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.
