Receiving Inspection
Upon receiving the pump, it should be
inspected for damage or shortages.
If damage has occurred, file a claim
immediately with the company that
delivered the pump. If the manual is
removed from the packaging, do not
lose or misplace.
Storage
Any product that is stored for a period
longer than six (6) months from the
date of purchase should be bench
tested prior to installation. A bench
test consists of, checking the impeller
to assure it is free turning and a run
test to assure the motor (and switch
if provided) operate properly. Do not
pump out of liquid.
Location
The design of these pumps allow for
use in decorative water displays. These
pumps should be set in the bottom
of a pit in the horizontal position to
insure submergence at all times. In the
horizontal position, the built-in suction
trap will prevent the unit from pumping
the pit dry, keeping the motor 2/3
submerded, providing adequate cooling.
Pump may be mounted in the vertical
position, but could expose motor
housing if water level is pumped down.
This could cause the motor to overheat
and trip the built-in automatic overload
protector.
Discharge Piping
This is a high capacity low head pump.
It is important to use as few pipe fittings
as posible and of adequate size to
hold pressure loss due to friction to a
minimum. All models have 1-3/4 inch
hose connection discharge and can be
rotated in 90° increments.
WARNING ! - Disconnect power
from pump before handling
or servicing Injury, electrical
shock or death could result.
Pump MUST be grounded in
accordance with the NEC or
CEC and all state province,
local codes and ordinances.
This pump is NOT for use in
swimming pools.
Electrical Connections
The PFU motor is an oil filled, single
phase permanent split capacitor
type with built in automatic overload
protector and does not require a control
box. Connect the white and black wires
of the motor lead to the two line leads
from the power source fused disconnect
switch or breaker box. Connect the green
wire to a ground. See table below for,
cable sizes to reach from power souce to
motor leads, and fuse sizes.

Power cable:
The power cable mounted to the pump
must not be modified in any way except
for shortening to a specific application.
Any splice between the pump and the
control panel must be made in
accordance with the electric codes. It is
recommended that a junction box, if
used, be mounted outside the sump
to prevent flooding.
DO NOT USE THE
POWER CABLE TO LIFT PUMP.
Overload Protection:
Single Phase
- The stator in-winding
overload protector used is referred to
as an inherent overheating protector
and operates on the combined effect
of temperature and current. This means
that the overload protector will trip out
and shut the pump off if the windings
become too hot, or the load current
passing through them becomes too high.
IMPORTANT ! -
The overload will then
automatically reset and start the pump
up after the motor cools to a safe
temperature. In the event of an overload,
the source of this condition should be
determined and corrected immediately.
WARNING! - DO NOT LET THE
PUMP CYCLE OR RUN IF AN
OVERLOAD CONDITION
OCCURS !
If current through the temperature sensor
exceeds the values listed, an intermediate
control circuit relay must be used to
reduce the current or the sensor will not
work properly.
