ENGLISH
- 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%.
7.5.2. Electrical connection
In the recovery unit Termo-Reg range, all components integrated into the device, are supplied
into the electrical panel (motors, pressure fi lters, motor pressure switches, temperature sen-
sors, batteries and by-pass damper).
The electrical connection is limited to the connection of control terminal (10 m. of supplied ca-
ble) and possible electrical accessories as such as CO
2
sensors or control valves for water coils,
and fi nally the connection of the power supply line.
Make electrical connection in accordance with the described in the corresponding wiring dia-
gram, found in this manual.
7.5.2.1. Connection of the external remote control
Inside the control cabinet remote console and a cable with terminal pin RJ-11 is supplied at the
ends. Supplied cable length 10 m.
