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 only.
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 ENVIRONM
ENT 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 at (on/off) switch located on side of unit or unplug Fan from power supply.

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.
