Sanimulti Macerator Pump

1. Safety

❗ DISCONNECT ELECTRICAL POWER BEFORE WORKING ON THE PUMP!

Plumbers/Contractors, please ensure a copy of the installation instructions is left with the end user for future reference.

2. Recommended Use

The Sanimulti is a compact, versatile macerator pump designed for light to medium commercial use. The unit is designed to receive and pump away wastewater from a WC, bath, shower, and basin.

Notice:

• DO NOT dispose of solvents, paints, turps, caustic acid, or other corrosive acids or cleaners.
• DO NOT dispose of hot water in excess of 60°C.
• DO NOT use cleaning products that produce excessive foam, as this may cause motor damage.
• DO NOT install in a hairdressing salon without the use of a hair trap first.
• DO NOT dispose of paper hand towels, sanitary napkins, or wet wipes.
• DO NOT dispose of foreign objects or use excessive amounts of toilet paper.

3. Description

3.1 Technical Data

3.2 Flow Characteristics

A graph shows the relationship between discharge height (in meters) and output (in litres/min). The curve indicates that as the discharge height increases, the output decreases.

3.3 Pumping Distance Performance

NOTE: A minimum 1% fall is required on the horizontal run. The pipe size must be increased by one size minimum after the first 5 meters of horizontal run.

Diagrams illustrate maximum horizontal pumping distances for various vertical pumping heights, ranging from 1 meter up to 7 meters.

3.4 Dimensions

Diagrams show the physical dimensions of the Sanimulti unit, including width, height, and depth, with specific measurements provided.

4. Installation

• The macerator pump should be installed to allow full access for servicing or removal. If the unit is concealed in a wall cavity, a 500mm access panel must be provided.
• The unit must be located on the same floor as the fittings it serves.
• All incoming pipework must have a constant gradient of 1:40.
• The unit has 2 lower lateral inlet ports. If an inlet is not in use, cap it off with the provided side plug.
• The top of the unit features a dedicated vent point with an integrated carbon filter to neutralize odors. This point can also be used as an optional external vent connection to the atmosphere.
• Where possible, venting should comply with current plumbing venting requirements, such as AS 3500.
• Before commissioning, ensure all connections are secure and watertight.
• Electrical installation must be carried out by a registered electrician in accordance with AS/NZS 3000.
• AAV (Air Admittance Valve) valves are not an alternative to venting to atmosphere, as the unit requires two-way venting for correct activation function.

4.1 Connecting P Trap, Wall Face or Wall-Mounted Pan Installation

The pump is supplied with the toilet connection prepared for side entry (Fig 1). Use the supplied pan connector for standard P-trap toilet suites or to connect to a 100 mm DWV pipe for remote installation (e.g., wall-hung pans). If direct connection to a toilet pan is required, the configuration can be changed (Fig 2).

Fig 2: Shows the unit with an inlet for a toilet, numbered 1, 2, 3.

4.2 Important Removing Accessories

NOTE: Check to see that all accessory parts are taken out of the pump unit!

The document lists the "Small lifting unit with complete comminutor" which includes the collecting tank, pump, comminutor, and connecting cable. It also lists "Accessories" including sealing sleeves, hose clips, union nuts, pressure sockets, elbows, safety nuts with check valves, sleeves, nipples, seals, multi-hose connections, buoyancy controls, extraction tools, and stickers.

4.3 Relocating Pan Inlet Connector

Detailed step-by-step instructions are provided with diagrams for relocating the lateral inlet. This involves removing covers, unscrewing inlets, greasing O-rings and threads, and reassembling components using a special tool and supplied grease.

Diagrams illustrate the process of removing covers, unscrewing inlets, applying grease to O-rings and threads, and reassembling the inlet connector.

4.4 Pump Line Connection

The pressure line exits from the top of the device. It can be connected straight or using a 90° elbow. The pressure line must have a minimum internal diameter of 20 mm. A PVC pressure ball valve must be installed on the pump line for isolation during servicing.

4.4.1 Connection option using a multi hose connection:

Diagrams show the pressure line connected straight and with a 90° elbow, noting that a PVC pressure ball valve must be installed on the pump line.

4.4.2 Connection option with double threaded nipple 1 1/4":

Step-by-step instructions and diagrams show how to remove the plastic thread from the safety nut, insert a double threaded nipple, and connect the pressure line using a union nut.

4.5 Venting

The pump features an integrated active carbon filter with an anti-flood valve to neutralize odors. Venting should comply with current plumbing requirements (e.g., AS 3500). The initial position of the venting with activated carbon is shown.

Diagram shows the initial position of the venting system with numbered inlets (1, 2, 3).

Changing the Venting Position:

Detailed step-by-step instructions with diagrams explain how to change the venting position by removing and repositioning inlet covers and valve inserts, and transferring the activated carbon filter.

Diagrams illustrate the process of removing covers, manipulating valve inserts, and transferring the activated carbon filter.

4.6 Additional Connections

4.6.1 Upper Connections

Step-by-step instructions and diagrams detail how to modify the upper inlet for additional connections.

Diagrams show the process of removing and modifying the upper inlet.

4.6.2 Lateral Inlets

Instructions and diagrams are provided for connecting a shower to the lateral inlets. This includes attaching a sealing sleeve and hose clip, and cutting the sleeve to the correct length.

Diagrams show the process of connecting a shower to the lateral inlets, including attaching a sealing sleeve and hose clip.

4.7 Fixing

The pump can be securely fixed to the floor using the supplied fixation brackets and screws.

Diagram shows the pump with fixation brackets and screws.

4.8 Connecting a Shower

When connecting a shower to the Sanimulti, the shower must be elevated to a height of at least 170 mm from the shower grate to the base of the pump on the finished floor level. A 1:40 or 3% gradient must be maintained on the shower waste fixture line.

Diagram illustrates the required minimum height and gradient for connecting a shower.

4.9 High Level Control Sanialarm Interlock Connection (Optional)

The Sanialarm Interlock connects via a "Quick plug float switch" socket. One end of the accessory lead plugs into this socket, and the other end connects to the pump. Follow the instructions supplied with the alarm for final connection.

Fig 1: Shows the Sanialarm unit with the "Quick plug float switch" socket.

Fig 2: Shows the connection point on the pump.

5. Trouble Shooting Guide

For repair and maintenance works on the pump, always disconnect the power plug from the power socket.
