• Maximum Liquid Temperature: 160ºF (71ºC)
• Maximum Starts per Hour: 20 – evenly distributed
PIPING
• Pump MUST be installed horizontally on a solid flat
surface, with discharge on top.
• Allow adequate space for servicing and ventilation.
Protect the unit from weather and water damage due
to rain or flooding or freezing temperatures.
• Piping should be no smaller than the suction and dis-
charge connections and kept short as possible, avoiding
unnecessary fittings to minimize friction losses.
• All piping MUST be independently supported and
MUST NOT place any piping loads on the pump.
NOTICE: DO NOT FORCE PIPING INTO PLACE AT
PUMP SUCTION AND DISCHARGE CONNECTIONS.
• All pipe joints MUST be airtight.
• The use of Teflon
mended for ALL pipe joints.

tape, or equivalent, is recom-
• Total suction lift, including elevation and pipe friction
loss, should not exceed 25 feet of head.
• Install an airtight union in the suction line close to the
pump. See Figure 1.
• Installation of a foot valve at liquid source is recom-
mended.
NOTICE: FOR INSTALLATIONS WITH LONG SUC-
TION PIPING, BOTH A FOOT VALVE
AND A CHECK VALVE ARE RECOMMENDED.
• To avoid air pockets, no part of the piping should be
above the pump suction connection and piping should
slope upward from liquid source.
,
• For installations with long suction piping, fill the suc-
tion pipe with water before connecting to pump.
DISCHARGE
• Install a tee at the discharge connection of the pump.
The top opening of the tee is required for initial priming. See Figure 1.

WIRING AND GROUNDING
Install, ground and wire according to local and National
Electrical Code requirements.
Install an all leg electrical power
disconnect switch near the
pump.
Disconnect electrical power
before installing or servicing
pump.
Electrical supply MUST match pump’s nameplate specification. Incorrect voltage can cause
fire or damage to the motor and voids warranty.
Motors without built-in protection MUST be
provided with contactors and thermal overloads for single phase motors, or starters with
heaters for three phase motors. See motor
nameplate.
• Follow motor manufacturer’s wiring diagram on the
motor nameplate or terminal cover carefully.
• Use only copper wire to motor and ground. The
ground wire MUST be at least as large as the wire to
the motor. Wires should be color coded for ease of
maintenance.
• Three phase unit rotation may be checked by removing
motor end cap or plug and observing rotation of motor
shaft. To reverse rotation, reverse any two of the three
motor leads.
OPERATION
OPERATION WITHOUT PRIME, OR
AGAINST A CLOSED DISCHARGE
VALVE, CAN GENERATE HOT WATER OR STEAM CAUSING INJURY
OR PROPERTY DAMAGE.
NOTICE: DO NOT OPERATE PUMP
WITHOUT PRIME OR
SEAL DAMAGE WILL
RESULT.
• Prime pump by filling pump and piping through open-
ing in top of tee with clean water. See Figure 1.
• Install pipe plug in top of tee using Teflon
™
tape or
equivalent.
NOTICE: IF PUMP IS DRAINED OR SHUT OFF
DURING PRIMING PERIOD, CASING
MUST BE REFILLED BEFORE RESTARTING PUMP.
• Start the pump and partially open discharge valve and
wait for system pressure to stabilize. If system pressure
is surging, or prolonged pressure drop is experienced,
the system may not be completely primed.
MAINTENANCE
FAILURE TO DISCONNECT ELECTRICAL POWER BEFORE ATTEMPTING ANY MAINTENANCE CAN
CAUSE SHOCK, BURNS OR DEATH.
• No lubrication is required on pump.
For motor lubrication, refer to and
follow manufacturer’s instructions.

SEASONAL SERVICE
• To REMOVE pump from service, remove all drain
plugs and drain all piping.
• To RETURN pump to service, replace all drain plugs
using Teflon™ tape or equivalent.

1. Remove foot bolt (10).
2. Remove casing bolts (12).
3. Remove back pull-out assembly from casing (2).
4. Remove diffuser seal ring (3) and diaphragm (4).
5. Remove diffuser screws (5) from adapter (11).
6. Remove motor end plug or cover.
7. Restrain motor shaft from rotation by utilization of
the screwdriver slot, or 7⁄16" shaft flats, accessible at
the motor shaft end.
8. Remove impeller (7), turning COUNTER-CLOCKWISE.
9. Using two screwdrivers, pry off rotary section of
mechanical seal (8). Discard. See Figure 2.
10. Remove motor adapter bolts (12) and remove motor
adapter from motor.
11. Push stationary seat of mechanical seal out of motor
adapter. Discard seal seat.
4. Fully and squarely install the seal rotary assembly
against the stationary seat. Be sure rotating seal face
does not drop out of holding collar and DO NOT
damage seal face.
5. On three phase units, impeller MUST be installed
with LOCTITE® “Purple”. Hold shaft from rotating,
as explained in the “DISASSEMBLY” section of the
manual, and install impeller by turning CLOCKWISE
until tight against motor shaft shoulder.
6. Replace diffuser. Align to prevent impeller rub.
7. Install new diaphragm and new diffuser seal ring.
