SECTION 4: BLEEDING THE EWP
®
For the EWP
®
80 ensure it is orientated correctly as shown below before
continuing.
NOTE: This orientation is a temporary requirement for the purpose of bleeding
the pump and ensuring there is no air entrapped within the seal housing of the
pump. The pump can be set-up in another orientation upon completion of the
bleeding procedure.
FOR ALL EWPS:
1. Fill the engine cooling system with appropriate coolant.
2. Turn heater on full.
3. With the radiator cap off, hardwire the EWP
®
directly to the vehicle’s battery
or a 12v power source. Air trapped in the cooling system will exit at the top
of the radiator.
4. Turn on engine and idle.
5. Top up the radiator with coolant with the EWP
®
running until all air is
eliminated. Waterless coolants increase the load on an EWP and may reduce
pump life.
6. Turn off engine.
7. Replace the radiator cap and reconnect the EWP
®
to the wiring system
supplied.
