Draining of the water cooling circuit
This operation must be performed quickly, because without any water
cooling, the pump will overheat after a few minutes and will be in warning
/ hazard mode.
Preliminary operations
Prepare a flexible pipe (A) with a 1/4 NPT quick female connector
(to be connected to the customer compressed air circuit) and
another flexible pipe (B) with a 1/4 NPT male connector.
Connect pipe (A) on the pump, at location of «
IN
» and connect the
other end to a compressed air circuit (200 to 500 kPa).
Connect pipe (B) on the pump, at location «
OUT
» and place the
other end of the pipe in a vessel (total water volume will be less
than one litre).
Draining the water
volume
Inject compressed air into the «
IN
» inlet until the first water volume has
been completely evacuated.
When the water is filled out, quickly stop the pump and disconnect
pipes (A) and (B).

&LEXIBLEPIPE"
As the water circuit is equipped with water valve (normaly closed), emptying
operation must be done when the pump is running (so valves are opened
and regulation disabled).
