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.

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 scalding hot water. Opening the pump may
cause serious personal injury. In order to avoid the
possibility of personal injury, make sure the suction
and discharge valves are open and strainer pot
temperature iscool to touch, thenopen with extreme
caution.
Be sure not to scratch or mar the polished shaft seal
faces; seal will leak if faces are damaged. The
polished and lapped faces of the seal could be
damaged if not handled with care.
Motor Care
Protect from Heat.
1. It is recommended to shade the Clear generator
from the direct sun.
2. Provide ample cross ventilation to prevent
overheating.
Protect Against Dirt.
1. Protect from any foreign matter or splashing water.
2. Do not sure (or spill) chemicals on or near the

4. If a motor has been damaged by dirt it voids the
motor warranty.
5. Clean the lid and clamp, O-ring, and sealing
surface of the pump pot.
Protect Against Moisture
1. Protect from splashing or sprayed water.
2. Protect from extreme weather.
3. If a motor has become wet, let it dry before
operating. Do not allow the pump to operate if it has
been flooded.
4. If a motor has been damaged by water, the motor
warranty is voided.
Shaft Seal Replacement
The shaft seal consists primarily of two parts: a spring-
loaded member and rotating ceramic seal. The pump
requires little or no service other than reasonable care;
however, a shaft seal may occasionally become damaged
and must be replaced.
NOTE: The polished and lapped faces of the seal could be
damaged if not handled with care.

Pump Reassembly
1. When installing the replacement shaft seal, use
silicone sealant on the metal portion before
pressing into the seal plate, being careful to keep
off the seal face. Be sure the seal is full seated and
allow 24 hours for sealant to cure.
2. Before installing the rotating portion of the seal into
the impeller, be sure the impeller is clean. Use a
light density soap and water to lubricate the inside
of the seal. Press the seal into the impeller with
your thumbs and wipe off the ceramic and carbon
faces with a clean cloth.
3. Remount the seal plate to the motor.
4. Grease the motor shaft thread and screw impeller
onto the motor shaft.
5. Screw in the impeller lock screw (counterclockwise
to tighten.)
6. Remount the diffuser onto the seal plate. Be sure
the plastic pines and holding screw inserts are
aligned.
7. Grease the diffuser O-ring and seal plate gasket
prior to reassembly.
8. Assemble the motor subassembly to the pump
housing by using the two through bolts for proper
alignment. Do not tighten the through bolts until all
six bolts are in place and finger tightened.
9. Fill the pump with water.
10. Reinstall the pump lid and plastic clamp. Refer to
“Cleaning the Pump Strainer Basket” section of this
manual.
11. Prime the pump. Follow the Restart Instructions in
the next section for startup.
Restart Instructions
If pump is installed below the water level, close the return
and suction lines prior to opening the strainer pot on the
pump. Be sure to reopen valves prior to operating.
Priming the Pump
The pump strainer pot must be filled with water before
the pump is initially started. Follow the steps below to
prime the pump:
1. Remove the pump lid plastic clamp. Remove the
pump lid.
2. Fill the pump strainer pot with water.
3. Reassemble the pump lid and locking ring onto the
strainer pot. The pump is now ready to prime.
4. Open the air relief valve on the filter and stand clear
of the filter.
5. Turn on the pump.
6. When water comes out of the filter air relief valve,
close the valve. The system should now be free of
air and recirculating water throughout the system.
7. For variable speed and two speed pumps, pump
should run on high speed for priming.
The pump should not run longer than eight minutes
if priming is not achieved.
Do NOT run the pump dry. If the pump is run dry, the
mechanical seal will be damaged and the pump will
start leaking. If this occurs, the damaged seal must
be replaced. ALWAYS maintain proper water level.
If the water level falls below the suction port, the
pump will draw air through the suction part, losing
the prime and causing the pump to run dry, resulting
in a damaged seal. Continued operation in this
manner could cause a loss of pressure, resulting in
damage to the pump case, impeller and seal, and
may cause property damage and personal injury and
manufacturer warranties will be void.
Compressor Maintenance
Startup
Do not start against a vacuum or pressure load. Do not
remove relief valve head while unit is operating. If motor
fails to start or slows down significantly under load, shut off
and disconnect from power supply. Check that voltage is
correct for motor and that motor is turning in the proper
direction. If the motor runs in the wrong direction, it will
overheat.

