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-B149.2M91 (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.

The dryer must not be installed or stored in an area where it will be exposed to water and/or weather.

Provisions for adequate air supply must be provided as noted in this manual (refer to Fresh Air Supply Requirements section).

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).

Unpacking/Setting Up _________________

Remove protective shipping material (i.e., plastic wrap and optional shipping box) from the dryer.

Important

Dryer must be transported and handled in an

!

upright position at all times.

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 2 bolts securing the base of the dryer to the wooden skid. One is located at the center rear and the other is at the center front.

With the skid removed, use caution and assure all four leveling legs are fully retracted, if the dryer is to be slid into its final position.

Leveling Dryer

The dryer is equipped with 4 leveling legs, 1 at each corner of the base. For optimum performance the dryer should be level front-to-back and side-to-side.

Dryer Enclosure Requirements _______

Bulkheads and partitions should be made of noncombustible material.

Note

Allowances must be made for opening the control

!

door.

Important

The dryer should be located where a minimum

!

amount of exhaust ducting will be necessary.

The dryer must be installed with adequate clearance for air openings into the combustion chamber.

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.

Important

The dryer must be installed in a location/

!

environment, which the ambient temperature

remains between 40° F (4.44° C) and 130° F (54.44° C).

10 JLA Limited 113428- 9

A The requirement to allow the door to open completely for

the T20 stack is 30-inches (76.2 cm), and for the T30 stack is 33-inches (83.8 cm).

B A minimum overhead clearance of 6-inches (15.24 cm) is

required.

C Dryer should be positioned a minimum of 12-inches (30.48

cm) away from the nearest obstruction. 24-inches (60.96 cm) is recommended for ease of installation, maintenance,

and service. D 1/16” (1.5875 mm) minimum is required. E Flooring should be level or below dryer cabinet for ease

of removing panels during maintenance. F Dryers may be positioned sidewall to sidewall, however a

1/16” (1.5875 mm) minimum allowance must be made for

the opening and closing of the control door, along with

the removal of panels during maintenance.

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 of 110 inch (710 cm2) is required for each T30 stack and 80 inch2 (516

2

) for each T20 stack. (Based on 1 inch2 [6.5 cm2] per 1,000

cm Btu [252 kcal].)

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.

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.

Caution

This dryer produces combustible lint and must be

!

2

Improperly sized or installed exhaust ductwork can create a

potential fire hazard.

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. There should be a minimum 6-inch (15.24 cm)

clearance between the back guard and the first bend in the

ductwork for ease of servicing. Single or independent dryer

venting is recommended. It is suggested that the use of 90°

turns be avoided; use 30° and/or 45° bends instead. The radius

of the elbows should preferably be 1-1/2 times the diameter of

the duct. All ductwork should be smooth inside with no

projections from sheet metal screws or other obstructions,

which will collect lint. When adding ducts, overlap the duct

being connected. All ductwork joints must be taped to prevent

moisture and lint from escaping into the building. Back draft

dampers must be installed in all commonly ducted systems.

Inspection doors should be installed at strategic points in the

exhaust ductwork for periodic inspection and cleaning of lint

from the ductwork.

exhausted to the outdoors.

A = 14-inches (35.56 cm) B = 16-inches (40.64 cm)

EXAMPLE: For a bank of 4 T30 stack dryers, 2 unrestricted openings measuring 14-inches by 16-inches (35.56 cm by

40.64 cm) are acceptable. To compensate for the use of registers or louvers used over

the openings, this area must be increased by approximately 33%. Make-up air openings should not be located in an area directly near where exhaust vents exit the building.

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

Important

Make-up air must be 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.

Important

It is recommended that exhaust or booster fans not

!

be used in the exhaust ductwork system.

Exhaust back pressure measured by a manometer/ magnehelic in the exhaust duct must be no less than 0 and must not exceed 0.6 in WC (1.48 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.

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.”

