15. Reassemble the side panels and lower front panel by following step 12 in reverse order (Figure 7-47 to
7-53).
Note: the side panels go on prior to the lower front panel.
16. It is recommended that the hot tank be descaled periodically (frequency varies by mineral content).
Only the use of descaling agents that are compatible with 304 grade stainless steel are recommended. The
use of the descaling agents must be in accordance with the manufacturer’s safety instructions and recom-
mendations and performed by properly trained personnel. Note: ensure the hot tank is empty and drain
plug and cap are in place (Figure 7-54). Using a funnel, add the descaling solution to the hot tank, filling
up to the top of the inlet (approx 38.7oz /1100ml) (Figure 7-55). Allow time for the solution to descale.
Drain and dispose of solution according to the manufacturer’s instructions (refer to step 4 for draining the
hot tank).
