G INTRODUCTION
This instruction sheet will provide you with information required
to safely own and operate the Little Giant MDQ and MDQX series
aquarium pumps. The pump you have purchased is a magnetic
driven pump intended for aquarium use, to provide water movement
through filtration systems. The pumps are installed external to the
aquarium and filtration systems, and are generally mounted below
the aquarium in the cabinet that houses the filtration systems. The
pump head parts are made of glass filled polypropylene. The spindle
shaft and thrust washers are ceramic. The impeller driven magnet
is coated ceramagnet A (barium ferrite) type ceramic. O-ring seals
are nitrile. The motor is thermally protected.
This instruction sheet covers the standard models in this pump
series. This form is applicable to other models in this series not
listed by catalog number in the replacement parts list section of
this pamphlet. If the catalog number of your pump is not listed in
the replacement parts section, then caution should be exercised
when ordering replacement parts. Always give the catalog num-
ber of your pump when ordering replacement parts.
The Little Giant unit you have purchased is of the highest quality
workmanship and material. It has been engineered to give you
long and trouble-free service.
The Little Giant pumps are carefully packaged, inspected and
tested to insure safe operation and delivery. When you receive
your pump, examine it carefully to determine that there are no
broken or damaged parts that may have occurred during shipment.
If damage has occurred, make notation and notify the firm that you
purchased the pump from. They will assist you in replacement or
repair, if required.

SAFETY GUIDELINES
DANGER: To avoid possible electric shock, special care
should be taken in the use of aquarium equipment. For each
of the following situations, do not attempt repairs yourself;
return the appliance to an authorized service facility for service
or discard the appliance.
1. Do not handle the pump with wet hands or when standing on
a wet or damp surface or in water.
2. 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. (nonim-
mersible equipment only)
3. Carefully examine the appliance after installation. It should
not be plugged in if there is water on parts not intended to be
wet.
4. Do not operate the pump if it has a damaged cord or plug, or if
it is malfunctioning or if it is dropped or damaged in any manner.
5. To avoid the possibility of the pump 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" should be arranged by the
user for each cord connecting an aquarium pump to a recep-
tacle (see Figure 1). The "drip loop" is that part of the cord
below the level of the receptacle or the connector if an exten-
sion cord is used, to prevent water traveling along the cord
and coming in contact with the receptacle. If the plug or recep-
tacle does get wet, DO NOT unplug the cord. Disconnect the
fuse or circuit breaker that supplies power to the pump. Then
unplug and examine for presence of water in the receptacle.
6. Close supervision is necessary when any pump is used by or
near children.
7. Always unplug the pump from the 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.
