4.2 Hydraulic installation
• Install a pressure relief valve sufficient to limit the system pressure below the maximum
working pressure of the pump and tank (the minimum of the two). The pressure relief
valve must be plumbed to a drain to prevent damage due to flooding.
• Check that the sum of the pressure intake (for example, for the connection with a
municipal line or pressure tank) and the maximum pressure of the pump does not exceed
the value of the maximum permitted operating pressure of the controller or of the pump
(the minimum of the two).
• In cases where the water level is below the suction of the pump (lifting water), install a
check valve (foot valve) on the suction of the pump to make sure that the pump stays
primed.
• Install a gate valve to allow maintenance of the controller and pump or of the pressure
tank.
• It is advisable to install a tap for use during commissioning of the system if there is not
already an outlet near the pump.
• The controller plus electric pump can be used to connect the system directly to the
municipal supply line or to take water from a primary water supply tank.
• If connecting to a municipal supply, follow the applicable provisions set by the authorities
having jurisdiction.
• It is advisable to install a pressure switch on the suction side for turning off the pump if
there is low pressure in the in-coming supply line. Protects against dry running.
• If connecting to a primary water supply tank, it is advisable to install a float for turning off
the pump when there is no water. Protects against dry running.
• Refer to the instruction manual of the pump for further information.
The following images show a single pump system and a multi-pump system respectively.
