Elbi Hydrophore AFV

ELBI series AFV hydrophores

Vertical design pressure vessel; factory pre-charged air pressure 1.5bar, Operating temperature from -10C to +99C, Available in volumes from 50L - 500L, Color - blue,

Do not exceed the maximum working pressure and temperature of the expansion tank; provide the system with appropriate control to prevent exceeding these parameters,Provide a suitable drainage system that prevents extensive damage in case of a crack and water leakage from the expansion tank,

When installing, provide a proper water and air leakage system,The manufacturer is not responsible for external forces (traffic, wind, earthquakes) affecting the expansion tank, so it should be evaluated before installing the tank,Before installation, clarify the main parameters of the system, Qualified personnel should regularly check this system,The manufacturer is not liable for any losses resulting from incorrect installation of the equipment,If the maximum working pressure and temperature of the expansion tank are exceeded, the manufacturer has the right to refuse warranty claims,If different fluids are used in the system, check their compatibility,The installation site must be protected from unauthorized persons - only authorized personnel are allowed in this area,The equipment must be equipped with appropriate grounding or isolated from the heating system with a dielectric connection,

If the hydrophore is installed in an existing system, make sure that the power supply to the pump control panel is turned off and that the system is completely drained or the water supply is closed,2, If a simple pressure vessel (without a membrane) is installed in the existing system, turn off the air supply devices, level indicators, etc.,3, Remove the tank from the packaging, remove the protective cap (see, 4, no, 6) from the air valve, Check the existing pressure and make sure it is slightly lower than the pressure at which the pressure switch operates, If necessary, adjust the pressure in the tank, Once done, screw the protective cap back on,4, Install the tank as close as possible to the pressure switch to minimize pressure losses, Examples of tank installation are shown in figures 1, 2, and 3,5, Connect the tank to the main water pipe or to the pump outlet, following all installation rules,6, It is recommended to install a safety valve and adjust it according to the maximum working pressure of the system,7, Connect the power supply to the pump control panel only after the tank installation is complete,8, Turn on the pump and fill the system with water until the pressure switch operates and the pump turns off,9, To vent the system, repeatedly open and close the faucet farthest from the tank, 10, Open one or more faucets to empty the tank, If a pause is detected between emptying the tank and turning on the pump, either slightly increase the pressure switch activation pressure or reduce the air pressure in the pressure vessel (see point 3),11, Repeat steps 8, 9, and 10 until this pause is no longer detected,12, Check all connections and make sure there are no water leaks,13, The system is ready for use if all the above points have been successfully completed,14, Regularly check the existing pressure in the tank during its operation and fill it with air if necessary,When performing maintenance, first turn off all electrical equipment related to the system and check that there is no pressure and temperature hazardous to health in the system, Qualified personnel should check all heating system elements at least once a year, The manufacturer has already pre-charged the air in the pressure vessel, Changes in air pressure in the expansion tank should only be made by a certified plumber, The newly set pressure should be recorded on the expansion tank,
