- suck up the powder with a vacuum cleaner

- wash the filter with running water without using detergents or solvents, and leave to dry.

It is forbidden to use the unit without the net filters.

The appliance is fitted with a safety switch that

7.5

Maintenance must be carried out by a qualified installer or by a specialised service centre.

Effect Cause Solution

Ventilation takes a long time to start when new temperature settings or anew mode is activated.

The device doesn't start ventilating. No hot or cold water in the system.

Ventilation does not start even if there is hot or cold water in the hydraulic circuit.

The device leaks water when heating.

Rust is forming on the front panel. Thermal isolators detached.

Water droplets are forming on the grill and the air outlet.

The device leaks water only when cooling.

The device makes excessive noise.

Troubleshooting

disconnect mains power immediately and close all water taps.

occur, contact an authorised service centre or qualified personnel, do not try to repair yourself.

Troubleshooting table

The circuit valve needs time to open and to let cold or hot water circulate.

The hydraulic valve stays closed.

The fan motor is blocked or burned out.

The microswitch that stops ventilation when opening the filter grill doesn't close properly.

Electrical connections are incorrect. Check the electrical connections. Water leakage from the system

plumbing. Leaks from the valve group. Check the seals.

In high relative ambient humidity (>60%), condensation may occur, especially when the fan is at its minimum speed.

The condensation tank is blocked.

The condensation drain does not have sufficient incline to drain.

The connection pipes and valve group are not well isolated.

The fan is touching the structure.

The fan is unbalanced.

Check for dirt in filters and if necessary, clean them.

- Ventilation does not start even if there is hot or cold water in the hydraulic circuit.

- The device leaks water when heating.

- The device leaks water only when cooling.

- The device makes excessive noise.

- Rust is forming on the front panel.

Wait 2 or 3 minutes for the circuit valve to open.

Check that the boiler or the water cooler are working.

Disassemble the valve body and check and restore water circulation.

Check that the valve is working by powering it up separately from a 230V supply. If it starts working, the problem may be with the electronic controller.

Check the motor windings and that the fan can turn freely.

Check that closing the grill closes the contact on the microswitch.

Check for leaks and tighten all connections.

Check that the thermal sound isolators are positioned correctly, paying particular attention to the one positioned at the front above the winged battery.

As soon as relative humidity decreases, the problem will disappear. In any case, should some water droplets fall inside the units, it does not mean that there is a malfunction.

Slowly pour a bottle of water in the lower part of the battery to check drainage; if required, clean the tank and/or improve the incline of the drain tube.

Check pipe insulation.

Check for dirt in filters and if necessary, clean them.

An unbalanced fan causes excessive vibrations in the machine: replace the fan.

Clean the filters.