The ductwork for this appliance must be suitable for the appliance category in accordance with national installation regulations of the country of destination.

113428 -9 Telephone 01422 822282 11

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 (refer to the diagram).

Important

Do not use screens, louvers, or caps on the outside

!

opening of the exhaust ductwork.

Single Dryer Venting

Important

For extended ductwork runs, the cross-sectional

!

area of the ductwork can only be increased to an extent. When the ductwork approaches the maximum limits as noted in this manual, a professional HVAC firm should be consulted for proper venting information.

The length of the ductwork from the dryer to the outside exhaust outlet, must not exceed 12 feet (3.66 meters) for the T30 stack and 20 feet (6.10 meters) for the T20 stack. The minimum

diameter of this ductwork must be at least 8-inches (20.32 cm) even though the dryer exhaust duct connection is smaller. Including tumbler/dryer elbow connections or elbows

used for outside protection from the weather, no more than 4 90° elbows should be used in the exhaust duct run. If more than the equivalent of 4 90° elbows are used, the crosssectional area of the ductwork must be increased.

Multiple Dryer (Common) Venting

Important

For extended ductwork runs, the cross-sectional

!

area of the ductwork can only be increased to an extent. When the ductwork approaches the maximum limits as noted in this manual, a professional HVAC firm should be consulted for proper venting information.

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 45º in the direction of airflow. The main duct should be tapered, with the diameter increasing before each individual duct is added. The minimum diameter of the individual ductwork must be at least 8-inches (20.32 cm).

A = T20 Stack - 20 feet (6.10 meters)

T30 Stack - 12 feet (3.66 meters)

B = 8-inches (20.32 cm)

Important

No more than 4 dryers should be connected to 1

!

main common duct.

A ground (earth) connection must be provided and installed in accordance with local, state, and national regulations or codes of the country of origin. In the absence of these codes, grounding must conform to applicable requirements of the National Electrical Code ANSI/NFPA NO. 70-LATEST EDITION, or in Canada, the installation must conform to applicable Canada Standards: Canadian Electrical Codes Parts 1 & 2 CSA C22.1-1990 or LATEST EDITION. The ground connection may be to a proven earth ground at the location service panel.

For added personal safety, when possible, it is suggested that a separate ground wire (size per local codes) be connected from the ground connection of the dryer to a grounded cold water pipe. Do not ground to a gas pipe or hot water pipe. The grounded cold water pipe must have metal-to-metal connection all the way to the electrical ground. If there are any nonmetallic interruptions, such as, a meter, pump, plastic, rubber, or other insulating connectors, they must be jumped out with a wire (size per local codes) and securely clamped to bare metal at both ends.

Important

For personal safety and proper operation, the dryer

!

must be grounded.

Provisions are made for ground connection in each dryer at the electrical service connection area.

Electrical Connections

A wiring diagram is located behind the control panel for connection data.

If local codes permit, power to the dryer can be made by the use of a flexible UL listed power cord/pigtail (wire size must conform to rating of dryer), or the dryer can be hard wired directly to the service breaker panel. In both cases, a strain relief must be installed where the wiring enters the dryer.

For CE Models Only

The means for disconnection from the supply must be incorporated into wiring having a minimum contact separation of 3.0 mm in all poles.

Piping/Connections

The dryer is provided with two 3/8” N.P.T. (3/8” B.S.P.T. for CE dryers) inlet pipe connections (1 for each tumbler) at the rear of the dryer. If a separate feed is provided for each tumbler from the main supply line (header), then a 1/2” (12.7 mm) line connection is sufficient. However, if the top and bottom tumbler connections are connected together, the supply from the header must be increased to 3/4-inch (19.05 mm). There should be a minimum 6-inch (15.24 cm) clearance between the back guard and the first bend in the gas piping for ease of servicing. It is recommended that a gas shutoff valve be provided to the gas supply line of each dryer for ease in servicing.

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.

