Preoperational Test __________________
All dryers are thoroughly tested and inspected before leaving
the factory. However, a preoperational test should be
performed before the dryer is publicly used. It is possible that
adjustments have changed in transit or due to marginal location
(installation) conditions. Installer must instruct the user on
how to correctly operate the dryer before leaving.
Turn on electric power to the dryer.
Refer to the operating instructions for starting your particular
model dryer.
Gas Dryers
When a gas dryer is first started (during initial start-up), it has
a tendency not to ignite on the first ignition attempt. This is
because the gas supply piping is filled with air, so it may take
a few minutes for the air to be purged from the lines.
NOTE: During the purging period, check to be sure that all
gas shutoff valves are open.
Gas model dryers are equipped with an ignition system,
which has internal diagnostics. If ignition is not established
after one time, the heat circuit in the ignition module will
attempt two more ignitions (total of three ignition attempts).
If there is no flame after the third ignition attempt, the
module will lock out until it is manually reset. To reset the
ignition system, open and close the main door and restart
the dryer.
A burner gas pressure measurement should be taken at the
gas valve outlet pressure tap of each gas valve to ensure that
the water column pressure is correct and consistent.
NOTE: Water column burner pressure requirements
(measured at the outlet pressure tap of the gas valve body):
Natural Gas ........ 3.5 in WC (8.7 mb).
L.P. Gas .............. 10.5 in WC (26.1 mb).
IMPORTANT: There is no regulator provided in an L.P.
dryer. The water column pressure must be regulated at the
source (L.P. tank) or an external regulator must be added to
each dryer.
Make a complete operational check of all safety related circuits:
Door Switch(es)
Hi-Limit Thermostats
Cycling Thermostats
Sail Switch
Make a complete operational check of all operating controls.
NOTE: If computer program changes are required, refer to
the computer programming section of the manual supplied
with the dryer.
The dryer should be operated through one complete cycle to
ensure that no further adjustments are necessary and that all
components are functioning properly.
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.
Preoperational Instructions __________
Coin Models
Microprocessor Controller (Computer)
When the microprocessor controller (computer) is in the ready
state, the L.C.D. screen will display “FILL” followed by the
amount to start.
Insert coin(s). Once the correct “Amount to Start” has been
inserted, the L.C.D. will display “PUSH”.
Select temperature by pressing “HI,” “LO,” or “PERM PRESS.”
The cycle will start and the L.C.D. will display the Dry Cycle
selected and the remaining time.
The dryer will continue through the drying and cooling cycles,
until the vended time has expired.
NOTE: To stop the dryer, open the main door. Continuation
of the cycle will resume only after the door has been closed
and any of the three temperature selection buttons is
pressed.
Upon completion of the drying and cooling cycles, the tone
(buzzer) will sound and the dryer will go into the Anti-Wrinkle
Mode, if active, for up to 99 minutes, or until the main door or
lint drawer has been opened.
IMPORTANT: For more detailed information regarding the
microprocessor controller (computer) on your dryer, refer to
the microprocessor user’s manual included with the dryer.
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 gas supply (for gas models only):
Shut off external gas supply shutoff valve.
Service / Parts Information __________
Service
Service must be performed by a qualified trained technician,
service agency, or gas supplier. If service is required, contact
the reseller from whom the equipment was purchased. If the
reseller cannot be contacted or is unknown, contact the Service
Department for a reseller in your area.
NOTE: When contacting the Service Department, be sure to
give them the correct model number and serial number so
that your inquiry is handled in an expeditious manner.
Parts
Replacement parts should be purchased from the reseller from
whom the equipment was purchased. If the reseller cannot
be contacted or is unknown, contact the Parts Department for
a reseller in your area. Parts may also be purchased directly
from the factory by calling the Parts Department at (508)
678-9000, FAX in your order at (508) 678-9447, or visit us
online at www.adclaundry.com.
