IMPORTANT SAFETY INSTRUCTIONS
WARNING - To guard against injury, basic safety precautions should be observed, including the following:
READ AND FOLLOW ALL SAFETY INSTRUCTIONS
To avoid possible electric shock, special care should be taken since water is employed in the use of aquarium equipment.
For each of the following situations, do not attempt repairs by yourself; return the appliance to an authorized service facility
for service or discard the appliance:
1. If the appliance falls into the water, DON’T
reach for it! First unplug it and then retrieve
it. If electrical components of the appliance
get wet, unplug the appliance immediately.
2. Carefully examine the appliance after instal-
lation. It should not be plugged in if there is
water on parts not intended to be wet.
3. Do not operate any appliance plug or recep-
tacle getting wet, position aquarium stand
and tank to one side of a wall-mounted re-
ceptacle to prevent water from dripping onto
the receptacle or plug. A “drip loop” should
be arranged by the user for each cord con-
necting an aquarium appliance to a receptacle. The “drip loop” is that part of the cord below the level of the receptacle,
or the connector if an extension cord is used, to prevent water traveling along the cord and coming in contact with the
receptacle. If the plug or receptacle does get wet, DON’T unplug the cord. Disconnect the fuse or circuit breaker that
supplies power to the appliance. Then, unplug and examine for presence of water in the receptacle.
c. Close supervision is necessary when any appliance is used by or near children.
d. To avoid injury, do not contact moving parts.
e. Always unplug an appliance from an outlet when not in use, before putting on or taking off parts, and before cleaning.
never yank cord to pull plug from outlet. Grasp the plug and pull to disconnect.
f. Do not use an appliance for other than intended use. The use of attachments not recommended or sold by the appliance
manufacturer may cause an unsafe condition.
g. Do not install or store the appliance where it will be exposed to the weather or to temperatures below freezing.
h. If an extension cord is necessary, a cord with a proper rating should be used. A cord rated for less ampreres or watts tan
the appliance rating may overheat. Care should be taken to arrange the cord so that it will not be tripped over or pulled.
SAVE THESE INSTRUCTIONS
GROUNDING INSTRUCTIONS
This appliance should be grounded to minimize the possibility of electric shock. This appliance is equipped with an electric
cord having an equipment grounding conductor and a grounding type plug. The plug must be plugged into an outlet that
is installed and grounded in accordance with all appropriate codes and ordinances.
The appliance is for use on a nominal 120-volt circuit, and has a grounding plug that looks like the plug illustrated in (A)
below. A temporary adapter which looks like the adapter illustrated in (B) and (C) below may be used to connect this plug
to a two-pole receptacle as shown in (B) if a grounded outlet is not available. The temporary adapter should be used only
until a grounded outlet can be installed by a qualified electrician. The green-colored rigid ear( lug, and the like) extending
from the adapter must be fastened to a permanent ground such as a grounded outlet box.
IMPORTANT: Airmax®, Inc. is not responsible for losses, injury or death resulting from a failure to follow these safety
precautions, misuse or abuse of equipment.

diffuser back to the pump. Air pumps may be used without protection although for longer life it is suggested that it be placed
indoors or under a protective ventilated cover. Keep pump as dry as possible. If left outdoors place it on a hard surface that
will stay dry during heavy rains.

the air filter cover. Extract the filter media from the pump and rinse thoroughly with cold water. Before replacing, wait for
the air filter to dry. Replace media into the empty filter cavity, replace the air filter cover and refasten. When the airflow
decreases, it is time to replace the diaphragms. There are two diaphragms, one at either end of the pump.
1. Disconnect the pump from the AC receptacle.

3. Unscrew the diaphragm assembly from either end of the pump.
4. Remove the diaphragm assembly.
