c. Disconnect pressure switch hose from
condensate trap.
d. Disconnect outside condensate compression
fitting from condensate trap.
e. Using pliers, release spring clip securing the
overflow switch to condensate trap body and
remove the switch. Note that the switch has
factory applied silicon adhesive seal, which may
have to be carefully cut all around to facilitate
the switch removal.
f. Using pliers, release spring clip securing
condensate trap body to the heat exchanger
bottom drain connection.
g. First, pull the trap downwards to release from
the heat exchanger. Second, pull the trap end
from left side jacket panel sealing grommet and

h. To reinstall the trap, reverse above steps.
i. If the original condensate overflow switch is
to be re-used, follow the appropriate switch
removal steps from Condensate Overflow
Switch Removal and Replacement procedure
above.
j. Insure that fresh silicon sealant is applied to
the overflow switch threads and the switch is
properly oriented relative to the trap body - the
arrow molded into the switch hex side end
must face down for proper switch operation.
See Figure 47 “Condensate Overflow Switch
Orientation” for details.
k. Insure that pressure switch hose is reconnected
to the trap.
l. Restore power supply to boiler. Fill up the
trap (see Section V “Condensate Disposal”)
