Congratulations! You’ve just purchased the Challengair 2000A.D. Animal Dryer, the Challengair

A warranty card is included with your product and should be filled out completely and mailed to Double K
Industries within 30 days of purchase to validate your warranty. Your Challengair 2000 or 2000Plus

has a two year limited warranty covering the unit against defects in materials and workmanship. See
warranty card for complete warranty information and exclusions.
Your Challengair 2000AD or 2000Plus has a brush type motor. It is important that the brushes be
changed when they become worn down to prevent damage to your dryer motor. We suggest checking the
motor brushes after every 600 hours of use. Please see section on “brush changing” in this manual for
instructions.
A note about dryer heat: Your Challengair 2000AD/2000Plus has no heating element. It produces heat
by a “flo-thru” motor system meaningthe air is pushed through the motorand is warmed by the natural
heat of the motor that occurs during operation. This means greater temperature after about 2-4 minutes of
operation. Obviously, the greater the room temperature, the warmer the air from the dryer.
Assembly
To attach hose for drying: Insert the gray hose adapter on the end of the hose firmly into the air outlet
snout. (Rotating while pushing is helpful. This is a tight fit but it will go in. Running the nozzle under hot
water for about 30 seconds will soften it and make it easier to insert into the snout.)
For Challengair 2000Plus or 2000EV Vacuum models only:
To attach hose for vacuuming: Insert gray hose adapter into the hole in the back of the unit.
Attachments: Your dryer/vacuum is equipped with one hose, 3 twist on nozzles, one slip-on super
velocity nozzle, and one cage attachment. Vacuum models also include on claw nozzle and one crevice
tool. Equine vacuum models also include a curry vacuum brush.
Removing and attaching nozzles: All threaded nozzles are reverse thread and are attached directly to the
hose. Turn clockwise to remove, counterclockwise to attach. To attach super velocity nozzle, first attach
high velocity nozzle to hose and then slip the Super Velocity Nozzle onto the high velocity nozzle.
For Equine models only: To attach the curry vacuum brush to the hose for vacuuming, attach the high
velocity nozzle to the hose end and then slip the curry vacuum brush onto the high velocity nozzle.

On vacuum units- remove the vacuum bag. d) Remove the motor filter disk from the motor by turning and