Important

Pipe joint compounds that resist the action of

!

natural, L.P., and butane gases must be used.

Test all connections for leaks by brushing on a soapy water solution (liquid detergent works well).

Warning

!

Never test for leaks with a flame!!!

NOTES ____________________________________

___________________________________________

TYPICAL NATURAL GAS INSTALLATION

TYPICAL L.P. GAS INSTALLATION

___________________________________________

Consistent gas pressure is essential at all gas connections. It is recommended that a 3/4-inch (19.05 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 13.0 in WC (32.34 mb) pressure.

A plugged tap, accessible for a pressure gauge connection, must be installed in the main gas supply line immediately upstream of the dryers.

Converting from One Family of Gas to Another______________________

Warning (CE Dryers)

This appliance must only be operated with the gas

!

type indicated on the dryer’s data plate. If the appliance is converted (gas type changed), a data plate amendment must be obtained from JLA Limited (dryer’s serial number is required to purchase a conversion kit).

Important

Any burner changes or conversions must be made

!

by a qualified professional.

The dryers manufactured for Belgium, Luxemburg, Greece, Estonia, Slovak Republic, Iceland, Malta, Poland and Cyprus cannot be converted from one family of gas to another.

Conversion from Natural Gas to Propane or Butane Gas

The following conversion allows the dryer to be operated with either propane, butane, or LPG. The use of gas valve kit (P/N

140414) disables the internal regulator of the gas valve. Therefore, the gas supply is ungoverned and an external regulator must be provided at the source of the supply (example L.P. tank) or the gas supply line to the dryer. The L.P. kit supplied will depend on the country the dryer is installed in.

Important

Use extreme care when removing and replacing

!

orifice (injector). This orifice (injector) is made of

brass, which is easily damaged.

Reinstall the burner tube onto the burner base. Use a flat screwdriver to remove the regulator vent cap.

• For unregulated L.P. gas (most countries): install blocking pin (P/N 140414).

• For regulated L.P. gas (some countries): remove the white plastic regulator adjustment screw (under vent cap). Remove spring under screw and replace with spring from kit (P/N 140416). Replace regulator adjustment screw.

Install the gas train back into the dryer gas train enclosure. Be sure the tab at the rear of the gas train engages into the mounting slot.

Connect the union and the 3 electrical plugs. Repeat these steps for the other burner. Affix L.P. Conversion Label (P/N 114515) to the dryer’s data

label. Complete L.P. Kit Conversion Confirmation Label (P/N 114083)

and affix this label as close as possible to the dryer’s existing dryer rating (data) label/plate.

!

both top and bottom tumblers.

Reinstall the burner tube onto the burner base. Select from the following 3 options, the conversion to be

performed:

• Converting from unregulated L.P. to regulated natural gas: use a flat screwdriver to remove the cap with blocking pin and install the regulator vent cap from the kit (P/N 140415).

• Converting from unregulated L.P. to unregulated natural gas: no change to the regulator is required.

• Converting from regulated L.P. to regulated natural gas: remove the white plastic regulator adjustment screw (under vent cape). Remove spring under screw and replace with spring from kit (P/N 140415). Replace regulator adjustment screw.

Install the gas train back into the dryer gas train enclosure. Be sure the tab at the rear of the gas train engages into the mounting slot.

Connect the union and the 3 electrical plugs. Repeat these steps for the other burner. Open all shutoff valves, reconnect electrical power to the dryer,

and test for leaks. Operate the dryer through 1 complete cycle to ensure proper

operation. With dryer operating, check the manifold (burner) pressure at

the tap on the gas valve to ensure proper operating pressure (refer to chart on page 17).

Gas Pressure Adjustment

Disconnect electrical power to the dryer.

Open the panels located just below each loading door. Locate the gas train and disconnect the union, 3 electrical

plugs, and the gas train mounting screws from the burner. Carefully slide the gas train out of the gas train enclosure. (The carbon ignitor located at the far end of the gas train is very fragile.)

