Safety
Always use safe and common-sense precautions when working with Air-Care equipment. Do not block walkways with equipment, and remove delicate and breakable articles from the immediate work area. The following are precautions that should be reviewed by all persons who will be involved in the cleaning activity.
• There are no user serviceable components in the COBRA VII; only trained technicians should attempt to make internal repairs on this equipment. Call Air-Care 800-322-9919 for tech Support.
• Never use the COBRA VII in a wet environment.
• Always turn off the main power switch/Breaker on the COBRA VII panel when the brush and cable are laid down to prevent injury if the START switch is accidentally activated.
• Be sure all power cords and electrical extensions are rated to meet or exceed the original Air-Care power cord spec’s, and inspect AC power plugs to be sure the ground pin is in place.
• Never connect power to Air-Care equipment unless all covers and safety shields are in place. Mechanical and electrical parts could be activated and cause injury.
• Never allow anyone but a properly trained technician to use Air-Care equipment or cleaning products.
• All Air-Care equipment is designed for US standard 115 volt, 60 Hz AC. Most Air-Care equipment can be special ordered to meet other worldwide standards for a reasonable price and delivery schedule. Always check the specifications on the Equipment before connecting electrical power to Air-Care equipment.
• Keep the cable clear of breakable objects as it can flip and twist during higher torque applications.
• Turn off main power switch when removing or replacing the Flex-E-Bristle Brush. If you have questions about the safe use of any Air-Care product, call 702-454-5515.
Set-Up and Testing
1. Place the Cobra VII drive unit on the floor or other stable surface near the ducts to be cleaned.
2. Connect a power cord to the pigtail on of the rear of Power unit and to a standard 115 volt grounded AC outlet.
3. Attach the flexible shaft to the motor unit by first aligning the square end of the shaft with the square hole in the drive unit, then screwing the black disconnect nut onto the 2” diameter, threaded end of the coupler. This nut should be snug, but NOT excessively tight.
4. Hold the outer cable housing near the Flex-E-Bristle Brush. Hold the brush where it will not hit you or other objects when it begins to rotate. It should only be started AFTER it is inside an air duct.
5. Before turning on the circuit breaker on the left side of the panel, put both brush control switches in the OFF “CENTER” position AND set the brush speed to approximately “3” or “4” on the brush speed dial.
6. Using caution, select the “Panel” on the brush control switch.
7. The Brush can be started by using the BRUSH FORWARD or BRUSH REVERSE setting on the 2nd switch from the left. With the brush speed still set to 3 or 4, the brush should begin to turn slowly.
NOTE: If the brush does not turn, it may be necessary to uncoil the cable or increase the speed dial setting slightly.
8. Set the Switch back to the OFF or Center position to be sure the Brush Stops.
9. Press the “BRUSH REVERSE” setting on the bottom of the switch to verify that the brush rotates in the opposite direction.
10. Hold the brush cable approximately 12” from the brush end and keep it away from any breakable objects if you want to test the speed control white the brush is not inside an air duct.
a. Increase the “Brush Speed” Dial Setting to observe the brush speed increase
b. With Caution, press the “Brush Forward” button to change the direction of the brush.
11. Turn the Speed control dial back to “0” to verify the brush completely stops.
12. Return the Brush Forward switch to OFF, Center position.
13. To test the remote, Locate the White Remote control and use the Far Left Panel Switch to select “Remote”. Be sure that the Brush is either being held by the cable or laying in an area where it will not damage anything when it starts running.
14. Increase the Brush Speed dial to 3 or 4.
15. Press the Upper arrow on the remote and the brush should start to turn.
16. Press the Center button on the remote and the brush should stop.
17. Press the Bottom arrow on the remote and the Brush should begin to turn in the opposite direction.
18. It is possible to increase or decrease the speed of the brush with the Brush Speed dial.
19. While the brush is running, the direction of rotation can be changed by pressing the UP arrow on the remote.
20. Turn the Speed control Dial to “0” to stop the brush and press the Center button on the remote to turn off the brush motor.
21. The brush MUST BE STOPPED BEFORE INSERTING INTO AND OUT OF AN AIR DUCT.
22. Do not crimp the cable when storing or transporting. This may bend the strands in the cable causing premature fatigue and failure.
The Cobra VII brush is working properly. If you have any questions, contact Air-Care 702-454-5515,
Duct Cleaning with the Cobra VII and TurboJets
A. Bring the TurboJet into close proximity to the planned connection ducts.
B. Pre-vacuum and plug these openings.
C. Attach the Turbojet or other negative air machine to the system.
D. If the Return has a Filter, Remove the filter, place it in a Plastic bag and reinstall the filter into the return to block air flow through the air system during cleaning. Do not forget to remove this bag when the job is complete.
E. CAUTION: DO NOT INSERT OR REMOVE THE BRUSH FROM THE DUCT WHILE THE BRUSH IS TURNING
F. Begin at the duct opening farthest from the furnace/air conditioner.
G. With the Brush STOPPED, insert the brush and cable assembly one or two feet into the duct to be cleaned. THE MACHINE END OF THE CABLE MUST BE STRAIGHT FOR AT LEAST 4 to 5 FEET TO REDUCE THE FRICTION and HEATING OF THE CABLE HOUSING. A tight bend in the cable will cause friction that will damage the cable housing and cable resulting in costly repairs or replacement of the cable.
H. Start the brush by turning on the main power, press the START switch on the Remote and it will start in the lowest speed. The brush will begin to rotate within a few seconds. NOTE: The brush will begin to turn slowly in the Lowest Speed setting. Most duct cleaning will be done between 30 and 80 on the dial.
I. Push the Flex-E-Bristle Brush into the duct with a smooth gentle force. The brush will expand and compress to clean any size duct from 4” to 18” high and any width.
CAUTION: To clean duct board ducts, or older flex duct systems, the COBRA VII Brush system should be used at a lower speeds (30 or 40) with caution as its aggressive cleaning action may damage these delicate ducts. Internally insulated ducts, brittle flex ducts and fraying duct board ducts should NOT be cleaned with a power brush.
J. When the end of the duct is reached, the cable can be pulled slowly back toward the opening. If the duct is rectangular in shape, Press the “Change Rotation” on the Remote. The rotation of the brush in this direction will allow it to “Walk” to the opposite side of the duct from what was cleaned going into the duct and assure that both sides of the rectangular duct are cleaned.
K. Stop the brush 1 or 2 feet from the duct entrance then remove the brush. This duct opening can now be plugged with the foam plug, and the next duct opening cleaned in the same manner. Repeat this on each duct opening until all have been cleaned.
L. The duct system is now ready to be decontaminated by fogging in a duct deodorizer like Air-Care’s Envirocon.
Troubleshooting
Prior to troubleshooting, check the following.
1. Be sure power cord is plugged in, AND the Breaker/switch is in the “ON” with the Light Lit. If there is no light, try another outlet.
2. When testing the motor use the remote switch to turn the motor on for the first test.
3. For testing leave the Speed at the Low Setting of 30.
4. It is SAFER to run the COBRA VII with the cable end DISCONNECTED. You will be told when to attach it.
