RECEIVING AND INSPECTION

Immediately upon receipt of a shipment, carefully inspect for
damage and shortage. Turn propeller by hand to see that it turns
freely and does not bind. If any damage and/or shortage is de
tected or suspected the carrier must be asked to conduct an in
spection. The consignee’s representative should not accept
shipment without a notation on the delivery receipt indicating
items not delivered or 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 bythe carrier. Report
damage to the carrier within 15 days. Failure to report damage
within the above time limit will cause rejection of a claim.

HANDLING

When handling fans and their accessories, always use equip
ment 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 equip
ment 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 orifices of fan.

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

STORAGE

Fans are protected against damage during shipment. If theycan­not 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 sugges
tions 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 accesso
ries is indoors, above grade, in a low humidity atmosphere which
is sealed toprevent theentry of blowing dust, rain, or snow. Tem
peratures should be evenly maintained at between 70°F and
105°F (wide temperature swings may cause condensation and
"sweating" of metal parts). Windows should be covered to pre
vent temperature variations caused by sunlight. Provide ther
mometers 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 porta
ble dehumidifier to remove moisture from the airin the storage en
closure.

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

CAUTION! Provide fire extinguishers, or fire alarms, or emer
gency response communication to protect building and equip
ment 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 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 partsand packages. Leave cover
ings loose to permit air circulation and to permit periodic inspec
tion.

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.

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 di
rectional 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 sup
ports so that rain waterwill run off, or to minimizewater accumula
tion. 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 lo
cation, they should be protected and maintained in similar fash
ion, 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 fans in hazardous environments
where the fan’s electrical system could provide ignition to
combustible or flammable materials, unless the unit is
specifically built for that hazardous environment.

3. WARNING! If gases, other than clean air, are to be
exhausted using the fan, then the user bears the
responsibility of determining that the fan is appropriate and
safe for the application.

12. Continue with Step 16.

INSTALLATION OF FAN WITHOUT HOUSING OR CRATE

13. To install fan, provide a square opening in the wall equal to
the outside dimensions of thefan. It ispreferable to frame in
the opening with 2 x 4 material, or a metal frame in metal
buildings.

14. Slide the fan into the framed opening in the wall, with the
motor in the position shown in Fig. 6. Securely fasten with
bolts or screws provided by the installer.

15. Fans mounted with damper require a different wall opening
(W.O.) size than those mounted in Acme's collars or wall
housings. Propeller-to-damper distance (M) is important to
reduce turbulence and damper flutter which may lead to
premature damper failure. See Figure 7.

16. A distance of at leastone and one-half times the diameterof
the fan should be allowed between the faninlet or discharge
opening and any adjacent wall or large obstruction.

17. CAUTION! Before proceeding, make sure electrical
service to fan is locked in “OFF” position.

18. All wiring should be in accordance with local ordinances
and the National Electric code.

19. Before starting, check all fasteners for tightness particularly
in the propeller hub. Turn the propeller by hand to make
sure it rotates freely and that the blades do not strike the
orifice.

20. WARNING! Check voltage being supplied to the fan to see
that it corresponds with the motor nameplate voltage; high
or low voltage can seriously damage the motor. On
multi-voltage motors, check motor terminal connections to
make sure motor is internally connected for voltage being
supplied. Motor wiring diagram is located on the side of the
motor or in the motor wiring compartment. Extra care
should be taken when wiring two speed motors since
improper connections will damage motor and void motor
warranty. Leave enough slack in wiring to allow for motor
movement when adjusting belt tension.

21. Apply power momentarily and compare the rotation of the
impeller with the directional arrow on fan. In the case of
three phase motors, the direction can be changed by
interchanging any two of the three motor leads. In the case
of the single phase motors, the reversing instructions will
appear on the wiring diagram in the motor wiring
compartment.

22. When supply type fans are used with motorized wall
dampers, it is necessary that a time delay switch be used
between the power source and the fan motor which will
allow the damper to fully open before the fan is activated.

MAINTENANCE

1. Under normal usage, no spare parts are recommended for
one year normal service. Recommended spare parts are
shown on page 5.

2. CAUTION! Before proceeding, make sure electrical
service to fan is locked in “OFF” position.

WINDMILLING: Even when the power supply is locked
out, fans may cause injury or damage if the impeller is
subject to “windmilling” which is the turning of the impeller
and drive components due to a draft in the system. To
guard against this hazard, the impeller should be secured
to physically restrict rotational movement.

3. Motor bearings are prelubricated. Consult information
printed on motor for lubrication instructions.

4. Propeller shaft bearings are prelubricated, sealed and
require no service.

5. On belt driven units, check belt tension afterfirst 48 hours of
operation and thereafter annually. Belt should depress its
width when pressed firmly inward at midway point between
the pulleys. Too much tension will damage bearings. The
belt should be tight enough to prevent slippage. When
replacing worn belt, replace motor pulley if “shoulder” is
worn in groove. WARNING! Do not operate at higher
speeds than that cataloged for this equipment. Do not
replace motor pulley with a larger diameter pulley. Do not
replace the fan pulley with one smaller in diameter. The
pulley ratios areset so that themotor will not be overloaded.

6. If motor requires replacement, a comparable one to the
original withthe same service factor and enclosure must be
used.

7. If propeller shaft bearing need replacement, replace with
bearings comparable to original equipment. For die formed
type support housing install new bearings into neoprene
rings, check correct position of propeller with orifice,
position bearings in die formed recess and tighten set
screws. Replace die formed bearing cap and tighten four
bolts.

NOTE: If locking collar type bearing is used,collar must first
be positioned against inner race on bearing nearest
propeller and turned in direction of propeller rotation with
drift pin and hammer until it locks. Locking collars must be
on inboard (facing) sides of the bearing. Secure bearing to
shaft with set screw.Lock and secure other bearing to shaft
in same manner.