Remove 2 burner tube mounting screws and remove burner tube in order to gain access to the orifice.

Using a 3/8” wrench or socket, remove the existing orifice and replace it with an orifice from the kit.

Important

Use extreme care when removing and replacing

!

orifice (injector). This orifice (injector) is made of

brass, which is easily damaged.

Important

The following procedures must be performed on

!

both top and bottom tumblers.

To adjust gas valve’s internal regulator, remove the regulator vent cap with the regulator adjustment tool, which is located on the back guard between the gas inlet and exhaust outlet (refer to the illustration on next page for proper use of adjustment tool). Be sure to use one of the wide ends of the adjustment tool for removal of the vent cap. Once vent cap is removed, the narrow end of the adjustment tool can be used to turn the plastic adjustment screw in the valve. Turn the screw clockwise to raise pressure and counterclockwise to lower pressure.

Gas (burner) pressures are measured with the burner in operation for all burner adjustment conditions. Therefore once the necessary adjustments have been made, the dryer must be operated in a heating cycle to verify that the pressure is correct. If it is not correct, you must discontinue the power to the unit and make further adjustments. Repeat these steps as many times as necessary to achieve the correct burner pressure. Once the adjustment of the valve is complete, the vent cap must be replaced and sealed with, for example, paint to prevent maladjustment by the user.

Warning (CE Dryers)

This appliance must only be

!

operated with the gas type indicated on the dryer’s data plate. If the appliance is converted (gas type changed), a data plate amendment must be obtained from JLA Limited.

Conversions done improperly can result in a fire or explosion!

Gas Pressure Testing ______

For proper operation, the gas pressure must be correct, consistent and maintained at the gas pressure rates shown on page 17. Provisions are made at the gas valve for taking gas pressure readings.

There are 2 types of devices used to measure gas pressure. They are the spring/mechanical type gauge and the manometer. The use of the spring/mechanical type gauge is not recommended because they are very easily damaged and are not always accurate. The preferred type of gauge is the manometer because it is a simple device to use and is highly accurate. A manometer is simply a glass or transparent plastic tube with a scale graduated in inches or millibars. When it is filled with water and pressure is applied, the water in the tube rises, showing the exact gas pressure.

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, state, and country 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 25 feet (7.6 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.

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

Coil failure due to improper pH level will void the warranty.

!

Gas Pressure Test Procedure

Turn gas cock in gas supply line to “OFF” position.

50 Hz dryers: Back out miniature screw inside pressure tap and attach manometer (refer to the illustration on page 19).

60 Hz dryers: Install pressure tap and attach manometer (refer to the illustration on page

19). Turn gas cock to “ON” position. Start the dryer in Heat Mode and wait for

ignition. Gas manifold pressure should be as shown on page 17.

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.

Important

Steam coil failure due to water hammer by wet

!

steam will void the warranty.

The presence of 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.

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 minimum capacity of 100 lb (45.35 kg) of condensate per hour at 125 psi (8.62 bar) is needed for each unit. (Based on 2 times the steam consumption per hour.)

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. Install a bypass trap in any low point to eliminate wet steam.

Important

Flexible hoses/couplings must be used. Coil failure

!

due to hard plumbing connections will void the

warranty.

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 ensure that the plumbing installation is adequate and conforms to local, state, and federal regulations or codes.

It is the installer’s or owner’s responsibility to see that the required water pressure, pipe size, or connections are provided. The manufacturer assumes no responsibility if the fire suppression system is not connected, installed, or maintained properly.

Installation Water Supply

The fire suppression system must be supplied with a minimum water pipe size of 1/2-inch (12.7 mm) and be provided with 40 psi +/- 20 psi (2.75 bar +/- 1.37 bar) of pressure.

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.

Warning

If the water in the supply line or water solenoid

!

valve freezes, the fire suppression system will be

inoperative!!

