1.5 Tools and Supply Requirement
1. Battery: 9-volt alkaline battery for the LEIT Key
2. Standard wire stripper
3. Flathead screwdriver (9/64” or smaller)
4. Concrete: approximately three 60 lb (27 kg) bags
5. Conventional waterproof wire connectors
2. INSTALLATION
Select the optimum location for the LEIT 4000 controller. If possible locate the controller in open area not adjacent
to a wall or building. We recommend installing a rain sensor with each controller with the use of adapter model
SKIT 8821-4.
2.1 Valve Installation Model 160HE-XXX (2-WAY)
Recommended version is a complete valve assembly including LEMA solenoid actuator with
plastic in-line valve (globe), sizes from 3/4” to 2”.
Maximum static operating pressure is up to 150 PSI.
1. Shut off the mainline to the valve.
2. Install series 160HE-xxx valves with a solenoid actuator according to a valve standard
installation specification (see Figure A on page 7).
3. After installation is completed, turn the water supply on and pressurize the mainline.
The valves will open momentarily and then shut off. Test each valve in manual operation by moving the holder/
handle from left to right to open and right to left to close the valve, making sure that the valve is operating
correctly. The valve should open momentarily and then shut off.
4. Splice the solenoid actuator hot wires (red) to one of the color-coded wires. Splice the solenoid actuator white
wire to the single incoming white (common) wire. Use 2 conventional dry-splice waterproof connectors. Leave
the wires slightly loose on each side so that repairs, if needed, can be carried out easily. Make sure not to
exceed the maximum run recommendation of wire distance (see page 7).
2.2 LEMA Solenoid Actuator Installation Model 1600HE (2-WAY)
Select the appropriate adapter for the valve(s) that will be used (see list on page 5).
The LEMA solenoid actuator operates only with 2-way normally closed valves.
Maximum static operating pressure is up to 150 PSI.
1. Shut off the mainline to the valve.
2. Unscrew the conventional solenoid from the valve and remove the solenoid housing,
solenoid stem, plunger, spring, and O-ring (if necessary).
3. Select the appropriate conversion adapters for the valve(s) then thread and tighten the
conversion adapter clockwise to the compatible valve port, do not over tighten.
4. Make sure that the solenoid holder/handle is not inserted into the solenoid housing,
and then, screw the LEMA 1600HE assembly into the correct adapter. Firmly tighten the
solenoid by hand, but do not over tighten.
5. Slip the LEMA 1600HE sleeve/handle into the solenoid housing. Positioning the solenoid
handle at a 40-45° angel towards the valve creates a manual lever; helpful for manual
on/off.
6. After installation is completed, turn the water supply on and pressurize the mainline.
The valves will open momentarily and then shut off. Test each valve in manual operation
by moving the holder/handle from left to right to open and right to left to close the valve,
making sure that the valve is operating correctly. The valve should open momentarily and
then shut off. If the valve remains open in manual operation, examine the adapter and the
sleeve to see that it is installed correctly and the adapter is firmly secured. Do not over
tighten the LEMA solenoid actuator to the valve and do not cross thread the adapter into
the solenoid cavity
4

NOTE: For all brand name valves with internal manual bleed lever, make sure the lever is in closed
position. Do not move the lever after installing the solenoid with the valve adapter. If the manual lever
on the valve is used, it can damage the adapter or the sleeve causing the valve to
stay open.
7. Splice the solenoid actuator hot wires (red) to one of the color-coded field wires. Splice
the solenoid actuator white wire to the incoming white (common) wire. Use 2 conventional
DRY-SPLICE WATERPROOF CONNECTORS. Leave the wires slightly loose on each
side so that repairs, if needed, can be carried out easily. Make sure not to exceed the
maximum run recommendation of the wire distance (see A1 below).
WARNING: The LEMA solenoid actuators must not be tested with any AC valve tester or DC tester
over 9-volts. If you do so, it will cause irreparable damage to the LEMA solenoid actuator and the
controller unit. Testing the solenoids with equipment rated higher than 9-volts will void the warranty.
2.3 Wire Installation and Distance
Run all direct burial wires along their respective trenches from each valve box to the controller location. Use
selection of color-coded direct burial wires to connect to each solenoid red (hot) wire. Use white (common) wire to
connect to the solenoid’s white (common) wire. Make sure to label each color-coded wire inside the irrigation box
with the designated station number.
MAXIMUM WIRE DISTANCE
Wire gauge recommendation LEMA 1500S SOLENOIDS LEMA 1600 HE SOLENOIDS
14 AWG (2.5 mm2) 1500 feet (300 m) 4,500 feet (1365 m)
12 AWG (4 mm2) 2400 feet (700 m) 7,500 feet (2272 m)
2.4 Controller Installation
1. To install the mounting column, set the curved bottom of the mounting column in a
12” x 12” x 12” (30 x 30 x 30 cm) frame and pour in the three 60 lb (27 kg) bags of
cement (see Figure A). Make sure the column is vertical and the opening in the curved
bottom is accessible and unclogged. All wires should route to the controller through
the bottom of the mounting column (see A1).
NOTE: Make sure the cement pad is dry before continuing with
the installation.

Part 1 Introduction
1.1LEIT X, XR and XRC controllers are advanced water-management irrigation controllers. The controllers utilize ambient light as the source of energy to
operate up to 28 valves using a low voltage, high efficiency, watertight, 2-way magnetic solenoid actuator that operates at 5-volts. Built to the highest
quality standards (ISO 9002), the LEIT X, XR and XRC controllers have a menu base program with straightforward programming that allows for a wide
range of irrigation programs such as valve grouping, 4 programs with 3 start times, run times up to 6 hours, budget, rain delay, status reports, history
reports, manual runs and more. The controller design uses the most advanced time-tested photovoltaic module, which provides more power to harness
light energy day and night, anytime, anyplace. Used for sprinkler or drip systems, the LEIT X, XR and XRC controllers are commercial quality water
management controllers for any type of environment and for a wide range of uses.

