Product Usage Instructions

Installation:
When installing the QuietFlush Electric Toilet, ensure the SEAFLO 52S02 strainer is securely mounted with the flow arrow pointing towards the pump. Connect the inlet hose to the strainer’sports and the discharge port to the SEAFLO rinse pump’s inlet port. Use the provided hose to connect to the back of the toilet bowl and route it out of the head area.

Vented Loop Installation:
If the toilet is installed below the vessel’s water line, install a vented loop fitting between the rinse pump and the toilet bowl to prevent siphoning. The vented loop must remain at least 6-8 inches above the waterline at all angles of heel and trim.

Electrical Specifications:
Ensure correct voltage supply and amp draw according to the specifications provided. Use appropriate fuse sizes and wire sizes per feet of run as indicated in the manual.

FAQ:

• Q: Can I use freshwater instead of seawater for rinsing?
  A: The toilet is designed to work with seawater or lake water for rinsing. Using freshwater may affect performance and is not recommended.

• Q: How do I order spare parts for the toilet?
  A: All spare parts can be ordered individually. Contact customer support or refer to the product manual for a list of available spare parts.

OPERATION

The Quiet-Flush toilet provides both quiet operation and user control of water levels in the toilet bowl. A single large push-button switch provides a simple flush mode by activating both the rinse water supply and the macerator discharge pump simultaneously. An additional rocker switch offers independent control of the rinse water supply and discharge pump separately so the bowl water level can be easily raised or lowered by the user. This provides a method of minimizing water use, when desired, as well as a means of raising the water level in the bowl when appropriate for user comfort. It also allows for complete evacuation of the bowl water while underway in rough sea conditions.

INSTALLATION

• The SEAFLO Quiet Flush Toilet is complete with a dedicated SEAFLO seawater rinse pump to provide either sea or lake water to rinse the toilet bowl when flushing the toilet. This pump is intended to be located remotely from the toilet but will function best if the distance from the toilet is kept to a min i mum. Because it is self-priming, it may be located above the vessel’s waterline. It must be installed with the SEAFLO 52S02 strainer (provided with the toilet) located somewhere in the inlet plumbing to the pump.

• The toilet also includes a multi-function flush control which should be installed in a bulkhead location that is convenient to the toilet and allows access for wiring to run from the power source and to both the toilet discharge pump and the SEAFLO rinse water pump.

• Install the toilet seat and lid assembly on the china bowl with the fasteners provided and position the toilet in its desired location. When locating the toilet, ensure there is adequate clearance above and to the rear of the bowl so the seat and lid assembly can rotate slightly past vertical so it will remain up when lifted. It is all right to rotate the waste pump assembly under the china bowl to provide clearance from possible obstructions if desired. This can be accomplished by re-moving the four white plastic hex head caps from the nuts at the base of the china bowl and removing the four machine screws and nuts that secure the china bowl to the base. The base can then be reattached to the bowl at any position in 90º increments. Once the exact position for the toilet has been determined, mark the location of the four base attachment holes on the toilet mounting surface. Determine the best toilet attachment method using 5/16″ (8 mm) fasteners (either machine screws for through bolting or lag screws for topside attachment) and drill the appropriate size holes for the fasteners being used. If securing the toilet with lag screws into a plywood underlayment below fiberglass, be sure to drill a hole through just the fiberglass layer large enough to allow clearance for the screw threads and shank to avoid cracking the fiberglass.

• SEAFLO rinse pump should be mounted to a solid mounting surface. It should be secured with four fasteners through the rubber grommets that snap into the pump’s base. Do not over-tighten the mounting screws and crush the grommets such that they will not absorb vibration. The pump may be mounted in any position; however, if mounting it to a vertical surface it should be oriented so water dripping from a loose port connection will not drip down on the motor. Plumbing runs should be kept as short and straight as possible. All plumbing should be completed with quality 3/4″ (19 mm) hose that will not collapse or kink. Route the inlet hose from a 3/4″ (19 mm) through hull and seacock fitting located well below the waterline (and well forward of any discharge through hulls, if in stalled) to the pump inlet port. Ensure the inlet hose passes through an accessible location (preferably above the vessel’s waterline) that will allow for the installation of the Toilet SEAFLO 52S02 strainer where it can be periodically inspected and cleaned of debris.

• The SEAFLO 52S02 strainer should be secured with two fasteners to a solid mounting surface with the flow arrow pointing towards the pump. The inlet hose should be cut and each end attached to the strainer’s ports. The hose from the strainer’s dis charge port must connect with the SEAFLO rinse pump’s inlet port. Provided with the toilet is a six foot length of smooth white aesthetically pleasing hose to connect to the back of the toilet bowl and be routed out of the head area. Ideally, the pump should be located so this length of hose can be connected directly to the pump’s discharge port avoiding an additional splice to the hose leading from the pump to the back of the toilet bowl. If this is not practical, acquire a 3/4″ (19 mm) barb to barb hose mender and splice the white hose to the supply hose from the discharge port of the pump.

