Slayer Single Group (Classic) transducer replacement
UPDATE: Honeywell transducers have been phased out.
If you still have new legacy Honeywell transducers on hand, see below for replacement instructions.
Objective:
Replace Honeywell transducer on Single Group Classic.
Time:
15-20 minutes
Parts:
99004-17001 Honeywell Transducer Assembly.
Tools:
#2 Philips Head Screw Driver
1/2" Wrench
Step 1:
- Turn off machine and depressurize steam tank.
Step 2:
- Remove cup tray and rear panel to expose transducer and electronics.
Unplug old transducer from board and feed it through the gap in electronics shield.
Step 3:
- Use a 1/2" wrench to remove the copper line and transducer from steam tank.
Step 4:
Feed the new transducer cable through the heat shield gap. Attach the Molex to the transducer port on the board.
Tip: Make sure to route the cable so it doesn't rest against the steam tank. Feed the cable behind the pump hose and tuck it neatly.
Step 4:
- Install assembled transducer and copper line to fitting on steam tank. Finger-tight with an additional 1/4 turn with a wrench.
Tighten compression fittings appropriately: Finger tight followed by a quarter turn with correct wrench. If more tightening is necessary, proceed with small incremental turns.
- Attach wire to the transducer and zip-tie it against the panel.
Step 4:
- Turn on machine. Verify ball valve drains are closed.
- Allow autofill cycle to complete.
- Run water through groups to confirm brew group saturation.
- Allow heating cycle to complete and check for leaks once pressurized. Tighten compression fittings if needed.
