1. Breakage or Damage During Shipment
The transportation company is fully responsible for all shipping damage and will resolve problems promptly if you handle it
correctly. Please read these instructions carefully.
Examine the contents of all shipping cases. If you find any damage, call your transportation agent at once and have them make a
description on the freight or express bill describing the damage and the number of pieces. Then write us and we will send you
the original bill of lading. Get a claim blank from the express or truck company. Fill the claim form out. Attach the claim blank
to the original bill of lading together with a copy of our invoice. Attach a memo on which you show the value of the damaged
goods. Mail or hand these papers to your local transportation agent. They will process your claim with reasonable promptness.
Please note, we cannot and will not enter claims for damages. If we filed claim here, it would be sent to your local freight agent
for verification and investigation. This time can be saved by your filing the claim directly. Every consignee is on the ground
floor and in contact with the local agent who inspects the damaged goods, and thus, each claim can be given individual
attention.
Since our goods are packed to comply with the regulations of all railroad, truck, and express companies, we cannot allow
deduction from any invoice because of any damage, however, be sure to file your claim promptly. Our goods are sold F.O.B.
factory. We take receipt from the transportation company certifying that the goods were delivered to them in good order, and
our responsibility ceases.
It is seldom that any breakage or damage occurs in any of our shipments, and in no case will the customer be out any expense if
they follow the above instructions.
Be sure to keep all damaged goods subject to examination of the truck or express company inspector, who may call on you
some time later. These damaged goods, of course, will belong to them, and they will inform you what to do with them. If you
dispose of these damaged goods, your claim may not be paid.

2. General Description and Specifications
Super Vac ventilators are specifically designed to provide a convenient and portable source of fresh air. Refer to decal affixed to
ventilator to determine proper operating voltage requirements. Super Vac electric ventilators are single speed, fresh air
ventilators, for use in extreme conditions.
Specifications1
1Specifications are subject to change without notification. Refer to model decal affixed to ventilator to
determine actual specifications.
2EXP = Explosion proof motor, Class 1 group D, Class 2 Group E;F;G
This ventilator is designed for high powered air movement. Super Vac’s patented propeller produces a greater intake of air and
eliminates turbulence at the tips. The high velocity screw action sweeps air back over the motor, enabling it to run cooler. The
patented 7-Blade propeller is cast from aluminum alloy. Each blade is statically balanced for high efficiency and long life.
Explosion proof motors are U.L. rated, not the entire ventilator assembly.

3. Product Safety Precautions
ØDo not use the ventilator for purposes other than its’ intended use.
ØDo not disassemble or modify the ventilator in any way. Doing so may lead to mechanical failure or personal injury.
ØDo not wear loose clothing that could become entangled in the operating ventilator.
ØDo not operate ventilator without proper inlet or outlet guards in place. If guards are missing or damaged, contact factory
for replacements.
ØDo not place fingers or other foreign objects through inlet or outlet guards. Should a foreign object enter the ventilator,
immediately disconnect power source. Be certain all mechanical motion has stopped before removing foreign object.
ØDo not use with any power voltage other than the indicated voltage.
ØDo not place or operate ventilator on unsteady tables, slanted surfaces or other unstable surfaces.
ØNever handle energized power cords with wet hands.
ØNever let extension cords or plug connection lay in water. Locate the ventilator so that it cannot fall into water
inadvertently.
4. Before Operating Ventilator
§Always operate this ventilator from a proper AC power source supplied through a ground fault interrupter receptacle.
Test receptacle for ground fault before plugging in the ventilator power cord.
§A complete inspection of the ventilator should be made prior to operation.
§Never use power cords with frayed, cut, or brittle insulation.
§Inspect power cord plug for sound connections to the ground fault interrupter circuit.
§Check all threaded fasteners for proper tightness.
§Inspect inlet and outlet guards for damage or missing pieces. Replace damaged or missing guards before operating
ventilator.

5. Operation
Check ventilator inlet and outlet guards for obstructions. Check and remove from immediate surrounding area any objects that
could be drawn into the ventilator intake.
Place ventilator in desired location before connecting to power supply.
Extend and place any flexible duct as required. Use caution not to direct toxic fumes into confined spaces with the ventilator.
Please refer to the Super Vac Training Manual for Smoke Ventilation for comprehensive instruction on effective ventilation
practices.
Insert power cord plug into AC power receptacle. Pull out switch rod to begin ventilation.
To stop ventilation push in switch rod, remove power cord plug from AC power receptacle.
6. Maintenance and Repair
Maintenance should only be performed by experienced and trained personnel.
Be sure the ventilator is disconnected from the power source before performing any maintenance or repair.
The motor is of heavy duty ball bearing construction. The unit is completely sealed and requires no lubrication for the life of the
motor.
The ventilator blade should be specially checked for build-up of material or dirt which may cause an imbalance. Excessive
imbalance can lead to accelerated wear on motor bearings and vibration. Remove ventilator guards. Clean blade and inside
housing with mild detergent and water. Do not use abrasives, sharp instruments or caustic solvents that may scratch or damage
the aluminum alloy blade..
Intake and exhaust guards are not interchangeable. When replacing guards after cleaning, position them with the rings to the
outside with the row of spot welds holding the rings on the bottom.

7. Troubleshooting Motor Overheating Problems
CAUTION: Motors are equipped with thermal overload protection. When internal motor temperature exceeds design limits, the
motor will automatically shut off. Motor will automatically restart when it cools sufficiently after overheating. Remove power
cord plug from AC receptacle before examining or working on a motor which has stopped because of overheating. Thermal
overload protection sensitivity increases with frequency. Take preventative steps to correct cause of overheating to assure long
motor life. Most overheating problems are associated with the use of portable power generators as the ventilator power supply.
Common causes of motor overheating:
§Power generator not providing constant voltage. Ventilators are equipped with AC motors designed to operate
on power that falls between ±3% of design specifications.
§Using too small gauge of extension cord.
§Exceeding maximum length extension cord.
§Insufficient unobstructed distance on exhaust side of ventilator. Please refer to the Super Vac Training
Manual for Smoke Ventilation for recommended ventilator placement.
§Insufficient wattage generator. When running multiple ventilators on one generator, plug ventilators in one at
a time. Wait until first ventilator is running at full speed before connecting next ventilator to generator. Do not
exceed generator capacity.
§Using accessory ducting of too small a diameter or excessive length.
§Incorrect amperage circuit breaker for circuit load
§Using reeled or coiled extension cords.

8. Extension Cords
Do not use reeled or coiled cable. Reeled or coiled cable can produce a counter EMF (electromotive force). The counter EMF
can reduce the current carrying capability of an extension cord. This counter EMF will result in a voltage drop within the motor
instigating a thermal overload condition. Power supply must handle wattage requirements. When conditions require the use of
reeled cable, unreel all cable and place on the ground in very loose overlapping non-uniform coils.
