and follow these instructions.
IMPORTANT SAFETY
INSTRUCTIONS
WARNING - To guard against injury, basic safety precautions should be
observed, including the following.
1.
READ AND FOLLOW ALL
SAFETY INSTRUCTIONS
and all important notices on the appliance before using. Failure
to do so may result in damage to the unit.
2. DANGER - To avoid possible electrical 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 yourself; return the appliance to the manufacturer for
service or discard the appliance.
A. DO NOT immerse in water. If the appliance falls into the water,
DO NOT reach for it!
First unplug it and then retrieve it. If
electrical components of the appliance get wet, unplug the
appliance immediately. (Non-immersible equipment only)
B. Carefully examine the appliance after installation. It should not
be plugged in if there is water on parts not intended to be wet.
C. Do not operate any appliance if it has a damaged cord or plug,
or if it is malfunctioning or if it is dropped or damaged in any
manner. The power cord of this appliance cannot be replaced:
if the cord is damaged, the appliance should be discarded.
Never cut the cord.
D. To avoid the possibility of the appliance
plug or receptacle getting wet, position
aquarium stand and tank to one side of a
wall mounted receptacle to prevent water
from dripping onto the receptacle or plug.
A
“drip-loop” (ill. A) should be arranged by
the user for each cord connecting an
aquarium appliance to a receptacle. A
“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 travelling 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.
It is recommended to always use a Check Valve in the airline
between the air pump and the aquarium.
3. WARNING: This appliance is not intended for use by persons
(including children) with reduced physical, sensory or mental
capabilities, or lack of experience and knowledge, unless they
have been given supervision or instruction concerning use of
the appliance by a person responsible for their safety. Children
should be supervised to ensure that they do not play with the
appliance.
4. To avoid injury, do not contact moving parts or hot parts such
as heaters, reflectors, lamp bulbs, and the like.
5. CAUTION: Always unplug or disconnect all appliances in the
aquarium 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.
6. 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.
7. For Indoor, household use only. Do not install or store the
appliance where it will be exposed to weather or to temperatures
below freezing.
8. This is an aquarium air-pump. Do not use this air pump for
other than its intended use (i.e.: do not use in swimming pools,
bathrooms, etc.).The use of attachments not recommended or
sold by the appliance manufacturer may cause an unsafe
condition.
Do not use this filter pump in swimming pools or other
situations where people are immersed.
Do not use this air pump with inflammable or drinkable
liquids.
9. Make sure an appliance mounted on a tank is securely installed
before operating it.
10. Read and observe all the important notices on the appliance.
11. If an extension cord is necessary, a cord with a proper rating
should be used. A cord rated for less amperes or watts than 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
INSTALLATION:
The air pump should be installed by following
either of the two recommended methods:
1.
Place the air pump on a surface lower than
the water level of the aquarium. To avoid
damage from accidentally spilled water, do not
place the air pump directly below the
aquarium.
Important:
It is highly recommended to
always use a Check Valve (sold separately) in
the airline between the air pump and the
aquarium.
(ill. B)
.
The Check Valve will help prevent water from
siphoning out of the aquarium through the air hose and into the
pump in the event of a power failure, or when removing filters and
other air-driven accessories from the aquarium.
2.
Place the air pump on a surface higher than the water level, such
as a shelf.The surface should be at least 12 inches (30 cm) higher
than the water level of the aquarium, but not be positioned directly
above the aquarium. The surface should have a raised edge to
prevent the air pump from sliding off. Use a Check Valve (sold
separately) in the airline between the air pump and the aquarium
to prevent back-siphoning.
(ill. C)
.
Once the air pump has been installed, do the following:
1.
Attach one end of the airline tubing (sold separately) to the air
outlet on air pump.
2.
Attach the other end of the airline tubing to a filter, an air stone, an
