REVERSIBLE FANS
! CAUTION ! ! CAUTION ! ! CAUTION !
BEFORE STARTING THE MACHINE CHECK THE
FOLLOWING:
1. CHECK THE AIR TUBE INLET on the front of the
fan to ensure that it has proper amount of clearance
to allow for a non restricted rotation of the fan
blades during the pitch change of the fan from
Cooling Mode into Cleaning Mode. This can be
done with the fan belt still loose. Use the shop air to
turn the fan blades into the cleaning mode position.
Slowly release the air from the fan hub until the fan
blades are exactly half way back to the cooling
mode. With the fan blades in this mid position,
rotate the fan blades and makes sure that there is at
least 5/8” (15-mm) clearance between the air tube
inlet and the base of the fan blades (maximum width
of blades). If the clearance is less than 5/8” (15-
mm) remove the fan from the mounting flange and
bend the air tube assembly to provide the clearance
required. NOTE: THE AIR TUBE INLET MAY
BECOME BENT DURING SHIPPING AND WILL
NEED TO BE EXAMINED BEFORE
INSTALLATION TO ENSURE THAT CLEARANCE
IS AVAILABLE. PLACE THE DRAWING OF THE
AIR TUBE INLET ON TOP OF THE FAN HUB AND
CHECK TO SEE THAT THE AIR TUBE MATCHES
THE PROFILE OF THE DRAWING.
2. MAKE SURE ALL ELECTRICAL WIRES,
RADIATOR OVERFLOW TUBES, HYDRAULIC
HOSES, ETC. are firmly secured with tie straps and
cannot come in contact with the Cleanfix
®
Fan or
operating area.
3. MAKE SURE THE AIR TUBE SUPPLY LINE is
secured where it enters into the fan shroud. It
should not be possible for additional lengths of air
tube to enter into the fan shroud where it can be
sucked into the rotating fan. If necessary, clamp or
tie strap the air supply tube to the shroud.
4. MAKE SURE THAT THE COMPRESSION
FITTING IS INSTALLED CORRECTLY onto the
steel air tube inlet by giving it a strong pull. The
compression fitting when installed correctly will not
come back off of the air tube inlet because the steel
ring inside the compression fitting will bite into the
steel tube. ALSO, CHECK TO ENSURE THAT
THE BRASS TUBE INSERT was installed in the air
tube supply line where it connects into the opposite
side of the compression fitting. If the tube support is
not used, the air supply tube will not stay inside the
compression fitting and may become entangled in
the rotating fan during operation.
5. MAKE SURE ALL TOOLS HAVE BEEN
REMOVED from engine compartment including the
topside of the radiator and inside of the shroud
before the fan guards are installed. Obstacles in the
path of rotation can interfere with the movement of
the fan and can result is damage to the fan blades,
fan hub and/or the radiator core.
6. CHECK THE WATER PUMP BEARING OR FAN
MOUNTING BEARING. Check to ensure that this
bearing is in good condition. If the bearing does not
turn freely or if there is transverse movement of the
bearing, it should be replaced before the Cleanfix
®
Fan is installed to prevent any out of balance of the
fan during operation.
7. CHECK THE RADIATOR MOUNTING BOLTS
AND SHROUD MOUNTING BOLTS to ensure that
the radiator and shroud are firmly secured and
unable to move during the operation of the machine.
Loose shroud bolts can allow the fan shroud to
move into the path of the rotating blades and loose
radiator mounting bolts can allow the radiator to flex
in position allowing the shroud to come into contact
with the rotating fan blades.
8. MAKE SURE ALL FAN GUARDS HAVE BEEN
INSTALLED and firmly secured into place. The
Cleanfix
®
Reversible fan creates a lot of airflow in
both the cooling and cleaning mode operation. The
result of this airflow is a strong vacuum effect that
can suck items/obstacles that are located inside or
around the engine compartment or fan.
9. CHECK TO ENSURE THE CONTROL BOX IS
CONNECTED TO A DEDICATED (SEPARATE)
POWER SOURCE and correct amperage & voltage
is available. (9-11 amps 24-volt sys., 16-18 amps
12-volt sys.)
