Clearance provisions must be made from combustible construction as noted in this manual (refer to Dryer Enclosure Requirements section).

Provisions must be made for adequate clearances for servicing and for operation as noted in this manual (refer to Dryer Enclosure Requirements section).

The dryer must be installed with a proper exhaust duct connection to the outside as noted in this manual (refer to Exhaust Requirements section).

The dryer must be located in an area where correct exhaust venting can be achieved as noted in this manual (refer to Exhaust Requirements section).

The dryer can be moved to its final location while still attached to the skid or with the skid removed. To remove the skid from the dryer, locate and remove the four lag bolt s securing the base of the dryer to the wooden skid. Two are at the rear base, and two are located in the bottom of the lint chamber. To remove the two lag bolts located in the lint chamber area, remove the front panel.

Leveling Dryer

To level the dryer, place 4-inch (10.16 cm) square metal shims or other suitable material under the base pads. It is suggested that the dryer be tilted slightly to the rear.

If more headroom is needed when moving the dryer into position, the top console (module) may be removed.

113375-6 Telephone 01422 822282 7

Page 8

Dryer Enclosure Requirements ______

Even though a 12-inch (30.48 cm) clearance is acceptable, it is recommended that the rear of the dryer be positioned approximately 24-inches (60.96 cm) from the nearest obstruction (i.e., wall) for ease of installation, maintenance, and service. Bulkheads and partitions should be made from noncombustible materials. The clearance between the bulkhead header and the dryer must be a minimum of 4-inches (10.16 cm) and must not extend more than 4-inches (10.16 cm) to the rear of the front. A 2-inch (5.08 cm) clearance is required between the bulkhead facing and the top of the dryer.

To compensate for the use of registers or louvers used over the openings, this make-up air must be increased by approximately thirty-three percent. 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.

Example: For a bank of four dryers, two unrestricted openings measuring 27.7-inches by 30-inches (70.358 cm by 76.2 cm), (11.5 feet

[1.068385 meters2]) are acceptable.

Note

Bulkhead facing should not be installed until after

the dryer is in place. Ceiling area must be located a minimum of 12-inches (30.48 cm) above the dryer top console (module) and 18-inches (45.72 cm) for steam models.

When fire sprinkler systems are located above the dryers, a minimum of 18-inches (45.72 cm) above the dryer console (module) is required. Dryers may be positioned sidewall to sidewall, however, 1 or 2-inches (2.54 or 5.08 cm) is suggested for ease of installation and maintenance. Allowances must be made for the opening and closing of the control door and the lint door.

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 assure proper performance of each dryer. As a general rule, an unrestricted air entrance from the outdoors (atmosphere) of a minimum of 1.4 feet required for each dryer. (Based on 1 inch

(0.13 meters2) is

per 1,000 Btu.)

Allowances must be made for remote or constricting passageways or where dryers are located at excessive altitudes or predominantly low pressure areas.

A = 27.7-inches (70.358 cm) B = 30-inches (76.2 cm)

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.

Note

Component failure due to dry cleaning solvent

fumes will void the warranty.

Exhaust Requirements _______________

General Exhaust Ductwork Information

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 , overheating of the dryer, and shut down of the burner by the airflow (sail) switches, burner hi-limits, or tumbler hi-heat thermostats. The dryer must be installed with a proper exhaust duct connection to the outside.

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.

Note

When dryers are exhausted into a multiple

(common) exhaust line, each dryer must be

supplied with a back draft damper.

The 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. Single or independent dryer venting is recommended.

When single dryer venting is used, the ductwork from the dryer to the outside exhaust outlet should not exceed 20 feet (6.09 meters). In the case of multiple (common) dryer venting, the distance from the last dryer to the outside exhaust outlet should not exceed 20 feet (6.09 meters). The shape of the ductwork is not so critical so long as the minimum cross-sectional area is provided. It is suggested that the use of 90° turns be avoided; use 30° and/or 45° bends/angles instead. The radius of the elbows should preferably be 1-1/2 times the diameter of the duct. Excluding tumbler/dryer elbow connections or elbows used for outside protection from the weather, no more than two elbows should be used in the exhaust duct run. If more than two elbows are used, the cross-sectional area of the ductwork must be increased in proportion to the number of elbows used.

All ductwork should be smooth inside with no projections from sheet metal screws or other obstructions, which will collect lint. When adding ducts, the duct to be added should overlap the duct to which it is to be connected. All ductwork joints must be taped to prevent moisture and lint from escaping into the building. Inspection doors should be installed at strategic points in the exhaust ductwork for periodic inspection and cleaning of lint from the ductwork.

