Traps - replacement (steam systems
only)
The main and auxiliary traps are installed upstream of the
condensate shutoff valve on units that use steam as the energy
source.
The traps are designed to maintain the flow of
condensate with the rise and fall of the float as changes in
condensate level occur within the body of the trap. If the
traps are not functioning properly and must be replaced,
follow the procedure outlined below.
ƽ ƽ WARNING
The combination of electricity and water
can pose a very dangerous situation. Turn
off / disconnect all electric power before
attempting any maintenance procedure.
1. Follow Steps 1 through 5 of the shutdown procedure
(page 10) to take the unit off-line before attempting to
replace the main or auxiliary traps.
2. The exact location of the traps can differ depending on
the unit. Reference the CAD drawing supplied with the
unit to identify the location of the traps on the unit.
3. Carefully break the joint on the inlet side of the trap.
4. Carefully break the joint on the outlet side of the trap.
5. Remove and examine the trap.
6. If the trap is not functioning properly, replace it
