Check with a qualified electrician or serviceman if the
grounding instructions are not completely understood, or
if you are not sure whether the product is properly
grounded.  Do not modify the plug provided.  If it will not
fit the outlet, have the proper outlet installed by a qualified
electrician.

In the event of an electrical short circuit, grounding
reduces the risk of electric shock by providing an
escape wire for the electric current.  This product may
be equipped with a power supply cord having a
grounding wire with an appropriate grounding plug.
The plug must be plugged into an outlet that is properly
installed and grounded in accordance with all local
codes and ordinances.

Model that is permanently wired:

This product must be connected to a grounded,
metallic, permanent wiring system, or an equipment
grounding terminal or lead on the product.

Extension cords:

Use only a 3-wire extension cord that has a 3-blade
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.

Power supply wiring must conform to all required safety
codes and be installed by a qualified person.  Check
that supply voltage agrees with that listed on product
nameplate.

WARNING – Read and follow all safety instructions. To
guard against injury, basic safety precautions should be
observed.  

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.

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.

AQUARIUM SETUP DIAGRAM

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.
