INSTALLATION AND OPERATING INSTRUCTIONS
HAYWARD POOL PRODUCTS, INC.
900 FAIRMOUNT AVENUE, ELIZABETH, NEW JERSEY 07207
Your Hayward centrifugal pump has been quality-built
and engineered to give you efficient, dependable service.
Additionally, it may be equipped with optional union
connectors to make installation and future service easier.
The advanced design permits use of either single or dual
speed motors and reduces operation and maintenance
to simple, common-sense procedures.
GENERAL TIPS ON PUMP INSTALLATION
The Power-Flo UN pump must be installed below
water level. For best pump performance, locate the
system below the pool water line as close to the tub
as possible. Make sure suction joints are tight.
Suction pipe should be as large or larger than
discharge pipe.
Damp, non-ventilated locations should be avoided.
Motors require free circulation of air to aid in cooling.
Insure that the electrical supply available agrees
with the motor’s voltage, phase and cycle, and that
wire size is adequate for the HP (KW) rating and
distance from power source. Motor must always be
properly grounded. If cord is connected, use a
properly grounded outlet. Electrical circuits must be
protected by proper size ground fault circuit
interrupter (GFCI) as required by applicable
electrical codes. All electrical wiring must be
performed by qualified personnel, and must
conform to local codes and regulations.
MAINTENANCE
Hayward pumps have self-lubricating motor
bearing and shaft seals. No lubrication is
necessary.
Keep motor clean. Insure air vents are free from
obstruction.
Occasionally, shaft seals must be replaced, due
to wear or damage. See instructions.
STARTING INSTRUCTIONS
Be sure water can move freely to and from the
pump inlet and outlet. Never operate the pump
without water. Water acts as a coolant and lubricant
for the mechanical shaft seal.
Turn on pump. If pump will not start, see TROUBLE
SHOOTING GUIDE on back page. Refer to tub
manufacturer’s instructions.
NOTE: ANSI/NSPI-4 Article V, standard for
above-ground and on-ground pools, advises
that components such as the filtration system,
pumps and heater be positioned so as to
prevent their being used as a means of access
to the pool by young children.
CAUTION: All suction and discharge lines must
be open when starting the system. Failure to do
so could cause severe personal injury and/or
property damage.
STORAGE/WINTERIZING
Pump and motor must be protected from freezing. If
freezing temperatures are expected, be sure all
water has been drained from tub, piping and pump.
Shut off all electric power at circuit breaker or main
service panel.
