Product Information

The product is a macerator designed for use with a toilet using a horizontal outlet. It is suitable for indoor use only. The unit must be installed to comply with current UK electrical regulations and must be earthed. The electrical installation should be done by a qualified person. The unit requires a fused spur rated at 3 amps and uses a cable type of H05VV-F, 3G0.75mm2 VDE. The IP rating of the appliance is IP54.

The unit is designed for a horizontal toilet outlet with the standard European 18cm to the outlet centre from the floor. All other inlets must be gravity fed into the unit. The outlet comes as standard with a 32mm connection, but a 22mm reducer can be used if needed. Smooth curves should be used for any bends in the connecting pipe work to avoid blockages.

The macerator can be used with multiple inputs or just one. Blanking plates are provided to help with installation. A check valve must be fitted as closely to the macerator as possible, and a distance of more than 30cm should be avoided. The valve should be sealed with jubilee clips, and the arrow on the valve should point away from the macerator.
