Safety instructions and precautions
Device is manufactured in compliance with the following directives:
Machinery Directive, 2006/42/EC;
Low Voltage Directive, EEC 2006/95;
Electromagnetic Compatibility Directive, 2004/108/EC;
Ecodesign Directive, No 1253/2014.
Read this instruction very carefully before installing and using this equipment. Installation, connection and maintenance should be carried out
by a qualifed technician and in accordance with the local rules and legal acts.
The company shall take no responsibility for the injuries suffered by the people or for the damaged property, if the safety requirements are not
followed or the device is modifed without the permission of the manufacturer.
Main safety rules
Danger
• Before performing any electricity or maintenance tasks make sure, that the device is disconnected from the mains, that all
moving parts of the device have stopped.
• Make sure that the fans can not be entered through air ducts or branch openings.
• If you notice liquids on electric parts or connections that bear voltage, stop the operation of the appliance.
• Do not plug the device into the mains, that differs from the one indicated on the label or on the housing.
• Voltage of the mains should comply with the electrotechnical parameters indicated on the label.
• 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 qualifed 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.
• Do not touch heating elements until they haven’t cooled down.
• Some devices are heavy, thus one should be very careful while transporting and installing. Use suitable lifting equipment.
• While connecting electricity to the mains a circuit breaker of suitable size is necessary.
Warning!
• If the device is installed in a cold environment, make sure that all connections and tubes are properly isolated. Intake and
discharge air ducts should be isolated in all cases.
• Openings of the ducts should be covered during transportation and installation.
• Make sure not to damage the heater when connecting the piping of the water heater. For tightening up, use a wrench/spanner.
Before starting the equipment
• make sure, that there are no strange objects inside;
• manually check whether fans are not stuck or blocked;
• if rotary heat exchanger is installed in the device, make sure that it is not stuck or blocked;
• check the grounding;
• make sure that all components and accessories are connected in accordance with the project or provided instructions.
Danger: Fumes
"Salda Antifrost" system uses dis-balancing of the air flow 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-fred boilers and heaters, freplaces, continuous flow 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 off "Salda Antifrost" and use an
external preheater for heat exchanger anti-frost protection (see "Salda Antifrost" function on the Remote controller manual).
