The Foca control set is a suitable solution for adjusting the pump operating time. By installing this control set on the pump and adjusting it precisely, the water pressure can be controlled up to 7 floors. For this purpose, we open one of the upper floor valves by 50 percent and turn the volume of the control set to higher numbers. When the yellow light of the control set turns on and gives the opening command to the pump, we stop turning. In this way, the control set is adjusted for our building facilities. When we open the water tap, the water flow enters the control set with the initial pressure and moves the one-way valve in the direction of the flow. The magnetic piece, which is installed in the upper part of the one-way valve, is electrified by stimulating the sensor on the board and the command to turn on the pump is issued. Possible problems that may occur for this control set: 1- Damage or rupture of the diaphragm Repair: Replace the diaphragm 2- Dirt and sedimentation of the one-way valve Repair: Clean the one-way valve 3- Burnt or damaged electrical board Repair: Replace the electrical board Contact us: www.i-9.ir
