Important Notes
● Use in Accordance with Regulations
This machine is exclusively to be used to wash ware such as plates,
cups, glasses, cutlery, trays etc.
Do not use for electrically heated cooking and warming appliances.

1.5 Attach dish rack tables and accessories
– See separate instructions.
– Seal screw holes.
– Allow a slight inclination to the machine (if needed, adjust by
turning the feet).
– Ensure that the rack track level of the machine is the same as
the level of the table or roller conveyor. (This means that the
"dogs" on the rack transportation must extend above the table
by more than 12 mm.)
–Table end switch:
Wiring to control box must be protected.
–Tables on rollers including end switch:
Close the connector of the cable and lock it.

2 Electrical connection
Must be carried out by a qualified technician according
to the national and local codes.
2.1 Check
– Remove the lower front panel (with screw driver) and take out
the wiring diagram.
– The electrical supply shall comply with the name-plate data and
the wiring diagram.
– Line fuses and cable cross section shall comply with the
requirements.
– Supply disconnecting device (main switch with emergency stop
function) adjacent to the machine (if not built in).
2.2 Connection
– Draw cable (H07RN-F) through cable gland in the side panel
at the exit end of the machine.
– Connect wires to main terminals or to main switch (if built in).
– Tighten all terminal screws (may be loosened during transport).
– Tighten the cable gland.
According to EN 60 335 the appliance must be connected to
an equipotential conductor. The connecting screw "A" ( )
is located beside the cable inlet.
3Water connection
Must be carried out by a qualified plumber according to
the national and local codes.
The machine must be operated with water of drinking quality.
For water with an extremely high mineral content, water
treatment is recommended.
3.1 General
– Connect water supply and drain pipes according to installation
plan.
OK
0
– A non return valve ED type is fitted to machine as standard.
6
3.2 Fresh water supply for rinse (G 3/4")
– Should be soft (up to 8° Clark, resp. 1.1 mmol/l).
–Must be cold if condenser is fitted.
– Line flow pressure 1.5 - 6 bar at ~ 500 l/hr.
– Provide shut-off valve and line strainer at site.
3.3 Fresh water supply for fill (G 3/4" – Option)
– Should be soft (up to 8° Clark, resp. 1.1 mmol/l) and
warm (50 - 60°C).
– Line flow pressure 1.5 - 6 bar.
– Provide shut-off valve and line strainer at site.
3.4 Drain connection
To be connected to site drain:
– Tank drains DN 50 (HT Pipe)
– Drip water drains of tabling, sink and other elements.
– All drains must be connected to goose neck
(individually or single point).
4 Exhaust connection
– Connection must be carried out in conjunction with competent
ventilation engineer.
– Please pay attention to notes on the service drawing.
4.1 Exhaust into the kitchen
(only possible in connection with sufficient room ventilation)
– Avoid condensate damage by mixing exhausts from vent outlet
of the machine, directly with room air (air distributor).
4.2 Exhaust pipework
– Leave a distance (approx. 10 cm) between machine exhaust
and site channel.
– Use additional ventilation fan, as the built-in ventilator has no
compression.
The volume of air to be evacuated from site has to be larger
than the volume of air of the machine (see installation plan).
– To prevent corrosion damage, provide exhaust channel in
stainless steel or synthetic material.
– In case of extremely low temperatures:
provide insulation and self closing anti-freeze shutter.
7
5 Dispensers
of detergent and rinse agent
– Normally, dispensers and controls are delivered and installed
by the detergent and rinse agent suppliers.
– Install dispensers, controls and containers in a way that they are
easy to handle and do not disturb machine operation.
– Rinse agent connection is provided after the rinse booster
heater.
– Te r minals are provided behind the lower front panel
(see wiring diagram).
It is recommended that dispensers and their controls are
not fitted directly onto machines!
(Thermal insulation panels could be damaged.)
Use only commercial detergent and rinse agent (suitable for
professional and industrial operations).
Please pay attention to the manufacturers safety regulations
and instructions.

Gastronorm pans and other large containers or boards should
ideally be washed in a separate Utensil Washer.
In rack conveyor machines these items may cause problems
such as splash-over leading to low water levels in the tank/s
and poor rinsing.
On the occasions when these items are to be washed, they
should be loaded sloping towards the direction of machine
operation as shown in the picture. This will reduce the
problems described above.
