3OPERATION
3.1Place of operation
1) The Thaya will work correctly when:
- The temperature range is from +16°C to +25 °C
- The ambient humidity max. to 60% RH
2) Do not place the Thaya Display Unit:
- Near a heating or cooling source
- Where sunlight can affect operation of unit
- Where it can be affected by a draugh from an air-conditioner or near the entry
- Near any other objects which could prevent proper ventilation
3.2Assembling
Before assembling consider where the unit will be placed. The Thaya allows the installation into a bench by
removing the front bottom panel.
To find out how to install the Thaya see “Installation into the table” at the end of this manual, page 13. If the information is
missing or the guide is unclear, contact your supplier.
1) The Thaya is to be placed onto a flat and level floor / surface. Ensure water tray can be accessed for filling and
removed for cleaning. Turn the adjustable feet to get level and stable.
2) Insert shelf brackets.
3) Insert grids to shelves.
4) If the model is provided with sliding back doors, insert them.
3.3Connection to power
The Thaya is designed for single-phase voltage 230V / 50 Hz. The power supply socket must be separately grounded
and protected by a fuse of 10Amp or 15Amp for 3 Tray. Other devices should not be attached to this separately fused
circuit. Ensure the electrical connections are protected and complies with applicable regulations.
3.4Before turning on for the first time
1) Visualy check that all packing materials and protective foil are removed.
2) Clean the inside space and shelves with a slightly damp cloth and a suitable detergent.
3) Dry the surface with a dry cloth.
4) The tray located at the rear portion of the bottom, (see chapter 2.3, position 4) should be loaded with approx. 3
liters of hot (50-60°C) water BEFORE you start. The water evaporates during operation and moistens the inner space
of case (mitigates drying on display).
Check the water level in the tank periodicaly to avoid its complete evaporation. The Thaya can NOT be used
WITHOUT WATER!
5) Heat the interior properly, see chapter 5.2 Turn on.

5OPERATION
5.1Control panel
5.2Turn on
1) Ensure water is in the water tray
2) Connect the power supply to the Thaya.
3) Turn on the main switch (3).
4) Set the required temperature by the thermostat button (1).
5) Turn on the light (2).
Let the empty unit run for at least one hour or until the desired temperature is reached. Food should be
inserted after the required temperature is reached.
After turning on the device, the elements will start heating and the fans will begin to circulate heated air through the
front exhaust vents up to the highest shelf. Heated air is then injected into all levels toward the rear doors. The air is
sucked through grids at sides of the unit and to the evaporator, where it is heated for further circulation.
The water from the tray evaporates during operation due to heat, and moistens the inner space of case
(mitigates drying on display). Check the water level in the tank periodicaly to avoid its complete evaporation.
The unit can NOT be used WITHOUT WATER!
5.3Setting
Temperature adjusting:
If the temperature is not suitable, adjust it with slow turn of the thermostat button (1) in the appropriate direction.

5.4Placing of goods in the cabinet
The Thaya is not designed for heating goods, but to maintain the temperature of pre-heated food during its presentation
in the unit. Food, where the temperature is lower or extremely higher than the temperature inside the display case,
should not be placed inside until at the same or similar temperature to the inside of the unit.
When placing goods on the shelf, ensure that:
- between pieces on shelves is a gap of at least 1 cm
- goods do not exceed the edges of shelves nor
containers
- total weight of the goods on one shelf does not
exceed the carrying capacity per shelf (10 kg)
Improper storage of goods slows the circulation of air
inside the display case and raises the temperature.
The front exhaust and side vents must not be covered by goods or other items!
Also, the space between the containers, shelves and the rear sliding door must remain free - goods shall not
exceed or overhang edges of the shelves nor containers!
When loading and unloading goods, open and close the door as quickly as possible to shorten the length of time that the
door is open, to prevent leakage of heated air (ie cooling the interior of unit).
5.5Turn off
1) Turn off the light (2).
2) Turn off the main switch (3).
3) Disconnect the unit from power supply.
4) Remove all the goods and wait until is cooled, then clean the cabinet, see 6.1 Daily maintenance.
5) To prevent mould and unwanted odors, leave the door open to dry up the inside space completely.
Always beware of touching heated internal parts of the unit without proper tools, ie hands protection.
