MC-01B EasyFill
™
Sensing Unit
User Manual
Thank you for purchasing the Level Waters ™ MC-01B
EasyFill
TM
Electronic Sensing Unit. It is the smallest
automatic, completely electronic water level sensing unit on
the market. The MC-01B is also available in a complete
system, the MLS-3401 that includes a power unit and
valve or the MLS-1002 with a 1” valve and power.
The MC-01B incorporates a dependable patented sensing
process in a economical design for those on a budget. 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 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.
Using our unique single plane geometric sensor design, the
MC-01B 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
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!
NEVER connect the sensor black lead to either power lead!
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 MC-01 Automatic Water Level Sensing Unit is simple to
install. A 24VAC Class 2 power unit with sufficient power
handling capability to power the supply valve (typically 350-
400ma) and a 24VAC irrigation valve will be needed for
installation. These may be purchased from many local
hardware stores. We recommend the following components:
• Stancor 4124 24VAC 300ma power supply
• Toro 53380 24VAC ¾” MPT irrigation valve
Installation will also require simple PVC pipe installation and
screw mounting 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:
• MC-01B EasyFill
TM
Sensing Unit
• Mounting Accessory Kit
Identify where the EasyFill
TM
will be mounted. The fill valve
should be mounted within reach of the control wires on the
EasyFill
TM
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
TM
Sensing
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 Unit
Determine a location where the EasyFill
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 EasyFill
TM
sensing unit so that the
probe window faces down toward the water
with the bottom edge of the window at the
lowest water level desired. To avoid
overflows, the bottom of the sensor probes
should fall approximately 1-½ - 2 inches below
the pond edge. The EasyFill
TM
has no capacity
for delaying fills in turbulent waters due to
ancillary water systems such as fountains and
waterfalls.
Therefore care must be taken
when choosing the mounting location and water level. If the
sensor height will need to be adjusted, MNT-EZ adjustable
mount 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 EasyFill
TM
housing. (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 EasyFill
TM
snuggly to the
mounting surface with the #8stainless screws provided. DO
NOT over-tighten the screws!
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
TM
sensing unit to the power supply and fill
valve requires that each connection be sealed from water
using self-adhering tape and electrical sealant.
