Condenser and Drain Functions
The SteamCraft 10 drain piping has five branches: one from each steam generator, one
from each cooking compartment, and one from the door gutter in the front panel. All
five branches combine at the drain fitting: which exits through the bottom of the unit.
• The electric heater model 24-CEA-10 has two steam generators, two drain lines, and
two drain solenoid valves (upper and lower). The drains lines from each generator
connect to the drain fitting at the bottom of the unit.
• The gas -fired model 24-CGA-10, has one steam generator and one drain valve. There
are four drain pipe branches in these units.
1. The door gutter drain is a simple tube running from the gutter to the drain fitting.
2. Each cooking compartment has a drain line which runs from the condenser at the
back of the compartment to the drain fitting at the bottom of the unit.
3. During the steaming cycle, a stream of cold water sprays into the condenser of the
operating compartment(s). This cold spray condenses the warm vapors in the drain,
promoting drainage of fluids, condensate and vapor from the cooking compartment.
4. Each steam generator drain is controlled by a drain solenoid valve. When the
ON/OFF switch is set to the OFF position, the drain valve opens as part of the rinse
cycle, and remains open to completely drain each steam generator. The drain valve
operations are explained on page 81.
Condenser Operation
Condenser valve operation differs slightly between the model 24-CEA-10 and model
24-CGA-10 SteamCraft 10's. The difference has no effect on cooking performance or
operating efficiency. When troubleshooting the drain or condenser components, the
differences may cause some confusion. Refer to Figures 5-11 and 5-12.
A. In the 24-CGA-10 models, the condenser solenoid valve is energized through the
TIMED/MANUAL switch only. The condenser solenoid valve opens only when the
TIMED/MANUAL switch is set to MANUAL, or when a cooking time is set in
TIMED mode. It does not open during the preheat cycle.
B. In the 24-CEA-10 models, the condenser solenoid valve is energized through the
TIMED/MANUAL switch or the Preheat Thermostat. The condenser solenoid valve
opens whenever the heating elements are energized: during both steaming and
preheat cycles.
