RECEIVING AND INSPECTION

Immediately upon receipt of a shipment, carefully inspect for
damage and shortage. Turn the impeller by hand to see that
it turns freely and does not bind. If any damage and/or
shortage is detected or suspected, the carrier must be asked
to conduct an inspection. The consignee’s representative
should not accept a shipment without a notation on the
delivery receipt indicating items not delivered or the apparent
extent of damage.

When a shipment is opened and damage is found which was
not evident externally (concealed damage), it is mandatory
that the consignee request an immediate inspection by the
carrier. Report any damage to the carrier within 15 days.
Failure to report damage within the above time limit will
result in rejection of a claim.

HANDLING

When handling fans and their accessories, always use
equipment and methods that will not cause damage. Fans
should be lifted using slings and padding or spreaders to
avoid damage.

CAUTION! Always make sure that all lifting and handling
equipment and techniques conform to current safety
standards.

Avoid lifting fans in a way that will bend or distort fan parts.
Never pass slings or timbers through the fan orifice.

CAUTION! Do not lift by the fan hood. Fans with special
coatings or paints must be protected in handling to prevent
damage.

FORM 610032

CAUTION! Provide fire extinguishers, or fire alarms, or
emergency response communication to protect building and
equipment against fire damage. Be sure that building and
storage practices meet all local, state and federal fire and
safety codes.

The following fans or accessories must be stored indoors, in
a clean dry atmosphere:

a. Propeller wall fans not in wall housings.
b. Any fan protected by a cardboard carton.
c. Motors dismounted from fans.
d. Spare wheels or propellers.
e. Belts, sheaves, bushings and other parts when not

mounted on fan.

f. Boxes, bags or cartons of hardware.
g. Curbs
h. Dampers

Remove any accumulations of dirt, water, ice or snow and
wipe dry before moving to indoor storage. Allow cold parts
to reach room temperature to avoid “sweating” of metal
parts. Open boxes or cartons. Remove any accumulated
moisture; if necessary use portable electric heaters to dry
parts and packages. Leave coverings loose to permit air
circulation and to permit periodic inspection.

Rotate wheels or propellers by hand to distribute bearing
grease over the entire bearing surfaces.

Store at least 3 ½” off the floor on wooden blocks covered
with moisture proof paper or polyethylene sheathing.
Provide aisles between parts and along all walls, to permit
air circulation and space for inspection.

STORAGE

Fans are protected against damage during shipment. If they
cannot be installed and put into operation immediately upon
receipt certain precautions are necessary to prevent
deterioration during storage. Responsibility for integrity of
fans and accessories during storage must be assumed by
the user. The manufacturer will not be responsible for
damage during storage. These suggestions are provided
solely as a convenience to the user, who shall make his own
decision as to whether to use any or all of them.

INDOOR: The ideal storage environment for fans and
accessories is indoors, above grade, in a low humidity
atmosphere which is sealed to prevent the entry of blowing
dust, rain, or snow. Temperatures should be evenly
maintained between 70°F and 105°F (wide temperature
swings may cause condensation and "sweating" of metal
parts). Windows should be covered to prevent temperature
variations caused by sunlight. Provide thermometers and
humidity indicators at several points and maintain the
atmosphere at 40% relative humidity, or lower.

It may be necessary to use trays of renewable desiccant or
portable dehumidifier to remove moisture from the air in the
storage enclosure.

Thermostatically controlled portable heaters (vented to
outdoors) may be required to maintain even temperatures
inside the enclosure.

OUTDOOR: Fans designed for outdoor use may be stored
outdoors, if absolutely necessary. The storage area should
be reasonably level and drained or ditched to prevent
accumulation of water. Fencing and lighting for security are
desirable. Roads or aisles for portable cranes and hauling
equipment are needed. Consider the use of drift fencing to
minimize accumulation of blowing snow or dirt.

The following fans may be stored outdoors, if dry indoor
storage space is not available:

a. Fans intended for outdoor use that are crated in wood.
b. Wall fans installed in wall housings.

All fans must be supported on wooden blocks or timbers
above water or normal snow levels. Provide enough
blocking to prevent settling into soft ground. Fans should be
set in place using the directional arrow markings on the crate
as a guide.

Locate pieces far enough apart to permit air circulation,
sunlight, and space for periodic inspection. Place all parts
on their supports so that rain water will run off, or to minimize
water accumulation. Do not cover parts with plastic film or
tarps-these cause condensation of moisture from the air
passing through heating and cooling cycles.

Fan wheels and propellers should be blocked to prevent
spinning caused by strong winds.

