5. START-UP

A WARNING: NEVER run pump dry! Running the pump
dry may damage seals, causing leakage or flooding! Fill
the pump with water before starting the motor. It is an
above ground pool pump and cannot self-prime. Fill the
pump with water before starting.
• Always STOP THE PUMP before and RELEASE ALL
PRESSURE from the pump and the piping system
before proceeding.
• NEVER tighten or loosen screws while the pump is
operating.
• Do not block pump suction.
A WARNING: Do not block pump suction! To do so with
body parts may cause severe or fatal injury. Children
using pool must ALWAYS have close adult supervision.
Priming Pump
• Release all air from the filter and piping system (see
filter instructions below).
• In a flooded suction system (water source higher than
pump) the pump will prime itself when the suction
and discharge valves are opened.
• If the pump is not in a flooded suction system,
unscrew and remove the trap cover, then fill the trap
and pump with water.
• Clean and inspect the O-Ring. Re-install it on the trap
cover.
• Replace the trap cover on the trap; turn clockwise to
tighten the cover.
NOTE: Tighten the trap cover by hand only. Priming
time will depend on the vertical length of suction lift and
the horizontal length of the suction piping.

6. GENERAL MAINTENANCE

A WARNING: To prevent damage to the pump and for
proper operation of the system, clean the pump strainer
and skimmer baskets regularly.
The only routine maintenance needed is inspection and
cleaning of the trap basket (pre-filter basket). Debris or
trash that collects in the basket will restrict water flow
through the pump. Follow the instructions below to clean
the trap.
1. Stop the pump, close the suction and discharge gate
valves, and release all pressure from the system
before proceeding.
2. Unscrew the trap lid (pre-filter lid) by turning
counterclockwise.
3. Remove the strainer basket and clean it. Be sure
all holes in the basket are unclogged, then flush the
basket with water and put the trap (pre-filter) back

into position with the large opening facing the pipe
connection port. If the basket is replaced backwards,
the cover will not fit on the trap body.
4. Clean and inspect the lid.
5. Clean the O-ring and its groove on trap body (pre-
filter) and replace the lid. To help keep the lid from
sticking, tighten by hand only.
6. Prime pump (see priming instructions above).

Winterizing

CAUTION: The pump must be protected when
A
freezing temperatures are expected. Allowing the pump
to freeze will cause severe damage. Such damage will
not be covered under warranty.
There are two options when winterizing the pump.
Option 1
1. Drain all the water from the pump, system equipment,
and piping.
2. Remove the drain plugs. Do not put plugs back on.
Store the plugs in the empty strainer basket for winter.
3. Keep the motor covered and dry.
Option 2
1. Drain all the water from the pump, system equipment,
and piping.
2. Remove the pump and motor from the plumbing lines
and store indoors in a warm and dry location.
NOTE: When the winter season is over the pump
will need to be primed prior to start. Refer to Start-Up
instructions.
A CAUTION: DO NOT run the pump dry. If the pump
is run dry, the mechanical seal will be damaged and
the pump will start to leak at the seal. If this occurs,
the mechanical seal will need to be replaced. ALWAYS
maintain the proper water level in the pool. Continued
operation with low water level could cause a loss of
water pressure, resulting in damage to the pump casing,
impeller, and mechanical seal. Such damage will not be
covered under warranty.
