1. Stand unit upright on blower base.
2. Release locking ring (C) with a coin or screwdriver, and rotate so
that lock symbol (A) is at top of ring.
3. Align locking ribs (E) on upper blower pipe with recesses (D) in
locking ring, and slide upper blower pipe into locking ring.
4. After inserting upper blower pipe into fan case so that line (F)
meets locking ring (C), rotate locking ring clockwise 1/8 turn to
lock upper blower pipe in place.
5. Align tabs (H) with grooves (G) and slide lower blower pipe over
upper pipe until there is light resistance. Do not force connection.
6. Hold upper pipe, and turn lower pipe clockwise, engaging posi-
tive locking channels until connection is firm. Do not force con-

positive locking system allows pipes to be tightened. If loosening
occurs, remove lower straight pipe, and install according to instruc-
tions 5 & 6.