Capacitors Replacement
Follow preventative maintenance schedule for capacitor(s)
replacement intervals. In standard units, there is one
capacitor for the main compressor. In Enriched Air units,
there is an additional capacitor for the enriched air
compressor. Before replacing a capacitor, make sure the
new capacitor has the same rating.
NOTE: Capacitors for the main and enriched air
compressors are not interchangeable.

Compressor Troubleshooting
Each unit is equipment with a main compressor that injects air into the nanobubble generator. Enriched air models have
an additional compressor called Enriched Air Compressor. Both compressors designs and operation principles are the
same. Troubleshooting guide below applies to both compressors.
Problem
Corrective Action
Motor Will Not Start
•Turn the system off.
•Check that plugs are fully inserted into the outlet inside the Clear.
•Check that the tube connection from the piping to the water pressure gauge. The compressors will
not start if there is inadequate water pressure or if the tube connection is loose.
•Check that voltage from power source matches that listed on nameplate.
•Check wiring connections against diagram on nameplate. Single voltage motors will operate only at
designated voltage.
•Reconnect electrical supply to unit. Check that power is on. If extension cord is used, check that it is
the correct size and length to adequately supply power to the unit.
•If unit will still not operate, contact your Gast Distribution / Representative or a Gast Authorized
Service Facility.
Motor Starts at 0 PSI
but Will Not Start
Under Pressure
•Replace the check valve.
•Wait for the thermal overload switch to reset before attempting to operate.
•If unit will not restart, the thermal overload switch may need to be replaced. If there is no thermal
overload switch, the motor may be damaged and requires service.
Motor Starts
Intermittently
•Disconnect electrical power supply from unit.
•Check that the tube connection from the piping to the water pressure gauge. The compressors will
not start if there is inadequate water pressure or if the tube connection is loose.
•Check points in the pressure or vacuum switch for wear or dirt.
•Check for dirt buildup or uneven wear.
•Replace parts as required.
A Leak is Located at
the Unit
•Vent all pressure from inside the air receiver until gauge reads 0 PSI.
•Inspect check valve for dirt buildup, wear, and proper operation.
•Replace check valve, if necessary.

Enriched Air System (Optional)
Operation
Units equipment with the Enriched Air system are capable
of increasing oxygen content of the air injected in to the
nanobubble generator up to 40% (double the ambient
content). The percentage varies by elevation and ambient
temperature.
Occasional adjustment of the enriched air pressure is
required to optimize the oxygen content of the enriched
air. Often, the adjustment is required when the ambient
temperature significantly changes. The adjustment is not
Nitrogen Membrane
The Enriched air system separate nitrogen from the air.
The membrane tank (Prism) accumulates nitrogen content
of the compressed air and exhausts it through the
enriched air back pressure regulator. The nitrogen filtered
or “enriched”air leaves the tank via a separate port, and is
used as the feed air to the main compressor. There is a
pressure gauge on the tank to monitor the enriched air
pressure. Pressure ranges are as followed.
Enriched Air Pressure Ranges
Optimal Range*
0 to 10 Psi
Maximum Range**
-5 to 20 Psi
*Adjust the pressure by turning the enriched air pressure
regulator knob.
**Exceeding this range may damage the enriched air
compressor or significantly reduce the enriched air oxygen
content.
NOTE: Moleaer’s remote monitoring system monitors the
enriched air pressure and sends alerts when the pressure is out
of the maximum range.
Maintenance
3-Stage Filter (For Enriched unit only)
3-stage filters must be cleaned every 6 months and
replaced annually. Refer to the preventative maintenance
schedule.
Follow steps below to remove the filters. Reverse the
steps to reinstall the filters.
