IMPORTANT INFORMATION

A. RECEIVING AND HANDLING

The dryer is shipped in a protective stretch wrap cover with protective cardboard comers and
top cover (or optional box) as a means of preventing damage in transit. Upon delivery, the dryer and
/ or protective packaging, and wooden skid should be visually inspected for shipping damage. If
any damage whatsoever is noticed, inspect further before delivering carrier leaves.

Dryers damaged in shipment:

1. All dryers should be inspected upon receipt and before they are signed for.

2. If there is suspected damage or actual damage, the trucker’s receipt should be so noted.

3. If the dryer is damaged beyond repair, it should be refused. Those dryers which were not

damaged in a damaged shipment should be accepted, but the number received and number
refused must be noted on the receipt.

4. If you determine that the dryer was damaged after the trucker has left your location, you

should call the delivering carrier’s freight terminal immediately and file a claim. The freight
company considers this concealed damage. This type of freight claim is very difficult to get
paid and becomes extremely difficult when more than a day or two passes after the freight was
delivered. It is your responsibility to file freight claims. Dryers / parts damaged in transit

3-1

INSTALLATION PROCEDURES

B. DRYER ENCLOSURE REQUIREMENTS

Even though a 12-inch clearance is acceptable, it is recommended that the rear of the dryer
be positioned approximately two (2) feet (24-inches) from 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
and must not extend more than 4-inches to the rear of the dryer front. The bulkhead facing must not
be closed in all the way to the top of the dryer. A 2-inch clearance is required.

NOTE: Bulkhead facing should not be installed until after dryer is in place. Ceiling area must be
located a minimum of 12-inches above the top of the dryer.
IMPORTANT: Even though a minimum of only 12-inches is required, 18-inches or more is
suggested, for steam dryers and especially in cases where sprinkler heads are over
the dryers.
NOTE: When fire sprinkler systems are located above the dryers, a minimum of 18-inches above
the dryer console (module) is suggested. Dryers may be positioned side wall to side wall

INSTALLATION PROCEDURES

C. FRESH AIR SUPPLY

When the dryer is operating, it draws in room air, heats it, passes this air through the basket
(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.

Air supply (make-up air) must be given careful consideration to assure proper performance
of each dryer. An unrestricted source of air is necessary for each dryer. An air flow of 2,150 cfm
(cubic feet per minute) must be supplied to each gas dryer and electric dryer with a 72 Kw oven,
2,500 cfm to each electric dryer with a 80 Kw oven, and 2,750 cfm for each steam dryer. As a
general rule, an unrestricted air entrance from the outdoors (atmosphere) of a minimum of three (3)
square feet is required for each gas dryer and 72 Kw electric dryer and a minimum of five (5)
square feet for each steam dryer and 80 Kw electric dryer.

To compensate for the use of registers or louvers used over the openings, this make-up air
area must be increased by approximately thirty-three (33) 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 six (6) gas dryers, two (2) openings measuring 3 feet by 3 feet (18
square feet) is acceptable.

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

INSTALLATION PROCEDURES

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 motors and other dryer components.

NOTE: Component failure due to dry cleaning solvent fumes VOIDS THE WARRANTY.

D. EXHAUST REQUIREMENTS

1. General Exhaust Duct Work Information

Exhaust duct work should be designed and installed by a competent technician. Improperly
sized duct work will create excessive back pressure which will result in slow drying, increased use
of energy , and shutdown of the burner by the airflow (sail) switch, burner hi-limit, or lint chamber
hi-heat protector thermostat.

CAUTION: DRYER MUST BE EXHAUSTED TO THE OUTDOORS.
CAUTION: IMPROPERLY SIZED
CREA

TE POTENTIAL FIRE HAZARD.

OR INSTALLED EXHAUST DUCT WORK CAN

NOTE: When a dryer is exhausted separately, it is recommended that a back draft damper be

installed.
NOTE: When dryers are exhausted into a multiple (common) exhaust line, each dryer must be
supplied with a back draft damper.

