INSTALLATION
Macerator Pump Model 406M can be configured to run in either
rotation. However once the configuration is set, it becomes a unidirectional pump. Given the macerator feature, the pump will not
function in both rotating directions during operation. Model 405M
can be converted to 406M using macerator conversion kit 10827.
Vacuum Switch Option is intended to be used as a safety device
to protect pump and motor from damage caused by dry running
conditions. Switch must be mounted on the suction side of the
pump in order to sense a break in vacuum. Pump housing has
properly positioned convenient connection points for this purpose. When the switch senses vacuum falling below 1 1/2" mercury, it will open/break the power circuit to the single-phase 115V
/230V AC motor.

Caution: For DC motor operation, the Vacuum Switch is only rated
32-115-230V up to 1/2 HP. It is not designed for direct use with 1 HP
12VDC or 1 HP 24 VDC motors.
For Three Phase motors, the
vacuum switch must be wired, using a control circuit to actuate an
independent relay. Do not attempt to use the switch to disrupt two of
three power legs directly to three phase motors.
Suction Plumbing considerations are important to assure adequate
fluid flow to the pump. Avoid collapsed or kinked hose conditions by
using pipe or reinforced hose. Avoid unnecessary bends or elbows.
Pump Heads with Vacuum Switch (406MK-04) are Factory supplied
with Vacuum Switch mounted in the
"Factory Supplied" CCW rotation orientation shown on pg.3. If reverse
rotation is desired, follow the diagram to reposition the switch 14 ,
pipe nipple 15, pipe plug 16, pick
screw 27, port plug 17, and plate 20.
Note that there is a notch in plate 20
that is always oriented towards discharge. Follow instructions for
mounting pump head to motor and
the wiring diagram to interface the
vacuum switch.
406MK-04N26 is supplied in the "Factory Supplied" CCW rotation orientation shown on pg.3 and with the vacuum switch prewired to the 1
HP motor for 115 V operation. A convenient 8 ’ long power cord and
plug is provided.

Motor Mounting: Pump heads are supplied with adapters and
coupling hardware to directly attach to Nema 56C frame motors.
Attach the adapter 3 to the motor with (4) bolts 4. Place collar 5
loosely over pump shaft 7 aligning the collar setscrew over the keyway slot. Loosen clamp bolt 15.
Setting Mechanical Seal Compression:
Set the motor on its base on the edge of a firm flat surface with the
shaft key oriented upwards. While holding the pump head upside
down, orient the pump shaft keyway slot to the window and clamp
slot for easy viewing and collar access. With the pump still inverted, gradually slide pump head onto the adapter bracket hub and
onto the motor shaft taking care to align keyways. Place edge of
key 6 into shaft 3 key slot. With the help of a flathead screwdriver
held against the rear of key 6, continue to slide pump head onto
motor shaft until key drops fully into position, engaging motor shaft
to pump shaft. Slide pump head towards adapter -but do not fully
shoulder. Rather, leave 0.030" to 0.050" of gap between adapter
shoulder and pump body. Slide collar 5 further on shaft 7 and over
key 6. Tighten collar set screw directly over key.
Rotate pump head 180 degrees from the inverted position to the
standard upright position. Slide pump head further onto adapter
bracket until it shoulders fully. Tighten clamp bolt 15.
OPERATING INSTRUCTIONS
5) Freezing temperatures - drain the unit by loosening (4) cover
screws 24 and loosening plate 20. Retighten and fill the pump
chamber with a methyl alcohol based anti-freeze (compatible
with neoprene impeller). Do not use petroleum-based antifreeze.
SERVICE INSTRUCTIONS
Wet End Repair Kit 10956 contains impeller, seal, and gasket
Vacuum Switch Repair Kit 10798 contains switch, pipe nipple,
and power cord
WARNING: Before attempting disassembly and service, disconnect motor power and release all pressure within the system. Failure to disconnect and lockout electrical power before
attempting any maintenance can cause severe personal injury.
Disassembly
Impeller changing:
1) Remove (4) cover screws 24 and cover 23
2) Remove shaft screw 22, macerator wheel 21, plate 20,
gaskets 19, and key 9
3) Pry impeller 18 out of body 13 using 2 screw drivers
PRE START-UP
WARNING: Before attempting disassembly and service, disconnect motor power and release all pressure within the system.
Failure to disconnect and lockout electrical power before attempting any maintenance can cause severe personal injury.
1) Rubber impellers may stick to inner wall of pump body when
units have been in dry storage for extended periods. In this case,
remove plug 17 from pump and add lubricant to the inside of the
pump body. In rare instances, it may be necessary to remove
cover 23 to free the shaft manually by turning the macerator wheel.
2) On initial start-up, prime the pump to prevent dry-running the
impeller. For units equipped with Vacuum safety switch, push
down the start/restart lever and hold until the pump is primed and
operating.
START-UP and RUNNING
3) On subsequent starts, as long as the impeller remains wet,
pump is self-priming with suction lifts of 15 feet possible.
Caution: DO NOT RUN DRY for more than 30 seconds. Lack of
liquid will damage impeller.
4) Caution: When the pump is operated against a clogged suction
strainer in a fluid starved condition, there may still be adequate
vacuum present to keep switch contacts closed (for units with
optional vacuum switch). Keep suction strainer clean to retain
switch protection.

Shaft Seal changing:
4) Remove shaft key 8
5) Loosen screw 12 and remove pump body 13 from adapter
6) Press seal head 11 out of pump body and slide wear face
(with seat) off pump shaft.
Reassembly
7) Slide new wear face (with seat) onto pump shaft to shoulder
position
8) Press new seal head into pump body 1/16 below surface
using Loctite, Permatex or similar sealant between seal OD
and housing bore.
9) Reassemble pump onto adapter. Tighten screw 12
10) Install key 8 into pump shaft and push new impeller 18 on
shaft 7 into pump body 13
11) Install (1) gasket 19 and plate 20 loosely against pump
body face 13.
12) Install key 9 and macerator wheel 21 onto shaft. Secure
with screw 22 using Loctite 222.
13) Place second gasket against outer face of plate 20.
Carefully position kidney-shaped opening in plate 20 relative to
pump body consistent with the desired rotation and outlet direction. See diagram below.
14) While holding plate 20 and gaskets 19 (one on each side of
plate 4) in position, attach cover 24 with (4) screws 24. Tighten
screws securely.
15) Check and reset mechanical seal compression following
instructions above.
