RE CEIVING AND IN SPEC TION
Immediately upon receipt of a shipment, carefully
inspect for damage and shortage. 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 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 by the carrier. Report damage to the carrier
within 15 days. Failure to report damage within the
above time limit will cause rejection of a claim.
HAN DLING
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 at 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.
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 orifices
of fan.
CAUTION! Do not lift by the fan hood. Fans with
special coatings or paints must be protected in handling
to prevent damage.
STOR AGE
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.
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 that is 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 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.
Page 2
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.
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.
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.
IN SPEC TION AND MAIN TE NANCE
DURING STOR AGE
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.
RE MOVING FROM STOR AGE
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.
IN STAL LA TION
1. This device is combined with units that have
rotating parts and safety precautions should be
exercised during installation, operation and
maintenance.
WINDMILLING: Even when the power supply is
locked out, fans may cause injury or damage if the
impeller is subject “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.
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.
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. CAUTION! Guards must be installed when fan is
within reach of personnel or within seven (7) feet
(2.134 m) of working level or when deemed
advisable for safety.
4. Place Combination Curb Adaptor (CCA) on the
roof curb so that the shorter curb is on top of the
supply duct and the taller curb is on top of the
exhaust duct. See Figures 1 and 2.
5. Install the filtered air supply fan on the shorter curb
of the CCA as shown in Figure 2. Installation
instructions for the filter air supply fan are
attached to the unit (Form No. 613100).

6. Install the duct extension per the attached
installation instructions. (Form No. 613100)
7. Install the exhaust fan (Upblast Centrifugal Roof
Exhauster, Belt Drive) on the taller curb so that the
down spout is perpendicular to the CCA. See
Figure 2. Installation instructions for the Upblast
Centrifugal Roof Exhauster, Belt Drive (Form No.
613115) are attached to the unit.

the taller curb on the same side as the down spout.
If an optional curb hinge is purchased, the curb
hinge will be mounted so that the fan will hinge on
the side opposite to the grease trough. See Figure
