must be consistent between a minimum of 6.0 inches (14.92 mb) and a maximum of 12.0 inches
(29.9 mb) water column (W.C.) pressure.
2) Liquid Propane (L.P.) Gas
Dryers made for use with L.P. gas have the gas valve’s internal pressure regulator blocked open so
that the gas pressure must be regulated upstream of the dryer. The pressure measured at each
gas valve pressure tap must be a consistent 10.5 inches (26.1 mb) water column. There is no
regulator or regulation 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.

3. Piping Connections
ALL components/materials must conform to National Fuel Gas Code Specifications ANSI Z223.1-LATEST
EDITION, or in Canada, CAN/CGA-B149.1-M91 (Natural Gas) or CAN/CGA-B149.2-M91 (Liquid
Propane [L.P.] Gas) or LATEST EDITION (for General Installation and Gas Plumbing), as well as local
codes and ordinances and must be done by a qualified professional. It is important that gas pressure
regulators meet applicable pressure requirements, and that gas meters be rated for the total amount of
ALL the appliance BTUs being supplied.
The dryer is provided with a 3/8-inch N.P.T. inlet pipe connection located at the right side of the base of the
dryer. The minimum pipe size (supply line) to the dryer is 3/8-inch N.P.T. For ease in servicing, the gas
supply line of each dryer must have its own shutoff valve.
IMPORTANT: The gas supply line to each dryer must be a minimum of 3/8-inch (9.5 mm). DO
NOT REDUCE THIS PIPE SIZE REQUIREMENT.
The size of the main gas supply line (header) will vary depending on the distance this line travels from the
gas meter or, in the case of L.P. gas, the supply tank, other gas-operated appliances on the same line, etc.
Specific information regarding supply line size should be determined by the gas supplier.
NOTE: Undersized gas supply piping can create a low or inconsistent pressure, which will result in
erratic operation of the burner ignition system.
22
Consistent gas pressure is essential at ALL gas connections. It is recommended that a 1/2-inch (12.7 mm)
pipe gas loop be installed in the supply line servicing a bank of dryers. An in-line pressure regulator must
be installed in the gas supply line (header) if the (natural) gas pressure exceeds 12.0 inches (29.9 mb) of
water column (W.C.) pressure. Refer to the illustrations on the previous page.
NOTE: A water column test pressure of 3.5 inches (8.7 mb) for natural gas and 10.5 inches (26.1 mb)
for liquid propane (L.P.) dryers is required at the gas valve pressure tap of each dryer for
proper and safe operation.
A 1/8-inch N.P.T. plugged tap, accessible for a test gauge connection, must be installed in the main gas
supply line immediately upstream of each dryer.
IMPORTANT: Pipe joint compounds that resist the action of natural gas and L.P. gas must be used.
IMPORTANT: Test ALL connections for leaks by brushing on a soapy water solution (liquid
detergent works well).
WARNING: NEVER TEST FOR LEAKS WITH A FLAME!!!
ALL components/materials must conform to National Fuel Gas Code Specifications ANSI Z223.1-LATEST
EDITION, or in Canada, CAN/CGA-B149.1-M91 (Natural Gas) or CAN/CGA-B149.2-M91 (L.P. Gas) or
LATEST EDITION (for General Installation and Gas Plumbing), as well as local codes and ordinances and
must be done by a qualified professional. It is important that gas pressure regulators meet applicable
pressure requirements, and that gas meters be rated for the total amount of ALL the appliance BTUs being
supplied.
IMPORTANT: The dryer and its individual shutoff valve must be disconnected from the gas supply
piping system during any pressure testing of that system at test pressures in excess of
1/2 psig (3.5 kPa).
NOTE: The dryer must be isolated from the gas supply piping system by closing its individual manual
shutoff valve during any pressure test of the gas supply system at test pressures equal to or less
than 1/2 psig (3.5 kPa).
23
H. PREPARATION FOR OPERATION/START-UP
The following items should be checked before attempting to operate the dryer:
1. Read ALL “CAUTION,” “WARNING,” and “DIRECTION” labels attached to the dryer.
2. Check incoming supply voltage to be sure that it is the same as indicated on the dryer data label affixed to
the left side panel area behind the top control (access) door.
3. GAS MODELS - check to assure that the dryer is connected to the type of heat/gas indicated on the dryer
data label.