Water Connections

The water connection is made to the 3/4”-11.5 NH hose adaptor, which is shipped in the tumbler and must be installed to the 1/2” N.P.T. water connection, located at the upper rear of the dryer. A flexible supply line/coupling must be used in an effort to avoid damaging the electric water solenoid valve.

Note

The 3/4”-11.5 NH is a standard hose coupling

!

screw thread. It is not to be confused with 3/4” N.P.T. The sealing of an NH connection is made with a washer opposed to the mating threads of an N.P.T. assembly. The 2 thread designs are not compatible.

It is recommended that a filter or strainer be installed in the water supply line.

22 JLA Limited 113428- 9

Important

Flexible supply line/coupling must be used.

!

Solenoid valve failure due to hard plumbing

connections will void warranty.

The dryer is to be connected to the water mains using a new hose set and the old hose set should not be reused.

Optional Manual Bypass

Provisions are made in the dryer’s fire suppression system for the installation of an optional manual bypass. The connections for the manual bypass are made at the “cross” or “four way” fitting located in the outlet supply side of the water solenoid valve. The manual ball cock shutoff valve must be located outside of the dryer at a distance from the dryer where it is easily accessible. The use and connection of this manual bypass is at the option or discretion of the owner.

The water connection for the manual bypass is made to the “cross” or “four way” fitting, which has a 3/8” F.N.P.T. and a coupling must be used to provide the minimum 1/2-inch (12.7 mm) supply (feed) line.

Electrical Requirements

No independent external power source or supply connection is necessary. The 24-volt power to operate the fire suppression 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 fire suppression system is inoperative!!

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 data label. In the case of 208 VAC or 240 VAC, the supply voltage must match the electric service exactly.

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

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

• Be sure all back panels (guards) and electric box covers are in place.

• Be sure the service doors are closed and securely in place.

• Be sure the lint door/drawer is securely in place.

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

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

• Check that the vent is connected to the dryer and is exhausted to the outdoors.

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

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. Refer to the Operating Instructions for starting your particular

model dryer.

Gas Dryers

Open all shutoff valves. 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.

A gas pressure test should be taken at the gas valve pressure tap of each dryer to ensure that the water column pressure is correct and consistent.

Note

Water column pressure requirements (measured at

!

the pressure tap of the gas valve body) must be

verified.

Important

In most cases 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.

Electrical Dryers

Check to ensure that electric oven/contactor assembly is activating.

Safety Related Circuits

Make a complete operational check of all safety related circuits:

• Door Switch(es)

• Hi-Limit Thermostats

• Sail Switch

Make a complete operational check of all operating controls.

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.

Microprocessor Programs/Selections

Each microprocessor controller (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.

___________________________________________

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 airflow. The accumulation of lint can restrict this airflow. If the guidelines in this section are met, the dryer will provide many years of efficient, trouble free, and most importantly, safe operation.

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

Remove lint from gas valve burner area with a dusting brush or vacuum cleaner attachment.

Clean any lint accumulation in and around the motor(s) casing opening.

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 6 to 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.

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 door/drawer is located just below the loading door of the dryer. Open the lint door/drawer, brush the lint off the lint screen, and remove the lint. Inspect lint screen and replace if torn.

Note

To remove the lint drawer from the dryer, pull

!

drawer out approximately halfway. Press the lint

door/drawer stop downward and pull the drawer out.

Important

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 area.

Note

To prevent damage, avoid cleaning and/or touching

!

ignitor/flame-probe assembly.

Every 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 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 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 12 Months Thereafter

Inspect bolts, nuts, screws, setscrews, grounding connections and nonpermanent gas connections (unions, shutoff valves, and orifices). Belts should be examined. Cracked or seriously frayed belts should be replaced. Complete an operational check of controls and valves. Complete an operational check of all safety devices (lint door/drawer switch, door switches, sail switch, and hi-limit thermostats).

Warning

To avoid the hazard of electrical shock, discontinue

!

electrical supply to the dryer.
