13.0 – STEAM DISPENSE WAND and WATER DISPENSE ARM:
See Drawing of Draw-off Tap
Steam Dispense Wand:
The steam dispense wand is made from stainless steel and has a chromed-brass steam nozzle
attached to the end. It can be swivelled into different positions due to a ball-fitting, held within
the steam-wand coupling. The coupling screws onto the underside of the tap body using a thin
PTFE washer to form a seal. The ball-fitting rotates within the coupling and is held in position by
an “O” ring, a spring and brass retainer.
The most common problem is ware & tare on the “O” ring which if excessive, can allow steam to
escape through the coupling. Also, the spring can eventually ware or break causing the steam
wand to become “floppy”.
The “O” ring and/or the spring can be replaced by unscrewing the steam wand from the tap body
and stripping apart. Remove all traces of the worn “O” ring and clean the ball fitting before
putting back together with the new “O” ring.
IMPORTANT:
To allow the ball-fitting to rotate smoothly, it is essential that both the ball-fitting
and the “O” ring and smeared with food-grade silicone grease (Pt No: LKT5), before re-connecting
the wand to the draw-off tap.
Water Dispense Arm:
See Drawing of Draw-off Tap
The water dispense arm is made from stainless steel and connects to the underside of the water
draw-off tap. It can be swivelled into different positions by unlocking the dispense-arm nut,
moving to the desired position and re-tightening the nut.
There is a white PTFE dispense arm washer which forms a water-tight seal, where the dispense
arm attaches to the tap body. Over time, the washer may ware and require replacement (see
drawing of Dispense Arm).
