The inside of the Sanipack 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 Sanipack 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, picking up the impeller pump mounted beneath the motor.
The unit pumps the effluent upward to 15 feet or 150 feet horizontally (with gravity fall). Once the water is discharged and 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 Sanipack takes about 7-9 seconds depending upon the discharge pipe run configuration; power consumption is therefore minimal.
In addition to the toilet waste, the Sanipack will also discharge gray water from various other sanitary fixtures such as a sink, a shower, and a urinal. When adding a 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 Sanipack via two 1-1/2 inch inlets on either housing side. Either one or both inlets can be used as required. The discharge elbow on top of the Sanipack can be turned left, right, or towards the back, depending on the installation. 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 lid. 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.
The Sanipack is designed to be used with a wall-hung toilet. The depth of the case allows for this pump to be installed within the wall. Since the reservoir, the macerating pump, and the pipes are hidden from view, this type of installation gives you the lean and clean look of a European bathroom.
