4. Safety Instructions
WARNING: Read and understand all labels and operating instructions
before attempting installation.
o RISK OF ELECTRICAL SHOCK- This fan is supplied with a grounding conductor.
Improper connection of the equipment-grounding conductor can result in a risk of
electric shock. To reduce risk of electrical shock, connect only to a properly grounded,
grounding type receptacle.
o In the event of a malfunction or breakdown, grounding will reduce the risk of electric
shock by providing a path of least resistance for the electric current. Install electrical
hookup in accordance with all local codes and ordinances. Warning: Check with a
qualified electrician if you are in doubt whether the fan is properly grounded.
o To reduce risk of electric shock, disconnect power before servicing this fan.
o SAFETY CABLE- When suspending the fan using the C-Clamps, be sure to attach
the safety cable around the pipe grid and go through the handle of the Hurricane and
attach the cable to itself. It is mandatory to use a safety cable when suspending this
unit!
o C-Clamp- Be sure the Baby Spud has a solid unscrewable connection to the Spud.
When tightening the baby spud in place, always use the washer and cotter key.
Tighten the side lock bolt on the knurled area of the baby spud. Never loosen this lock
bolt to swivel the fan. Always swivel with the loosening of the swivel bolt on the side of
the C-Clamp and spin the entire spud/baby spud together. Tighten the swivel bolt
when in place.
5.Operating the Hurricane II FanTM
5.1 Unpacking the Hurricane II FanTM
Before removing from the box, note the position of the packing material and how the unit
is setting with the sprocket side down for future transport or boxing.
Pull the fan sprocket cover (foam block) and remove the clamping ring with an Allen
wrench. Slide collar over spindle toward fan until seated against the shoulder.
Once the bracket is completely slipped on, reapply the clamping ring until the shaft is
flush to the outside. Tighten securely with an Allen wrench.
5.2 Electrical Power Requirements
Check to see that the power switch on the handle is in the off position. Plug in the cord to
a grounded outlet with sufficient amperage. You may double check the voltage marking,
inside the mouth of the air output. The voltage requirement for this fan is acceptable to
almost all types of single-phase electrical supply. Current consumption is 10 amps at
110vac and 5 amps for the 230 VAC model. Make sure you are using an adequate
extension cord. These fans need at least 12-gauge extension cord for sufficient
amperage supply. Because initial current surge is higher, the fan should have a
