• Ensure the condensate drain line is
not blocked by pouring water through
the plug port on the condensate drain
assembly. The water should flow out of
the end of the drain line. If water does
not appear at the end of the drain line,
contact a qualified service technician to
inspect and clean the condensate line.
• To fill the condensate drain assembly,
if necessary, remove the plug from the
condensate assembly. Slowly pour
water into the trap assembly until water
appears at the end of the drain line.
Stop filling and replace plug.