INSPECTION AND MAINTENANCE

DURING STORAGE

Inspect fans and accessories at least once per month, while
in storage. Log results of inspection and maintenance
performed. A typical log entry should include the following:

a. Date
b. Inspector’s Name
c. Name of Fan
d. Location
e. Condition of Paint or Coating

f. Is moisture present?
g. Is dirt accumulated?
h. Corrective steps taken?

If moisture or dirt accumulations are found on parts, the
source should be located and eliminated. Fans should be
rotated at each inspection by hand ten to fifteen revolutions
to redistribute the motor and bearing lubricant.

If paint deterioration begins, consideration should be given to
touch-up or repainting. Fans with special coatings may
require special techniques for touch-up or repair.

Machined parts coated with rust preventive should be
restored to good condition promptly if signs of rust occur.
The most critical items are pulleys, shafts and bearing
locking collars. At the first sign of rusting on any of the
above parts, remove the original rust preventive coating with
petroleum solvent and clean lint-free cloths. Polish any
remaining rust from surfaces with crocus cloth or fine emery
paper and oil. Do not destroy the continuity of the surfaces.
Wipe clean with lint-free cloths and recoat surfaces evenly
and thoroughly with Tectly 506 (Ashland Oil Company) or
equal. For hard to reach internal surfaces or for occasional
use, consider using Tectly 511M Rust Preventive or WD40 or
equal.

REMOVING FROM STORAGE

As fans are removed from storage to be installed in their final
location, they should be protected and maintained in similar
fashion, until the fan equipment goes into operation.

INSTALLATION

1. CAUTION! This unit has rotating parts and safety

precautions should be exercised during installation,
operation and maintenance.

2. WARNING! DO NOT use in HAZARDOUS

ENVIRONMENTS where fan’s electrical system could
provide ignition to combustible or flammable materials,
unless unit is specifically built for hazardous
environments.

3. MOUNTING The fan should be mounted on a solid

foundation equipped with anchoring devices (such as
anchor bolts). Level the fan on the foundation,
shimming where necessary. Anchor the fan securely to
the foundation. If vibration isolators are used, these
should be installed between the fan and the foundation.
When mounted on suspended platforms, adequate
cross bracing will be required. Flexible connections at
the inlet and/or outlet are recommended.

5. CAUTION! Before proceeding, make sure electrical

service to fan is locked in “OFF” position. All wiring
should be in accordance with local ordinances and the
National Electric Code.

(a) Check voltage at the fan to assure it corresponds

with motor nameplate; high or low voltage can
seriously damage the motor. Extra care should be
taken when wiring two speed motors to assure
proper motor lead groupings are used since
improper connections WILL damage motors and
void motor warranty.

(b) Apply power momentarily to check impeller rotation

with directional arrow. In the case of three phase
motors, the direction can be reversed by
interchanging any two of the three motor leads. For
single phase motors, the reversing instructions
appear on the wiring diagram located on the motor.
WARNING! Operation in the wrong direction will
deliver a reduced amount of air.

6. OUTDOORS FCF units are provided with standard

Weather Covers (Arr. 10). Outlet shutters attached to
the fan discharge should be normally closed when the
fan is not running.

7. BELT GUARDS (Weather covers also serve as belt

guards) must be installed when fan is within reach of
personnel or located within 7 feet (2.134 m) of working
level or when deemed advisable for safety.

8. INLET, OUTLET GUARDS (Available from Acme as

optional equipment) must be installed whenever the fan
is installed without ducts attached to the fan inlet and/or
outlet and is within seven (7) feet (2.134 m) of working
level or when deemed advisable for safety.

9. DISCHARGE POSITION ROTATION - FCF SERIES

(ARR. 10) Remove motor enclosure cabinet cover and
lay unit down on intake collar. (Figure 2)

Remove 8 bolts and rotate motor compartment to
desired position (Figure 3) and replace 8 bolts in new

position. FCF housing is rotatable in 45° increments.
The FCA and FCE housing is rotatable in 90°

increments by changing the location of the feet.

4. BELT DRIVES Check pulley alignment and belt

tension. Belt should deflect .50" (13 mm) to .75" (19 mm)
when depressed by hand midway between pulleys. A
belt should be just tight enough to avoid slippage.
When the motor and drives are received mounted to
the (FCF) fan, the RPM has been set to meet the
specified performance. Motor positions for the FCD,
FCH and FCJ blowers are defined in Figure 1.

For fans shipped without motors and drives mounted,
the RPM is set by the installer as specified. Pulley
combinations and belt lengths are included with each
blower.
