User Manual
Thank you for purchasing the Level Waters ™ LSX-450
EasyFill X
TM
Electronic autofill system. It is the smallest
automatic, completely electronic water level sensing unit on
the market.
The MCX-11 control sensing unit incorporates a dependable
patent pending sensing process and includes features found
only on large professional systems, like the wave
compensation delay and third failsafe probe. It may be used
in many applications including ponds, water gardens,
fountains and other water features. It is also suited for large
industrial applications like cooling towers water make up.
The Unit uses no external moving parts and will not clog like
standard float valves can. It is hand assembled from PVC
material instead of molded ABS plastic. PVC provides for
better endurance in sunlight and heat and will extend the life
of the components over time than using other plastics would.
The MCX-11 control sensor 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
Pond Water Level Sensing 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 LSX-450 Automatic Water Leveling System is simple to
install. A 24VAC irrigation valve with a maximum 450ma
inrush current rating will be needed for installation. Various
size valves may be purchased from many local hardware
stores.
Installation will also require simple PVC pipe installation and
screw mounting the snap-in mount or the sensing 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-11 EasyFill X
TM
Control Sensing Unit
• PS-24A 450ma power supply
• MNT-EZX Snap-In Mount
• Mounting Accessory Kit
• Probe cleaning wire brush
Remove the control sensor from the MNT-EZX by carefully
pushing the capture post over the edge of the sensor and
angling the sensor out.
Identify where the EasyFill X
TM
will be mounted. The fill valve
should be mounted within 50 feet of the control wires on the
EasyFill X
TM
and connected using irrigation zone wire. 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 six feet of the EasyFill X
TM
Sensing Unit to install the power module. Do not extend the
power wires or the unit may not sense properly and doing so
will void the warranty.
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 Unit
Determine a location where the EasyFill X
TM
sensing 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 MNT-EZX Snap
Mount so the bottom edge of the
mount is at the lowest desired
water level. To avoid overflows,
the middle short probe should be
below the pond edge. If the sensor
height will need to be adjusted, MNT-EZX adjustable mount
(sold separately) will need to be installed. This will not be
needed for most installations.
Mark the mounting surface to match the two mounting holes
in the MNT-EZX Snap Mount. (If no holes are desired, the
unit may be affixed using silicone sealant) Drill a small #4
pilot hole at the marks and screw the snap mount snuggly to
the mounting surface with the #6 flathead stainless screws
provided. DO NOT over-tighten the screws!
Install the MCX-11SW sensor control by angling it so that
one of the mounting holes is above the corresponding stand-
off posts and firmly but gently push the sensor housing into
the clamp so that both latches catch the top edge of the
sensor control.
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.
