Condensate Drainage - S&P CADB/T-N PRO-REG Instrucciones De Uso

• Water coils of DC versions have threaded connec-
tions. Secure the coil manifold with the appropiate
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
the transmission of vibrations that could result in damage to the heat exchanger coil due to
excess stress on the circuits.
Once the installation is performed check that the heating water fl ow is adequate.

7.5.1.3. Condensate drainage

The units are supplied with 2 drains (one for each circuit). For added security it has to connect
two drains to the condensate discharge pipe. This connection must be made through a pipe of
22 mm of inner diameter and a fl ange for secure fi xation.
Drainage system
• To ensure the removal of draining condensate from the tray a siphon must be installed with
pressure head difference in mmWG greater than the
pressure provided by the fan.
• The horizontal sections should have a minimum slope
of 2%.
