Caution
This dryer produces combustible lint and must
!
be exhausted to the outdoors. Every 6 months,
inspect the exhaust ducting and remove any lint buildup.
Dryer Enclosure Requirements ______
Bulkheads and partitions should be made of noncombustible material.
Leveling Dryer
The dryer is equipped with four (4) leveling legs, one (1) at each corner of the base. Two (2) are located at the rear of the dryer base, and two (2) are located in the lint chamber (coop). To increase bearing life and improve efficiency, the dryer should be tilted slightly to the rear.
Location Requirements ______________
Before installing the dryer, be sure the location conforms to local codes and ordinances. In the absence of such codes or ordinances the location must conform with the National Fuel Gas Code ANSI.Z223.1 LATEST EDITION, or in Canada, the installation must conform to applicable Canadian Standards: 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).
The dryer must be installed on a sound level floor capable of supporting its weight. Carpeting must be removed from the floor area that the dryer is to rest on.
Important
“The dryer must be installed on noncombustible
!

113242-3 7
Page 8
Fresh Air Supply Requirements___
When the dryer is operating, it draws in room air, heats it, passes this air through the tumbler, and exhausts it out of the building. Therefore, the room air must be continually replenished from the outdoors. If the make-up air is inadequate, drying time and drying efficiency will be adversely affected. Ignition problems and sail switch “fluttering” problems may result, as well as premature motor failure from overheating. The dryer must be installed with provisions for adequate combustion and make-up air supply.
Air supply (make-up air) must be given careful consideration to ensure proper performance of each dryer. As a general rule, an unrestricted air entrance from the outdoors (atmosphere) measuring a minimum size of 8-inches by 12-inches (20.32 cm by 30.5 cm) is required for each dryer. (Based on 1 square inch per 1,000 Btus.)
To compensate for the use of registers or louvers used over the openings, this area must be increased by approximately thirty-three percent (33%). Make-up air openings should not be located in an area directly near where exhaust vents exit the building.
It is not necessary to have a separate make-up air opening for each dryer. Common make-up air openings are acceptable. However, they must be set up in such a manner that the make-up air is distributed equally to all the dryers.
Note
Component failure due to dry cleaning solvent
!
fumes will void the warranty.
Exhaust Requirements ______________
Exhaust ductwork should be designed and installed by a qualified professional. Improperly sized ductwork will create excessive back pressure, which results in slow drying, increased use of energy, and shutdown of the burner by the airflow (sail) switch, burner hi-limits, or lint chamber hi-limit protector thermostat. The dryer must be installed with a proper exhaust duct connection to the outside.
Where possible, it is suggested to provide a separate (single) exhaust duct for each dryer.
Caution
This dryer produces combustible lint and must
!
be exhausted to the outdoors.
Improperly sized or installed exhaust ductwork can create a potential fire hazard. Dryer must be exhausted to the outdoors.
The exhaust ductwork should be laid out in such a way that the ductwork travels as directly as possible to the outdoors with as few turns as possible. The shape of the ductwork is not critical so long as the minimum cross section area is provided. Single or independent dryer venting is recommended.
It is suggested that the use of 90° turns be avoided; use 30° or 45° angles instead.
The ductwork should be smooth inside with no projections from sheet metal screws or other obstructions, which will collect lint. When adding ducts, the ducts to be added should overlap the duct to which it is connected. All ductwork joints must be taped to prevent moisture and lint from escaping into the building. Additionally, inspection doors should be installed at strategic points in the exhaust ductwork for periodic inspection and cleaning.
Important
When connecting ductwork to the dryer exhaust
