Warnings
• Connection of electricity and maintenance of the device should be performed only by a qualified 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-fired boilers and heaters, fireplaces, 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).
