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 air. Super Vac positive pressure
ventilators are tested to AMCA PPV Standard 240-95, for use in extreme conditions.

Specifications are subject to change without notification. Refer to model decal affixed to ventilator to determine
actual specifications.
This ventilator is designed for high powered air movement. Super Vac’s propeller produces a greater intake of air and eliminates
turbulence at the tips. Each blade is statically balanced for high efficiency and long life.
This document is designed to function as a quick start guide and not an in-depth comprehensive instructional manual. Please read
all accompanying documents shipped with your ventilator. Due to the many features of powered equipment thorough familiarity
with the operating controls is essential to assure safe and trouble free operation.
3. Product Safety Precautions
¾Do not use the ventilator for purposes other than its’ intended use.
¾Wear eye and ear protection when operating the ventilator.
¾Never operate ventilator while fatigued.
¾Do not disassemble or modify the ventilator in any way. Doing so may lead to mechanical failure or personal injury.
¾Do not wear loose clothing that could become entangled in the operating ventilator.
¾Never permit anyone to operate ventilator without proper instruction.
¾Do not operate ventilator without proper inlet or outlet guards in place. If guards are missing or damaged, contact factory
for replacements.
¾Do not place fingers or other foreign objects through inlet or outlet guards. Should a foreign object enter the ventilator,
immediately stop engine. Be certain all mechanical motion has stopped.
¾Do not place or operate ventilator on unsteady tables, slanted surfaces or other unstable surfaces.

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 starting.
The two graphs allow you to establish with
precision the best utilization of the apparatus.
Graph 1 depicts rotational speed and water
consumption depending on input feed pressure.
Graph 2 depicts the usable horsepower depending on
the driving torque.
Example: If the inlet pressure of the water supplied
to the motor is 174 psi, and the resisting torque
of the driven machine is 7.4 lb/ft, the rotational
speed is 4560 rpm, water consumption is 117 gpm
(graph 1) and the usable power is 5.5 HP (graph 2)

6. Inlet and Discharge Position
As delivered, the standard position of the inlet and discharge connections on your 720WT allow for easier connection of water supply lines. This
positioning does not allow full range of tilt positions.
If your application requires the use of the two back tilt positions the inlet and discharge blocks on the water turbine motor may be rotated 90 degrees.
Using a 3mm hex key (not supplied) remove the 4 screws on the block , turning the block to the desired location , reinstalling the 4 screws. Use care to
assure the o-ring is in place for proper seal. Torque screws to 3 lbs./in ( .33 N-m), check for leaks, re-torque as required.