As per the National Fuel Gas Code, “Exhaust ducts for

type 2 clothes dryers shall be constructed of sheet metal

or other noncombustible material. Such ducts shall be

equivalent in strength and corrosion resistance to ducts

made of galvanized sheet steel not less than 26 gauge

(0.0195-inches [0.50 mm]) thick.”

NOTE 1 Opening must be 2-inches (5.08 cm) larger than the duct (all the

way around). The duct must be centered within this opening.

NOTE 2 Distance should be 2 times the diameter of the duct to the nearest

obstruction.

Outside Ductwork Protection

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.

Important

It is recommended that exhaust or booster fans

not be used in the exhaust ductwork system.

Exhaust back pressure measured by a manometer in the exhaust duct must be no less than 0 and must not exceed

0.3 in WC (0.74 mb).

Note

When the exhaust ductwork passes through a

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.

113375-6 Telephone 01422 822282 9

Single Dryer Venting

Where possible, it is suggested to provide a separate exhaust duct for each dryer. The exhaust duct 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. It is suggested that the use of 90° turns in the ducting be avoided; use 30° and/or 45° angles instead. The shape of the exhaust ductwork is not critical so long as the minimum cross section area is provided.

Important

Do not use screens, louvers, or caps on the

outside opening of the exhaust ductwork.

Page 10

Important

The minimum duct size is 16-inches (40.64 cm)

for a round duct and 14-1/4” x 14-1/4” (36.2 cm x

36.2 cm) for a square duct. The duct size must not be reduced anywhere downstream of the dryer.

Exhaust back pressure measured by a manometer at each tumbler exhaust duct area must be no less than 0 and must not exceed 0.3 in WC (0.74 mb).

It is suggested that the ductwork from each dryer not exceed 20 feet (6.09 meters) with no more than two elbows (excluding dryer connections). If the ductwork exceeds 20 feet (6.09 meters) or has numerous elbows, the cross-sectional area of the ductwork must be increased in proportion to the length and number of elbows in it. In calculating duct size, the cross-sectional area of a square or rectangular duct must be increased twenty percent for each additional 20 feet (6.09 meters). The diameter of a round exhaust duct should be increased ten percent for each additional 15 feet (4.57 meters). Each 90° elbow is equivalent to an additional 40 feet (12.19 meters), and each 45° elbow is equivalent to an additional 20 feet (6.09 meters).

Important

For extended ductwork runs, the cross section

area of the ductwork can only be increased to an extent. Maximum proportional ductwork runs cannot exceed 20 feet (6.09 meters) more than the original limitations of 20 feet (6.09 meters) with two elbows. When the ductwork approaches the maximum limits as noted in this manual, a professional HVAC firm should be consulted for proper venting information.

Note

When the exhaust ductwork passes through a

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.

Multiple Dryer (Common) Venting

If it is not feasible to provide separate exhaust ducts for each dryer, ducts from individual dryers may be channeled into a “common main duct.” 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 flow and should be spaced at least 48-3/4” (123.82 cm) apart. The main duct should be tapered, with the diameter increasing before each individual 16-inch (40.54 cm) duct is added.

A = 20 feet (6.09 meters) B = 16-inches (40.64 cm)

NOTE 1 Opening from combustible materials must be 2-inches (5.08 cm)

larger than the duct (all the way around). The duct must be centered within this opening.

NOTE 2 Distance should be 2 times the diameter of the duct to the nearest

obstruction.

C = 20 feet (6.09 meters) D = 16-inches (40.64 cm)

Important

When exhausted into a multiple (common)

exhaust line, a back draft damper must be installed at each dryer duct.

No more than four dryers should be connected to one main common duct.

The main duct may be any shape or cross-sectional area, so long as the minimum cross section area is provided. The illustration on the next page shows the minimum cross section area for multiple dryer round or square venting. These figures must be increased 10 inches centimeters the ratio of duct width to depth should not be greater than 3-1/2 to 1. These figures must be increased in proportion if the main duct run to the last dryer to where it exhausts to the outdoors is unusually long (over 20 feet [6.09 meters]) or has numerous elbows (more than two) in it. In calculating ductwork size, the cross-sectional area of a square or rectangular duct must be increased twenty percent for each additional 20 feet (6.09 meters). The diameter of a round exhaust must be increased ten percent for each additional 20 feet (6.09 meters). Each 90° elbow is equivalent to an additional 40 feet (12.19 meters) and each 45° elbow is equivalent to an additional 20 feet (6.09 meters).

Consistent gas pressure is essential at all gas connections. It is recommended that a 1-inch (2.54 cm) 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 in WC (29.9 mb) pressure.

