The inside of the unit is comprised of a pressure chamber, which starts and stops the unit, and the motor, which drives the stainless steel macerator blades and the pump. When the flush is activated, the water flowing into the Saniaccess 3 activates a micro switch in the pressure chamber, which starts the motor. The motor is sealed for life in an oil-filled enclosure. A standard spindle/shaft drives the impeller and the macerator blades. The moving parts, therefore, are kept to an absolute minimum. Water and organic waste matter enter the chamber and are reduced to slurry as the macerator blades rotate at 3600 RPM.
The centrifugal force causes the reduced solids to be ejected through a grill into the container, where it is picked up by the impeller pump mounted beneath the motor. The unit pumps the effluent upward to 15 feet and 150 feet horizontally (with gravity fall). Once the water level in the container goes down, the micro switch deactivates the unit until the flush is activated again. A standard operating cycle for Saniaccess 3 takes about 10 - 12 seconds depending upon the discharge pipe run configuration; power consumption is therefore minimal.
In addition to the toilet waste, the Saniaccess 3 will also discharge gray water from various sanitary fixtures such as a sink, a bathtub, a shower, and a urinal. When adding a bathtub or shower, a base will have to be constructed. This base should be made out of a 2" x 6" (minimum) or 2" x 8" (recommended) on edge to allow for the installation of a P-trap and the required 1/4" per foot gravity flow towards the pump unit.
The wastewater from other sanitary fixtures is discharged into the Saniaccess3 via two 2-inch inlets on either housing side. Either one or both inlets can be used as required. Depending on the discharge installation, the discharge elbow on top of the unit can be turned left, right, or towards the back. A non-return valve, which comes already assembled on the discharge elbow, prevents backflow into the unit.
This unit has been designed with a vent connection on the top of the unit. All plumbing codes require connection to a vent system. Please note that the vent system should be a two-way air vent. Mechanical vents, air admittance valves, or similar devices are not permitted as these are considered one-way air vent systems. It is also highly recommended that the macerator/pump be connected to a Ground Fault Interrupter (GFI) circuit.
Periodic maintenance can be accomplished quickly without disconnecting the unit from either the toilet or the rest of the plumbing system. Through one service panel, a service contractor can access the electrical components and the level sensor mechanism of the pump. The second service panel provides ready access to the basket area around the macerating blades to easily remove any large objects that may have been accidentally flushed.
The Saniaccess 3 unit must be connected to our rear discharge toilet. This system uses much less water than a regular toilet. Note: This toilet only works in combination with Saniflo systems.