2.1Drawing File no.: LEITX.exe

2. Run the field wires along their respective trenches from the valve
box up to the bottom end of the mounting column. Make sure not
to exceed the maximum recommended wire distance (see chart
for maximum wire distance above). Push the wires up through the
column until at least 12” (30 cm) of wire extends from the top of
the mounting column (see B1).
3. Remove the door from the LEIT controller using the door key
(included) and slide the controller into place on top of the mounting
column. Make sure that 12” (30 cm) of wires are now inside the
controller and cannot slip back down into the column (see C1).
4. Insert the clamp spacer and the screw (included with the mounting
column) into the hole located on the lower left end of the controller.
Tighten the screw with the hex-key (included) until the controller
does not turn or twist and cannot be pulled off of the mounting
column (see D1).
5. Connect the station wires to the controller using a standard wire
stripper. Strip 3/10” of insulation from the tip of each of the station
colored (labeled) wires. Connect the color-coded (hot) wires into
the connector strip labeled with the station number and tighten
the connector screw using a screwdriver. Connect the white
(common) wire into either of the two common wire connectors
labeled “common” located at the lower part of the connector strip
and tighten the connector screw using a screwdriver. If using a
master valve, connect the hot wire from the master valve into the
station labeled “MV/P” (see Figure E1). For pump or other electrical
equipment, see detailed installations on page 10.
3. SENSOR INSTALLATION
The SKIT switch-type, weatherproof sensor adapter provides a quick, reliable way to connect a compatible rain,
freeze, moisture or other normally closed, switch-type sensor. The connection can be made either directly to the
LEIT series irrigation controllers or to one of the micro-powered solenoid actuators.
3.1 Sensor connection to unused station
If there is an unused station on the LEIT controller, connect the sensor directly using a SKIT 8821-4.
a. Run a red (hot) wire from the unused station connector position on the LEIT controller to the red (hot) wire
on the SKIT 8821-4. Then run a white (common) wire from the common connector station position on the
LEIT controller to the white (common) wire on the SKIT. Finally, splice the two SKIT black wires to the
sensor’s two normally closed (N/C) wires (see Figure B, Option 1).
3.2 Sensor connection if station is not available
If station is unavailable, or the controller is too far from the sensor, connect the SKIT 8821-4 to LEMA actuators at
a valve closest to the desired sensor location. This method can be used to minimize excessive wire runs (see Figure
B, Option 2).
b. Choose a valve that is closest to the sensor location. On the installed LEMA series actuator, splice the
red (hot) wire to the SKIT’s red (hot) wire AND to the red (hot) field wire creating a 3-wire connection.
Next, splice the LEMA’s white (common) wire to the SKIT’s white (common) wire and connect both onto
the common field wire. Again, a 3-wire connection should have been created. Finally, splice the two SKIT
black wires to the sensor’s two normally closed (N/C) wires.

3.3 Sensors compatible with LEIT controllers
Rain sensors are the HUNTER MINI-CLIK®and the RAIN BIRD RSD.
Moisture sensors are the IRROMETER, and WEM-B (battery).
Freeze sensor is the HUNTER FREEZE-CLIK®or RAINCLIK™ RFC (rain-freeze combo).
NOTE: Wireless sensors are not compatible with LEIT controllers.
4. PUMP OR ANY ELECTRICAL EQUIPMENT INSTALLATION
If it is required to switch ON a pump, fertilizer injector, fountain or light, two connection options are available using
the RKIT 8810S relay interface module.
The RKIT 8810S units are used to switch 10 amp electrical circuits to a voltage up to 250V AC or 30V DC.
NOTE: RKIT 8810S can be used with LEIT Series 4000, X and XRC.
4.1 RKIT Installation to the MV/Pump Terminal
To operate all the valves with the unit connected to (e.g. pump), connect the RKIT to the MV/Pump terminal
(see Figure C).
4.2 RKIT Installation to One of the Valve Station Terminal Connectors
Operate only the valve number that RKIT has been installed to (e.g. Fountain will turn on/off by only the station
that is using the RKIT).
To install the RKIT, run a red (hot) wire from the RKIT to any of the controller station terminals. Then, run
a white (common) wire from the RKIT to the common terminal connector or if not available, splice it to the
common field wire using a WATERPROOF CONNECTOR. Run the two black wires from the RKIT to the
AC/DC equipment and connect them to the corresponding circuit to be switched (e.g. pump start relay).
Make sure to use WATERPROOF DRY-SPLICE CONNECTORS for all connections.

Part 1 Introduction
1.1LEIT X, XR and XRC controllers are advanced water-management irrigation controllers. The controllers utilize ambient light as the source of energy to
operate up to 28 valves using a low voltage, high efficiency, watertight, 2-way magnetic solenoid actuator that operates at 5-volts. Built to the highest
quality standards (ISO 9002), the LEIT X, XR and XRC controllers have a menu base program with straightforward programming that allows for a wide
range of irrigation programs such as valve grouping, 4 programs with 3 start times, run times up to 6 hours, budget, rain delay, status reports, history
reports, manual runs and more. The controller design uses the most advanced time-tested photovoltaic module, which provides more power to harness
light energy day and night, anytime, anyplace. Used for sprinkler or drip systems, the LEIT X, XR and XRC controllers are commercial quality water
management controllers for any type of environment and for a wide range of uses.
