Heating Elements
The water tank contains one 2000 watt - 29 (ohm) heating
element.
One solid state relay controls the AC voltage to the heating
element. Remember to isolate the element from the system
prior to performing an ohms check.
High Temperature Limit Switch – Water
Rated at 210°F/99°C
In the event that the water tank temperature exceeds
210°F/99°C ±5°F/3°C, the high temperature limit switch opens
the control circuit to the solid state relays and cuts the voltage
to the heating elements. The high temperature limit switch is
auto-reset capable, so when the temperature cools to
180°F/82°C ±10°F/5°C, the high temperature limit switch will
be reset and allow the heater to be activated.
Draining the Water Tank
The steam tank must be drained prior to draining the water
tank. For instructions on draining the steam tank, please see
page 5-18.
1. Disconnect the power supply to the machine.
2. Disconnect the water supply at the source.
3. Open the water drain valve under the machine (left
side). The black handle should be vertical.
4. Loosen the line between the water tank and the brew
water valve input. Use a ½” wrench.
5. After the water finishes draining, tighten the line
between the water tank and the brew water valve. Use a
½” wrench.
6. Close the water drain valve. The black handle should be
perpendicular to the machine.
7. Reconnect the water supply at the source.
8. Reconnect the power supply to the machine.
