3L PRESSURE TANK
The installation of a small 3L pressure tank after the pump and PRESSCONTROL in the system is recommended. This reduces
water hammer and pump start and stop cycle, increasing the operating life for your ECO-MXA and reducing start up wear.
By decreasing the pump's start/stop cycling with a 3L expansion tank, this then helps to decrease the total power consumption
significantly.
The pressure tank should be precharged at a slightly lower value than the restart pressure calibration value of the PRESSCONTROL
device. The PRESSCONTROL is calibrated at 1.5 bar (22PSI), precharge the pressure tank at approximately 1.2 bar (18PSI).
For systems with minimal delivery demands, e.g. a glass of water, ice-making refrigerator, filter system, UV system
inverse, osmosis systems or old systems with small losses a 3L pressure tank is mandatory.

WATER HAMMER
Water hammer is a pressure surge or wave caused when a fluid in motion is forced to stop or change direction suddenly. Water
hammer commonly occurs when a valve closes suddenly at an end of a pipeline system, and a pressure wave propagates in
the pipe. This pressure wave can cause major problems, from noise and vibration to pump failure, with the installation of the
pressure tank, the effects of the water hammer pulses can be removed.
Valve closed - water is still
Valve open - water is moving
through the valve
System with Ceramic taps, solenoid mixing valve (these are fitted in washing machines & dish washers etc) or copper
pipes must have a 3L pressure tank installed to absorb water hammer!
