Section 2. System Description

Levolor II by Jandy Model K-2100 is a computer controlled fill device that detects low water conditions.

It can be used in any situation where a consistent liquid level is desired and the low water condition can be detected and acted upon. It is used to fill fountains and to circulate water in cooling towers, ponds, reservoirs, and storage tanks.

The K-2100 kit includes a sensor, remote sensor housing, control box and solenoid valve. For details about the materials in the kit and a list of additional materials needed to install the K-2100, refer to Section 3.1, Materials and Tools.

Sensor

The sensor has three (3) probes: one (1) short probe to measure the minimum operating level of the water, one (1) long probe to measure the low water cutoff level, and one (1) long common probe. The long probes come in 4″, 18″, and 30″ lengths.

The sensor housing is a slip type housing that glues to a 1″ coupling.

NOTE There is an optional threaded-type sensor for a threaded fitting.

Depending on the model, the sensor comes with 50 to 500 feet of wire at the top and three (3) stainless steel contacts at the bottom. The excess wire can be cut off after the installation has been completed.

Control Box

The control box has five (5) LED lights:

• Power On
• Sensor
• Fill
• Low Water Sensor
• Low Water Cutoff

For details about the functions of the LED lights, refer to Section 4.1, Controller Lights.

The control box is factory wired for 220 volt operation, but can optionally be rewired for 110 volt operation. See Section 3.3, Changing Wiring for 110 Volt Operation.

Valve

The K-2100 requires one (1) 24VAC solenoid valve. The Jandy-supplied valve (Part No. SOL100) has a pressure rating that cannot exceed 125 PSI.

2.1 Electrical Specifications

3.4 Grounding

Connect the green ground wire marked to the grounding terminal of your electrical service or supply panel with a continuous copper conductor having green insulation.

The copper conductor must be equivalent in size to the circuit conductors supplying this equipment, but no smaller than No. 12 AWG (3.3mm).

Refer to your local codes for the acceptable grounding wire gauge.

3.5 Installing the Valve and Relay

NOTE Install the valve with the directional water flow arrow pointing in the appropriate direction. The directional water flow arrow is located on the inlet side of the valve.

A 24VAC solenoid valve will provide water from a supply line to the fountain (or other environment: cooling tower, pond, reservoir, storage tank, etc.).

You can install the supply line either before or after the filter at the equipment pad or on a dedicated line back to the fountain.

Zodiac recommends a minimum 1″ valve and an antisiphon valve, which provides inexpensive insurance against accidental draining of the fountain (or other environment).

Always use an in-line strainer, which can be purchased from Zodiac.

1. Connect the 24VAC water solenoid valve to the 18-gauge solid-core burial cable using greasefilled wire nuts.
2. Connect the wires from the Fill Valve to the blue wires in the control box using wire nuts. See Figure 7, page 10.
3. Connect the wires from the Low Water Cutoff AC Relay Coil to the red wires in the control box using wire nuts. See Figure 7, page 10.
4. Turn the flow control knob (+) on the top of the valve (See Figure 5) to set the flow rate to your specifications. (The rate can be set up to 30 GPM.)
5. Put the manual ON/OFF lever, located just below the solenoid, in the OFF position, so it can only be opened by the electronic water Levolor. See Figure 6.

NOTE When mounting a slip-style sensor in a static pipe, glue 1″ fittings with 793 IPS brand ABS/PVC glue. Do not glue 2″ fittings.

Section 4. Operation

4.1 Controller Lights

The controller has five (5) lights. See Figure 10 and Table 2, LED Indicators.

The Power light turns green when the power is on. The Sensor light turns yellow when water is not touching the Fill Sensor probe.

Then the Fill light turns green, indicating that the valve is operational and filling the fountain (or circulating water in another application). The Fill light turns red when the unit enters Safety Lockout Mode.

The Low Water Sensor light turns yellow when the Low Water Sensor probe is not touching the water. Then the Low Water Cutoff light turns green, indicating that the pump is being shut off.

4.2 Fill Safety Lockout Mode

The Levolor is equipped with a Fill Safety Lockout Mode. This means that if the Fill Sensor probe has not been touched by water within the pre-set Fill time period, the Levolor activates the Safety Lockout, turning the valve off for 24 hours. During Safety Lockout, the Fill light turns from green to red.

The pre-set factory Fill time is 20 minutes. To change it, see Section 4.3, Change Fill Time for Safety Lockout Mode.

Figure 10. Controller Lights

Table 2. LED Indicators

4.3 Change Fill Time for Safety Lockout Mode

To change the pre-set factory Fill time, turn off the power to the control box, open it up, and cut one or both jumpers on the circuit board.

WARNING

Turn off the power to the control box before starting this procedure. Failure to comply may cause a shock hazard, resulting in severe personal injury or death.

1. Shut off the power to the control box.
2. Take the upper cover plate off the control box by removing the three (3) screws that secure it.
3. Locate the jumpers at the top left of the circuit board. See Figure 11.
4. Modify the Fill time by cutting Jumpers A and/or B, as shown in Table 3, below.

Table 3. Fill Safety Lockout Mode Settings

NOTE Cutting the S-1 Jumper will disable the SafetyLockout function.

5. Replace the top cover plate, being careful to align the LED lights with the plastic lenses in the cover.
6. Install the three (3) screws. Do not tighten or you will damage the plastic mounts.
7. Restore the power to the control box. The new timing changes will take effect.

NOTE If you change the Fill Safety Lockout Mode settings without turning the power off in advance and on afterwards, you will need to cycle the power from OFF to ON for the new timing changes to take effect.

Figure 11. Safety Lockout Jumpers

Section 5. Troubleshooting

Tools required: AC volt meter and No. 6 Phillips screwdriver.

5.1 Observations at Job Site

Make these initial observations when at the jobsite.

1. Proper wire usage between the controller and the valve. (Burial style polypropelene-jacketed solid-core wire (at least 18-gauge wire): the same wire as the sensor wire.)
2. Proper wire nuts at the valve connection. (Grease-filled wire nuts or gel caps. Conventional wire nuts filled with silicone will not work since some silicones have acids that degrade copper wires.)
3. Sensor wire is continuous and not spliced. (No splices between the tips and the controller.)
4. Proper use of sensor: slip style for static pipes.
5. Proper power input voltage to the box and proper wiring for the voltage (110 or 220 VAC).
6. Remove top face plate to verify that control lights on PCB line up with the lens cover.

NOTE Before making changes to connections or settings, reset the controller by powering off for 10 seconds and then powering back on.
