condition; replace if missing or damaged.
When installing and using this electrical equipment, basic
safety precautions should always be followed, including the
following:
Risk of Electrical Shock
Connect only to a branch circuit protected by a ground-fault
circuit interrupter (GFCI). Contact a qualified electrician if
you cannot verify that the circuit is protected by a GFCI.
This unit must be connected only to a supply circuit that is
protected by a ground-fault circuit interrupter (GFCI). Such
a GCFI should be provided by the installer and should be
tested on a routine basis. To test the GFCI, push the test
button. The GFCI should interrupt power. Push the reset
button. Power should be restored. If the GFCI fails to
operate in this manner, the GFCI is defective. If the GFCI
interrupts power to the pump without the test button being
pushed, a ground current is flowing, indicating the
possibility of an electric shock. Do not use this pump.
Disconnect the pump and have the problem corrected by a
qualified service representative before using.
General Warnings
Never open the inside of the pump drive motor enclosure.
There is a capacitor bank that holds a 230 VAC charge,
even when there is no power to the unit.
The Clear pump is capable of flowrates; use caution when
installing and programming to limit pump’s performance
potential with old or questionable equipment.
Code requirements for the electrical connection differ from
state to state. Install equipment in accordance with the
current National Electric Code and all applicable local
codes and ordinances.

Suction Entrapment Hazard
Stay off main drain and away from all suction outlets!
This generator produces high levels of suction and creates
a strong vacuum at the main drain at the bottom of the body
of water. This suction is so strong that it can trap adults or
children under water if they come in close proximity to a
drain or a loose or broken drain cover or grate.
RISK OF ELECTRICAL SHOCK OR
ELECTROCUTION
PUMPS REQUIRE HIGH VOLTAGE WHICH CAN
SHOCK, BURN, OR CAUSE DEATH.
BEFORE WORKING ON THE CLEAR PUMP,
always disconnect power to the pump at the circuit
breaker from the pump before servicing the pump.
Failure to do so could result in death or serious injury
to service person, system users, or others due to
electric shock.
NOTE: All suction plumbing must be installed in accordance
with the latest national and local codes, standards, and
guidelines.
A clearly labeled emergency shutoff switch for the
pump must be in an easily accessible, obvious
place. Make sure users know where it is and how to
use it in case of emergency. For installation of
Electrical Controls at Equipment Pad (ON / OFF
switches, timers, and automation load center.)
Install all electrical equipment, such as ON / OFF
switches, timers, and control systems, etc. to allow
the operation (startup, shutdown, or servicing) of any
pump or filter so the user does not place any portion
of his / her body over or near the pump strainer lid,
filter lid, or valve closures. This installation should
allow the user enough space to stand clear of the
filter and pump during system startup, shutdown or
servicing of the system filter.
This generator has been evaluated for use with
water only.
Before operation, be sure to completely rinse the
pump volute with water.
RISK OF ELECTRICAL SHOCK
This pump is supplied with a grounding conductor
and grounding type attachment plug. To reduce the
risk of electric shock, be certain that it is connected
only to a properly grounded, grounding type
receptacle.
Pumps improperly sized or installed or used in
applications other than for which the pump was
intended can result in severe personal injury or
death. These risks may include, but not limited to,
electric shock, fire, flooding, suction entrapment, or
severe injury or property damage caused by a
structural failure of the pump or other system
component.
The pump can produce high levels of suction within
the suction side of the plumbing system. These high
levels of suction can pose a risk if a person comes
within the proximity of the suction openings. A
person can be seriously injured by this high level of
vacuum or may become trapped and drown. It is
absolutely critical that the suction plumbing be
installed in accordance with the latest national and
local codes.
HAZARDOUS PRESSURE. STAND CLEAR OF
PUMP AND FILTER DURING STARTUP.
CIRCULATION SYSTEMS OPERATE UNDER
PRESSURE. WHEN ANY PART OF THE
CIRCULATING SYSTEM (I.E., LOCKING RING,
PUMP, FILTER, VALVES, ETC.) IS SERVICED,
AIR CAN ENTER THE SYSTEM AND BECOME
PRESSURIZED. PRESSURIZED AIR CAN CAUSE
THE PUMP HOUSING COVER, FILTER LID, AND
VALVES TO VIOLENTLY SEPARATE, WHICH
CAN RESULT IN SEVERE PERSONAL INJURY
OR DEATH. FILTER TANK LID AND STRAINER
COVER MUST BE PROPERLY SECURED TO
PREVENT VIOLENT SEPARATION. STAND
CLEAR OF ALL CIRCULATION SYSTEM
EQUIPMENT WHEN TURNING ON OR STARTING
UP PUMP. BEFORE SERVICING EQUIPMENT,
MAKE NOTE OF THE FILTER PRESSURE. BE
SURE THAT ALL CONTROLS ARE SET TO
ENSURE THE SYSTEM CANNOT
INADVERTENTLY START DURING SERVICE.
TURN OFF ALL POWER TO THE PUMP.

