System Maintenance

Q: Are there certain steps I should take to maintain my irrigation system?

A: Every Month: 1) Check your timer settings and make any adjustments, 2) Do the same with your sprinklers and sprays, 3) If you have a mainline filter, clean it out.

At the middle or end of the season: 1) Clean out the filters in all your sprinkler heads, 2) Operate each valve manually to check operation, 3) Look for damage on wires and wire nuts.

If trouble occurs: 1) First unclog sprinkler heads, 2) Make sure installation levels of heads are adjusted to ground level.

Sprinklers & Rotors

Q: How do I set my sprinkler?

A: To preset the arc adjustment:

1.) FIND THE LEFT START POSITION: First rotate the turret with your fingers around to the RIGHT (clockwise) until it stops. Then, rotate the turret around to the LEFT until it stops again. This is the LEFT START position. The sprinkler will begin spraying from this point and will rotate clockwise.

2.) To change the arc setting:

To INCREASE THE ARC, insert the K-Key into the arc indication ARROW SLOT at the center of the turret. While holding the turret with your fingers (so that it doesn't rotate), turn the Key CLOCKWISE, until the arc indication arrow points to the arc desired.

To DECREASE THE ARC, hold the turret, and turn the Key COUNTER-CLOCKWISE to the desired arc setting. ( IMPORTANT: DO NOT TURN THE ARC INDICATION ARROW PAST THE 360 SETTING OR PAST THE 30 SETTING )

3.) TO ADJUST THE ARC WITH THE SPRINKLER ON: If the sprinkler is turning to the right, hand-spin the turret to the right until it stops. Then, turn the turret to the left until it stops again. THIS IS THE LEFT START POSITION and you can now turn the arc indication arrow to the desired setting. ( See TO CHANGE THE ARC SETTING ) If the sprinkler is turning to the left, hand-spin the turret to the left until it stops. ( See TO CHANGE THE ARC SETTING ) IMPORTANT: DO NOT TURN THE ARROW PAST THE 30 SETTING OR PAST THE 360 SETTING.

Q: How do I change nozzles on my sprinkler?

A: All K-Rain sprinklers are preset for you with a 90 arc setting, and include a pre-installed #2.5 nozzle (except the K1 SmartSet, which comes with a pre-installed #1.5 nozzle.) To change the nozzle:

1.) USE YOUR KEY: After you remove the nozzle retention screw with your K-Key, insert the Key into the keyhole on top of the turret. Then, turn the k-key 1/4 turn so it doesn't slip out of the hole when you pull it up.

2.) PULL UP THE RISER: Firmly pull the entire spring-loaded riser with the key to access the nozzle socket. Hold the riser up with one hand.

3.) REMOVE THE NOZZLE: With the nozzle retention screw removed, insert the K-Key into the slot directly under the nozzle "prongs" at the top of the nozzle. Now, pivot your key 1/4 turn to "hook" the nozzle and pull the nozzle out.

4.) INSTALL A NEW NOZZLE: Press the desired nozzle into the nozzle socket. Make sure the nozzle number is visible and the nozzle "prongs" are up. Then re-install the nozzle retention screw. NOTE: The nozzle retention screw is also a break-up screw and adjusts the distance of the spray.

Q: How do I change nozzles on my Dial-A-Nozzle sprinkler?

A: To select a nozzle, with riser popped up, hold the serrated ring with one hand. Insert flat screwdriver or K-Key into nozzle selection keyhole on top of turret. Rotate screwdriver or K-Key until desired nozzle is aligned with breakup screw location. Breakup screw ( provided in box ) can be used to adjust the radius.

( NOTE: Nozzle Ring Can Not Be Rotated When Radius Adjustment Screw Is Installed )

Q: How do I clean out the filter?

A: INSPECTING THE FILTER: Unscrew the top and lift the complete sprinkler assembly out of the housing can. The filter is on the bottom of the sprinkler assembly and can be easily pulled out, cleaned and re-installed.

Q: What if my sprinkler isn't turning properly?

A: CAUTION: On new installations, be sure to verify that you have flushed your lines prior to installing sprinklers. Otherwise you will have loaded your sprinklers with sand. If your sprinkler isn't turning properly, try cleaning the filter ( see above ). If sand gets into the sprinklers gears, they will clog up and quit rotating. At this point they can no longer perform and the entire sprinkler must be replaced.

Q: What should I do before installing my sprinklers?

A: PROFESSIONAL TIP: Always blow out your lines first before installing new sprinklers.

Controllers and Timers
( Model #1000, 2000 & 2500 Series )

NOTE: Disconnect power prior to working on power or load.

Q: What do I do if my controller fails to keep proper time?

A1: There may be no power or improper voltage going to the motor. If so, check the Electrical Circuit and Connection Diagram or proper connection of power to controller. Check voltage supply to ensure voltage to motor is 120 or 240 volts as specified for model type.

A2: Your clock motor may be turning but the time dial is not turning. The drive gear located behind the time dial may be broken. If so, remove the time dial and inspect the drive gear. Install a new drive gear noting "this side out." Reinstall the time dial and be sure it turns freely clockwise.

Q: What do you recommend if my controller won't turn OFF?

A1: If your switch is being activated, ensure that wires do not push against the switch or relay. Check that wires leading to the switch are not pulled out.

A2: Your controller may be improperly wired. Check the Electrical Circuit and Connection Diagram and make sure that the input wires are not wired directly to load.

A3: A switch adjustment may be needed for proper automatic operation. Make the needed switch point adjustment as outlined in last question on AUTO MODE. (See below)

A4: The switch knob may not be in the OFF position. Be sure to turn the Auto-Off-On switch to OFF.

Q: What if my controller does not turn ON in the manual mode?

A: That means no power is getting to the controller. First be sure that the controller is properly wired as per the Electrical Circuit and Connection Diagram. Also check your circuit breaker.

Q: What if my controller fails to operate properly in automatic (AUTO) mode?

A1: This may be due to the Daywheel not being properly programmed. Check the Setting and Operation instructions for programming the Daywheel.

A2: Your Auto-Off-On knob may not be set properly
Be sure to turn the Auto-Off-On knob to AUTO position.

A3: The switch may need adjusting. Remove the controller face from its enclosure after disconnecting power to the unit. The switch adjustment screw is located on the switch cover. A clicking of the switch should be heard when the switch arm is slowly pulled back at the halfway point between the edge of the time dial and the far edge of the timing pin. With a small screwdriver, tighten the screw clockwise to cause the switch to active sooner. If the switch is activating sooner than desired, turn the adjustment screw counterclockwise slightly.

A4: The switch contacts or relay may be worn out.
Replace switch or relay (refer to parts list) ensuring that the controller is properly rewired. (Note: A nut driver tool is available to assist in removing black retainer nuts.)
