IMPORTANT SAFETY
INSTRUCTIONS
When installing and using this
electrical equipment, basic safety
precautions should always be
followed, including the following:
READ AND FOLLOW ALL
INSTRUCTIONS
WARNINGS
1. To reduce the risk of injury, do
not permit children to use this
product unless they are closely
supervised at all times.
2. Do not bury cord. Locate cord to
minimize abuse from lawn
mowers, hedge trimmers, and
other equipment.
3. Risk of electric shock. Connect
only to a grounding type
receptacle protected by a Ground
Fault Circuit Interrupter (GFCI).
Contact a qualified electrician if
you cannot verify that the
receptacle is protected by a
GFCI.
4. To reduce the risk of electric
shock, replace damaged cord
immediately.
5. To reduce the risk of electric
shock, do not use an extension
cord to connect unit to electric
supply; provide a properly
located outlet. For runs greater
than 6 feet, consult your local
licensed electrical contractor.
6. To reduce the risk of electric
shock, make sure you and your
clothing are dry before touching
your filter or pump. Make sure
the ground under your feet is dry.
7. To reduce the risk of electric
shock, do not install your pump
or filter on a deck. They could fall
into the water causing severe
electric shock or electrocution.
Do not install on any surface at,
above, or slightly below the top
rail or water line of the pool.
8. Do not allow children or adults to
climb sit or stand on your pump
or filter. They could easily fall
and injure themselves. Install the
filter and pump a minimum of 4
feet from the pool wall so they
may not be used as steps by
children.
CAUTIONS
1. Do not install pump and filter
system where flooding may
occur. This could damage the
pump motor.
2. Make sure the pump is
disconnected from electrical
source before servicing pump
and filter equipment.
3. Never run the pump without
water. Water acts as a coolant
and lubricant for the pump seal.
If the pump is run dry, the seal
will be damaged.
4. SAVE THESE INSTRUCTIONS.
LOCAL CODES
Contact your local building
department for applicable codes or
regulations governing the installation
of swimming pool equipment.
CONTRACTED
ELECTRICIANS
Always have a licensed electrician
install electrical components to make
sure electrical integrity is maintained
in accordance with the pump data
label. Improper installation to the
power supply may damage the pump
motor.
ELECTRICAL FEATURES
Your pump is supplied with a 6-foot,
3-wire electrical cord and 3-pronged
plug. The pump electrical cord must
be connected to a grounded, 3-wire,
115 VAC electrical receptacle. The
receptacle must be protected by a
Ground Fault Circuit Interrupter (GFCI)
An ON/OFF switch must be installed
at the receptacle.
IMPORTANT
INSTRUCTIONS
If you have purchased a Lomart
filtration system, follow the
instructions provided with your Lomart
Filter instructing you to prepare the
filter and pump foundation using patio
blocks and a level.
PUMP ASSEMBLY
Position the pump near the filter to
allow for convenient routing of the
filter and pump hoses.
INITIAL START-UP
1. If you have a Lomart filtration
system, follow the "Initial Start-
Up" instructions in the Lomart
Filter owner's guide.
2. The pump will have to be primed
after all hose connections have
been made and the pool has
been filled to the proper level. To
prime the pump, fill the hoses and
pump chamber with water from a
garden hose. Be sure to tighten
all hose connections before
starting the pump motor.
3. Turn on the pump motor.
4. Allow a reasonable amount of
time (a few minutes) for the
system to be completely purged
of air.
MAINTENANCE &
WINTERIZING
Make sure the pump is discon-
nected from the electrical source
before attempting any maintenance
work.
Drain all water from the pump system