• If the toilet is installed below the vessel’s water line, in order to prevent a siphon action from filling the toilet, a properly positioned vented loop fitting must be installed between the SEAFLO rinse pump and the back of the toilet bowl. The vented loop fitting must be secured in a location that remains at least 6-8 inches (15-20 cm)
  above the waterline at all angles of heel and trim (see diagram).

• The toilet discharge port is sized for 1″ (25 mm) hose. The discharge hose should be a quality grade reinforced hose suitable for waste applications. Route the discharge hose to the holding tank in the most direct way with as few bends as possible. To retain some water in the bowl, it is best to loop the discharge hose up about 8-10 inches (15-20 cm) as close to the toilet as practical then on to the holding tank. It is best to avoid any dips or low spots in the discharge plumbing that can act as water traps and collect waste. If this occurs, waste can solidify and cause a discharge blockage.

• If the toilet is plumbed to an over board discharge, and is below the vessel’s waterline, the discharge plumbing must include a properly positioned vented loop. The vented loop fitting must be secured in a location that remains at least 6-8 inches (15-20 cm) above the waterline at all angles of heel and trim. The maximum discharge head without a notable decrease in pump performance is four feet (1.3 M).

ELECTRICAL

• The electrical wiring should be independent of all other accessories. It should be made with marine grade copper stranded wire of the gauge specified in the electrical specifications chart. Make all wire connections with mechanical locking type connectors (crimp-type butt connectors and terminals). Ensure the circuit is protected by a properly sized fuse or circuit breaker determined from the electrical specifications chart. Secure all wires to a solid surface approximately every eighteen inches (1/2 M) along their entire length of run.
• Wire the switch panel to the rinse pump and toilet waste pump as per the following wiring diagram. The brown lead from the control panel connects with the waste pump’s red (positive) motor lead. The yellow lead from the control panel connects with the rinse water pump’s red (positive) motor lead. The black motor lead from each pump must be connected to battery negative. Select a location for the switch panel that is convenient to the toilet user and will also allow access to run the wires from the switch panel to both the toilet’s waste pump motor and the rinse pump as well as from the electrical power source to the switch panel. To install the switch panel, drill two 1-3/4″ (45 mm) diameter holes (slightly over-lapping) through the selected switch mounting surface per the attached template.
• Ensure the template is oriented correctly because it is not symmetrical. Also, drill four appropriate-sized holes for the fasteners selected to secure the switch panel to its mounting surface

WASTE PUMP SERVICE

• The SEAFLO Quiet Flush Toilet does not require routine maintenance other than occasional cleaning to maintain a hygienic sanitary condition. Clean toilet with mild non-abrasive cleaners without strong aromatics. Cleaners having high concentrations of aromatics such as pine-scented concentrated cleaners and strongly scented degreaser concentrates can cause the pump’s seal to swell and may contribute to a premature seal leak.
• The toilet has no wearing parts that need periodic replacement other than the shaft seal which, under normal conditions, should provide several years of service before needing replacement. The seal only requires replacement if signs of leakage are noticed under the seal housing positioned between the motor and toilet base assembly.
• Flood hazard. If the toilet is plumbed to an overboard discharge, close the discharge seacock before disassembling the toilet. Failure to do so can result in flooding which can cause loss of property and life.
• NOTICE : Before performing any service, turn off the electrical power to the toilet and rinse the water pump. Take precautions to ensure it is not turned on until the service is complete. Also, pump all water from the toilet bowl and if connected to an overboard discharge, close the discharge seacock.
• To replace the shaft seal, snap off the white motor cover and remove the pump assembly by removing the four screws with lock washers that secure it to the toilet base.
• Carefully slide the pump assembly from the base ensuring the macertor housing also slides out of the base with the pump. The pump chopper will engage the macerator housing and it may be necessary to gently tap the chopper against the macerator housing to free it from the base.
• Prevent the motor shaft from turning by inserting a screwdriver in the shaft slot at the rear of the motor and unscrewing the nut. Re-move the chopper blade and macerator housing from the motor shaft. Remove the O-ring from the O-ring groove around the outer diameter of the seal housing. With an allen wrench, loosen the centrifugal impeller set screw and slide the impeller off the shaft. Remove the two screws that secure the seal housing to the motor and slide the housing off the motor shaft. Remove the two seal washers from under the head of each of the two seal housing retainer screws. With a pair of needle nose pliers, grasp the shaft seal and pull it from the seal housing. Clean all parts and inspect for damage.
• Lubricate the OD of the new seal with a small amount of water and press it into the seal bore with the seal’s lip facing the threaded end of the shaft. Do not use the stainless steel star retaining washer supplied with the seal. Lubricate the ID of the seal and the motor shaft with a small amount of water-resistant grease. Ensure the slinger is properly positioned on the motor shaft next to the motor and slide the seal housing onto the motor shaft until it is against the motor end bell. Position a new plastic seal washer under the head of each of the flat head seal housing retainer screws and secure the seal housing to the motor. Slide the centrifugal impeller on the motor shaft positioning it about 1/32″ (1 mm) from the seal housing and secure it to the shaft with the set screw.
• Rotate the impeller to ensure it does not rub on the seal housing.
• Slide the macerator housing over the motor shaft, place the chopper plate on the end of the shaft and screw the locking nut onto the shaft. Tighten the nut while holding the motor shaft at the rear of the motor. Position a new O-ring in the seal housing O-ring groove (it may be retained in the groove with a small amount of grease). Slide the pump assembly into the toilet base ensuring the macerator housing is properly positioned within the base. The cut-out in the side of the macerator housing must align with the discharge port in the base (the macerator housing is keyed so it will only go in when properly positioned). Ensuring the O-ring is still properly positioned in the O-ring groove in the seal housing, place the pump assembly against the base and secure it in place with the four screws and lock washers. Replace the white motor cover by snapping it down over the pump motor.

