5. AUTOMATICS
5.1 ELEMENTS OF AUTOMATICS
Electric connections may only be made by well-trained electricians, and according to:
• Occupational health and safety regulations
• Assembly instructions
• Technical documentation for each of the automatic elements
NOTE Before starting the assembly process and connecting the system, familiarize yourself with the original documentation attached to the
automatic devices.

6. START-UP, OPERATION, MAINTENANCE
6.1 START-UP/PUTTING INTO OPERATION
• Prior to any installation or maintenance works, disconnect the device from the power supply and secure it against accidental power-up.
• Use filters in the hydraulic system. Before you connect the hydraulic lines (especially supply lines) to the device, you should clean/rinse
the installation by draining a few litres out of it.
• Install vent valves at the highest point of the installation.
• Install cut-off valves directly behind the device, so it can be easily disassembled.
• Secure the device against pressure increase according to the permitted maximum pressure value of 232psi.
• Hydraulic pipes need to be free from any stresses and loads.
• Prior to the first start-up of the heater, check the hydraulic connections (vent and collector air-tightness, installed fittings).
• Prior to the first start-up of the heater, check the electric connections (connection of automatic devices, power supply, fan).
• It is suggested to use additional external current differential protection.
6.2 OPERATION AND MAINTENANCE
• Device casing does not require any maintenance.
• Heat exchanger needs to be regularly cleaned of dirt and grease. Especially before the heating season, the heat exchanger needs to be
cleaned with the use of compressed air on the side of the air guides (but the device does not need to be disassembled). Pay attention
to the exchanger’s lamellas, as these are delicate.
• If lamellas bend, straighten them with a special tool.
• The fan motor does not require any maintenance. It may only require cleaning of the protective mesh, fan blades and dust and grease
deposits.
• If the device is not used for a long time, disconnect the voltage supply.
• Heat exchanger does not have fire protection.
• It is recommended to periodically blow through the heat exchanger, preferably with compressed air.
• The heat exchanger can freeze (fracture) when the room temperature falls below 0°C and the heating agent temperature decreases at
the same time.
• The level of air pollutants should meet the criteria allowable concentrations of pollutants in indoor air, for non-industrial areas, the level
of dust concentration up to 0.3 g / m³. It is forbidden to use device for the duration of the construction works except for the start-up of
the system.
• The equipment must be operated in rooms used throughout the year, and in which there is no condensation (large fluctuations in
temperature, especially below the dew point of the moisture content).
• The device should not be exposed to direct UV rays.
• The device should be operated at the supply water temperature up to 200 °F with working fan.
