Electrical Connection - Whirlpool SDD 534 U Manuel D'instructions

Make sure the pressure of the mains water is between the values written on the table.
If it is lower than 200 kPa (dynamic pressure), to ensure the perfect operation of the machine, it is mandatory to
install a pressure booster pump (on request, the machine can be supplied with a built-in pressure booster pump).
If the mains pressure is higher than 400 kPa, you need to install a pressure reducer.
For water with average water hardness above 12°f, it is mandatory to use a scale inhibitor. On request, the
machine can be supplied with a built-in scale inhibitor.
If the machine is equipped with a scale inhibitor, you need to regularly regenerate the resins using special
regeneration salt.
The salt compartment can take approximately 1 kg of grain salt.
The salt compartment is located on the bottom of the tank. Take the basket out, unscrew the cap and pour salt in
using the funnel supplied with the machine. Before screwing the cap back on, remove any spilled salt near the
opening. Top-up with salt when there is no water in the tank so that the washing water cannot get into the water
softener. Always unplug the machine from the mains power supply before doing this operation. Remember to plug
the appliance back into the mains socket after finishing the job.
The first time you use the appliance, after adding the salt, add some water to the salt container.
NB: For water with hardness above 12°f, if there is no scale inhibitor, the damages caused by scale will not be
covered by the warranty.
The temperature of the supply water must be between the values indicated on the table.
Each machine is supplied with a water filling hose with threaded 3/4"fitting.
The drainage hose is to be connected, after adding a siphon, directly to the drains. The water falls freely into the
drains, therefore the point where it is connected to the drain outlet must always be below the level of the wash tank.
If the existent drain point is above this level, a suitable drain pump has to be installed (optional). Do not fit the drain
hose into the drains of sinks, bathtubs etc.
For versions with built-in osmosis system, install the carbon or mesh filter supplied on the water supply cock. The
water hardness must be between 7 and 12°F and the maximum temperature 30°C.
The filters must be replaced at least twice a year.
Failed observance of these parameters will cause the internal osmotic membrane to deteriorate rapidly.
Make sure the water hardness is between 7 and 12°F, otherwise install a water softener to prevent damages
caused by scale, which are not covered by warranty.

2.4 ELECTRICAL CONNECTION

The electrical connection must be carried out according to technical standards currently in force.
Make sure the measured mains voltage matches that written on the technical data nameplate of the dishwasher.
You have to fit an appropriate omnipolar protection circuit breaker switch suitable for the input of the dishwasher.
This switch must be used exclusively for this utility and installed right next to it.
Make sure the electrical systems are suitably earthed.
The machine also has a connection, at the rear bottom part, marked with the equipotential symbol
to connect various appliances together equipotentially (check standards on electrical systems).
FOR MACHINES WITH THREE-PHASE POWER SUPPLY, BE CAREFUL NOT TO INVERT THE PHASE WIRES
WITH THE NEUTRAL WIRE.
ATTENTION ! MAKE SURE THE THREE-PHASE PUMPS TURN IN THE CORRECT DIRECTION (where
installed).
IF THE POWER SUPPLY CABLE SHOULD GET DAMAGED, IT MUST BE REPLACED EXCLUSIVELY WITH A
NEW ONE FROM THE MANUFACTURER OR FROM AN AUTHORISED SERVICE CENTRE AND BY
QUALIFIED TECHNICIANS.
2.5 TEMPERATURES
The thermostats are preset at the following temperatures: 55°C for the washing water (tank) and at 82°C for the
rinse water (boiler). The tank thermostat cannot be adjusted whereas the boiler thermostat can; turn the knob on
the thermostat, or use the controls on the control panel for versions with electronic control panel.
3 - RINSE AID AND DETERGENT DISPENSING
Only use detergents and rinse aids specific for industrial dishwashers. Do not use normal washing up liquid. Do not
use detergents for domestic dishwashers.
Ask a specialist in chemical products for the correct choice of products to use and their quantities.
