MCX-11SW EasyFill X
™
Sensing
Control Unit User Manual
Thank you for purchasing the Level Waters ™ MCX-11SW
EasyFill X
TM
Electronic Sensing Control Unit. It is the smallest
automatic, completely electronic water level sensing unit on
the market. The MCX-11SW is supplied with our complete
systems, the MLX-3420 that includes a power unit and 3/4"
valve or the MLX-1020 with a 1” valve and power.
The MCX-11SW incorporates a dependable patented
sensing process in a economical design and provides
professional filling functions without large controllers. It may
be used in many applications including ponds, water
gardens, fountains and other water features.
The Unit uses no external moving parts and will not clog like
standard float valves can. It is the only professional grade
auto-fill that combines the control circuitry within the sensor
housing. It includes an approximate 7 second wave
compensation delay and a failsafe probe to ensure against
overfill.
The MCX-11SW provides dependable filling in a simple
design to achieve an optimum water level. Installation is a
snap with simple plumbing and wiring.

Safety Overview
The EasyFill X
TM
Water Level Sensing Control Unit is
designed to provide the user a safe product that is easy to
install and use. When installed as described in this manual,
the system presents no unsafe shock hazards. However,
altering any of the components may present an unsafe
circumstance.
Some other considerations to keep in mind during
installation and operations are as follows:
Always use a Class 2 power limiting supply.
Never mount a power supply made for indoor use in an
outdoors environment where it will get wet. Follow all
manufacturer instructions when installing a power
supply.
Do not insert metal objects into sensor probes while unit is
turned on.
Do not break seals on unit. Doing so may expose the user
to potentially dangerous voltages when unit is turned on and
will void the warranty.
Do not plug the power supply in until all wiring is complete
and leads are not exposed!
Always use safety equipment, such as eye protection, and
dust mask when cutting PVC piping along with other normal
safety precautions.
Always carefully follow all installation instructions.
Installation
The MCX-11SW Automatic Water Level Sensing Control
Unit is simple to install. A 24VAC Class 2 unbalanced power
unit with sufficient power handling capability to power the
supply valve (typically 350-500ma) and a 24VAC irrigation
valve will be needed for installation. These may be
purchased from many local hardware stores. Note: It is
important not to use a power source that is referenced to
ground on one phase (balanced) and that the water is not at
ground potential. This will cause the unit to not operate
properly.
Installation will also require simple PVC pipe installation and
mounting the sensing control unit along with simple wiring.
The limited plumbing that is necessary to provide the system
with filling water, requires only a hacksaw (or other
appropriate saw), PVC cement and sufficient PVC and
adapters.
Preparing for Installation
Open the package and ensure that all of the components are
present and have not been damaged in shipping. Items
included in the system are:
• MCX-11SW EasyFill X
TM
Sensing Control Unit
• MNT-XS
• Mounting Accessory Kit
• Wire brush for probe cleaning
Identify where the EasyFill X
TM
will be mounted. The fill valve
should be mounted within reach of the control wires on the
MCX-11SW. An outside water feed, such as a spigot will
need to be run to the valve and then to the water feature that
will be filled.
A weather-protected receptacle for power will need to be
located within a maximum of ten feet of the EasyFill X
TM
Sensing Control Unit to install the power module. Do not
extend the wires on the power unit or the power leads of
the sensor.
Warning! Always consult with an electrician when installing
electrical wiring! Not doing so could result in a dangerous
condition and/or noncompliance with electrical codes.
Installing the Sensing Control Unit
Determine a location where the EasyFill X
TM
sensing control
unit will be mounted (try to find an inconspicuous place.). If
the unit is to be mounted in a
skimmer, locate the surface it will
mount on and verify that the
sensor window will maintain the
level at the optimum height for the
skimmer.
Position the EasyFill X
TM
Sensor
with the probes 1/8" below the
desired water level. Use the supplied #8 screws to mount it
securely in place. To make cleaning the probes easy, install
a MNT-XS Snap Mount (sold separately) so the control
sensor can be easily removed and remounted. If the sensor
height will need to be adjusted, MNT-EZ adjustable mount
(sold separately) may be installed. This will not be needed
for most installations.
The short fail-safe probe between the sensing probes should
be positioned well below the top edge of the water feature so
that overflows do not happen
Installing the Valve
Plumb the input and output of the valve (follow
manufacturer’s instructions for valve) to an always-on water
source using PVC pipe or garden hose (see ‘Plumbing the
Unit’ for PVC installation tips). We recommend installing a
ball valve on the output of the valve to control flow volume to
the water feature.
Warning! The fill valve must be installed in an upright
position with the wires extending upwards from the unit
to function correctly.
Wiring the System
Wiring the EasyFill X
TM
sensing control unit to the power
supply and fill valve requires that each connection be sealed
from water using self-adhering tape and electrical sealant.

Warning! Do not plug the power supply in until all wiring
is complete and leads are not exposed! Doing so will
could cause damage to the power unit and void the
warranty!
Remove precut insulation from sensor and power supply
wire ends. Connect wires as shown in Diagram 2 using wire
nuts provided. Bend wire nut connection flat to length of wire
and wrap with self-adhering tape making sure to create a
proper watertight seal. Apply a liquid electrical sealant
(available at most hardware stores) to each connection. We
recommend that the unit be tested before weatherproofing
the connectors.
Note: It does not matter which red wire from the valve or
black wire from the power unit are used when wiring.
Connection Power Lead Sensor Lead Valve Lead

Plumbing the Unit
Using ¾” PVC pipe (available at most hardware stores) run
water supply from the fill valve outlet to the pond routing it
the way desired.
Parts needed:
• Hacksaw (or other suitable fine-toothed saw)
• PVC glue
• Required lengths of 3/4” PVC
• Required angle adapters.
Cut and fit all PVC pipe from the fill valve to the water
feature without gluing to make sure that the pipes are where
the user desires them.
Clean and glue all parts with general PVC cement to form a
watertight seal. Allow joints to dry for 24 hours before
connecting water to the system.
Plug the power supply into the weather-protected receptacle.
The unit is ready for operation
Operation
Once the EasyFill X
TM
is connected properly and plugged in it
will fill anytime the water level drops below the sensor probe
window after an approximate 7 - 10 second delay.
Note! If the level of the water at the time of power up is low,
the unit will fill until the water level reaches the probes before
turning off. Maintenance
The EasyFill X
TM
requires very little maintenance. Periodically
clean the sensor probes thoroughly with the supplied wire
brush or equivalent to remove debris and film. No other
maintenance is required.
Troubleshooting
The MCX-11SW EasyFill X
TM
Automatic Pond Leveling
Sensor should maintain the level in your pond for many
worry-free years. However, if you should experience
problems with it, it may be caused by some of these
common issues that can be resolved by the user:
 Pond overflows when filling
 Verify valve is installed upright, flow
direction is correct and manual fill screw
is tight.
 Verify proper connections with the
sensor control.
 Water may be at ground or voltage
potential. Measure with meter and
remove grounding source or check
submerged equipment for shorts.
 Pond will not fill
 Check to make sure power is available
at receptacle.
 Check for debris on sensor probes and
clean per instructions.
 Check to ensure connections are not
damaged and are covered with
weatherproof tape or sealant. Allow
connections to dry if necessary and seal
per the instructions.
