To Check for Proper Rotation: Remove the motor end cover. This
exposes 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.
WARNING - RISK OF ELECTRICAL SHOCK
GROUNDING THE MOTOR: WIRING TO THIS PUMP MUST
BE INSTALLED AND MAINTAINED IN ACCORDANCE WITH
THE NATIONAL ELECTRICAL CODE OR YOUR LOCAL
WARNING:
DO NOT RUN THE PUMP BEFORE PRIMING IT, SINCE THE SEAL AND IMPELLER COULD BE PERMANENTLY DAMAGED.
PRIMING THE PUMP: A priming plug is provided in the top of
the casing to fi ll the pump with water. Once fi lled 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 fi lling 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 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
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.
WARNING - RISK OF ELECTRICAL SHOCK
• Have an electrician provide electrical power to the motor.
• Motor must be grounded and terminal cover in place to
reduce electrical shock hazard.
• Keep motor operating area as dry as possible.
• A ground fault interrupter (GFI) protected circuit is recom-
mended for use with any electrical device operating near
water.
• Always disconnect power before servicing.
• Not investigated for use in swimming pool areas.

POWER COMPANY.
It is recommended that a permanent ground connection be made to
the unit using a conductor of appropriate size from a metal under-
ground 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.

of water (make sure that the suction line is also devoid of water).
STORAGE OF PUMP: Drain liquid from pump to prevent freez-
ing. It is recommended that a good rust inhibitor be put in the
liquid end to prevent excessive corrosion.
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.

a) The pump requires no lubrication.
b) For electric motor models, refer to instructions provided
by the motor manufacturer.
1) Shut off the power to the pump at the main service panel
and disconnect the power supply from motor.
2) Open a tap in the water system to release the pres-
sure.
3) Remove the drain and fi ll plugs to allow the pump to
drain.
4) Remove the four bolts (11) and remove casing (1).
5) Remove three screws to separate diffuser (3) from mo-
tor adapter (2).
6) Remove cap (5) and insert a screwdriver to prevent the
shaft from turning while unscrewing the impeller (4).
