Grease Trough and Curb Hinge Assemble For
Models PNU, PDU, USNU, and USDU
RECEIVING AND INSPECTION
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.
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 timbersthrough 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.
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.
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.
CAUTION! Provide fire extinguishers, or fire alarms,
or telephone 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 which is protected by a cardboard
carton.
c. Motors dismounted from fans.
d. Spare wheels or propellers.
e. The belts, sheaves, bushings and other parts
when not mounted on fan.
f. Boxes, bags or cartons of hardware.
g. Curbs
h. Shutters
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.
Store at least 3 ½” off the floor on wood 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.
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 at between 70°F and 105°F (wide
OUTDOOR: Fans designed for outdoor use may be
stored outdoors, if absolutely necessary. The storage
area should bereasonably 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 where 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.
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.
GREASE TROUGH INSTALLATION (Roof Fan)
1. Place grease trough assembly in position on curb
as shown in Figure A. The hole in the center of the
grease trough top should be directly under the

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
