Manufactured with high-grade aluminum material to help absorb noise and keep your
LifeLine Air Pump whisper quiet.
Dual air chambers that produce strong air pressure.
Oil-lubricated design to provide pure compressed air
Unique structure and heat dissipating function.
Reliable, oil free, and extremely energy efficient.
LifeLine Aeration Kits are safe, energy efficient, and whisper quiet. LifeLine delivers high aeration
performance to create and maintain a healthy pond environment. LifeLine aeration enhances
pond oxygen levels by circulating the water. The air pumps can be used year round by regulating
oxygen levels in the summer, and keeping a hole in the icy water during the winter. LifeLine
areation kits are safe to use in both indoor and outdoor environments.
Please read this instruction manual carefully to provide optimal performance with your LifeLine
Aeration Kit.

flammable or explosive materials.
Disconnect the power supply to all devices used in water
before connecting your LifeLine Air Pump.
Disconnect the power supply to pump before performing any
maintenance procedures.
Do not operate pump with defective membrane/membranes.
Do not place air pump in water
Pump surfaces become very hot during operation, allow
surfaces to cool before handling.
Do not place air pump in water.
The safety of you and others is extremely important.
Failure to follow these instructions can result in electrical shock, burns, fire, or death.
ELECTRIC SHOCK
HAZARD
FIRE HAZARD
We have provided many important safety messages in this manual. Always read and
follow all safety messages.

Always keep aeration pump away from water.
Unplug or power off all devices before performing maintenance.
Pump may be used in freezing temperatures when in constant operation. Store pump in a dry
room temperature area if it will not be in constant operation.
The pump can be used for indoor and outdoor operation.
Use a clean damp cloth when washing the exterior of the pump. Make sure pump is unplugged.
Ensure that the power voltage and frequency to be utilized conform to the power requirements
specified on the product nameplate before use. Use a standard GFCI outlet.
This pump should be grounded while in use to prevent electric shock.
Pump surfaces become very hot during operation, allow surfaces to cool before handling.
If pump falls into water, unplug before retrieving it. Let qualified technicians check your pump
before using it again.
Carefully examine the appliance after installation, if the supply cord is damaged, it must be
replaced by a qualified technician in order to avoid hazard.
Do not carry pump by the power supply cord. Disconnect the plug when not in use and before
performing maintenance.
The unit is to be supplied through a residual current device (RCD) having a rated residual
operating current not exceeding 30mA.
Maintenance is required periodically to help ensure longevity of pump.
Immediately unplug the power cord during operation if any unusual activity occurs. Contact
your distributor or qualified technician.
Ensure that the power cord hangs below the electrical outlet to form a “Drip Loop”. This will
prevent water from running down the cord into the outlet.
Failure to follow the instructions and warnings in this manual may result in voiding of
warranty, pump’s damage, and/or serious injury. Be sure to read and save this manual for
future reference.

Place LifeLine Air Pump at least 7’ away from the pond in a dry location at room temperature.
Do not store air pump in an area that is highly humid. The metal components on the inside of
the pump can easily corrode. Damages resulting in incorrect installation will void the warranty.
Keep pump above water level to prevent returning water flow. Damages resulting in incorrect
installation will void the warranty.
Set up
Pg. 8 LifeLine Aeration Kit
Disconnect the power supply to all devices used in water before connecting your LifeLine
Air Pump.
Note: Never install or operate the pump in the vicinity of highly flammable or
explosive materials.
Interval operation: When the pump is powered off for several hours in intervals, condensation can
form from the inside of the unit. Store pump in a dry closed room at room temperature to help
prevent condensation from happening.
Place the diffuser discs in different locations under water for best aeration results throughout your
pond or water source. Weighted tubing will keep discs securely at the bottom of the water. Place
each discs no more than 10’ under water for best aeration results. See image above.
Failure to follow pump instructions will damage pump, or cause premature failure thus voiding the warranty.

Start-up
Switching on: Connect power plug to the socket. The unit switches on immediately when the
power connection is established.
Switching off: Disconnect the power plug.
Turn manifold valves on or off providing air to different diffuser discs and areas where you would
like air to reach.
Tubing Divider and Diffuser Discs Connection.
Diffuser discs are used to increase the oxygen levels in the water. The organic waste at the
bottom of the pond is broken down by bacteria, though the oxygen is also needed in the
process. Thanks to diffused air aeration , the oxygen transfer can take place. Dissolved
oxygen ends up in the water in every part of the pond creating a healthy water environment.
One or more discs can be connected to the pump after creating an air divider. Ensure all
tubing is tightly secured when installing your LifeLine Air Pump System.
Note: Avoid Sharp bends when laying out your weighted tubing with diffuser discs attached.
Discs will work effectively down to 10 feet.
Old or dirty diffuser discs will reduce aeration capacity. Make sure to follow maintenance
procedures periodically to prevent build-up from pump’s airway.
Ensure that the pump can discharge air at all times when powered on or it will heat up
leading to damage. Any damages due to not following instructions will void the warranty.
Never place pump in water. To guarantee a long service life, it is necessary to install the
pump under dry conditions free of moisture and dust. If pump becomes dirty, it can cause a
short service life. To extend the service life of your pump, it is critical to follow maintenance
procedures periodically.
Please note a temperature above 104°F can cause the diaphragm in your pump to fail.

Note: Never place air pump in water. To guarantee a long service life, it is necessary to
install the pump under dry conditions with no moisture or dust. Dirt, moisture, and/or improper
air flow and circulation around the pump can dramatically shorten pump life and cause
premature failure.
Pg. 10 LifeLine Aeration Kit
Storage
When the unit is in continuous operation it can remain in place at freezing temperatures.
Otherwise store unit indoors in a dry room (room temperature).
Manifold Valves
Manifold valves allow you to provide air to multiple diffuser discs in different locations around
the pond with a single air pump.
These valves come in a ³⁄₈” barb width. They allow you to turn the air on and off, plus they
allow you to control the air pressure to each diffuser disc. When diffusers are different
distances away from the air pump, you can adjust the valves so each diffuser has the same
amount of bubbling. See image below.
For 3-Way and 4-Way Manifolds, you will turn the red levers right or left to control
air pressure.

one diaphragm is defective. Failure to follow these instructions can result in electric shock,
serious injuries, or even death. Please contact a qualified technician if you did not wish to
undertake the replacement yourself.
Visit www.anjonmfg.com for a step by step guide on how to replace the diaphragm.

Maintain/clean air filter periodically: Remove protective cover, clean filter, and secure
cover back onto pump.
Replace diaphragm periodically. Diaphragms are not covered by warranty.
Clean or replace diffuser discs periodically. Diffuser discs are not covered by warranty.
Filter Sponge Cleaning and Replacement
Any dust or foreign matter attached on the pump air inlet may cause abnormal noises or result
in a failure of the pump.
1. Make sure to unplug the pump first before cleaning and maintenance.
2. Remove the filter sponge from the air inlet. Remove any dust or foreign matter from the air
inlet, the filter cover, and the filter sponge mounting surface.
If the sponge is heavily soiled, you can use a neutral detergent to wash the old sponge down.
Remember to rinse it well with water completely and dry it in the sun before reinstalling.
