Water Storage Control Switch

[HullyGully]

I bought a HEIGHR MODEL HT 70AB tank level control switch

 

There was no instructions how to install in the box

 

On the tank i connect two large teminals B1 and B2 which shut off the pump if the water in the tank get low

 

My question is how do I connect to the pump, the pump has Live, Neutral and maybe an earth

 

So please advise how to connect the two cables to the pump side

 

Also at the tank end does it matter which is live or neutral

It depends on what you want to do with the switch

B1 B2 are wiring it as a sump pump A1 A2 are the normal wiring fo filling a domestic tank.

 

 The wiring diagram shows a switched neutral, I would usually switch the line connection.

 

connect neutral and Earth to the pump, line to the switch, switched line from the switch.
 

the wiring is the same as a sump pump or fill pump just different terminals on the switch.
