SAFETY AND ADVISORY MESSAGES
1.
WARNING! Vertical radiators are
subject to wind effects and installation
should consider the potentially
dramatic effect of prevailing winds on
cooling system performance.
2.
CAUTION! Caution must be used
when city water make up lines are
connected to the cooling system. City
water supply pressure may exceed the
20 PSI maximum limit of the radiator.
3.
CAUTION! Piping to radiators
should be externally supported and
not hung on the radiator. Flexible
connections should be used when
piping to the radiator.
4.
DANGER! For radiators that
include fan, motors, etc.: before initial
startup, inspect the fan to make sure
the blade tips do not hit the shroud, fan
ring or fan guard. Also, inspect all
moving parts (such as fans, motors,
shafts, sheaves and belts) for damage
and/or loose bolts.
5.
DANGER! Failure to observe safety
precautions could cause personal injury
or equipment damage.
6.
DANGER! Do not operate without
guards. Turn off power to install or
service. Use approved lockout/tagout
procedures.
7.
DANGER! High voltage and
rotating parts may cause serious or fatal
injury.
8.
WARNING! Over-tensioning belts
shortens belt and bearing life. (See
Section IV. B. for correct belt tensioning)
9.
WARNING! Under-tensioning belts
can cause the following (See Section
IV. B. for correct belt tensioning):
− Premature belt wear
− Reduced radiator cooling
performance as a result of slower fan
speed
− Fan failure. Some types of fans may
have critical or resonant frequencies
that must be avoided.
10.
DANGER! Do not make any
changes to any fan drive components
that may change or vary the original
design fan speed. All fans have a
maximum safe operating speed and
some fans may have minimum and/or
resonance speeds that must be
considered. Consult with Rocore
engineering before considering, changing
or varying a fan’s speed.
11.
DANGER! Avoid extended exposure to
equipment with high noise levels.
12.
CAUTION! Do not overfill the
radiator or surge tank. As the system
heats up, the coolant will expand and hot
coolant or steam will be forced out of the
overflow hose. (See Section III. F. for
correct filling instructions)
13.
CAUTION! Check with engine
manufacturer to ensure that the coolant
used is compatible with their
requirements.