The duct work should be laid out in such a way that the duct work 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 duct work from the dryer to the outside
exhaust outlet should not exceed twenty (20) feet. In the case of multiple (common) dryer venting,
the distance from the last dryer to the outside exhaust outlet should not exceed twenty (20) feet.
The shape of the duct work is not critical so long as the minimum cross section area is provided. It
is suggested that the use of 90° turns in ducting be avoided;

use 30° and/ or 45° angles instead. The
radius of the elbows should preferably be 1-1/2 times the diameter of the duct. Excluding
basket/dryer elbow connections or elbows used for outside protection from the weather, no more
than two (2) elbows should be used in the exhaust duct run. If more than two (2) elbows are used,
the cross section area of the duct work must be increased in proportion to number of elbows added.

ALL

duct work 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

duct work 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 duct work for periodic inspection and clean-out of lint from the duct work.

IMPORTANT: Exhaust back pressure measured by a manometer at each basket exhaust duct area
should not exceed 0.3 inches of water column.
NOTE: Where the exhaust duct work passes through a wall, ceiling, or roof made of combustible
materials, the opening must be 2-inches larger (all the way around) than the duct. The duct
must be centered within this opening

Outside Duct Work Protection

To protect the outside end of horizontal duct work from the weather, a 90° elbow bent
downward should be installed where the exhaust exits the building. If the exhaust duct work 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.

3-4

INSTALLATION PROCEDURES

IMPORTANT: DO NOT use screens or caps on the outside of opening of exhaust duct work.

Figure.3-3 Outside Duct Work Protection

2. 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 duct work travels as directly as possible to
the outdoors with as few turns as possible. It is suggested that the use of 90° turns in ducting be
avoided; use 30° and/ or 45° angles instead. The shape of the exhaust duct work is not critical so
long as the minimum cross section area is provided.

IMPORTANT: Minimum duct size for a gas dryer or 72 Kw electric dryer is 18-inches for a round
duct or 16" x 16" for a square duct. The minimum duct size for a steam dryer
or 80 Kw electric dryer is 18-inches for a round duct or 16" x 16" for a
square duct. Duct size must not be reduced anywhere down stream of dryer.
IMPORTANT: Exhaust back pressure measured by a manometer at each basket (tumbler) exhaust
duct area should not exceed 0.3 inches of water column.

It is suggested that the duct work from each dryer (minimum 18-inches for a gas dryer or 72
Kw electric dryer and 18-inches for a steam dryer or 80 Kw electric dryer) not exceed twenty (20)
feet with no more than two (2) elbows (excluding dryer connections and outside exhaust outlets). If
the duct work exceeds twenty (20) feet or has numerous elbows, the cross section area of the duct
work must be increased in proportion to the length and number of elbows in it. In calculating duct
size, the cross section area of a square or rectangular duct must be increased by twenty (20) percent
for each additional twenty (20) feet. The diameter of a round exhaust duct should be increased ten
(10) percent for each additional fifteen (15) feet. Each 90° elbow is equivalent to an additional
thirty (30) feet, and each 45° elbow is equivalent to an additional fifteen (15) feet.

3-5

INSTALLATION PROCEDURES

Figure.3-4 Single Dryer Venting

IMPORTANT: For extended duct work runs, the cross section area of the duct work can only be

increased to an extent. Maximum proportional duct work runs cannot

exceed
twenty (20) feet more than the original limitations of twenty (20) feet with two (2)
elbows. When the duct work approaches the maximum limits as noted in this
manual, a professional heating venting air conditioning (HV AC) firm should be

consulted for proper venting information.

ALL

duct work 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

duct work 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 duct work for periodic inspection and clean-out of lint from the duct work.

NOTE: Where the exhaust duct passes through a wall, ceiling, or roof made of combustible
materials, the opening must be 2-inches larger (all the way around) than the duct. The duct

must be centered within this opening.

To protect the outside end of horizontal duct work from the weather, a 90° elbow bent
downward should be installed where the exhaust exits the building. If the exhaust duct work 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 nearest obstruction.

IMPORTANT: DO NOT use screens, louvers, or caps on the outside of opening of exhaust duct
work.

