* The lowest temperatures can only be achieved when the Tecal 140 is used with
a chilled water supply which has a maximum pressure of 6 metres of water.
However, the chilled water supply must not be switched on when the set
temperature is above 40°C as this can lead to damage to the block.

Working conditions
The Tecal unit is designed to work safely under the following conditions:
Ambient temperature range
5°C to 40°C
Humidity
Up to 95% relative humidity, non-condensing
Note:
The control specifications quoted are for an ambient temperature
range of 10°C to 30°C. The specification may deteriorate outside this range
but the unit will still work safely.
Radio frequency interference tested and passed to EN50081-1.
Immunity Tested and passed to EN50082-1
