APPLICATIONThe Jabsco Electric Flush Pump will convert any Jabsco or
PAR manual toilet to electric operation. It is assembled at
the factory to fit the 29090-Series and 29120-Series toilets
which have been in production since 1987. The flush pumpassembly simply replaces the entire manual pump assemblyand screws directly to the toilet base. In addition to Jabsco& PAR toilets, the flush pump will also fit the Brydon Boy,
Mansfield (Sealand) 751, Raske & Van der Meyde RM69, andTaiwan Magnetics TMC 999 toilet models.
In order to install the Flush Pump on the following listed
toilet models, the indicated optional mounting flange must
be installed on the pump assembly.

Winner R4042C** The Wilcox Crittenden Flange Kit includes a 90° discharge elbow
and joker valve which must be used in place of the original elbow
and joker valve. The Winner toilet requires minor repositioning of
the discharge plumbing because the new discharge elbow will belower and about 4 inches further from the toilet bowl.

The pump may be installed on toilets which are mounted ashigh as 2 feet above the vessel's waterline or on toilets below
the waterline if the total cumulative discharge head does notexceed 6 feet. It will fit toilets with either a compact size bowl orlarge household size bowl. Generally, the pump requires nomodification or additions to the existing plumbing which services
the manual pump assembly. However, if the discharge hoserises and falls repetitively and the total of all rising segments(when added together) exceeds 6 feet, it should be re-routed so
the total cumulative rise is less than 6 feet. If this can not bedone, the electric flush pump should not be installed.

INSTALLATION!

WARNING

Flood hazard. If toilet is installed below thewaterline or may be below the waterline at any
angle of heel or trim, it must be installed withproperly positioned vented loops. Failure to doso can result in flooding which can cause lossof property and life.

The pump is assembled at the factory with a base mounting
flange (macerator housing) which fits the 29090-Series and29120-Series toilets. If the pump is to be installed on a PAR
59128-Series (Brydon Boy), Mansfield (Sealand) 751, Raske& Van Der Meyde RM69, Simpson Lawrence 444, orTaiwan
Magnetics TMC 999, it is necessary to replace the four holemounting flange with one of the optional mounting flanges listed
in the Application section.
To change the mounting flange, remove the four screws (onbottom of pump assembly) which secure the mounting flange tothe waste pump body. Note the relative position of the long andshort screws.

Grasp the pump body, wearplate and motor with one hand, holding
them together as an assembly. Then slide the mounting
lange/macerator housing off the pump body with the other handtrying not to disturb the wearplate and damage the paper gaskets.
It may be necessary to gently tap on the flange with a plastic mallet to start it sliding off the pump body.

Remove the screws which secure the pump assembly to thetoilet base and retain them to reattach the electric flush pump.
Remove the manual pump assembly and the base flapper
valve/gasket assembly with attached brass weight. The pumpand flapper valve may be disinfected and stowed away for
emergency use should the vessel lose electrical power.

If the gaskets are damaged, they should be replaced with newones (provided) before attaching the new mounting flange/macerator housing. To do this insert a blunt rod dowel into the dischargehole in the pump body and push it against the impeller to preventthe motor shaft from turning. Unscrew and remove the chopperfrom the motor shaft. Lift the wearplate and gaskets from the pumpbody and clean any paper residue which may stick to thewearplate and body. Reassemble with new gaskets by reversing
the procedure.

Before assembling the electric flush pump to the toilet base,attach the discharge elbow, flange and joker valve to the flushpump discharge. Position the new pump base gasket (provided)on the toilet base. Align the flush pump mounting flange with thetoilet base and secure it with the pump mounting screws.

Before assembling the new mounting flange/macerator housing to
the pump body, ensure the discharge port O-Ring is properly positioned in the O-Ring groove of the pump body. Secure the flange tothe pump body with the two shorter screws and the pump assembly to the motor with the two longer screws.
Before removing the manual pump, flush the toilet for sufficient
time to ensure all waste is thoroughly flushed from the dischargehose.
Remove the 3/4" inlet hose and toilet bowl link hose from the manual
pump. Detach the discharge elbow, flange and joker valve assemblyfrom the pump cylinder. It should not be necessary to remove the discharge hose from the elbow.
!

