Note

 – For correct operation the NRV assembly (item 16) must be fitted with the orientation 

groove to the left (inlet port side) as shown in Fig. 12.

For correct operation of the flow switch, the reed must be secured to the body as detailed  

below.
Firstly feed the tie warp through the retainer on the reed switch, ensuring that the tie wrap  

serrations are facing outwards (see Fig. 13).

Now locate the reed switch within the body groove as highlighted X-X in Fig. 14 below, and  
feed the tie wrap through the second catch. 
The tie wrap can now be pulled tight to secure the reed and the excess cut to length as shown    
in Fig. 15.

INITIAL OPERATING INSTRUCTIONS

• 

Do not run pump dry.   Allow the liquid to be pumped to enter the pump body thus ensuring   

the seal is lubricated before switching the pump on.  Failure to do this will damage the seal.

• 

Carefully check pump and pipework for leaks whilst pump running and stationary before  

leaving the installation unattended.
