6.1 Principle of operation
6.2 NTC thermistor
NTC1
Exhaust temperature
NTC2
Ambient temperature
Resettable
150
°c cut out
Non-resettable
120
°c cut out
Resistance is monitored by the controller of both NTC thermistors to determine the dryness of the load.
Once the desired dryness is achieved the cool down period begins.
6.3 Temperature limiters
There are 3 limiters (thermostats) located and mounted to the element carrier. Two are resettable and
one is a non resettable thermal cut-out.
6.4 Heater elements
A 1200 watt and a 550-watt element are used which are controlled indvidually by the relays in the
electronic controller.
High
Both elements
1750 watts
Medium
Large element
1200 watts
Low
Small element
550 watts
The ambient air is drawn into the cabinet by
the fan which is attached to the motor.
This air pressurises the cabinet and is forced
over the heating element and heated.
The heated air then enters from the rear of
the drum and meets with the clothes, the
humid hot air exits through the lint filter and
exhaust duct.
