SAFETY FEATURES
All T.S.S. series brewers are equipped with several safety features to ensure that the unit does not operate should a
problem arise. These safety features are described below.
•
A secondary water level probe prevents that water tank from overfilling should lime and calcium build-up
accumulate on the primary water level probe.
•
The control board is designed so that the water heater switches off if a short circuit or open circuit is detected on
the temperature probe.
•
All T.S.S. models are capable of heating the water to a temperature close to the boiling point (210°F). In the
event of a calibration change, low atmospheric pressure or a fault in the control board, the unit is equipped with
an overflow cup for additional safety. Should this cup fill, power will be switched off to all the valves and the
heater, preventing water leaking from the machine. This overflow prevention system is described in detail below.
OVERFLOW SAFETY PROTECTION
In the event of the water temperature exceeding the boiling
point, or the water tank overflowing due to a control board
failure, any excess water will safely drip into the overflow safety
cup. This cup is located at the back of the water tank, as
illustrated in the drawing (left). The magnetic float inside the
overflow cup will deactivate the switch and shut off the power to
the control board. This will in turn switch off the power to the
inlet valve, the outlet valve and the water heater.
NOTE:
Should the overflow cup be full, no lights will be
illuminated on the front selection panel. The only light that
will be on is the light in the main power switch.
If an overflow does occur, follow these simple steps to correct
it:
1. Loosen the screw that secures the overflow cup
access panel at the rear of the machine.
2. Lift and remove the overflow cup access panel out of its retaining bracket, empty the water, and re-install
it.
3. Rotate the temperature dial (marked TEMP) on the control board back three marks to lower the
temperature.
4. Drain one or two liters of hot water through the hot water spigot. This will drop the temperature of the
water currently inside the tank.
5. Allow tank to re-hear, and check the temperature with a thermometer. Adjust the dial until the desired
temperature is obtained.
If the symptoms persist, check the control board and/or the water temperature probe.
