4.3.2 Ice Bank Level Check
The water level in the ice bank may require periodic topping
off to ensure optimal operation. Check and refill it as indi‐
cated below.
The fill tube is located behind the front splash panel and is
capped with a red plug.
The small, black, overflow tube, connected to an internal
standpipe, will emit water during manual refill when the
water level reaches the full mark.

NOTE: When the fill tube is in its stored position (as shown
in Fig. 4‐2) it also serves as a 'sight glass' indicating the bank
water level.
1) Remove the drip tray and splash panel to reveal the front
of the ice bank.
2) Observe the fill tube and the water level in it. If the water
level is below the top of the tube arc, add water to the ice
bank.
3) Add filtered store water through the fill tube after
extending it from its storage position and removing the red
cap. Add water until a trickle runs out of the black overflow
tube.
4) Cap the fill tube and return it to its storage position.