Steam Information ___________________

Note

A consistent water column test pressure of 3.5 in

WC (8.7 mb) for natural gas and 10.5 in WC (26.1 mb) for L.P. dryers is required at the gas valve pressure tap of each dryer for proper and safe operation.

A 1/8” 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. Test all connections for leaks by brushing on a soapy

water solution (liquid detergent works well). 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).

Warning

Never test for leaks with a flame!!!

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).

TYPICAL NATURAL GAS INSTALLATION

Important

Failure to comply with the requirements

stipulated in this manual can result in component

Important

Steam coil failure due to water hammer by wet

14 JLA Limited 113375-6

Page 15

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 12-inch (30.48 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.

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.

An inverted bucket steam trap with a capacity of 1,200 lb (544 kg) of condensate per hour @ 125 psi (8.62 bar) is required for each unit.

Dryers with optional solenoid valve must be mounted with coil positioned directly above the valve body.

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 (6.35 mm) for every 1 foot (0.31 meters)

back towards the steam supply header causing the

condensate in the line to drain to the header. Inst all a bypass

trap in any low point to eliminate wet steam.

Steam Damper Air System Connections

The 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 of the top console.

Steam Damper System Operation

The steam damper, as shown in the illustration below (Diagram 1), 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 tumbler, allowing a rapid cool down.

Preparation for Operation/Start-Up __

The following items should be checked before attempting to operate the dryer:

• Read all “CAUTION,” “WARNING,” and “DIRECTION” labels attached to the dryer.

• Check incoming supply voltage to be sure that it is the same as indicated on the dryer data label. In the case of 208 VAC or 230/240 VAC, the supply voltage must match the electric service exactly.

• GAS MODELS – check to assure that the dryer is connected to the type of heat/gas indicated on the dryer data label.

• GAS MODELS – the sail switch damper assembly was installed and pre-adjusted at the factory prior to shipping. However, each sail switch adjustment must be checked to assure that this important safety control is functioning.

• GAS MODELS – be sure that all gas shutoff valves are in the open position.

• Be sure that all electric box covers have been replaced.

• Check all service doors to assure that they are closed and secured in place.

• Be sure the lint drawer is securely in place.

Diagram 1 shows the damper in the heating (open) mode, allowing heat into the tumbler.

Diagram 2 shows the damper in the cool down (closed) mode, pulling ambient air directly into the tumbler without passing through the coils.

Note

With the dryer off or with no air supply, the steam

damper is in cool down mode as shown in

Diagram 2.

Steam Damper Air Piston (Flow Control) Operation Adjustment

Although the steam damper operation was tested and adjusted prior to shipping at 80 psi (5.51 bar), steam damper operation must be checked before the dryer is put into operation. Refer to the following page to check steam damper operation. If steam damper adjustment is necessary , locate the flow control valve and make the necessary adjustments as noted below.

Note

Lint drawer must be closed to activate the safety

switch otherwise the dryer will not start.

• Rotate the tumbler (drum) by hand to be sure it moves freely.

• Check bolts, nuts, screws, terminals, and fittings for security.

• STEAM MODELS – check to ensure air supply (80 psi [5.51 bar]) is connected to the dryer.

• STEAM MODELS – check to ensure all steam shutoff valves are open.

• STEAM MODELS – check steam damper operation.

• Check tumbler bearing setscrews to ensure they are all tight.

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.

Turn on electric power to the dryer. Make sure the main door is closed and the lint drawer is

securely in place. Refer to the Operating Instructions for starting your particular

model dryer. Check to ensure that the tumbler starts in the clockwise

direction. Additionally, check the direction of the motorized impellor to ensure that the motorized impellor rotates in the clockwise direction as viewed from the front. If it is, the phasing is correct. If the phasing is incorrect, reverse two of the leads at L1, L2, or L3 of the power supply connections made to the dryer.

16 JLA Limited 113375-6

Page 17

Important

Motorized impellor as viewed from the front must

turn in the clockwise direction, otherwise the dryer efficiency will be drastically reduced and premature component failure can result.

Heat Circuit Operational T est Gas Models

When the dryer is first started (during initial start-up), the burner has a tendency not to ignite on the first attempt. This is because the gas supply piping is filled with air, so it may take a few minutes for this air to be purged from the lines.

The dryer is equipped with a DSI system, which has internal diagnostics. If ignition is not established after three attempts, the heat circuit DSI module will LOCKOUT until it is manually reset. To reset the DSI system, open and close the main door and restart the dryer (press the “START” key).

