Salda VEGA 350 E Installation And Maintenance Manual page 39

• Power and control panel cables are transferred through the collars in front of the unit (see. Components).
• Units have rotating parts and are connected to the power supply. This could be dangerous to human health and life. Therefore, during installa-
tion it is necessary to observe security requirements. In case of doubt concerning the safe installation and use of the product, please contact the
manufacturer or its representative.
• The installation works must be carried out only trained and qualified personnel.
• Make sure that the connection of electrical network data are equivalent to the product sticker on the device housing.
• Power cable should correspond to power of the unit (see. Selection of the power supply cable and security device).
• The unit must be connected according to the electrical connection scheme which is provided in this document (see. Electrical wiring diagram)
and as shown in the picture under the control box cover.
• It is necessary to connect an external protection device (circuit breaker or protector) the current of which is selected according to the table (see.
Selection of the power supply cable and security device).
• The unit must be secured by earthing.
• Connect control box and remote control panel (see. The electric wiring diagram).
• Connect the electric heater to control box.

For the ventilation unit to work efficiently, once a year perform the inspection of the entire ventilation system, i.e. ensure that the air intake gratings
and air supply devices are not contaminated. Inspect if the air duct system is not contaminated. If necessary, clean these devices or replace them
with the new.
• Fault removal works shall be performed only by trained and qualified personnel.
• Before start of repair works, ENSURE THAT the unit is connected from the supply voltage and wait unit the fan motor stops and the heating ele-
ments cool down.
• Follow the above safety requirements.
The unit switches-off:
• Check if voltage and current of the mains correspond to the requirements indicated in the product label.
• Check for power availability to the unit.
• Upon elimination of power supply faults, switch-on the unit again.
• Check if the alarm signal is displayed on the remote controller. When the cause is found (see the section Indication of the remote controller alarm
signals and PCB indication), solve it and reconnect the unit.
The fan does not rotate:
• Check if the fuses on control board are not blown.
• Check the settings in the remote controller (fan rotation speed, time, date, event, etc.).
• Check if the alarm signal is on.
Decreased air flow:
• Check the settings in the remote controller (fan rotation speed, time, date, event, etc.).
• Check if the air intake damper is not closed.
• Check if the air filter is not contaminated.
• Check if the fan needs to be cleaned.
• Check if the ventilation system needs to be cleaned.