3-6

INSTALLATION PROCEDURES

3. 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 air flow and should be
spaced at least 48-3/8 inches apart. The main duct should be tapered, with the diameter increasing
before each individual 18-inch (minimum for gas dryers or 72 Kw electric dryers) or 18-inch
(minimum for steam dryers or 80 Kw electric dryers) duct is added.

IMPORTANT: The DP is not provided with a back draft damper. When exhausted into a multiple
(common) exhaust line, a back draft damper must be installed at each dryer duct.
IMPORTANT: No more than four (4) 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. These figures must be increased 10 square inches when rectangular main
ducting is used, and 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 twenty [20] feet) or has numerous elbows (more than two [2])
in it. In calculating duct work size, the cross section area of a square or rectangular duct must be
increased twenty (20) percent for each additional twenty (20) feet. The diameter of a round exhaust
must be increased ten (10) percent for each additional twenty (20) feet. Each 90° elbow is
equivalent to an additional thirty- (30) feet and each 45° elbow is equivalent to an additional fifteen
(15) feet.

IMPORTANT: For extended duct work runs, the cross section area of the duct work can only be
increased to an extent. Maximum proportional duct work runs cannot

exceed
twenty (20) feet more than the original limitations of twenty (20) feet with two (2)
elbows. When the duct work approaches the maximum limits as noted in this
manual, a professional HV AC firm should be consulted for proper venting
information.

IMPORTANT: Exhaust back pressure measured by a manometer at each dryer exhaust duct area
should not exceed 0.3 inches of water column.

The duct work 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

duct work 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 duct work for periodic inspection and clean-out of lint from the duct work.

NOTE: Where the exhaust passes through a wall, ceiling, or roof made of combustible materials,
the opening must be 2-inches larger (all the way around) than the duct. The duct must be
centered within this opening.

Outside Duct Work Protection

To protect the outside end of horizontal duct work from the weather, a 90° elbow bent
downward should be installed where the exhaust exits the building. If the exhaust duct work travels
vertically up through the roof, it should be protected from the weather by using a 180° turn to point

of the duct as clearance from the nearest obstruction. Do not use screens or caps on the outside
opening of the exhaust duct. The ducting 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. Provide inspection doors for periodic clean­out of lint from the main duct.

If it is not feasible to provide separate exhaust ducts for each dryer, ducts from the
individual dryers may be channeled into a common main duct. Each dryer is provided with a back
draft damper. The individual ducts should enter the bottom or side of the main duct at an angle not

duct is added.

Inadequate exhaust facilities may cause high temperature limit switches or airflow switches
to shut off the dryers. Do not

disable the switches, which are provided for your safety. Instead,
investigate the exhaust ducting. Any obstruction or air friction due to numerous elbows / fittings in
the ducting will slow the passage of air through the system with resulting inefficiency and potential
fire hazard.

1. Piping / Connections

All components / materials must conform to National Fuel Gas Code Specifications or in
Canada, the Canadian Installation Codes (for General Installation and Gas Plumbing). 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’s being supplied.

The dryer is provided with a 1 – inch N.P.T. inlet pipe connection extending out the back
area of the burner box. The minimum pipe size connection (supply line) to the dryer is 1 – inch
N.P.T. For ease of servicing, the gas supply line of each dryer must have its own shut – off valve.

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 supply 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.

Consistent gas pressure is essential at all gas connections. It is recommended that a 1 – inch
pipe gas loop be installed in the supply line serving a bank of dryers. An in – line pressure regulator
must be installed in the gas supply line (header) if the (natural) gas pressure exceeds 12.0 inches of
water column pressure.

IMPORTANT

: A water column pressure of 3.5 to 4.0 inches for natural gas and 11.0 inches for

L.P. dryers is required at the gas valve pressure tap of each dryer for proper and
safe operation.

A 1/8 – inch N.P.T. plugged tap, accessible for a test gauge connection, must be installed in
the main gas supply line immediately upstream of each dryer.

IMPORTANT

: Pipe joint compounds that resist the action of natural and L.P gases must be used.

