Jandy Pro Series Levolor®II Electronic Water Leveler
Models K-2100 |Installation and Operation Manual

Section 2. System Description
Levolor II by Jandy Model K-2100 is a computer-
controlled ll 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 ll 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 ve (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.

3.2 Installing the Control Box
1. Mount the control box to the wall near the pump
and lter. See Figure 2. Do not install the control
box within 10 feet (3 meters) of the pool edges.
2. Mount the control box at eye level. Leave
sufcient clearance on all sides of the chassis
backplate.
3. Check the source voltage. (The unit is factory
wired for 220 volt operation.) To modify the
wiring for 110 volt operation, see Section 3.3,
Changing Wiring for 110 Volt Operation.
4. For 220 volt operation, connect the black wire to
line 1 and connect the black wire with the yellow
stripe to line 2. See Figure 3.

Refer to Figures 3 and 4 and do the following:
1. Cut the splice cap connecting the black/white and
the black/red wires. See Figure 3.
2. Connect the black/red wire with the black wire and
connect to the line side of power. See Figure 4.
3. Connect the black/white wire with the black/
yellow wire and connect to the neutral side of
power. See Figure 4.
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).

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
lter at the equipment pad or on a dedicated line back to
the fountain.
Zodiac recommends a minimum 1" valve and an anti-
siphon 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 grease-
lled 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 ow control knob (+) on the top of the
valve (See Figure 5) to set the ow rate to your
specications. (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.

Section 4. Operation
4.1 Controller Lights
The controller has ve (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 lling 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.

Section 5. Troubleshooting
Tools required: AC volt meter and No. 6 Phillips

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-
lled wire nuts or gel caps. Conventional wire
nuts lled 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.

5.2.2 Observe Operation
1. Restore power to the control box and observe the
operation. The control box is working if steps 2-7
in this section occur.
2. The Power light illuminates and turns green.
3. The Sensor light illuminates and turns yellow.
4. The Low Water Sensor light turns yellow.
5. Voltage is sent to the valve and relay.
a. After 20 seconds, the Fill light turns green
and you can measure 24VAC across the blue
wires with an AC volt meter.
b. After 20 seconds, the Low Water Cutoff light
turns green and you can measure 24VAC
across the red wires with an AC volt meter.
6. Make sure the sensor probes are touching the
water. Then connect the three (3) sensor wires
to the sensor. Refer to Table 1, Sensor Wire
Connections, page 11.
a. Connect the black wire for the Sensor
Common probe with the yellow wire in the
control box.
b. Connect the white wire for the Fill Sensor
probe with the yellow/blue wire from the
control box. The Fill light will turn off after
20 seconds.
c. Connect the red wire for the Low Water
Sensor probe to the yellow/red wire from the
control box. The Low Water Cutoff light will
turn off after 20 seconds.
7. Use an AC volt meter to conrm that there is 0
voltage at the blue wires in the control box and 0
voltage at the red wires in the control box.
5.2.3 Manual Valve Override
There is a manual ON/OFF lever on the valve body
located just below the solenoid. See Figure 6, Manual
Valve Lever, page 9.
If you are having a problem with the system and want to
override the electronic water Levolor, you can manually
open the valve by putting the lever in the up position ↑
(12 o’clock) for manual lling.
During normal operation, the lever must be in the
horizontal position → (3 o’clock) for controlled lling.
