Raritan 53 Operating instructions

1
THE FOLLOWING ARE CAUTIONARY STATEMENTS THAT MUST BE READ AND
FOLLOWED DURING BOTH INSTALLATION AND OPERATION
WARNING: Raritan Engineering Company, Inc. Recommends that a qualied person or electrician install this
product. Equipment damage, injury to personnel or death could result from improper installation.
Raritan Engineering Company, Inc. accepts no responsibility or liability for damage to equip-
ment, or injury or death to personnel, that may result from improper installation or operation of
this product.
WARNING: RISK OF SHOCK OR FIRE - If the pump is operated in an area containing ammable vapors, the
wire leads must be joined by insulated mechanical locking connectors. Loose or inadequate wire
connections can spark, resulting in an explosion resulting in property damage, injury, or death.
Always use recommended fuse/circuit breaker and wire size.
WARNING: Hazard of Flooding - Any installation made below the waterline must have vented loops posi-
tioned properly and all hose connections should be double-clamped. Both intake and discharge
seacocks should always be in the closed position when the toilet is not in use. Failure to do so
may result in ooding, property damage and loss of life.

OPERATION
Designed to empty marine and RV holding
tanks of normal waste and sh boxes of scales
and residual waste. The unique dual-cut blade
design ensures waste is ground up thoroughly.
Marine pump out must be in proper discharge
zones only. This macerator will not handle hard
objects, rags, or feminine napkins.
e optional Smart Macerator Control (SMC)
monitors pump motor and prevents pump
damage due to priming failure or dry running.
It also protects motor against overload. If power
to control is not turned o, smart control will
prevent impeller sticking by jogging impeller
once every seven days of non- use.
PUMP IS INTERMITTENT DUTY ONLY!
• Make sure Waste valve to pump and discharge
valve [if equipped] are both open. Turn on
momentary switch and pump out tank.
• When tank is empty, pump will get louder
with a high pitch sound. Immediately turn
pump o, or damage to impeller and housing
will occur. If pump is equipped with SMC,
pump will turn o after 5 seconds of dry
running
• If not equipped with SMC, do not run pump
dry for more than 15 – 20 seconds. Flush
tank and pump with water after each use.
This macerator will handle normal waste,
tissues, cigarettes, sh scales, etc. It is not
designed to handle large hard objects such as
large bones or fruit pits.
Periodic Maintenance and Storage: Flush
with water after each use. Check wire connec-
tions occasionally. After periods of non-use,
impeller can stick. To loosen, open rear shaft
cover and turn motor shaft clockwise with a at
tip screwdriver. Then replace shaft cover. For
extended periods of non-use, pump impeller can
be lubricated by running a small amount of min-
eral oil through holding tank system.
Maintenance: Turn o all power!
Rear end cap/ motor shaft slot access:
Remove cap over the shaft
Smart Macerator Control (SMC) (optional)
SMC monitors motor and pump to prevent dry
run and overload.
Turn on switch (ESR03A) to activate Macerator
Pump.
SMC control has following features:
1. If pump does not prime within 7 seconds,
SMC control will shut down the pump.
2. If pumps runs dry for 5 seconds, SMC
control will shut down the pump.
3. If pump draws more than 20 amps, control
will shut down pump.
4. LED at the switch and on the board will ash
if there is shut down due to priming failure
or dry run. LED will stay on if shutdown is
due to overload. SMC control can be reset
by turning o and on switch. Power need
not be turned o.
5. If power is not turned o to the control,
control will jog macerator pump for few
milliseconds every seven days if non use to
prevent binding of impeller.
A Maintenance Tip!
Loosen stuck impeller by turning motor sha
clockwise from rear with a at-tipped screwdriver.

Installing 1 1/2" MPT
Plumbing Connections
Pump should be mounted as near as possible to
tank to minimize dry run. Pump is self-priming
to a ve-foot lift when impeller is wet, four foot
lift when impeller is dry. Pump is more ecient
if mounted near the holding tank.
INLET: For model 53100: Always install pump
with a shut-o valve between pump and holding
tank. Model 53101 includes an integral wastewa-
ter valve.
HOSE: Use 1-1/2” ID [non-collapsible vacuum
rated] hose on inlet [suction] side. Use stainless
steel hose clamps on all sanitation connections.
1 1/2" MPT: For model 53100: The 1 1/2"MPT
can be used for connecting directly to 1 1/2" FPT
tank ange or 1 1/2" FPT ttings. The inlet barb
must be cut o just before the threads
(see FIG 1). Seal threads and hand tighten.
For model 53101: Use 1 1/2" threaded nipple
between FPT ange and waste valve . Use thread
sealant to tighten joints.
WARNING: Any air leak on inlet side can
cause pump to run dry and can damage impeller
and impeller housing. Check all inlet side con-
nections, even those on deck plates. All runs
should be smooth with no kinks or sharp angles.
OUTLET: Two outlet ttings are included, 1"
barb (for 1" ID hose) and 3/4" MPT. Insert the
tting into outlet port and insert retaining clip.
Install a 1" shut-o valve between pump quick
disconnect and hose. Connect to thru-hull t-
ting above highest heeled point above waterline.
Vented loop installations must vent above highest
heeled point above waterline (see WARNING).
Use stainless steel hose clamps on all sanitation
connections.

TROUBLESHOOTING
Maintenance: If pump is not used for long
period, impeller may bind to the pump housing
causing overload. Impeller can be freed by
turning the motor shaft (FIG 8)
CAUTION: Turn o all power prior to removing
the plastic cap and rotating shaft with a screw
driver.
Note: Smart macerator control will jog the shaft
every 7 days of non-use automatically preventing
binding.
Pump disassembly:
Model 53101**:
Using a 7/16" wrench, close the inlet waste valve
by turning the shuto nut clockwise to the closed
position (FIG 9). Remove two screws (FIG 10).
Slowly, pull waste water valve away from the
pump.
Model 53100**:
Disconnect inlet hose.
All models:
Shuto discharge valve if installed.
Remove clip (13) and remove tting (10/11) .
Pump can be unbolted and removed for
disassembly to a convenient location.
Remove 4 cover screws (14). Remove housing
(19 or 17)) and O-ring (3). Remove hex nut (16)
and cutter blades (9). It may be necessary to hold
the motor shaft steady. Insert a screwdriver into
slot on motor shaft (see slot access above), or slip
a thin wrench (9/32” [7mm]) behind blades onto
at of motor shaft. Remove top wear plate (8),
gasket (7), impeller (5) and bottom wear plate (6).
Remove impeller housing (3) and shaft seal (4).
Pump reassembly:
Follow disassembly in reverse order.
Tip: Turn rubber impeller counter clockwise to
install in the housing.
