• The device should be earthed in accordance with the rules of installation of electric appliances. It is forbidden to turn on and use
unearthed device. Follow the requirements of the device’s labels that indicate Danger.
Warnings
• Connection of electricity and maintenance of the device should be performed only by a qualied personnel, in accordance with the
manufacturer’s instructions and valid safety requirements.
• In order to reduce the risk during installation and maintenance, suitable protective clothes should be worn.
• Beware of sharp angles while performing installation and maintenance tasks.

Danger: Fumes
SaldaAntifrostsystem uses dis-balancing of the air ow and it may cause negative pressure in premises. Great care should be taken
when using at the same time in premises as another heating appliance what depend on the air in premises. Such appliances include
gas, oil, wood or coal-red boilers and heaters, replaces, continuous ow or other water heaters, gas hobs, cookers or ovens which
draw air in from the room and duct exhaust gases out through a chimney or extraction ducting. The heating appliance can be starved
of oxygen, impairing combustion. In exceptional cases harmful gases could be drawn out of the chimney or extraction ducting back
into the room. In this case we strictly recommend to turn o󰀨 SaldaAntifrost and use an external preheater for heat exchanger anti-frost
protection (see SaldaAntifrost function on the Remote controller manual)
