4.5 Condensate Discharge
When mounting the condensation discharge device,
connect to the condensate collection tray discharge
union (Fig. 19 Ref. C) a pipe for the outflow of the liquid
(Fig. 19 Ref. B) blocking it inadequately. The condensate
discharge network must be suitably sized (minimum
inside pipe diameter 5/8").
If the condensation needs to be discharged into a
container, it must be open to the atmosphere and
the tube must not be immerged in water to avoid
problems of adhesiveness and counter-pressure
that would interfere with the normal outflow.
4.6 Evacuating air while filling the system
If there is no electric power and the thermo-valve has
already been powered use the special cap to press the
valve stopper to open it.
Start filling by slowly opening the water system filling tap.
Use a screwdriver to unscrew the side air vent valve (Fig.
20 Ref. A). When water starts coming out of the air vent
of the appliance, close them and continue filling until each
reaching the nominal value for the system.
Check the hydraulic seal of the gaskets.
It is advisable to repeat these operations after the appliance
has been running for a few hours and periodically check
the pressure of the system.
