INSTALLATION INSTRUCTIONS 

 

DAVIES, CRAIG EWP

®

 (ELECTRIC WATER PUMP) AND PUMP CONTROL 

 

Congratulations  on  your purchase of the Davies, Craig  EWP

®

 80  &  EWP

®

  -FAN Digital  Controller which is 

designed  to  replace  the  existing  belt  driven  mechanical  water  pump  of  your  engine  and  to  switch  your 
Thermatic

®

 Fan on and off. The Digital controller will vary the speed of your EWP

®

 in response to the engine 

temperature and switch the Thermatic

®

 fan at 3°c above the target set point. The EWP

®

 will continue running 

after hot engine shut down to prevent damaging heat soak.  When your EWP

®

 is used to replace the mechanical 

pump,  you  will  notice  an  increase  in  engine  power  and  torque,  especially  at  high  engine  speeds.    Automatic 
gear changes, both up and down, will be smoother.  

PLEASE READ THESE INSTRUCTIONS IN THEIR ENTIRETY BEFORE YOU START WORK.       

ALSO NOTE THAT THE EWP IS A „CIRCULATION‟ PUMP IDEAL FOR „CLOSED CIRCUIT‟ OPERATION SIMILAR 

TO AN AUTOMOTIVE COOLING SYSTEM. IT IS NOT A „SELF-PRIMING‟ PUMP AND THEREFORE WILL NOT 

OPERATE WITHOUT A POSITIVE „HEAD‟ IN AN „OPEN‟ SYSTEM.
