K-Rain MiniPro - User Manual

CHANGING A NOZZLE
1. REMOVING THE NOZZLE RETENTION SCREW
Use your K-Key (K) or a small flat blade screwdriver to remove
the nozzle retention screw (C) by turning counter-clockwise to
remove and clockwise to re-install.
2. PULL UP THE RISER
Insert the K-Key (K) in the keyhole (D) on the top of the nozzle
turret (M) and turn the key ¼ turn to insure that the key does
not slip out of the keyhole when you pull it up. Firmly pull up
the entire spring-loaded riser to access the nozzle socket (N).
Hold the riser assembly with one hand.
3. REMOVING THE NOZZLE
Insert the end of the K-Key (K), hook side up, into the tall slot
along the right side of the nozzle (J) and pull up to pop out the
nozzle. NOTE: Do not put the K-Key or any instrument into the
nozzle opening.
4. INSTALLING A NOZZLE
Press the desired nozzle into the nozzle socket (N). Make sure
the nozzle number is visible and the nozzle “wing” is up.
Then, re-install the nozzle retention screw (C).
NOTE: The nozzle retention screw is also a break-up screw
and used to adjust the distance of the spray.
SETTING THE ARC ADJUSTMENT
1. FINDING THE LEFT START POSITION
Place your finger on the top center of the nozzle turret (M).
Rotate the turret to the right until it stops and then back to
the left until it stops. Notice the position of the nozzle arrow.
This is the “Left Start” (L) position. The sprinkler will begin
spraying from this position and rotate clockwise until it
reaches the right “Arc Stop” (F).
2. ORIENTING THE LEFT START POSITION
Insert the K-Key (K) in the keyhole (D) on the top of the nozzle
turret (M) and turn the key ¼ turn to insure that the key does
not slip out of the keyhole when you pull it up. Being careful
not to allow the nozzle turret to turn, firmly pull up the entire
spring-loaded riser. Hold the lower riser assembly up with
one hand. Now turn only the lower riser (O) clockwise or
counter-clockwise until the nozzle arrow is pointing where
you want the sprinkler to begin spraying.
3. CHANGING THE ARC
Insert K-Key (K) or flat blade screwdriver into Arc Set Adjustment
slot (I). Turn clockwise to increase the arc or counter-clockwise
to decrease the arc. NOTE: The arc set arrow in the center of
the nozzle turret rotates to show the correct setting.
