1. Parts List

When lifting a Belt Drive unit onto the roof, use either

the four lifting points on the drive frame or the two lifting

points on the bearing plate if present, see Figure 2 for

lifting points. Access to the drive frame is accomplished

by removing the screws pointed out in Figure 3. The

cover can then be removed and placed on a ﬂat surface

in an area protected from strong winds.

When the Direct and/or Belt Drive unit is on the roof,

move fan to desired location using lifting points and

fasten securely through mounting holes in base. Shims

may be necessary depending upon rooﬁng material

thickness.

The motor amperage and voltage ratings must be

checked for compatibility to supply voltage prior to

ﬁnal electrical connection. For Direct and/or Belt Drive

installations, the electrical supply should be routed

through the conduit chase located between the curb

cap and the bottom of the motor compartment or

through the breather tube. Wiring must conform to local

and national codes.

Storage

Fans are protected against damage during shipment.

If the unit cannot be installed and operated immediately,

precautions need to be taken to prevent deterioration of

the unit during storage. The user assumes responsibility

of the fan and accessories while in storage. The

manufacturer will not be responsible for damage

during storage. These suggestions are provided solely

as a convenience to the user.

Indoor

The ideal environment for the storage of 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 30° to 110°F (-1° to 43°C)

(wide temperature swings may cause condensation

and "sweating" of metal parts). All accessories must be

stored indoors in a clean, dry atmosphere. Remove any

accumulations of dirt, water, ice or snow and wipe dry

before moving to indoor storage. To avoid "sweating" of

metal parts, allow cold parts to reach room temperature.

To dry parts and packages, use a portable electric

heater to get rid of any moisture buildup. Leave

coverings loose to permit air circulation and to allow for

periodic inspection.

The unit should be stored at least 3½ inches (89 mm)

off the ﬂoor on wooden blocks covered with moisture

proof paper or polyethylene sheathing. Aisles between

parts and along all walls should be provided to permit

air circulation and space for inspection.

Outdoor

Fans designed for outdoor applications may be stored

outdoors, if absolutely necessary. Roads or aisles for

portable cranes and hauling equipment are needed.

The fan should be placed on a level surface to prevent

water from leaking into the fan. The fan should be

elevated on an adequate number of wooden blocks so

that it is above water and snow levels and has enough

blocking to prevent it from settling into soft ground.

Locate parts far enough apart to permit air circulation,

sunlight and space for periodic inspection. To minimize

water accumulation, place all fan parts on blocking

supports so that rain water will run off.

Do not cover parts with plastic ﬁlm or tarps as these

cause condensation of moisture from the air passing

through heating and cooling cycles.

Fan wheels should be blocked to prevent spinning

caused by strong winds.

Inspection and Maintenance

During Storage

While in storage, inspect fans once per month. Keep a

record of inspection and maintenance performed.

If moisture or dirt accumulations are found on parts,

the source should be located and eliminated. At each

inspection, rotate the wheel by hand ten to ﬁfteen

revolutions to distribute lubricant in motor. 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. Immediately remove the original rust preventive

coating with petroleum solvent and clean with lint-free

cloths. Polish any remaining rust from surface with

crocus cloth or ﬁne emery paper and oil. Do not destroy

the continuity of the surfaces. Thoroughly wipe clean

with Tectyl

506 (Ashland Inc.) or the equivalent. For

hard to reach internal surfaces or for occasional use,

consider using Tectyl

511M Rust Preventive, WD-40

or the equivalent.

Removing From Storage

As fans are removed from storage to be installed in

their ﬁnal location, they should be protected and

maintained in a similar fashion until the fan equipment

goes into operation.

IMPORTANT

Installation, troubleshooting and parts replacement

are to be performed only by qualified personnel.

Consult and follow all applicable national, state and

local codes. They will supercede this document.