4. GAS AND ELECTRIC MODELS - the sail switch damper assembly was installed and adjusted at the
factory prior to shipping. However, each sail switch adjustment must be checked to assure that this
important safety control is functioning.
5. Check bolts, nuts, screws, terminals, and fittings for tightness.
6. GAS MODELS - be sure that ALL gas shutoff valves are in the open position.
7. Check that the back guard panel and the electrical box cover have been replaced.
8. Check the lint drawer to assure that it is closed and secured in place.
IMPORTANT: If during installation the lint door safety chain was disconnected, it must be
reconnected or personal injury may result.
9. Rotate the basket (tumbler/drum) by hand to be sure it moves freely.
10. Check terminals and fittings for security.
24
I. PREOPERATIONAL TESTS
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.
1. Turn on electric power to the dryer.
2. Refer to the Operating Instructions for starting your particular model dryer.
3. GAS MODELS ONLY
a. 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.
NOTE: Gas model dryers are equipped with a Direct Spark Ignition (DSI) system, which has internal
diagnostics. If ignition is not established after the first attempt, the heat circuit in the DSI
module will lockout until it is manually reset. To reset the DSI system, open and close the main
door and restart the dryer.
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.
4. Make a complete operational check of ALL safety related circuits:
a. Door Switch(es)
b. Hi-Limit Thermostats
c. Cycling Thermostat
d. GAS AND ELECTRIC MODELS ONLY - Sail Switch
NOTE: The sail switch can be checked for proper operation by opening the lint door while heating
circuit (gas burner/electric oven) is active (on). The heating unit should shut off within a few
seconds. If not, make necessary adjustments to the sail switch.
5. 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.
6. The dryer should be operated through one (1) complete cycle to assure that ALL components are functioning
properly.
25
J. SHUT DOWN INSTRUCTIONS
If the dryer is to be shut down (taken out of service) for a period of time, the following must be performed:
1. Discontinue power to the dryer either at the external disconnect switch or the circuit breaker.
2. Discontinue the heat supply:
a. GAS MODELS...discontinue the gas supply.
1) SHUT OFF external gas supply shutoff valve.

SECTION VI
ROUTINE MAINTENANCE
A. CLEANING
A program and/or schedule should be established for periodic inspection, cleaning, and removal of lint from
various areas of the dryer, as well as throughout the ductwork system. The frequency of cleaning can best be
determined from experience at each location. Maximum operating efficiency is dependent upon proper air
circulation. The accumulation of lint can restrict this airflow. If the guidelines in this section are met, an ADC
dryer will provide many years of efficient, trouble free, and most importantly, safe operation.
WARNING: LINT FROM MOST FABRICS IS HIGHLY COMBUSTIBLE. THE
ACCUMULATION OF LINT CAN CREATE A POTENTIAL FIRE HAZARD.
WARNING: KEEP DRYER AREA CLEAR AND FREE FROM COMBUSTIBLE
MATERIALS, GASOLINE, AND OTHER FLAMMABLE VAPORS AND
LIQUIDS.
NOTE: Suggested time intervals shown are for average usage which is considered six (6) to eight (8)
operational (running) hours per day.
IMPORTANT: Dryer produces combustible lint and must be exhausted to the outdoors. Every 6
months, inspect the exhaust ducting and remove any lint build up.
SUGGESTED CLEANING SCHEDULE
EVERY THIRD OR FOURTH LOAD
Clean the lint drawer every third or fourth load. A clogged lint drawer will cause poor dryer performance. The
lint drawer is located on the lower front of the dryer. Inspect lint screen and replace if torn.
NOTE: The frequency of cleaning the lint drawer can best be determined from experience at each
location.
WEEKLY
Clean lint accumulation from lint chamber, thermostat, and microprocessor temperature sensor (sensor bracket)
area.
WARNING: TO AVOID THE HAZARD OF ELECTRICAL SHOCK, DISCONTINUE
ELECTRICAL SUPPLY TO THE DRYER.
30
90 DAYS
Inspect and remove lint accumulation in customer furnished exhaust ductwork system from dryer’s internal
exhaust ducting.
WARNING: THE ACCUMULATION OF LINT IN THE EXHAUST DUCTWORK CAN
CREATE A POTENTIAL FIRE HAZARD.
WARNING: DO NOT OBSTRUCT THE FLOW OF COMBUSTION AND VENTILATION
AIR.
