■ Connection to the system
- Connect the unit to the water system by means of the fittings which are marked Flow and Return in fig. 3-5.
- All the water coils, including the optional extras, are equipped with air bleed-valves next to the upper union,and with water drain valves
need to the lower union.
- All the valves can be opened and closed with screwdrivers or Allen keys.
IMPORTANT!
!
- The water coils can be partially drained through the drain valves.
CAUTION!
- To drain them completely, they should be blown out with an air-jet.
■ When installation is complete, it is necessary to:
- Bleed the air contained in the circuit.
- Lag the connection pipes and any valves titted with anti-condensation material 10 mm thick or install the auxiliary drain.
- Pour water into the condensation collector tray and check that the liquid drains properly, following it right through to the exit of the
drainpipe. If it does not, check the fall and look for possible blockages.
■ Setting up the condensate drainage system
The condensation drainage system must be set up with an adequate fall, to ensure that the water escapes properly.
Following are directions for setting up a proper condensation drainage system.
■ Creation of the trap
The condensation drainage system must be fitted with a suitable trap to prevent seepage of odours. Following are directions for setting
up the trap (fig. 3-7).
■ How to turn the coil round, from fittings on the left standard) to fittings on the right.
The unit is supplied as standard with connections to the coil on the left. It is possible however to turn the coil round, so that the
connections are on the right.
The operation of turning the principal and supplementary coils round can be carried out with the unit in situ, but it is preferable to do it
before installation, with the unit on solid ground.
■ Procedure to reverse the coil
1. Remove the casing (on versions I);
2. Remove the screws on both sides, which hold the coil to the structure of the unit (fig. 3-8);
3. Turn the coil round in the opposite direction;
4. Re-fit the coil mounting screws;
5. Re-fit the casing (on versions I)