!
duct, be sure that when screws are used they do
not restrict the operation (both opening and closing) of the
A = 12-inches B = 15-inches
damper.
Note
When the exhaust ductwork passes through a
EXAMPLE: For a bank of 4 dryers, 2 unrestricted openings measuring 12-inches by 15-inches (30.5 cm by 38.1 cm) are acceptable.
Allowances must be made for remote or constricting passageways or where dryers are located at excessive altitudes or predominantly low pressure areas.
Important
Make-up air must be provided from a source free
!
of dry cleaning solvent fumes. Make-up air that is contaminated by dry cleaning solvent fumes will result in irreparable damage to the motors and other dryer components.
8 113242-3
!
wall, ceiling, or roof made of combustible materials, the opening must be 2-inches (5.08 cm) larger than the duct (all the way around). The duct must be centered within this opening.
To protect the outside end of the horizontal ductwork from the weather, a 90° elbow bent downward should be installed where the exhaust exits the building. If the ductwork travels vertically up through the roof, it should be protected from the weather by using a 180° turn to point the opening downward. In either case, allow at least twice the diameter of the duct between the duct opening and the nearest obstruction (i.e., roof or ground level).
Page 9
Important
Do not use screens, louvers, or caps on the
!
outside opening of the exhaust ductwork.
Exhaust back pressure measured by a manometer at the dryer exhaust duct area must be no less than 0 and must not exceed 0.3 inches (0.74 mb) of water column (W.C.).
For extended ductwork runs, the cross section area of the duct can only be increased to an extent. For extended ductwork runs, a professional heating, ventilating, and air-conditioning (HVAC) firm should be consulted for proper venting information.
Single Dryer Venting
Important
For exhaust duct runs over 85 feet (25.9 meters) a
!
Horizontal Venting
When a single 8-inch (20.32 cm) horizontal vent is used, the ductwork to the outlet cannot exceed 85 feet (25.9 meters), refer to Illus. A below. This calculation of 85 feet (25.9 meters) compensates or allows for the use of a maximum of only one (1) elbow, (which is the outside outlet protection).
minimum size of 10-inches (25.4 cm) must be used.
Vertical Venting
When vertical single 8-inch (20.32 cm) venting is used (refer to Illus. B below), the ductwork from the dryer to the outside outlet cannot exceed 55 feet (16.7 meters). This calculation compensates for the use of a maximum of three (3) elbows including the two (2) elbows creating the 180° (turned downward) outside outlet.
Illus. B
Illus. A
If the length of the duct run or quantity of elbows used exceeds the above noted specifications, the cross-sectional area of the ductwork must be increased in proportion to the number of elbows or duct run added.
113242-3 9
Page 10
Multiple Dryer (Common) Venting
If it is not feasible to provide separate exhaust ducts for each dryer, ducts for individual dryers may be channeled into a common main duct. Each dryer is provided with a back draft damper. The individual ducts should enter the bottom or side of the main duct at an angle not more than 45° in the direction of the airflow.
The main common duct may be any shape so long as the minimum cross-sectional area is provided. The main duct should be tapered with the diameter increasing before each individual 8-inch (20.32 cm) duct is added (refer to Illus. C for horizontal venting and Illus. D for vertical venting).
Important
No more than four (4) dryers
!
maximum should be connected to
one (1) main common duct with a vertical run.
Note
Distance between dryer single ducts
!
being connected to the main common duct must be a minimum width of 34-1/4” (87 cm).
Ductwork should be laid out in such a manner where allowances are made at rear area of the dryer for removal of rear service panels or guards.
Horizontal Venting
Illus. C
Vertical Venting
Illus. D
The illustrations show the minimum cross section area for multiple dryer venting. These figures must be increased in proportion if the main duct run from the last dryer to where it exhausts has numerous elbows or is unusually long.

