Operation - STA-RITE DYNA-PRO MPRA Series Owner's Manual

Pump must be permanently connected to circuit. Table
I, Page 7, give correct wire and circuit breaker sizes for
the pump alone. If other lights or appliances are also on
the same circuit, be sure to add their amp loads to
pump amp load before figuring wire and circuit breaker
sizes. (If unsure how to do this or if this is confusing,
consult a licensed electrician.) Use the load circuit
breaker as the master on-off switch.
Install a Ground Fault Circuit Interrupter (GFCI) in
circuit; it will sense a short-circuit to ground and
disconnect power before it becomes dangerous to pool
users. For size of GFCI required and test procedures for
GFCI, see manufacturer's instruction.
In case of power outage, check GFCI for tripping (which
will prevent normal pump operation). Reset if
necessary.
NOTICE: If you do not use conduit when wiring motor,
be sure to seal wire opening on end of motor to prevent
dirt, bugs, etc., from entering.
Risk of
dangerous or
fatal electrical shock. Be
sure that power to the motor
circuit is off before working
on wiring, wiring
connections, or motor. Re-
install the motor end cover
and all other wiring covers
before turning on the power.
1. Turn off power.
2. Remove the motor end
cover.
To Wire a Single Speed,
Single Voltage Motor
There are two terminals
labeled L1 and L2. Attach the
power leads to these terminals.
Either wire may attach to either terminal.
To Wire a Dual-Voltage Motor
Dual voltage motors have a plug to change from 230
volts (factory setting) to 115 volts.
1. If you have 230 volts motor supply voltage, confirm
that the plug is set for 230 volts. The arrow on the
plug will point to the 230 volt position. Note that plug
only connects with one prong in this position.
2. If you have 115 volt supply, pull the plug straight up
and place it on the two brass prongs as shown.
NOTE: Arrow is highlightedfor clarity.
To Wire a Two-Speed Motor
Wire the pump as shown in the diagram on page 6.
Hazardous voltage.
Can shock, burn,
or cause death.
Disconnect power
before working
on pump or motor.
OPERA TION
DO NOT run the pump dry. If the pump is run dry,
the mechanical seal will be damaged and the pump
will start leaking. If this occurs, the damaged seal
must be replaced. ALWAYS maintain proper water
level. If the water level falls below the suction port,
the pump will draw air through the suction port,
losing the prime and causing the pump to run dry,
resulting in a damaged seal. Continued operation in
this manner could cause a loss of pressure,
resulting in damage to the pump case, impeller and
seal and may cause property damage and personal
injury.
Before removing trap cover:
1. STOP PUMP before proceeding.
2. CLOSE GATE VALVES in suction and discharge air.
3. RELEASE ALL PRESSURE from pump and piping
system.
If pump is being pressure tested, be sure pressure
has been released before removing trap cover.
Do not block pump suction. To do so with body
may cause severe or fatal injury. Small children
using pool must ALWAYS have close adult supervision.
Fire and burn hazard. Modern motors run
at high temperatures. To reduce the risk of fire, do not
allow leaves, debris, or foreign matter to collect around
the pump motor. To avoid burns when handling the
motor, let it cool for 20 minutes before trying to work on
it. An automatic internal cutoff switch protects the motor
from heat damage during operation.
NOTICE: Maximum ambient temperature for motor
operation must not exceed maximum ambient
temperature on motor nameplate.
Priming Pump
Release all pressure from filter, pump, and piping
system; see the filter owner's manual.
In a flooded suction system (water source higher than
pump), pump will prime itself when suction and
discharge valves are opened.
If pump is not in a flooded suction system, unscrew and
remove trap cover; fill trap and pump with water.
Clean and inspect O-Ring; reinstall on trap groove.
Do not lubricate the trap cover O-Ring. The original
equipment O-Ring contains a permanent internal
lubricant.
NOTICE: If you replace the
O-Ring with a non-internally lubricated O-Ring, you may
need to apply a silicone based lubricant.
