over a prolonged period of time, the suction line should be led
almost horizontally to the pump. Non-toxic thread compound
should be used on all pipe joints and connections should be
thoroughly tightened. A strainer should be connected to the
bottom end of the suction pipe and it should be well submerged
at all times.
Adhere to the guidelines of national, state and local
plumbing codes when installing this product. Check with
the appropriate agencies or water system professional for
additional information.
WARNING - RISK OF ELECTRICAL SHOCK
WIRING: Make sure the voltage and frequency of the power
supply agrees with that stamped on the motor nameplate. If
in doubt, check with the power company.
WARNING - ELECTRICAL PRECAUTIONS
All wiring, electrical connections, and system grounding must
comply with the National Electrical Code (NEC) and with any
local codes and ordinances. Employ a licensed electrician.
SINGLE PHASE: Determine incoming voltage to motor. Where
possible, use 230V. Connect wiring to terminal board located
WARNING:
DO NOT RUN THE PUMP BEFORE PRIMING IT. THE SEAL AND IMPELLER COULD BE
PERMANENTLY DAMAGED.
PRIMING THE PUMP: A priming plug is provided in the top of
the casing to Äll the pump with water. Once Älled and the priming
plug replaced, the pump will prime. The priming time depends
upon the vertical and horizontal distance between the pump and
the water level.
CAUTION:
DO NOT run the pump before Älling the pump
case with liquid, as it may damage the seal.
PRIMING UNDER PRESSURE: (Refer to Figure 1) Should it
be necessary to prime under pressure, place a check valve on
the discharge line of the pump and a pet cock or a ball type
air bleeder in place of the priming plug, or an air bleed line
with a gate valve connected to the discharge line. It will then
be possible for the liquid to remain in the discharge pipe and
allow the pump to bleed off the remaining air, thereby facilitating
priming.
IMPELLER ROTATION: The impeller must rotate in a counter-
clockwise direction as seen facing the pump from the front of the
casing. In the event of wrong rotation for electric motor models,
refer to the instructions furnished with the motor. The rotation of
three-phase motors can be changed by interchanging any two
lead wires.
STARTING THE PUMP: Never operate the pump dry as this may
damage the seal. If an exceptionally long suction line is used,
the water in the pump casing may become overheated or vapour
locked. Should this occur, replace the water in the casing with
cold water and continue priming.
DRAINING: Should the pump be subject to freezing
temperatures, it will be necessary to drain the pump completely.
To drain, remove the drain plug located at the bottom of the front
inside motor end cover. Be sure voltage connections agree with
wiring diagram on motor nameplate.
THREE-PHASE: Three-Phase motors require magnetic starters,
and can run in either direction, depending on how they are
connected to the power supply.
Check for Proper Rotation: Remove the motor end cover to
expose the motor shaft. If hookup is correct, the shaft will rotate
clockwise. If rotation is not clockwise, reverse any two leads to
the starter. The rotation will now be correct.
GROUNDING THE MOTOR: WIRING TO THIS PUMP MUST BE
INSTALLED AND MAINTAINED IN ACCORDANCE WITH THE
NATIONAL ELECTRICAL CODE OR YOUR LOCAL ELECTRIC
CODE. IF MORE INFORMATION IS NEEDED, CALL YOUR
LOCAL LICENSED ELECTRICIAN OR YOUR POWER COMPANY.
It is recommended that a permanent ground connection be
made to the unit using a conductor of appropriate size from a
metal underground water pipe or a grounded lead in the service
panel. Do not ground to a gas supply line. Do not connect
to electric power supply until unit is permanently grounded.
Connect the ground wire to the approved ground and then
connect to the terminal provided.
OPERATION - PRIMING THE PUMP
face of the pump casing and the priming plug and make sure
that the drain hole is not restricted. After all the water has been
drained, operating the pump for a few seconds will ensure that
the impeller is devoid of water (make sure that the suction line is
also devoid of water).
STORAGE OF PUMP: Drain liquid from pump to prevent
freezing. It is recommended that a good rust inhibitor be put in
the liquid end to prevent excessive corrosion. Be sure motor
is kept dry and covered. When restoring the use of the pump,
replace all plugs and make sure all connections are tightly
sealed. After a complete check is made, make the initial prime
according to directions under the section, Priming the Pump.