Remote Monitoring
Remote monitoring provides information about the unit’s
performance and the capability to send critical errors via
email or text messages to the registered users and the
factory. Furthermore, the performance parameters can be
monitored, and the data can be exported to a spreadsheet
for analysis.
Operation
Startup
1. On the suction side, ensure there is a screen or trap
at the intake to stop large debris from entering the
system. Intake screens should be made of PVC or
corrosion resistant metals. Contact Moleaer for the
intake install kit.
2. To avoid sediment buildup, the intake should be
elevated from the lake bottom. To avoid stalling the
pump, the intake should be at least 2 feet below the
water’s surface.
3. Discharge should be firmly fixed and pointed
directly towards the center of the water body to
avoid causing erosion. Avoid excessive twists or
bends when connecting piping to intake and
discharge.
4. Open intake and discharge valves, if any. Prime the
pump by removing the strainer lid, filling the
strainer basket with water, and replacing the
strainer lid before starting.
5. Open the lid and doors of the Clear enclosure to
access the controls. Ensure that power is
connected and turn the POWER disconnect switch
to the ON position. The light on the outside of the
enclosure will turn AMBER. Push and hold the
START button for 10 seconds, at which time the
light will turn GREEN you should hear the pump
start and begin self-priming.

6. It may take a few minutes for the pump to self-
prime. When the pump has successfully self-
primed, the strainer basket will be full, and the
pump will produce pressure. Normal operating
pressure range is 13 to 25 PSI (.896 BAR to
1.72 BAR). Max pressure limits are 8 to 30 PSI
(0.55 to 2.06 BAR). Do not exceed the maximum
pressure. Once the pump is producing adequate
pressure, the compressor(s) and cooling fan will
turn on.
7. To stop the unit, turn the red POWER disconnect
switch to the OFF position.
8. Close the doors and lock the lid during operation.
9. Gas flow is indicated on the left side of the unit on
the Rotameter. The center of the floating ball
indicates air flow rate. The gas flow rate is set at
the factory and is not field adjustable.
NOTE:
1. If the pond or lake does not have an existing aeration
system, the nanobubble generator should initially be
run periodically over the first seven days of treatment
to avoid an overabundance of bacteria causing a
decline in dissolved oxygen from de-stratifying of the
lake.
2. Expect to see algae float to the surface within the first
few weeks. This is normal. It may foul the intake screen
during this period; therefore, periodic inspections are
necessary until the algae float has subsided.
3. The unit will periodically open a dump valve to drain
liquid from the air filter.
4. Please contact Moleaer for the complete operating
manual for the compressor.

Maintenance
Intake screens should be cleaned periodically, along with
the pump basket. Inspect the intake multiple times per week
during the first month of operation and every three weeks
thereafter.
A drop in water pressure is most likely the result of a
clogged intake or check valve. If a drop in water
pressure is observed, inspect the intake and check
valve.
Once the initial treatment is completed, which is determined
by a reduction in or complete elimination in the presence of
algae floating on the surface, Moleaer recommends
monthly inspection (see monthly inspection list in the
manual) followed by quarterly cleanings of intake screens
and piping.
The gas injection zone (nanobubble generator) may require
periodic cleaning due to fouling buildup inside the piping. If
a reduction in air flow is observed on the rotameter, or the
gas pressure gauge increases by greater than 15% from its
starting pressure, or if the water pressure decreases by
20% from its initial pressure, a cleaning is necessary.
1. Please refer to Moleaer’s Clean-in-Place Service
bulletin for more information.
Pump Maintenance
Do NOT open the strainer pot if pump fails to prime,
or if pump has been operating without water in the
strainer pot.Pumps operated inthese circumstances
may experience a buildup of vapor pressure and
may contain scalding hot water.
Opening the pump may cause serious personal
injury. To avoid the possibility of personal injury,
make sure the suction and discharge valves are
open and strainer pot temperature is cool to touch,
then open with extremecaution. To prevent damage
to the pump and for proper operation of the system,
clean pump strainer and system every two weeks.
Pump Strainer Basket
The strainer basket (or “strainer pot”) is in front of the pump
housing. The strainer basket must be kept clean and free
of debris. Inspect basket through the lid on the top of the
housing.
Be sure to visually inspect the strainer basket four weeks.
More frequent inspection may be necessary in the first four
weeks of installation. Dirty strainer baskets reduce filter and
heater efficiency and put abnormal stress on the pump
motor. Bacterial fouling could cause the lid not to be clear.
Cleaning
1. Turn the red POWER disconnect switch to the OFF
position.
2. Relieve pressure in the system or allow it to reduce
by waiting for at least 15 minutes
3. Turn the lid and clamp counterclockwise and
remove from the pump.
4. Remove debris and rinse out the basket. Replace
the basket if it is cracked.
5. Put the basket back
into the housing. Be
sure to align the
notch in the bottom
of the basket with
the rib in the bottom
of the volute.
6. Fill the pump pot and
volute up to the inlet
port with water.
7. Clean the lid and
clamp, O-ring, and
sealing surface of
the pump pot.
NOTE: It is important
to keep the lid O-ring clean and well lubricated.
8. Reinstall the lid by placing the clamp and lid on the
pot. Be sure the lid O-ring is properly placed. Seat
the clamp and lid on the pump, then turn clockwise
until the locking ring handles are horizontal.
9. Turn the power ON.
10. Wait until a stead water flow is observable through
the pump basked lid.
THIS SYSTEM OPERATES UNDER PRESSURE
When any part of the circulating system (e.g., Lock
Ring, Pump, Filter, Valves, etc.) is serviced, air can
enter the system and become pressurized.
Pressurized air can cause the lid to separate, which
can result in serious injury, death, or property
damage. To avoid this potential hazard, follow above
instructions as described in page 4.
Always disconnect power to the Clear generator and
/ or pump at the circuit breaker before servicing the
pump. Failure to do so could result in death or
serious injury to service people, users, or others due
to electric shock. Read all servicing instructions
before working on the pump.
