• If any liquids on electric parts or connections that bear voltage are noticed, stop the operation of the device.
• Do not plug the device into the mains that differ from the one indicated on the label or on the housing.
• Voltage of the mains should comply with the electro technical parameters indicated on the label.
• The device should be earthed in accordance with the regulations on the installation of electric devices. Turning on and using unearthed
device is not allowed. Follow the requirements specified on the device’s labels that indicate danger.
Warnings
• Connection of electricity and maintenance of the device should be performed by the qualified personnel only and in accordance with the
manufacturer’s instructions and safety requirements.

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 up the device
• make sure, that there are no strange objects inside;
• manually check fans to make sure they are not stuck or blocked;

Danger: Fumes
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 Antifrost and use an external preheater for heat exchanger anti-frost protection (see Antifrost
function on the Remote controller manual).