WARNING

Flood hazard. Close inlet and outlet
seacocks prior to disassembling toilet.
Failure to do so can result in flooding
which can cause loss of property and life.

Attach the 3/4" inlet hose to the inlet port (beneath the upper
pump pointing down). Do not connect the pump inlet to a pressurized water system. Attach the bowl link hose to the flushpump discharge port (rear of upper pump pointing back). If thebowl link hose is not long enough or is kinked, replace it with thelength of hose provided with the flush pump kit.
If the toilet is positioned below the waterline or may be below thewaterline at any angle of heel or trim, the plumbing must include
vented loops positioned above the waterline. To do this, remove
the length of hose which connects the flush pump with the bowl.
In its place install a length of hose long enough to connect theflush pump to a vented loop fitting positioned a minimum of 8inches above the waterline. Connect the other side of the vented
loop fitting to the bowl inlet elbow.
In below waterline installations with the discharge hose connected to a thru-hull fitting, the hose must rise up and be connected
to a vented loop positioned a minimum of 8 inches above thewaterline and then continue on to the discharge seacock. The
total rise of the discharge hose, however, must not exceed 6 feetof head. If a vented loop fitting in the discharge hose positioned
at least 8" above the waterline results in a total discharge headthat exceeds 6 feet, the electric flush pump should not be
installed.

WIRING
VENTED LOOP ILLUSTRATION

The flush pump should be wired to the power source with anelectrical circuit independent of all other accessories. The total
length of wire should be kept to a minimum and the wire should
be sized in accordance with the following electrical specifications
chart. The wires, if not run through a conduit, should be supported every 18 inches with non-metallic clamps.

NOTICE: Correct wire size and secure wire connections arevery important. Undersized wire and unsecured or corroded
wire connections will cause a reduction in pump performanceand possible pump failure.
The entire circuit should be protected by an appropriate
size circuit breaker or switch panel located as close to thepower source as possible.
Connect the red motor lead to positive and the black
motor lead to negative. When making connections to themotor leads use only mechanical locking (crimp type) connectors or equivalent and seal the connection with silicone orheat-shrink tube to protect it from corrosion.

4. Remove the O-Ring around the discharge port.

NOTICE: Do not run pump dry for more than ten seconds. To do so may result in damage to the pumpimpeller.

5. Grip the flat of the shaft where it has been exposed by theremove top pump assembly to prevent it from rotating.
Unscrew and remove the chopper and its lock washer.

To flush the toilet simply turn the large flush control knob
clockwise to the flush position. In the flush position theflush Pump provides rinse water to the bowl while thewaste pump simultaneously macerates and discharges
the waste. Hold it in the flush position long enough toevacuate all waste.

6. Remove the wearplate and two gaskets from thepump assembly.

To evacuate liquid from the bowl so it will not slosh while
underway, turn the flush control knob counterclockwise tothe drain position. In the drain position the flush pump will
lower the liquid level to the bottom of the china bowl while
incoming rinse water is reduced to a minimum.

7. Remove the pump body and impeller from the motor
then withdraw the impeller from the body.
8. Through the impeller bore side of the pump housing, pushevenly against the shaft seal to press it out of the bore.
WASTE PUMP REASSEMBLY:
1 .Press the lip seal into the seal bore of the pump bodywith the open side of the seal facing the impeller bore.

If the toilet bowl is empty, a small amount of water may
be added to the bowl prior to use by turning the flush control knob to the flush position.

2. Lubricate the impeller bore of the body and the motor
shaft with petroleum jelly then slide the pump body
onto the shaft.

The waste pump is designed to handle waste and toilet
tissue (either household type tissue or Marine/RV watersoluble tissue is acceptable) but it will not handle sanitarynapkins, tampons or hard solid objects.

3. Slide the impeller onto the shaft and with a counter-clockwise motion push the impeller into the impeller bore.
