American Dryer Corp. D170 - Manual (Page 20)

20 JLA Limited 113376-4
Compressed Air Requirements _______
The dryer requires an external supply of compressed air (2.5
cfh [cubic feet per hour] at 80 psi [0.07 cmh [cubic meters
per hour] at 5.51 bar for gas models and 3.25 cfh at 80 psi
[0.09 cmh at 5.51 bar] for steam models). For steam models,
compressed air is necessary for the air operated steam
damper. On both the steam models as well as the gas
models, compressed air is necessary/required for blower air
jet operation to clean lint from the blower motor impellor (fan)
(squirrel cage).

Dryers
Shaded areas are stated in metric equivalents
Air Regulation
No air regulation or air filtration is provided with the dryer.
External regulation/filtration of 80 psi (5.51 bar) must be
provided. It is suggested that a regulator/filter gauge
arrangement be added to the compressed air line just before
the dryer connection. This is necessary to ensure that correct
and clean air pressure is achieved.
Air Connection
Air connection to this system is a 1/8” F.P.T. as per the
illustration below.

Shutdown Instructions ________________
If the dryer is to be shutdown (taken out of service) for a
period of time, the following must be performed:
Discontinue power to the dryer either at the external
disconnect switch or the circuit breaker.
Discontinue the heat supply:
Gas Models – Discontinue the gas supply. Shut off external
gas supply shutoff valve.
Steam Models – Discontinue the steam supply. Shut off
external (location furnished) shutoff valve.
Note
To check for proper sail switch operation, open
the main door and while holding main door switch
plunger in, start the dryer. The dryer should start but the
heat circuit should not be activated (on). If the heat
(burner) does activate, shut the dryer off and make the
necessary adjustments.
Reversing tumbler dryers should never be operated with less
than a 112 lb (51 kg) load (dry weight), since the load’s weight
affects tumbler coast time during a direction reversal
command. It is important that the tumbler come to a complete
stop prior to starting in opposite direction.
Microprocessor Controller (Computer)
Dryer Models
Spin and dwell (stop) times are not adjustable in the Automatic
Mode and have been preprogrammed into the microprocessor
controller (computer) for 150-seconds spin time in the forward
direction and 120-seconds in the reverse direction with a
5-second dwell (stop) time.
Spin and dwell (stop) times are adjustable in the Manual
(timed) Mode.
Tumbler Coating
The tumbler is treated with a protective coating. We suggest
dampening old garments or cloth material with a solution of
water and nonflammable mild detergent and tumbling them
in the tumbler to remove this coating.
Each dryer should be operated through 1 complete cycle to
ensure that no further adjustments are necessary and that
all components are functioning properly.
Make a complete operational check of all operating controls.
Microprocessor Controller (Computer)
Programs/Selections
Each microprocessor controller (computer) has been
preprogrammed by the factory with the most commonly used
parameter (program) selections. If computer changes are
required, refer to the computer programming manual, which
was shipped with the dryer.
Dual Timer Dryers
Turn drying timer knob for a time of 20 minutes.
Select “High Temp.”
Push “Push To Start” button.
To stop dryer, open the main door.
