INSTALLATION & MAINTENANCE INSTRUCTIONS

Windmaster Model DC

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 by the carrier. Re
port damage to the carrier within 15 days. Failure to report dam
age 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 to prevent damage.

STORAGE

Fans are protected against damageduring shipment. If theycan­not be installed and put into operation immediately upon receipt
certain precautions are necessarytopreventdeterioration 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 accesso
ries is indoors, above grade, in a low humidity atmosphere which
is sealed topreventthe entry 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 air in the storage
enclosure.

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 parts and 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 out
doors, if absolutely necessary. The storage area should be rea

­sonably 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 enoughblocking 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,ortominimizewateraccumula­tion. 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 propellersshould 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 partscoated 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 (AshlandOil 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. CAUTION! Guards must be installed when fan is within
reach of personnel or within eight (8) feet (2.5 m) ofworking
level or when deemed advisable for safety.

Installation With Slant Wall Housing

4. To install a fan mounted in a galvanized steel slant wall
housing when the wall thickness is 4" or less, provide a
rectangular opening inthe wall equal to dimension in Fig.1.
It is preferable to frame the opening with 2 x 4 material, or a
metal frame in metal building or greenhouses. When the
wall thickness is more than 4", the height of the rectangular
opening should be 1 inch less than the height shown in Fig.
1 and the opening should be slanted approximately 15° as
shown in Fig. 2. Note: If wall thickness is less than 4"
framed opening height can be reduced 1/4" for each inch
less than 4" thick.