Steam Information ___________________
It is your responsibility to have all plumbing connections made by a qualified professional to ensure that the steam plumbing installation is adequate and conforms with local and state regulations or codes.
Care must be exercised when leveling steam dryers into final position. After leveling the dryer, check the downward pitch of the heat exchanger from front to rear with a level. Likewise, check the downward pitch of the return condensate manifold toward its outlet part. Absence of these downward pitches will result in probable water hammer and premature heat exchanger fracture and leakage.
The presence of condensate in the steam will cause water hammer and subsequent heat exchanger failure. The steam supply connection must be taken from the top of a well-dripped steam main. If the supply run-out to the dryer exceeds 20 feet (6.1 meters), it should be dripped just before the control valve with a proper trap and dirt pocket.
Important
Failure to comply with the requirements
!
stipulated in this manual can result in component
failure, which will void the warranty.
Important
Coil failure due to improper pH level will void the

Installation Instructions
To ensure an adequate supply of steam is provided, be sure that the steam supply lines and steam return lines are sized and laid out as stipulated in this manual. Inadequate steam supply lines and steam return lines or improper steam plumbing will result in poor performance and can cause component failure. Clean, dry steam must be provided to the dryer.

(piston) damper system, which requires an
external supply of air (80 psi ± 10 psi [5.51 bar ± 0.68 bar]).
Steam Coil pH Level
The normal pH level for copper type steam coils must be maintained between a value of 8.5 to 9.5. For steel type steam coils the pH level must be maintained between a value of 9.5 to 10.5. These limits are set to limit the acid attack of the steam coils.
Important
Steam coil failure due to water hammer by wet
!
steam will void the warranty.
The pressure of the condensate in the steam supply line will cause water hammer and subsequent heat exchanger (steam coil) failure. The steam supply connection into the main supply line must be made with a minimum 10-inch (25.4 cm) riser. This will prevent any condensate from draining towards the dryer.
The steam supply line to the dryer must include a 12-inch (30.48 cm) riser along with a drip trap and check valve. This will prevent any condensate from entering the steam coil.
16 113242-3
Page 17
Flexible hoses or couplings must be used. The dryer vibrates slightly when it runs and this will cause the steam coil connections to crack if they are hard piped to the supply and return mains.
Shutoff valves for each dryer should be installed in the supply line, return line, and drip trap return line. This will allow the dryer to be isolated from the supply main and the return main if the dryer needs maintenance work.
Install an inverted bucket steam trap and check valve at least 12-inches (30.48 cm) below the steam coil as close to the coil as possible.
A trap with a capacity of 350 lbs (160 kg) of condensate per hour at 125 psi (8.61 bar) is needed for each unit.
The supply line and the return line should be insulated. This will save energy and provide for the safety of the operator and maintenance personnel.
Water pockets in the supply line, caused by low points, will provide wet steam to the coil possibly causing steam coil damage. All horizontal runs of steam supply piping should be pitched 1/4-inch for every 1 foot (0.30 meters) back towards the steam supply header causing the condensate in the line to drain to the header. Install a bypass trap in any low point to eliminate wet steam.

Steam Damper Air System Connections
This dryer is manufactured with a pneumatic (piston) damper system, which requires an external supply of compressed air. The air connection is made to the steam damper solenoid valve, which is located at the rear inner top area of the dryer just in front of the electric service relay box.
Air Requirements
There is no air requirement for dryers with the Electromechanical Steam Damper Option.
113242-3 17
Page 18
Steam Damper System Operation
The steam damper, as shown in the illustration (above right), allows the coil to stay constantly charged eliminating repeated expansion and contraction. When the damper is opened, the air immediately passes through the already hot coil, providing instant heat to start the drying process. When the damper is closed, ambient air is drawn directly into the basket (tumbler), allowing a rapid cool down.
Steam Damper Air Piston (Flow Control) Operation Adjustment
Damper operation was tested and adjusted prior to shipping at 80 psi (5.51 bar). If damper air adjustment is necessary, locate the flow control valve and make the necessary adjustments as noted below. Diagram 1 shows the damper in the heating (open) mode, allowing heat into the basket (tumbler).
Diagram 2 shows the damper in the cool down (closed) mode, pulling ambient air directly into the basket (tumbler) without passing through the coils.

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.
Turn on electric power to the dryer. Refer to the Operating Instructions for starting your particular
model dryer.
Gas Models Only
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.
The dryer is equipped with a Direct Spark Ignition (DSI) system, the DSI control module has internal diagnostics. If ignition is not established within three (3) attempts, the heat circuit in the DSI control module will “LOCK OUT” until manually reset. To reset the DSI system, open and close the main door and restart the dryer.
Note
Water column (W.C.) pressure requirements
!
(measured at the pressure tap of the gas valve body): Natural Gas ______________ 3.5 Inches (8.7 mb) W.C. Liquid Propane (L.P.) Gas ___ 10.5 Inches (26.1 mb) W.C.
Important
There is no regulator provided in a liquid propane
!
(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 Thermostat
Basket Coating
The basket (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 basket (tumbler) to remove this coating.
Check the electric service phase sequence (3-phase [3ø] models only). While the dryer is operating, check to see if the blower wheel (impellor/fan) is rotating in the proper direction. Looking from the front, the blower wheel (impellor/fan) should spin in the clockwise (CW) direction. If it is, the phasing is correct. If the phasing is incorrect, reverse two (2) of the three (3) leads at connections L1, L2, and L3 of the power supply to the dryer.
Important
If the blower wheel (impellor/fan) is rotating in the
!
wrong direction, this will not only drastically reduce drying efficiency, but it can also cause premature component failure.

Routine Maintenance ________________

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, a JLA 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.
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 buildup.
Warranty Information ________________

Returning Warranty Cards

Before any dryer leaves the factory test area, a warranty card is placed on the back side of the main door glass. These warranty cards are intended to serve the customer where we record the individual installation date and warranty information to better serve you should you file a warranty claim.
If a warranty card did not come with your dryer, contact the JLA Warranty Department.
Important
A separate warranty card must be completed and
!
returned for each individual dryer.
Note
Be sure to include the installation date when
!
returning the warranty card(s).

Warranty

For a copy of the JLA commercial warranty covering your particular dryer(s), contact the JLA reseller from whom you purchased the equipment and request a dryer warranty form. If the reseller cannot be contacted or is unknown, warranty information can be obtained from JLA by contacting the JLA Warranty Department.
Note
Whenever contacting JLA for warranty
!
information, be sure to have the dryer’s model number and serial number available so that your inquiry can be handled in an expeditious manner.
Suggested Cleaning Schedule
Every Third or Fourth Load
Clean the lint screen every third or fourth load. A clogged lint screen will cause poor dryer performance. The lint screen is located in a drawer below the main door. Open the lint drawer, brush or vacuum the lint off the lint screen, and remove the lint. Inspect lint screen and replace if torn.
Note
The frequency of cleaning the lint screen 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.
Steam Dryers
Clean the steam coil fins. We suggest using compressed air and a vacuum cleaner with brush attachment.
Warning
When cleaning steam coil fins, be careful not to
!
bend the fins. If fins are bent, straighten by using a fin comb, which is available from local air conditioning supply houses.

