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-LATESTEDITION, or in Canada, the installation must conform to applicable Canada Standards: Canadian Electrical Codes Parts 1 & 2 CSAC22.1-1990or 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-metalconnection 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.

Single-Phase(1ø)

Wiring Connections/Hookup

The electrical input connections are made into the rear service box located at the upper right area of the dryer. The ground connection is made to the copper lug, also provided in this box. To gain access, the service box cover must be removed.

Gas Information ______________________

It is your responsibility to have all plumbing connections, materials, and workmanship conform to local and state regulations or codes of the country of destination. In the absence of such codes, all plumbing connections, materials, and workmanship must conform to the applicable local requirements. In the USA this is the National Fuel Gas Code ANSI Z223.1-LATESTEDITION, or in Canada, the Canadian Installation CodesCAN/CGA-B149.1-M91(Natural Gas) orCAN/CGAB149.2-M91(L.P. Gas) or LATEST EDITION.

In Australia, the fuel gas code is AS 5601/AG 601, local authority, gas, electricity, and any other relevant statutory regulations.

It is important that gas pressure regulators meet applicable pressure requirements, and that gas meters be rated for the total amount of all the appliance Btu being supplied.

Important: Failure to comply with these codes or ordinances, and/or the requirements stipulated in this manual, can result in personal injury and improper operation of the dryer.

For ease of service, the individual gas supply line of each dryer must have its own manual shutoff valve.

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) for non-CEdryers or 50 mb for CE dryers.

Failure to isolate or disconnect the dryer from supply as noted can cause irreparable damage to the gas valve, voiding the warranty.

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) for nonCE dryers or 50 mb for CE dryers.

Warning

!Fire or explosion could result due to failure of isolating or disconnecting the gas supply as

noted.

Note: Undersized gas piping will result in ignition problems, slow drying, increased use of energy, and can create a safety hazard.

The dryer must be connected to the type of heat/gas indicated on the data label and pressure must be confirmed. If this information does not agree with the type of gas available, do not operate the dryer. Contact the reseller who sold the dryer or contact the manufacturer.

The input ratings shown on the data label are for elevations up to 2,000 feet (610 meters), unless elevation requirements of over 2,000 feet (610 meters) were specified at the time the dryer order was placed with the factory. The adjustment or conversion of dryers in the field for elevations over 2,000 feet (610 meters) is made by changing each burner orifice. If this conversion is necessary, contact the reseller who sold the dryer or contact the manufacturer.

Important: If connection to this appliance is made with a flexible hose, it must be suitable for the appliance category in accordance with national installation regulations of the country of destination, and if in doubt the installer must contact the supplier. The manufacturer of this appliance does not recommend the use of flexible gas supply line/ hose. An external gas supply shutoff must be provided.

CE and Australian Dryers

There is an N.P.T. to B.S.P.T. adaptor included with each dryer, which must be installed to the gas inlet. The adaptor is shipped in the tumbler.

Important: Pipe joint compounds that resist the action of natural, propane, and butane gases must be used.

Piping/Connections

Inlet Connection – 1/2” M.N.P.T.

CE and Australian dryer connections will be B.S.P.T., all others will be N.P.T.

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-operatedappliances 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.

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. Anin-linepressure 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.

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!!!

Gas Pressure Testing _________________

For proper operation, the gas pressure must be correct, consistent and maintained at the gas pressure rates shown on page 14. 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 millibar. When it is filled with water and pressure is applied, the water in the tube rises, showing the exact gas pressure.

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.

60 Hz dryers: Install pressure tap and attach manometer. 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 14.

Once test is complete, turn gas cock to “OFF” position. Remove manometer. Tighten screw inside the pressure tap or install plug.

Turn gas cock to “ON” position and check for leaks with soap solution with main burner “ON.”

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-drippedsteam main. If the supplyrun-outto 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.

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 272 lb (123.37 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”-11.5NH 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: The3/4”-11.5NH 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.

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.

Electrical Requirements

No independent external power source or supply connection is necessary. The 24-voltpower to operate the fire suppression system is accomplished internally in the dryer (from the dryer controls).

16

American Dryer Corp.

113615-1

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-LimitThermostats

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.

Preoperational Instructions __________

Important: For more detailed information regarding the microprocessor controller (computer), refer to the microprocessor user’s manual included with the dryer.

Before any dryer leaves the factory test area, a warranty card is placed on the inside 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 Warranty Department or the Service Department at +1 (508) 678-9000.

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 commercial warranty covering your particular dryer(s), contact the 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 the factory by contacting the Warranty Department at +1 (508) 678-9000.

Note: Whenever contacting the factory 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.

Returning Warranty Parts

All dryer or parts warranty claims or inquiries should be addressed to the Warranty Parts Department. To expedite processing, the following procedures must be followed:

No parts are to be returned without prior written authorization R.M.A. from the factory.

Note: An R.M.A. is valid for only 30 days from date of issue.

The R.M.A. issued by the factory, as well as any other correspondence pertaining to the returned part(s), must be included inside the package with the failed merchandise.

Each part must be tagged with the following information:

Model number and serial number of the dryer from which part was removed.

Nature of failure (be specific). Date of dryer installation. Date of part failure.

Specify whether the part(s) being returned is for a credit, replacement, or a refund.

Note: If a part is marked for a credit or a refund, the invoice number covering the purchase of the replacement part must be provided.

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

!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 the drawer out loosen the torx screws on the sides of the rails. This allows the metal clips to rotate and allow the drawer to be fully removed. Reverse the above process for installation.

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.

Warning

!To avoid the hazard of electrical shock, discontinue electrical supply to the dryer.

Steam Dryers

Clean the steam coil fins. It is suggested that compressed air and a vacuum cleaner with brush attachment be used.

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 airconditioning 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.

Note: To prevent damage, avoid cleaning and/or touchingignitor/flame-probeassembly.

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.

7 Days After Installation

and Every 12 Months Thereafter

A competent professional should 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-limitthermostats).
