WARNING
4.3.1 WSH Installation Modes
To proceed with the installation of the machine, implement the following procedure:
Lift the two units of the machine with a suitable lifting means, using the appropriate hooks.
1.
Fasten the condensing part to the vertical wall with n°4 screws, as indicated in Figure 1, maintaining a minimum height
2.
above ground of 400 mm.
3. Proceed to fasten the evaporator inside the cold-room with 4 steel nuts (Figure 1).
4. Extend the drain pipe of the water tank located below the evaporator with a rubber pipe (minimum resistance temperature:
90 °C ) up to the outside of the cold-room, making a syphon (Figure 1).
5. Make a hole in the wall of the cold-room for the air delivery, suction, and water drain pipes to pass, and for the pipe
connected to the water supply network.
Make a hole for the electrical cables to pass: the power supply cable, the cable of the evaporator fans, the cable of the
6.
resistances, and the solenoid valve cable.
Installation of the Evaporator
Please see Figure 1 and the technical specifications reported in Chapter 9 – Attachments.
Refrigerant Connection
To perform this connection, arrange for the piping of the liquid and suction line, in accordance to the diameters of the
attachments present on the machine. The attachments are positioned on the sides of the two units (Figure 2).
The suggested diameters are valid for the maximum lengths of up to 10 meters. For greater lengths, size the diameters in such a
way that the correct speed of the gas is ensured.
The piping must be fastened to the wall in proximity of the curves, the welding, or every 1.5-2 meters in the straight segments.
:
the probes must be positioned at a certain distance from doors and/or windows possibly present, so
that a correct reading of the temperature and humidity actually present in the environment can be
made.
