the country where it is installed is recommended. In any case, always use appropriate
equipment and clothing, such as: safety shoes, protective gloves, a level.
For installation, please proceed as follows:
carefully inspect the installation area, removing any danger(s) to the operator:
Do not position the cabinet:
in environments with the presence of explosive gaseous substances;
outdoors and therefore where there are atmospheric agents;
near heat sources (in direct sunlight, near heating systems, incandescent lights,
etc.)
near air currents (near doors, windows, air-conditioning/heating systems, etc.)
exceeding speeds of 0.2 m/sec.
Remove the wooden supports on the bottom (used for transportation) and attach the
adjustable feet (Rif. 2) positioning them so that the unit is horizontal, using a level (Rif.
1) to check the alignment.
Before connecting the unit to the electricity, ensure that the plate data corresponds to
the characteristics of the electrical system to which it is to be connected.
For the unit to function properly, the temperature and relative humidity must not
exceed the limits for climate class 3 (+25°C; R.H. 60%) as established in EN-ISO
23953 - 2 regulations, under which the unit was tested
If the unit is moved, repeat the levelling process, as improper levelling
could compromise the unit's operations.
Specifically, the Wels-WelsR290 requires continuous and adequate air
circulation through the condensation unit in order to guarantee conformance
with the risk evaluation level. In addition, any obstacle able to reduce air flow
could have negative effects on the safety of the cabinet. Due to the explosive
nature of the refrigerant, an environment with a minimum volume of 25 m
natural air exchange is required for each Wels-WelsR290 cabinet.

BEFORE STARTING ANY OPERATION, FIRST DISCONNECT THE SYSTEM FROM
THE POWER SUPPLY!
The systems must be completed in accordance with the regulations that
govern construction, installation, use, and maintenance as envisaged under
the norms in effect in the country where the unit is installed.
ARNEG Spa declines any responsibility with regards to the user and third-
parties for damages caused by breakdowns or malfunctioning of the systems
installed upstream to the unit and for damages caused by the same due to
causes directly attributable to malfunctioning of the electrical system.
The unit must be protected upstream by an automatic omnipolar
thermomagnetic switch with appropriate characteristics. This must also act as
a general line disconnection switch.
The unit comes with a connection ready for a plug (NOT SUPPLIED). Attach a
plug of suitable capacity for the electrical connection, onto the power lead in
compliance with safety rules: yellow-green = earth sky blue = neutral brown
=live and conform to the national regulations in effect
Establishment of the electrical power supply line to the point of where it connects to the
unit is the responsibility of the Client. The dimensions of the electrical energy power
supply line must be determined in accordance with the electrical power used by the
unit (see Technical Specifications).
Remove any metal objects worn: rings, watches, bracelets, earrings, etc.
Check the electrical diagrams before carrying out the connection
Check that the voltage supply is as specified on the plate data.
For power lines exceeding 4-5 metres in length, increase the cable section
accordingly.