90 Days
Inspect and remove lint accumulation in customer furnished exhaust ductwork system and from dryer’s internal exhaust ducting.
Warning
The accumulation of lint in the exhaust ductwork
!
can create a potential fire hazard.
Do not obstruct the flow of combustion and ventilation air.
Inspect and remove any lint accumulation, which can cause the back draft damper to bind or stick.
Note
A back draft damper that is sticking partially
!
closed can result in slow drying and shutdown of
heat circuit safety switches or thermostats.
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 6 Months Thereafter
Inspect bolts, nuts, screws, setscrews, grounding connections, and nonpermanent gas connections (unions, shutoff valves, and orifices). Motor and drive belts should be examined. Cracked or seriously frayed belts should be replaced. Tighten loose V-belts when necessary. Complete operational check of controls and valves. Complete operational check of all safety devices (door switches, lint drawer switch, sail switch, burner, and hi-limit thermostats).
Data Label Information ______________
When contacting JLA, certain information is required to ensure proper service/parts information from JLA. This information is on the data label affixed to the left side panel area behind the top control (access) door. When contacting JLA please have the model number and serial number available.
Lubrication ___________________________
The motor bearings, idler bearings, and under normal/most conditions the basket (tumbler) bearings are permanently lubricated. It is physically possible to relubricate the basket (tumbler) bearings if you choose to do so even though this practice is not necessary. Use Shell Alvania #2 or its equivalent. The basket (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 by ordering kit Part No. 882159, which includes two (2) fittings.

Lint Drawer Removal_________

To remove the lint drawer from the dryer pull drawer out approximately halfway. Rotate/move lint drawer stop hinge (refer to the illustration) downward and pull the drawer out.

Phase 7 Non-Coin Models
Upon completing installation of the replacement microprocessor controller (computer) board, reestablish power to the dryer.
Start the drying cycle by pressing any of the preset cycles in letters A-F.
Verify that the applicable indicator lights on the microprocessor controller (computer) board are lit. (Refer to the illustration below.)
Verify that the applicable indicator lights on the microprocessor controller (computer) board are lit. (Refer to the illustration below.)
For Models with Johnson Direct Spark Ignition (DSI) Controller (G760)
Theory of Operation:
Start the drying cycle. When the gas burner ignites within the chosen trial for ignition time (6-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 “LOCK OUT” 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 (3) retries/trials (the initial try and two [2] more retries/trials). If the flame is not sensed at the end of the third retry/trial (inter­purge period of 30-seconds) the DSI module will “LOCK OUT”

(light emitting diode [L.E.D.] diagnostic indicator flashes). A steady light emitting diode (L.E.D.) indicator indicates
normal operation. No L.E.D. indicator indicates a power or an internal failure
has occurred.
For Models with Fenwal Controls Direct Spark Ignition (DSI) Module (128937)
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 “LOCK OUT” 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 (3) retries/trials (the initial try and two [2] 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 “LOCK OUT” (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.
Manual Reset Burner Hi-limit Instructions __________________________

Phase 7

This dryer was manufactured with a manual reset burner hi-limit thermostat, which is monitored by the Phase 7 computer. If the burner hi-limit is open prior to the start of the drying cycle, the dryer will start momentarily and then shut down, the Phase 7 computer will display “BURNER HIGH LIMIT FAULT” with an audio indication.
If the burner hi-limit opens during a drying cycle, the Phase 7 computer will also display the same error code described above, along with an audio indication. If the drum temperature is above 100° F (38° C), the dryer will continue to run with no heat for 3 minutes or until the drum temperature has dropped below 100° F (38° C). The clear/stop button on the Phase 7 keyboard (touch pad) must be pressed to clear the error condition. The open burner hi-limit must be reset “manually” prior to the start of the next cycle.

Dual Timer

This dryer was manufactured with a manual reset burner hi-limit thermostat. If the burner hi-limit is open prior to the start of the drying cycle, or during the cycle, the dryer will not recognize the open state of the burner hi-limit and will start or continue through the drying cycle with no heat. Manual reset hi-limit must be reset manually.
This hi-temperature condition may be caused due to a restricted exhaust, poor airflow, or improper burner operation.
The location of the burner hi-limit is on the right side of the burner box, looking at the burner from the back of the dryer.
Warning
Discontinue power to dryer before attempting to
!
reset hi-limit.
