4.
Heat Input
(For Gas Dryers) – This describes the heat
input in British thermal units per hour (Btu/hr) or kilowatts
(kW).
5.
Orifice Size
(For Gas Dryers) – Gives the number drill
size used.
6.
Electric Service
– This describes the voltage and
current rating for a particular model.
7.
Gas Manifold Pressure
(For Gas Dryers) – This
describes the manifold pressure taken at the gas valve
tap.
Procedure for Functional Check
of Replacement Components ________
DSI Module
Theory of Operation: Start the drying cycle. When the gas
burner ignites within the chosen trial for ignition time
(8-seconds), the flame sensor detects gas burner flame
and signals the DSI module to keep the gas valve open as
long as there is a call for heat. The DSI module will
“LOCKOUT” if the gas burner flame is not sensed at the end
of the trial for ignition period. The trial for ignition period will
be repeated for a total of three retries/trials (the initial try and
two more retries/trials). If the flame is not sensed at the end
of the third retry/trial (inter-purge period of 30-seconds), the
DSI module will “LOCKOUT” (a red L.E.D. diagnostic
indicator will flash).
An unlit red L.E.D. diagnostic indicator indicates normal
operation.
A lit green L.E.D. diagnostic indicator indicates dryer
controller is calling for heat and that all interlocks have been
satisfied.
When contacting ADC, certain information is required to
ensure proper service/parts information from ADC. This
information is on the data label affixed to the right side panel
area at the rear of the dryer. When contacting ADC, please
have the model number and serial number available.
1.
Model Number
– This describes the style of dryer and
type of heat (gas, electric, or steam).
2.
Serial Number
– Allows the manufacturer to gather
information on your particular dryer.
3.
Type of Heat
– This describes the type of heat for your
particular dryer, gas (either natural gas or L.P. gas),
electric, or steam.
When cleaning the dryer cabinet(s), avoid using harsh
abrasives. A product intended for the cleaning of
appliances is recommended.
Adjustments
7 Days After Installation
and Every Six Months Thereafter
Inspect bolts, nuts, screws, setscrews, grounding
connections, and nonpermanent gas connections (unions,
shutoff valves, and orifices). Motor and drive belt should be
examined. Cracked or seriously frayed belt should be
replaced. Tighten loose belts when necessary. Complete
operational check of controls and main valves. Complete
operational check of all safety devices (door switch, lint
drawer switch, sail switch, burner and exhaust hi-limit
thermostats).
Lubrication
The motor bearings and under normal/most conditions the
tumbler bearings are permanently lubricated. It is physically
possible to relubricate the tumbler bearings if you choose
to do so even though this practice is not necessary. Use
Shell Alvania #2 grease or its equivalent. The tumbler
bearings used in the dryer do not have a grease fitting.
Provisions are made in the bearing housing for the addition
of a grease fitting, which can be obtained elsewhere, or
from ADC by ordering kit P/N 882159 (includes two fittings).
