•A suitable safety switch / Residual current device must be installed near the
appliance between the power supply and the appliance. The manufacturer will not
be held liable for damage originated by failure to observe this requirement.
•If any faults are observed during the installation, the supplier should be notified
immediately.
When a number of appliances are installed in line, they should all be ground bonded at the point
provided for that purpose.
To access the connection strip when a permanent connection needs to be made, release the cover of
the machine’s front (see chapter 2. General measurements and connections). The power cable is
connected to the connection strip. It is also possible to change the machine configuration here.
The manufacturer will not be held liable for any personal or material damage to the
machine resulting from incorrect installation or failure to comply with the
manufacturer’s specifications.
It is the personal responsibility and obligation of the customer to contact a
qualified electrician to assure that the electrical installation is adequate.
8.4 Hydraulic connection
The new hoses supplied with the appliance should be used (do not reuse old hoses).
Before connecting the machine to the water supply, the water quality should be tested.
Recommended water quality:
pH:
6.5 to 7.5
Alkalinity:
Less than 50 ppm (mg/L)
Free Chlorine:
Less than 0.2 ppm (mg/L)
Total Dissolved Solids (TDS):
Less than 60 ppm
Chlorides:
Less than 30 ppm (mg/L)
Sulfates:
Less than 40 ppm
Hardness:
Less than 3 gpg (52 ppm)
Iron:
Less than 0.1 ppm
Conductivity:
400 –1.000 µS/cm
Copper:
Less than 0.05 ppm
Silica:
Less than 12 ppm (mg/L)
Manganese:
Less than 0.05 ppm
Water installation is carried out as shown in Fig. 1:

Use 3/4” copper tubing inlet line.
It is necessary to remove all foreign debris from the water line that may potentially get trapped in the
valves or cause an obstruction, prior to connecting to the machine.
Use only the supplied hoses (3/4” Female hose connector) at the water connections. Failure to do so
may result in damage to the solenoid valve threads and leaking. Tighten by hand. Connect the bent
side of the hose to the machine. Adaptor supplied for ¾” female garden hose connection.
FOR HARD WATER SUPPLIES WITH A HARDNESS OF OVER 3 gpg OR 5ºfH AND PH BEYOND
THE RANGE OF 6.5 –7.5, A WATER CONDITIONER/DESCALER MUST BE INSTALLED.
In addition to water quality, the pressure of the mains water supply must be considered. This is
important to ensure the machine operates correctly.
CO models: Required water dynamic pressure measured at pressure gauge 25psi ± 5psi.
COP models: Required water dynamic pressure measured at water inlet between 20-58 psi.
CAUTION:Do not confuse static pressure with flow pressure. Static pressure is the line pressure in
a “no flow” condition (all valves and services are closed). Flow pressure is the pressure
in the fill line when the solenoid valve is opened during the filling or cycle.
In areas where the pressure fluctuates or it is higher than the recommended pressure, a water pressure
regulator shall be installed between the shut-off cock and the water hose (Fig. 1.).
If the water pressure is less than required, installation of a water pump is required.
The hot water heater should be set to deliver 140 F (not lower than 122 °F) water temperature to the
dishwasher for best results, except in hood type HRS models, where the water inlet temperature
should be between 41 ºF and 77 ºF in order for the HRS system to function properly.
Slowly turn on the water supply to the machine after the incoming fill line and the drain line have been
installed. Check for any leaks and repair as required. All leaks must be repaired prior to placing the
machine in operation.
The following requirements are necessary for the correct hydraulic installation of the machine.
•The hydraulic circuit must be fitted with a valve to shut-off the water supply.
•Check that the mains pressure is within the range indicated.
•To optimise the work of the machine, the water temperature at the machine intake should be
within the following range: 122 ºF (50 ⁰C) < Hot water Temp < 140 ºF (60 ⁰C)
For HRS hood type models: 41 ºF (5 ⁰C) < Water Temp (HRS) < 77 ºF (25 ⁰C).
•If using hot water, the water temperature must not exceed 60 ºC / 140 ºF.
•All the machines should have a 3/4” screw-on connection.
8.5 Drainage connection
Attach the drain hose as shown in Fig. 2. The drainage pipe must always be fitted on a siphon to
prevent the return of odours.
All piping from the machine to the drain must be a minimum 1-1/2” I.P.S. There should also be an air
gap between the machine drain line and the drain. For natural overflow efficiency use floor drain.
The water draining from the machine must flow freely and therefore the drainage pipe should be lower
than the drainage outlet (Fig. 2).
If the drainage pipe is not lower, a drainage pump will be required. This must not be mounted at a
height of more than 23 5/8”for hood type dishwashers or 19 3/4” for undercounter dishwashers and
glasswashers (Fig. 3). In this case, the pump may be requested at the time of purchase or
subsequently.

The drainage pump must only be installed by personnel authorised by the
manufacturer, and the manufacturer does not accept liability in the event of
incorrect installation.
8.6 Hydraulic rinse aid dispenser (CO MODELS)
Installation: Take the tube located in the back or your machine marked “Rinse Aid” and place inside
rinse container.
Tubes are transparent to provide you visible mean that chemicals are being dispensed.
Operation: This dispenser absorbs the rinse aid when it detects a loss in pressure during rinsing. That
is, when the filling solenoid valve closes, a vacuum is created that makes the rinse aid dispenser
absorb the fluid to which it is connected.
Adjustment: The dispenser should be adjusted when the machine is installed to ensure that the wash
is optimised from the start. The setting should be adjusted according to the type of rinse aid and the
water hardness.
WATER PRESSURE MUST BE MINIMUM 20 PSI AT THE PRESSURE GAUGE FOR THE RINSE
AID DISPENSER TO OPERATE PROPERLY.
