MAINTENANCE
DANGER
ALWAYS SHUT OFF THE FAN AND UNPLUG IT FROM ITS POWER SOURCE TO PREVENT ACCIDENTAL STARTING AND
THE POSSIBILITY OF ELECTRICAL SHOCK AND/OR ELECTROCUTION. BE SURE THE FAN BLADE HAS STOPPED
ROTATING BEFORE PLACING ANY OBJECTS OR FINGERS NEAR THE FAN GRILL.
I. Visually check all fasteners and individual components for loose or broken parts. Tighten or replace items as required, with
genuine, factory approved replacement parts.
2. Keep the fan blade clean from debris. Accumulation of dust, dirt, paint, etc. on the fan blade will throw the blade rotation out of
balance resulting in damage. To clean the fan blade, be sure the plug is disconnected and the blade has stopped rotating.
Remove one grill and wipe blade and interior shell housing clean of debris with a damp cloth and mild liquid soap. Dry all parts
thoroughly.
DO NOT PRESSURE WASH THE FAN. Replace grill prior to next operation.
DANGER
DO NOT OPERATE THE FAN WITHOUT THE INLET AND OUTLET GRILL PROPERLY IN PLACE.
3. Contact Schaefer directly for fan maintenance or repair not described in this manual (or if you are unsure whether maintenance is
required.) at Tel# (320) 251-8696 or at www.schaeferfan.com.

SAFETY PRECAUTIONS
DANGER
THE FAN IS DESIGNED FOR PORTABLE AIR VENTILATION PURPOSES ONLY. THE FAN IS NOT DESIGNED FOR TRANSPORTING LIQUID OR SEMI-SOLID MATERIALS. THE ELECTRIC MOTOR AND FAN HOUSING ARE NOT DESIGNED FOR
OPERATION IN AN EXPLOSIVE OR FLAMMABLE ATMOSPHERE. OPERATION OF THE FAN IN AN EXPLOSIVE OR FLAMMABLE ATMOSPHERE MAY RESULT IN PROPERTY DAMAGE, PERSONAL INJURY OR EVEN DEATH. INCORRECT USE
OF THE FAN CAN RESULT IN AN ELECTRICAL SHOCK AND/OR ELECTROCUTION. ALWAYS OPERATE THE FAN IN
COMPLIANCE WITH CURRENT OSHA AND NATIONAL ELECTRIC CODE REGULATIONS.
DANGER
INCORRECT USE OF THE FAN CAN RESULT IN PROPERTY DAMAGE, PERSONAL INJURY OR EVEN DEATH. TO REDUCE
THIS RISK, GIVE COMPLETE AND UNDIVIDED ATTENTION TO THE JOB AT HAND. AN ENVIRONMENT ATMOSPHERE
CONSTANTLY CHANGES. THEREFORE, IT'S RECOMMENDED THAT AIR MONITORING/ GAS DETECTION EQUIPMENT BE
USED FREQUENTLY. IF TESTS SHOW THAT THE ATMOSPHERE QUALIFIES AS A HAZARDOUS LOCATION (AN AREA
WHERE THE POSSIBILITY OF EXPLOSION AND FIRE IS CREATED BY THE PRESENCE OF COMBUSTIBLE LIQUIDS,
FLAMMABLE GASES, VAPORS, DUST, FIBERS, FLAMES OR FILINGS.) DO NOT USE THIS FAN. READ AND UNDERSTAND
THE FOLLOWING PREPARATION ITEMS AND GENERAL SAFETY INFORMATION.
PREPARATION
1) Become familiar with the fan operations before utilizing this fan. Read and understand all cautions and warnings in this
manual. Refer to current OSHA publications for complete job safety and health rules and regulations (CFR 1926 and 1910).
2) Confirm that the fan is in its original, factory configuration and has not been modified in any manner.
3) Minors should not be allowed to operate the fan. Close attention is necessary when used, especially when used near children
or animals.
4) Guard against the possibility of back-related injuries. Always lift the fan with leg muscles and not with the back.
5) Periodically inspect the fan visually for damaged or worn parts. Check for loose and/or broken parts. Be sure that the fan and
accessories are in good working condition before operating.
