grounding plug. Connect extension cord plug to a
matching 3-slot receptacle. Do not use an adapter. Make
sure your extension cord is in good condition. Check that
the wire gage of the extension cord is the correct size wire
to carry the current this product will draw. An undersized
cord is a potential fire hazard, and will cause a drop in line
voltage resulting in loss of power causing the product to
overheat. DIAGRAM B indicates the correct gage cord for
length required and the ampere rating listed on the product
nameplate.
If in doubt, use the next heavier gage cord. The smaller
the gage number, the heavier the wire gage.

Electrical Shock Hazard
WARNING
Guidelines for aquarium use
1. Close supervision is necessary when any air pump
is used by or near children.
2. To avoid injury, DO NOT disassemble the air pump.
3. Always unplug an air pump from an outlet when not
in use, before putting on or taking off parts and
before cleaning. NEVER yank a cord to remove the
plug from the receptacle. Grasp the plug and pull
to disconnect.
4. DO NOT use an aquarium air pump for other than
its intended use. The use of attachments which are
not recommended or sold by Gast Manufacturing
may cause an unsafe condition.
5. DO NOT install or store the air pump where it will be
exposed to the weather or to temperatures below
freezing.
6. Make sure an air pump mounted on a tank is
securely installed before operating it.
7. Read and observe all the important notices on the
air pump.
Injury Hazard
Product surfaces may become hot during operation,
allow product surfaces to cool before handling.
Do Not direct air stream at body. Air stream from
product may contain solid or liquid material that can
result in eye or skin damage, wear proper eye
protection.
Clean this product in a well ventilated area.
Failure to follow these instructions can result in
burns, eye injury or other serious injury.
WARNING
SAVE THESE INSTRUCTIONS.
WARNING – Read and follow all safety instructions.
To guard against injury, basic safety precautions
should be observed.
DANGER – To avoid possible electrical shock,
special care should be taken since water is
employed in the use of aquarium equipment. If the
air pump, cord or plug are damaged in any way
whatsoever, DO NOT attempt repairs by yourself,
return the air pump to a Gast Authorized Service
Facility for inspection and repair.
Precautions for aquarium use
1. If the air pump falls into the water, DO NOT reach
into the water to retrieve it.
2. Carefully examine the appliance after installation.
It should not be plugged into electrical power if there
is water found on any part of the pump.
3. DO NOT operate any air pump if it has a damaged
cord or plug, or if it is malfunctioning or has been
dropped or damaged in any manner.
4. To avoid the possibility of the air pump plug or
receptacle getting wet, position the 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,” shown above in the AQUARIUM
SETUP DIAGRAM, should be arranged by the user
for each cord connecting an aquarium air pump 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, which prevents water
travelling along the cord from coming into contact
with the receptacle.
5. If the plug or receptacle do get wet, DO NOT grasp
the plug to disconnect the air pump. Instead
disconnect the fuse or circuit breaker supplying
power to the receptacle. Then unplug the air pump
and examine for the presence of water on the plug
or receptacle.
