
fume outlet port so that the engine may not get
overheated.
Exhaust fume pipe extension should be provided
to send exhaust fume out of the installation place.
In case that the unit is installed inside any
tunnel, make sure to provide fresh air and
ventilate it.
In this case, make sure to extend the
exhaust fume pipe outdoors, and also make
sure to prevent any leak from any
connection pipes. In case that the unit is
operated under exhaust air pressure, make
sure to install the exhaust pipe to be
supported.
