EN - PAD / PAD1 DEMINERALISED WATER PUMP
WARNING
This instruction sheet is intended for authorised SMEG technical
personnel.
1 CONTENTS OF THE PACK
1. 1 (one) pump support box; the steel box contains the assembled PAD pump.
2. 1 (one) power cord for electrical connection of the pump.
3. Mounting and sealing accessories (4 self-tapping screws for sheet metal, for fixing the box to the
rear casing, one gasket for connecting the water supply hose to the pump)
2 ATTENTION
SMEG appliances may not be connected to non-pressurised demineralised water supplies (e.g. tanks
operating by gravity) unless a special "PAD" demineralised water pump is installed.
This pump ensures that the demineralised water is supplied to the appliance with sufficient pressure to
ensure its proper operation. The PAD is installed on the outside of the rear of the appliance.
The PAD must be installed on the appliance by a SMEG authorised technician.
WARNING - WHEN INSTALLING THE "PAD" OR "PAD1" MAKE SURE THAT:
The pump intake pressure is less than 1 bar. SMEG is not liable for any damage if the
demineralised water pump is installed with higher intake pressures.
Warning: this component is powered at mains voltage:
~230V 50Hz 1/N/PE - grounding is required.
SMEG declines all responsibility for any damage or injury caused by incorrect installation
of the pump by unauthorised technical staff. Use only the fixing devices supplied by Smeg.
WARNING – DEMI WATER SOLENOID VALVE FLOW REDUCER
In some cases, if the water pressure is insufficient for proper operation of the solenoid
valve even with the pump installed, the flow reducer fitted inside the valve must be
removed as shown below.
1. Remove the valve's external filter (white)
