IMPORTANT

A. Inspect unit for shipping damage. Report damage to car-

rier immediately.

B. Electrical supply must be a separate branch circuit with

fuses or circuit breakers, wire sizes, per national and local electrical codes.

C. ALWAYS disconnect electrical power when handling

pump or controls. Install all-leg disconnect switch near pump.

D. Motors must be wired for proper voltage. (CHECK

NAMEPLATE). Wire size must limit voltage drop to 10% of nameplate voltage at motor terminals, or motor life and pump performance will be lowered.

E. Single-Phase: Thermal protection for single-phase units is

sometimes built-in (CHECK NAMEPLATE). If no builtin protection is provided, use a contactor with proper overload. Fusing is permissible is properly fused.

F. Three-Phase: Provide three-leg protection with a proper

size magnetic starter.

lowed. Motor branch circuit must be protected by a suitable manual or magnetic starter. Proper fusing and time delay for starting must be selected to codes. Low voltage protection is recommended.

Single phase motors are dual voltage, 115/230 V, 60 Hz, A.C. All pumps are tested at the factory. At installation, correct rotation (3-phase), phase, frequency and voltage of power supply must be checked. Power lines must be of proper size to carry the amperage.

Single Phase 3 HP motors are dual voltage 115/230 V, 60 Hz, A.C. Single phase 5 HP motors are 230 V, 60 Hz, A.C. All other motors are three phase dual voltage 230/460 V, 60 Hz, A.C. The high voltages are recommended wherever available.

Three phase rotation must be checked at installation. Close, then break contacts quickly, observing rotation of exposed portion of rotating parts. Rotation must agree with arrow on pump casing. Standard rotation is counter-clockwise viewed from suction end. Motor wiring can be changed in the ﬁeld by following wiring diagram inside terminal box cover or on motor nameplate.

G. Maximum liquid temperatures: HSC & 3673 plastic

ﬁtted, 180°F (82°C) maximum. 3642-3656-3673, AI, BF, AB, 212° F (100°C) with optional high-temperature seal.

H. Regular inspection and maintenance will increase service

life. Base schedule on operating time.

INSTALLATION

Location – Locate the pump as near the liquid source as

practical (below the level of liquid storage if automatic operation is contemplated). Protect unit from cold weather or water damage due to ﬂooding. Low static lift and short, direct suction and discharge pipes are desirable. At suction lift higher than 15 ft. consult the pump performance curve for NPSHR (Net Positive Suction Head - Required). Suction pipe must be at least equal in size to suction connection of pump, and slope upward to the pump to avoid air pockets. If pipe larger than pump suction is used, an eccentric pipe reducer must be used at the pump. Gate valve in suction is necessary only on positive suction head installation and must not be used to throttle the pump.

Allow adequate room for servicing and ventilation.

Foundation – Bolt unit to foundation for easy dismantling. Foundation surface must be ﬂat so there is no distortion and/ or strain developed when tightening bolts. The pumps are quiet and smooth running, but rubber mounting is desirable on foundations susceptible to sound effect.

Alignment – No ﬁled alignment is necessary as pumps are close-coupled.

Wiring – National Electric Code and local codes must be fol-

OPERATION

Fill suction pipe and casing with liquid to be pumped to insure mechanical seal will not run dry. Four plugs are provided in the casing. In any position one will be on top for priming and/or venting and another at bottom for draining. With pump primed and motor properly wired, the unit may be started. Be sure pump is not started against a closed valve in the discharge line. Maximum temperature (212° F) limitation is imposed by the mechanical seal material. Optional high temperature seals are available.

MAINTENANCE

1. Lubrication

Pumps should require no maintenance. Motors use double-shielded ball bearings, prelubricated

for the life of the bearings. No further lubrication is required.

2. Replacing Mechanical Seal

A) Dismantling:

1. Turn off power.

2. Drain system.

3. Remove bolts holding motor adapter to foundation.

4. Remove casing bolts.

5. Remove motor and rotating element from casing, leaving casing and piping undisturbed.

6. Insert a screwdriver in impeller waterway passage. Remove impeller nut with a socket wrench (5⁄8” across ﬂats).

7. Remove impeller from shaft as follows:

a) Franklin motors: Remove motor shaft end cap. Insert a screwdriver in slot of motor shaft. While holding shaft from rotation, unscrew impeller from shaft by turning counter-clockwise when facing it. To loosen three phase and metal impellers, use a torch to apply heat to exposed shaft thread and impeller hub, as locking compound was used to secure impeller in place.

b) A.O. Smith motors: Remove motor end cover. Insert 7⁄16” open end wrench under switch mechanism onto ﬂats on motor shaft. While holding shaft from rotating, unscrew impeller from shaft. Heat may be required as indicated in 7a.

8. Pry off rotating member of mechanical seal from shaft by using two (2) screwdrivers (Fig. 1).

Figure 1

with LOCQUIC®, Primer “T” - Loctite® product Item No. 74756. (Purchase at Automotive Parts or Hardware). Let parts dry and then apply Loctite® #271 on same parts.

6. Hold shaft from rotating as described in paragraph 7 of Dismantling. Thread impeller on shaft until it is tight against shaft shoulder.

7. Apply locking compound and replace impeller nut. Hold impeller from rotating as indicated in paragraph 6 of dismantling.

8. Remove burrs caused by screwdriver on periphery of impeller in waterway passages.

9. Replace motor and rotating element in casing. Be sure to install new gasket.

10. Tighten casing bolts alternately and evenly.

11. Replace hold-down bolts.

12. Check for free rotation after assembly is complete.

13. Replace hold-down bolts.

14. Close all drain openings. Use pipe joint compound on male threads.

15. Reprime before starting. Do not start unit until pump is completely ﬁlled with water.

9. Remove bolts holding adapter to motor.

10. Place adapter on a ﬂat surface. Push out stationary parts of mechanical seal (seat and rubber mounting cup).

B) Reassembly:

1. Clean gasket and ﬂange faxes, male and female locks, seal seat counterbore and shaft, and in particular the shaft shoulder ﬁtting against impeller.

2. Lube counterbore of adapter and rubber bushing of stationary seal with water or light oil. Press stationary seat in counterbore squarely and evenly. Caution: Do not mar the lapped face of seat.

3. Remount adapter on motor. Make sure motor shaft does not dislocate stationary seat of the seal.

4. Apply a thin coat of light oil or water to motor shaft and the rubber seal member of seal. Slide rotating member of mechanical seal on motor shaft. Be sure rotating seal face stays in holding collar during installation. Take extra care not to damage the seal lapped faces.

5. Spray both shaft and metal impeller threads
