2.  Allow condensate to flow into the condensate recovery pump, and operate the pump 

automatically to blow off the newly-built piping downstream of the pump. 

(1)  Allow condensate to flow into the 

pump in order to prepare it for 
operation.

(2)  Switch on the pump control panel. The power lamp will light up. 
(3)  Turn on the breaker switch in the control panel. Put the select switch for pump 

operation to the “automatic” position.
