Menu 5. Once hot water is being drained, check the follow-
ing:
• Steam condensing on the bottom of the cabinet.
Correct by lowering the drain line or adding DRAIN
TEMPERING.
• Flash steam entering the steam cylinder compart-
ment due to inadequate drain line.
• Flash steam entering the electrical compartment if
the knockout for the control wires isn’t sealed. This
should be sealed even if there doesn’t appear to be
any steam entering into the compartment. If conduit
is not used with the controls wiring, install black plas-
tic fingered bushing and completely seal with RTV
Silicone.
• Water must drain from unit freely. If there are restric-
tions in the drain line, it will send hot water/steam up
into the CABINET DRAIN and/or the OVERFLOW
TUBE which will pool inside the cabinet and could
leak out of the unit onto the floor.
