AIR FLOW AND SEALS
Proper air fl ow thru the dryer is essential for normal
operation of the temperature control and safety
systems. There are two separate air fl ows in the dryer:
the enclosed process air and the cooling (ambient) air.
7
The ambient air is drawn thru louvers at the front of the
8
unit (1) by the front blower wheel (2) and then fl ows over
6
the condenser (3) cooling the process air. The ambient
air then exits the dryer thru louvers in the back of the
9
dryer.
The process air is pulled thru the condenser (4) by the
2
rear blower wheel (5) and travels up the rear channel
5
(6) to the electric heater (7) where it is warmed up and
1
drawn into the drum (8) thru a diffuser. The heated
4
process air dries the clothes and then fl ows thru the lint
3
fi lter (9) and into the condenser (4), where it is cooled
down and the moisture condensed out.
The same dry air is then reheated, where it is again
blown thru the drum and clothes, and the cycle begins again (this is a more-or-less continuous process).
If the ambient air fl ow is restricted in anyway, it will decrease the performance of the condenser and
signifi cantly increase drying times.
Proper air fl ow thru the dryer is essential for normal operation of the temperature control and safety
systems. The back cover must be in place for proper airfl ow.
The temperature of the process air rises by passing thru the electric heaters. This heated air enters thru holes
in the back of the drum and dries the clothes load. The air containing moisture is pulled thru the lint fi lter,
where lint is screened by the fi lter, and enters the condenser. The moisture is condensed and the warm air
cycles thru the drum again.
Any air leaks in the enclosed system will result in improper temperatures.