IMPORTANT: Test all connections for leaks by brushing on a soapy water solution (liquid

detergent works well).

G. STEAM INFORMATION

Piping must be installed in accordance with good commercial steam system practice. Care
must be exercised when leveling steam dryers in final position. After leveling the dryer, check the
downward pitch of the heat exchanger from front to rear with a level. Likewise, check the
downward pitch of the return condensate manifold toward its outlet part. Absence of these
downward pitches will result in probable water hammer and premature heat exchanger fracture and
leakage.

The presence of condensate in the steam will cause water hammer and subsequent heat
exchanger failure. The steam supply connection must be taken from the top of a well-dripped steam
main. If the supply run-out to the dryer exceeds 20 feet, it should be dripped just before the control
valve with a proper trap and dirt pocket.

It is your responsibility to have ALL

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

IMPORTANT: Failure to comply with the requirements stipulated in this manual can result in

component failure which will VOID THE WARRANTY.

2. Installation Instructions

To insure that an adequate supply of steam is provided, be sure that the steam supply and
steam return lines are sized and laid out as stipulated in this manual. Inadequate steam supply and
steam return lines or improper steam plumbing will result in poor performance and can cause
component failure. Clean, dry, regulated 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 will cause water hammer and subsequent
heat exchanger failure. The steam supply connection into the main supply line must be made with a
minimum 10” riser. This will prevent any condensate from draining towards the dryer.

The steam supply piping to the dryer must include a 12" rise 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.

Shut-off valves for each dryer should be installed in the supply, return, and drip trap return
lines. This will allow the dryer to be isolated from the supply and return mains if the dryer needs
maintenance work.

Install a float and thermostatic steam trap and check valve at least 12” below steam coil as
near to the coil as possible.

A vacuum breaker should be installed in the piping. This will prevent the condensing steam
from causing a vacuum inside the coil and possibly damaging the coil.

The supply and return lines 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 coil damage. All horizontal runs of steam supply piping should be pitched ¼”
every foot back towards the steam supply header, causing any condensate in the line to drain to the.
Header. Install a bypass trap in any low point to eliminate wet steam.

Do not

elevate the condensate return line after the float and thermostatic trap. Drain only by

gravity into a properly vented low pressure return line or condensate tank.

compressed air line just before the dryer connection. This is necessary to insure that correct and
clean air pressure is achieved.

4. Steam Damper System Operations

The dryer steam damper, as. Allows the coil to stay constantly charged eliminating repeated
expansion and contraction. When the damper is opened, the air immediately passes through the
already hot coil, providing instant heat to start the drying process. When the damper is closed,
ambient air is drawn directly into the basket (tumbler), allowing a rapid cool down.

Procedure

IMPORTANT: Dryer blower motor impeller /
fan must turn in the direction indicated on
the directional decal, otherwise dryer
efficiency will drastically be reduced and
premature component failure can result.

HEAT CIRCUIT OPERATIONAL TEST
a. Gas Models

1) 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.

2) The dryer is equipped with a direct spark
ignition (DSI) system which has internal
diagnostics. If ignition is not established
after the first attempt, the heat circuit DSI
module will lock out until it is manually
reset. To reset the DSI system, open and
close main door and restart dryer (press the
"ENTER/START" key).

NOTE: During the purging period, check to
be sure that ALL gas shut-off valves are
open.

Natural gas: 3.5 to 4.0” water column.
L.P. Gas: 10.5 to 11.0” water column.

b. Steam Models

1) Check to insure that steam damper is
functioning properly.

a) 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.

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

IMPORTANT: The drying cylinder is treated
with a protective coating. Tumble old
clothes or material in the basket (tumbler),
using a mild detergent to remove the
protective coating.

8. Each dryer should be operated through
one complete cycle to assure that no further
adjustments are necessary and that ALL
components are functioning properly.

3) 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: Water column pressure requirements
(measured at the gas valve pressure tap):

Make a complete operational check of ALL
operating controls.

1) Each microprocessor controller has
been preprogrammed by the factory with
the most commonly used program
selections. A listing of factory programs is