6) Ground the motor securely. The (U.S.) fan utilizes a NEMA 5-15P plug. It is designed to operate ONLY from a grounded, 115
volt nominal AC~, 60Hz, single phase power source that utilizes a NEMA 5-15R receptacle. The 230 volt, 50Hz Fan
(VAF3000B) comes with a power cord having no end connector. The customer must provide a plug suitable for use with
grounded receptacles at their location. The use of a ground fault circuit interrupter (GFCI) gives additional on the job
protection from electrical shock hazards caused by ground faults in commercial, industrial and residential applications.
7) Know how to stop the fan quickly in an emergency. Turn unit off using (on/off) switch located on side of unit or unplug fan from
power supply.
GENERAL SAFETY INFORMATION
1) Never place the fan in standing water because of extreme shock hazard.
2) Never allow air intake grill to become blocked.
3) Never discharge flammable solvents or kerosene based chemicals through the fan air intake grill.
4) Do not use the fan in areas where flammable or combustible liquids, gases, vapors, dust, fibers or filings may be
present.
5) Never put any object in the air intake grill.
6) Never run the fan outside when it is raining. Never store the fan outdoors.
7) Do not use the fan as a toy.
8) Use the fan only with a properly grounded outlet.
9) Unplug the fan from outlet when not in use and before servicing.
WARNING: To reduce the risk of fire or electric shock, do not use this fan with any solid state speed control device.
GENERAL SAFETY INFO. (Continued)
10) Do not use the fan with a damaged cord or plug. Do not pull or carry the fan by its cord, do not use cord as a handle, do
not close a door on the cord and do not pull cord around sharp edges or corners. Keep cord away from heated surfaces. Do
not unplug the Fan by pulling on cord. Grasp the plug when unplugging. Do not handle the plug or cord with wet hands.
11) Keep hair, loose clothing, fingers and all parts of the body away from the air intake grill.
12) Do not allow water inside the motor. If the motor becomes wet for any reason, unplug the fan and thoroughly dry it before
using again.
13) Never remove the ground from the power cord or plug as this may result in electrical shock or electrocution.
Removing the ground would void the warranty.
14) If the fan has been dropped, left outdoors or dropped into water, etc., please thoroughly inspect it prior to use.
If the fan is not working or if you have a question about its safe operation, do not operate it. Contact Schaefer
Ventilation directly at (320)251-8696 or at www.schaeferfan.com.
OPERATION
1) Your new fan comes to you completely assembled and ready to operate. Upon removing the fan from its carton, inspect it
for any possible damage in transit.
2) Before operating the fan, please read all the safety precautions and general safety information about the proper and safe
use of the fan.
3) Assess your job site. Certain job site locations are classified as being hazardous because the atmosphere may contain gas,
vapor or dust in explosive quantities.
DANGER
THE ELECTRIC MOTOR AND FAN HOUSING ARE NOT DESIGNED FOR OPERATION IN AN EXPLOSIVE AND/OR
FLAMMABLE ATMOSPHERE OF ANY CLASS OR GROUP. OPERATION OF THE FAN IN AN
EXPLOSIVE OR FLAMMABLE ATMOSPHERE MAY RESULT IN PERSONAL INJURY OR DEATH.
4) Locate a properly grounded outlet.
5) Prior to plugging in the fan into a grounded outlet, inspect the inlet and outlet grills and remove debris which may restrict
airflow movement. Never operate the fan without the inlet and outlet grills properly secured and in place. Never replace the
grills with other than factory supplied replacement units.
6) Note the directional airflow indicator on the external shell. This is the way the air moves.
7) Place the fan on secure footing to prevent it from shifting while in use.
8) Do not stand directly in front of and/or face the fan outlet. Personal injury can result from
being struck by debris thrown at a relatively high velocity from the fan blade.
9) When ducting is required, do not install duct while fan is in operation. Place duct lip over
the Fan duct adapter, secure firmly and note direction of the airflow.
10) When duct is used, be aware that the airflow rate decreases as the length of duct increases. Airflow rates will vary with
specific duct types and manufactures.
11 ) Position fan air inlet away from walls and other obstructions to allow for maximum air intake.
12) For safe operation, use the fan only in combination with thorough gas detection tests and continual retesting.
DANGER
ALWAYS ASSUME A CONFINED SPACE WORK AREA IS CONTAMINATED UNTIL IT HAS BEEN PROVEN SAFE FOR
WORK PERSONNEL. NEVER ENTER A CONFINED SPACE WORK AREA UNTIL IT HAS BEEN THOROUGHLY TESTED
WITH APPROPRIATE GAS DETECTION EQUIPMENT AND PROVEN SAFE FOR WORK PERSONNEL.
