CONNECTION OF THE ELECTRIC CABLE TO THE ELECTRICITY
Instalation of electric feeder - This feeder must be separetely protected by a safety fuse according to the
specifi c electric stream which depends on the wattage of the instaled device. Check the wattage on the label
at the back of the device. Connect the device directly to the electricity but you must put the switch between
the device and electric net. The switch must be placed in min. distance 3 mm between the particular contacts
according to the standards and loading. The feeder of grounding (yellow-green) cannot be interrupted by this
switch. In every case feeding cable must be placed so that no point of the cable will reach the temperature
which is 50°C higher than the temperature of the surrounding. Before connecting the device check that:
• safety fuse of the feeder and inner mains can stand the loading of the device (see label of the matrix)
• mains are equipped with eff ective grounding according to standards (ČSN) and conditions given by law
• socket or switch of the feed is well accessible from device

• Water hardness must be in range 0,5 - 5 ° French degree.
IF HIGHER, IT IS NECESSARY USE WATER SOFTENING SYSTEM.
• Water pressure must be within range 50 - 250kPa.
• Volume of chlorine in the water shall not be higher than 10ppm, or you risk bath surface damage
• Acidity of water must be higher than 7 pH.
• Electrical conductivity: 50 - 2000uS/cm (20°C)
• The connection must be made according to directive EN 1717 and with valid to national directives for aqua-
culture.
