7.5.1.1. Connection with air duct

The fans are always blowing out with regard to the machine. Before making the connection of air
lines, verify existing identifi cation labels in each mouth of the heat recovery units.
7.5.1.2. Connecting the water coil piping. DC Versions
Connecting the unit to the water network
- Maximum pressure: 31.62 bar
- Maximum temperature: 150°C
• Water coils of DC versions have threaded connections. Secure the coil manifold with the ap-
propiate tool when tightening the threads. This will prevent the force from being transmitted
to the manifold, which can damage it.
• The following table indicate the size and type o thread used on water coils for DC versions:

• To ensure the installation on a hand, it is essential that the installation includes the following
elements:
- Unit intake pre-fi lter that traps suspended particulate matter.
- Bleed valves should be fi tted at each of the high points in the installation.
- Auto-fi lter valve to keep water in the hydraulic system at all times.
- Pressure to detect the lack of water pressure.
- Shut-off valves must be installed at each connection on the water line to allow the unit to be
isolated if necessary (to clean fi lters, make repairs, replace parts, etc) and avoid the need to
completely drain the water circuit.
- Anti-vibration bellows should be installed at the inlet and outlet from the unit to prevent