Note

During the purging period, check to be sure that

all gas shutoff valves are open.

Once ignition is established, a gas pressure test should be taken at the gas valve pressure tap of each dryer to assure that the water column pressure is correct and consistent.

Note

The water column pressure requirements

(measured at the gas valve pressure tap)…

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.

Steam Models

Check to ensure that the steam damper is functioning properly.

The steam damper should not “slam” (open or closed) when it reaches the end of (piston) travel. Additionally, the steam damper should not bind and/or stop during travel. If either of these conditions occur, the flow control must be adjusted. Refer to the bottom illustration on the previous page for air adjustment instructions.

Make a complete operational check of all safety-related circuits (i.e., lint drawer switch and sail switch on gas models).

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 79 lb (35.83 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 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 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 one complete cycle to assure 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 computer has been preprogrammed by the factory with the most commonly used parameter (program) selections. If computer program changes are required, refer to the computer programming manual, which was shipped with the dryer.

Compressed Air Requirements _______

The dryer requires an external supply of compressed air (2.50 cfh at 80 psi [0.07 cmh 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 impellor/fan (squirrel cage).

Clean lint accumulation from the lint chamber, thermostat, and microprocessor temperature sensor (sensor bracket) area.

Warning

To avoid hazard of electrical shock, discontinue

electrical power supply to the dryer.

Steam Dryers

Clean the steam coil fins. Compressed air and a vacuum cleaner with brush attachment are suggested.

Note

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

Remove lint from around tumbler, drive motors, and surrounding areas. Remove lint from the gas valve burner area with a dusting brush or vacuum cleaner attachment.

Remove lint accumulation from inside the control box and at rear area behind the control box.

6 Months

Inspect and remove lint accumulation in customer furnished exhaust ductwork system and from dryer’s internal exhaust ducting.

Note

The accumulation of lint in the exhaust ductwork

can create a potential fire hazard. Do not obstruct the flow of combustion and ventilation air.

Check customer furnished back draft dampers in the exhaust ductwork. Inspect and remove any lint accumulation, which can cause the damper to bind or stick.

A back draft damper that is sticking partially closed can result in slow drying and shut down of the 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, (bearing setscrews), grounding connections, and nonpermanent gas connections (i.e., 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 (i.e., door switch, lint drawer switch, sail switch, burner and hi-limit thermostat).

Lubrication

The drive shaft bearings and idler shaft bearings should be lubricated every 3 months. Use a #2 grease or its equivalent. Lubrication is necessary.

The motor bearings and under normal/most conditions the tumbler bearing are permanently lubricated. It is physically possible to relubricate the tumbler bearing if you choose to do so even though this practice may not be necessary. Use Industrial Chevron ball or roller bearing SRI grease NLGI2 or its equivalent, which has a broad operating temperature range of -22° F (-30° C) to 350° F (177° C).

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 keypad 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.

Check all V-belts for tightness and wear . Retighten, realign, or replace V-belt if required.

Note

Replace in matched sets (both belts).

Warning

Discontinue power to dryer before attempting to

reset hi-limit.

Data Label Information _______________

Procedure for Functional Check of Replacement Components ________

For Heat Control Module Ignition Circuit For Models with Johnson Controls

DSI Module (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 “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” (L.E.D. flashes).

A steady L.E.D. indicator indicates normal operation. No L.E.D. indicator indicates a power or an internal failure

has occurred.

When contacting JLA, certain information is required to ensure proper service/parts information from JLA. This information is on the data label that is affixed to the rear upper left back area of the dryer, which can be viewed either through the openings in the dryer’s back panel/guard, or by removing this back panel/guard. When contacting JLA, 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. Manufacturing Code Number – The number issued by the manufacturer, which describes all possible options on your particular model.

4. Type of Heat – This describes the type of heat for your particular dryer , gas (either natural gas or L.P. gas), electric, or steam.

5. Heat Input (For Gas Dryers) – This describes the heat input in British thermal units per hour (Btu/hr).

6. Orifice Size (For Gas Dryers) – Gives the number drill size used.

7. Electric Service – This describes the electric service for your particular model.

8. Gas Manifold Pressure (For Gas Dryers) – This describes the manifold pressure taken at the gas valve tap.

For Models with HSI Module

Start the drying cycle. The HSI will turn on, and after approximately 4-seconds the

ignitor will shut off and the gas valve will be energized. Ignition (flame) should now be established.

With the burner flame on, remove the flame sensor wire from the S2 terminal of the HSI module. The burner flame must shut off immediately.

Stop the drying cycle, with the flame sensor wire still removed, restart the drying cycle.