Flood hazard. If toilet is installed below the waterline, it must be installed with a properly positioned vented loop in the discharge hose. Failure to do so can result in flooding which can cause loss of property and life.

SEAWATER PUMP SERVICE INSTRUCTIONS

• The SEAFLO rinse water supply pump needs no periodic maintenance for proper performance. The only time service work should need to be performed on the pump is if it should begin to leak water, suddenly delivers less water than normal or should stop pumping altogether. Should the pump begin to leak water, it will be necessary to replace the diaphragm. If the pump delivers a reduced rate of flow from normal or stops pumping altogether, it will be necessary to either remove debris from the pump’s flapper valves or replace the valve cage assembly.
• NOTICE: Before performing any service, turn off the electrical power to the toilet and rinse the water pump. Take precautions to ensure it is not turned on until service is complete. Close the inlet fitting seacock.
• It is generally easiest to remove the pump from its installed position so that the service can be performed on a workbench. To do this, disconnect the electrical wires from the motor wire leads. Push the port retainer clips back toward the pump motor and pull the port fittings from the port sockets. Unscrew the four pump mounting fasteners and remove the pump to a location where it can be disassembled without losing any of the pump components.
• Loosen the four 5/16″ hex (slotted) machine screws in the pump body and remove the body from the motor and wobble plate housing (use care to not drop and lose the port retainer clips and body retaining screws and washers). The valve cage will now be exposed which can be easily lifted off the diaphragm. Inspect the four outer inlet valves and central discharge valves to ensure they seat smoothly against the valve cage. Lift the outer edges of each valve to make certain there is no debris lodged under any valve.
• If there is debris lodged under any of the valves, it will cause a diminished flow rate or loss of flow entirely. If the valves do not seat smoothly against the valve cage, the valve cage assembly should be replaced.
• If the pump has been leaking, the diaphragm must be replaced. Remove the four phillips head diaphragm retainer screws and mushroom-shaped diaphragm retainer caps. Remove the diaphragm and diaphragm housing from the motor and wobble plate housing. Inspect the wobble plate bearing to make certain it is not corroded and still rotates smoothly.
• With the new diaphragm positioned in the diaphragm housing (ensure the raised sealing beads face outward away from the motor) hold it against the wobble plate with the four retaining cap holes aligned with the wobble plate sockets. Push each diaphragm retainer cap through the diaphragm and into the socket of the wobble plate. Secure each retaining cap to the wobble plate with a 1″ phillips head retainer screw. Place the motor on its rear end bell and position the valve cage against the diaphragm ensuring each cavities seal groove is seated on its sealing bead molded into the diaphragm. Ensure the O-ring seal that separates the pump’s intake chamber from the discharge chamber is properly seated in the ID of the raised lip around the central discharge valve.
• While holding the port retainer clips in their slide grooves in the pump body, po si tion the body on the diaphragm and inside the wobble plate housing. Secure the pump body to the wobble plate housing with the four 2-1/4″ machine screws and flat washers.
• Reinstall the pump to its mounting surface with four fasteners through the rubber grommets. Ensure the sealing O-ring is properly positioned on each port fitting and, with the retaining clips slid back, push each port fitting into its respective socket. Slide each port retainer clip forward until it snaps securely into its seated position. Reconnect the red motor lead to the positive supply wire and the black motor lead to the negative wire.
• Ensure the inlet seacock is open before re-storing power to and operating the toilet.
