Principle of Operation : -

The Shower pump (Automatic home pressure boosting system) is fitted in series to the water pipeline between the overhead tank and the first tap or shower. The system basically consists of a booster pump and an automatic switch. The pump adds high pressure to the water flowing through outlets like taps, shower heads, jet massage units, closets, etc. Suitable pump may be selected depending on the requirement. The automatic switch switches ON the pump when the tap is opened and switches OFF the pump when the tap is closed. Thus, whenever the water flow in the pipeline starts, the Shower pump gets into action and maintains a high pressure. When no tap or shower is in use, the pump is switched OFF and it remains in the stand - by mode.


Features:-

The latest technology in home pressure boosting eliminates the need for conventional and bulky pressure tanks. Automatically switches ON and OFF whenever taps and showers are opened and closed. Intelligent and reliable electronic circuit is the brain behind this operation. Built - in- dry - running protection saves the pump from failure during absence of water. Consumers very little power. Automatic low voltage sensor prevents the system from damage. Totally maintenance free compared to conventional systems.

TYPE OF DEFECT
CAUSES DEPENDING ON THE UNIT
CAUSES NOT DEPENDING ON THE UNIT
- The pump does not start
-The electronic card is broken
- Voltage failure
- Pump jammed
- Electric cables inverted (Line/motor)
- The pump does not stop
- The electronic card is broken
- The flow detector is blocked in the        upper position.
- The reset button is blocked
- The pump does not provide sufficient    pressure
- Presence of leaks which are higher    than the minimum flow 0.6 1/min
- Intermittent pump working
- The electronic card is broken
- The pump does not provide sufficient    pressure
- Presence of leaks which are lower       than the minimum flow 0.6 1/min
- The pump is jammed
- The electronic card is broken
- The pump provides a pressure which    is lower than the restarting pressure
- Water failure
- Suction problems

UNIT STARTING AND WORKING
On the cover back and inside the terminal board, a drawing shows how to make connections correctly. The cable used shoud have 6 mm min. and 9 mm max. ouside diameter, In order to guarantee the water tight enclosure of the box, the four screws on its box must be tightly screwed.
 
STARTING
When the unit is connected to the electrical network, the green led "Power On" lights up and the yellow led "Pump On"(pump in operation) indicates that the pump has been started.
The pump continues to operate for a few seconds enabling the system to fill in the pipes and to reach the required pressure. If this lapse is insufficient, the red LED "Failure" lights, up. In this event, keep the "Restart" buttom pressed and wait, with a tap opened, until the red led is off.
 
FUNCTIONING
The starting operation achieved, the until is programmed to perform all the pumps control operations automatically. When particular operational breakdowns occur, such as water failure, obstruction of the suction pipe etc., the unit recognizes the breakdown and red led "Failure" lights up; at the same time a stop signal is sent to the pump to prevent damages caused by its working in the absence of water. Rectification of the failures that have caused the blockage, allows the system to be restarted by pressing the "Restart" button.
