On the front of the electrical box is a switch.  To switch one way is to start the 
unit automatically, and to switch the other is manual.  This switch has a sticker 
showing which way is which. 
Turn the switch to automatic, after ensuring that the foot valve is in water. 
 

Primer pump starts first: 

 

At left is the primer pump.  You will hear this pump 
start and it will prime the main pump which will not 
start immediately.  Do not worry if the main pump 
does not immediately start as it will come on line 
once priming is complete. 
 
This primer pump has a dual purpose – one is to 
prime the main pump at start-up, and the other is to 
prime the main pump during operation as required.  
This process is automated and requires no operator 
intervention once the switch is turned on. 
 

It can take a short time for the primer pump to fully prime the system and you 
just need to wait for this to happen. 
 

Main pump will then start: 

Shown at left is the main pump within the system.  
This pump is behind and to the right of the blue 
primer pump and is named Leo on the top of the 
pump. 
 
This pump will start automatically once the system 
is primed and it is correct for it to start.  No operator 
action is required to have this pump start once the 
switch is turned on. 
This pump is in continual running whilst the system 
is in use.
