The SK-30 controller is designed to control the pump by turning on and off the device. Turning depends on a drop in water pressure in the water system below the minimum pressure on the machine and the flow of flow in the pipe on which the SK-30 automatic is installed. Disabling depends on the retention of water flow in the pipe on which the SK-30 machine is installed.
The device turns on the pump when unscrewing the tap with water or opening the sprinklers, and turns off when the tap or sprinklers are closed. The device has a drywall protection functions (pump without water), i.e. in the absence of water in the SK-30 device, the machine turns the pump to prevent it from being destroyed. The device can cooperate directly connected to pumps, the engines of which do not consume more electricity than 30 A.
The device protects the installation against flooding due to low leaks.
The device is intended for working with clean water without mechanical pollution.
Characteristics:
- Built -in check valve
- Supply protection
- Built -in pressure gauge
- Protection against overvoltage and low voltage
- Manual switch "Auto / Reset"
- Signaling diode Power supply "Power on"
- Diode signaling the work of the "Pump on" pump
- Signaling the lack of water, the flashing "Water Shortage (Flash)" LED
- Signaling the frequent switching on and off the flashing LED "Auto / Reset"
- Automatic tuning for installation
Installation
The installation of the device can be carried out by a person who knows the user manual and having appropriate hydraulic and electrical qualifications.
The device can work in installations in which clean water is pumped without iron or iron flax content. The work of the device with dirty water will lead to its failure.
The device must be installed on the pressure side of the pump in the vertical position between the pump and the first water receiver (see Fig.).
To increase the flexibility of work, install a small diaphragm, e.g. 5 liters.
When installing, pay attention to the direction of water flow through the device. On the housing there is an embossed arrow showing the correct direction of flow.
If the device is to work in an installation where the pressure is over 10 bar, a pressure reducer should be installed in front of the device.
Connections of the SK-30 machine with pipes are best sealed with Teflon tape. The device on the device can be adjusted in the range of 0–10 bar. The device can work with a pump that will create a pressure not less than 2 bar at the input to the SK-30 machine.
Due to the possible disturbances of the flow between the pump and the device, do not mount the check valves between these devices.