The HSI will turn on, and after a few seconds later the gas valve will be energized and the HSI will shut off. Ignition (flame) should be evident for approximately 7-seconds and then shut off.

The HSI module will attempt to light burner only “once.” If flame is not reestablished the HSI module will lockout and the “red” indicator light will flash continuously.

Functional check of the HSI module is complete. Replace the flame sensor wire from the S2 terminal to the

HSI module.

Water Information ____________________

Before You Start! Check Local Codes And Permits

Call your local water company or the proper municipal authority for information regarding local codes.

Important

It is your responsibility to have all plumbing

connections made by a qualified professional to assure that the plumbing installation is adequate and conforms to local, state, and federal regulations or codes.

Installation Requirements

The connection point to the electric water solenoid valve is a 1/2” M.P.T., the S.A.F.E. system must be supplied with a minimum water pipe size of 1/2-inch and be provided with 40 psi +/- 20 psi (2.75 bar +/- 1.37 bar) of pressure. For use of optional manual bypass, a second source with the same piping and pressure requirements is required.

Flexible 1/2 feeds must be provided to avoid damage to electric water solenoid valve by vibration.

Important

Flexible supply line/coupling must be used.

Solenoid valve failure due to hard plumbing connections will void warranty.

If the rear area of the dryer, or the water supply is located in an area where it will be exposed to cold/freezing temperatures, provisions must be made to protect these water lines from freezing.

113375-6 Telephone 01422 822282 21

Page 22

Water Connections

The water connection is made to the 1/2” M.P.T. bushing of the electric water solenoid valve, located at the rear upper left area of the dryer. The water solenoid valve has a 3/8” M.P.T. connection and a 1/2” bushing is supplied to provide the minimum 1/2” supply (feed) line. Flexible supply line/coupling must be used in effort to avoid damage to electric water solenoid valve.

Important

Flexible supply line/coupling must be used. Solenoid

valve failure due to hard plumbing connections will void warranty. It is recommended that a filter or strainer be installed in the water supply line.

Typical Water Supply …

Optional Manual Bypass

Provisions are made in the dryer’s S.A.F.E. system for the installation of an optional manual bypass. Depending on the model dryer, the connections for the manual bypass are made at the “T” or “three way” fitting, located in the outlet supply side of the water solenoid valve. The use and connections of this manual bypass are at the option or discretion of the owner.

The water connection for the manual bypass is made to the “T” or “three way” fitting, which has a 3/8” F.P.T. and a coupling must be used to provide the minimum 1/2” supply (feed) line.

If the rear area of the dryer, or the water supply is located in an area where it will be exposed to cold/ freezing temperatures, provisions must be made to protect these water lines from freezing.

The manual ball cock shutoff valve must be located outside of the dryer at a distance from the dryer where it is easily accessible.

Electrical Requirements

No independent external power source or supply connection is necessary. The 24 volt power to operate the S.A.F.E. system is accomplished internally in the dryer (from the dryer controls).

Warning

Electrical power must be provided to the

dryer at all times. If the main electrical power supply to the dryer is disconnected, the S.A.F.E. system is inoperative!

S.A.F.E. System Theory of Operation

20-seconds after the heat turns off, the Phase 7 control monitors the S.A.F.E. system probe located in the top of the tumbler chamber and records the minimum temperature. If the minimum recorded temperature is no less than 120° F (48° C) and the control detects a 35° rise in temperature, this will be the trip point and the S.A.F.E. system routine will activate.

While a drying cycle is in process and the heat is on, the Phase 7 control monitors the exhaust temperature transducer. If the drying cycle temperature set point is set greater than 160° F (71° C) and the control detects an exhaust temperature rise 25° F greater than set point, this will be the trip point and the S.A.F.E. system routine will activate.

Once the S.A.F.E. system routine is activated, water will be injected into the tumbler chamber. Anytime water is being injected into the tumbler; the tumbler drive will turn the load for 1-second every 15-seconds. This process will continue for a minimum of 2 minutes. After 2 minutes has elapsed, the control will check if the temperature remained above trip point, if so water will remain on. The control will continue to check if temperature is above trip point every 30-seconds. If the water has been on for a constant 10 minutes, the water will be turned off regardless of the temperature. If the temperature has dropped below trip point, the control will turn off the water prior to 10 minutes.

System Reset

After the microprocessor determines that the situation is under control and shuts the water being injected into the tumbler off, the microprocessor display will read “SENSOR ACTIVATED FIRE EXTINGUISHING ACTIV ATED”, and the horn/tone will sound until reset manually.

To reset the microprocessor and S.A.F.E. system, press the red key on the keypad.
