a.Outside Ductwork Protection

1)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, itshould 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:DO NOT use screens, louvers, or caps on the outside opening of the exhaust ductwork.

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 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 ductingbe avoided; use 30° and/or 45° angles instead. The shape of the exhaust ductworkis not critical so long as the minimum cross section area is provided.

IMPORTANT: The minimum duct size is18-inches(45.72 cm) for a round duct16-inchesx16-inches(40.64 cm x 40.64 cm) for a square duct.THE DUCT SIZE MUST NOT BE REDUCED ANYWHERE DOWNSTREAM OF THE DRYER.

IMPORTANT: Exhaust back pressure measured by a manometer at each basket (tumbler) exhaust duct areamust be no less than 0 andmust not exceed 0.3 inches (0.74 mb) of water column (W.C.).

17

It is suggested that the ductwork from each dryer not exceed 20 feet (6.09 meters) with no more than two

(2) elbows (excluding dryer connections). If the ductwork exceeds 20 feet (6.09 meters) or has numerous elbows, the cross-sectionalarea of the ductworkmust be increased in proportion to the length and number of elbows in it. In calculating duct size, thecross-sectionalarea of a square or rectangular ductmust be increased twenty percent (20%) for each additional 20 feet (6.09 meters) The diameter of a round exhaust ductshould be increased ten percent (10%) for each additional 15 feet (4.57 meters). Each 90º elbow is equivalent to an additional 40 feet (12.19 meters), and each 45º 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 runscannot exceed 20 feet (6.09 meters) more than the original limitations of 20 feet (6.09 meters) with two (2) elbows. When the ductwork approaches the maximum limits as noted in this manual, a professional heating, venting, and air conditioning (HVAC) firmshould be consulted for proper venting information.

ALL ductworkshould 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 jointsmust be taped to prevent moisture and lint from escaping into the building. Inspection doorsshould be installed at strategic points in the exhaust ductwork for periodic inspection and cleaning of lint from the ductwork.

18

NOTE: When the exhaust ductwork passes through a wall, ceiling, or roof made of combustible materials, the openingmust be 2-inches(5.08 cm) larger than the duct (all the way around). The ductmust be centered within this opening.

a.Outside Ductwork Protection

1)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, itshould 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:DO NOT use screens, louvers, or caps on the outside opening of the exhaust ductwork.

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 the flow andshould be spaced at least55-5/8inches (141.28 cm) apart. The main ductshould be tapered, with the diameter increasing before each individual18-inch(45.72 cm) duct is added.

IMPORTANT: TheID-170is not provided with a back draft damper. When exhausted into a multiple (common) exhaust line, a back draft dampermust be installed at each dryer duct.

IMPORTANT: No more than three (3) dryersshould be connected to one (1) main common duct.

The main duct may be any shape or cross-sectionalarea, so long as the minimum cross section area is provided. Theillustrations onpage 21 show the minimum cross section area for multiple dryer round or square venting. These figuresmust be increased 10 square inches (64.51 square centimeters) when rectangular main ducting is used, and the ratio of duct width to depthshould not be greater than3-1/2to 1. These figuresmust 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 [2]) in it. In calculating ductwork size, thecross-sectionalarea of a square or rectangular ductmust be increased twenty percent (20%) for each additional 20 feet (6.09 meters). The diameter of a round exhaustmust be increased ten percent (10%) 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).

IMPORTANT: For extended ductwork runs, the cross section area of the ductwork can only be increased to an extent. Maximum proportional ductwork runscannot exceed 20 feet (6.09 meters) (more than the original limitations of 20 feet (6.09 meters) with two (2) elbows. When the ductwork approaches the maximum limits as noted in this manual, a professional heating, venting, and air conditioning (HVAC) firmshould be consulted for proper venting information.

3. Electrical Connections

NOTE: A wire diagram is included with each dryer and is affixed to the back side of the top control (access) door.

The only electrical input connections to the dryer are the 3-phase(3ø) power leads (L1, L2, and L3), GROUND, and in the case of 4 wire service, the NEUTRAL. These electrical connections are made at the terminal block located in the service/relay box at the rear, upper left hand corner of the dryer. To gain access into this service box, the service covermust be removed.

The “LINE POWER” and the “GROUND” connections to the dryer must be made through the knock out hole at the top of the electric service/relay box. A strain reliefmust be used where the line power ground wires go into the electric service/relay box.

Providing local codes permit, power connections to the dryer can be made by use of a flexible underwriters laboratory list cord/pigtail (wire must conform to ratings of the dryer), or the dryer can be hard wired directly to the service breaker. InALL cases, a strain reliefmust be used where the wire(s) enter the dryer electrical service (relay) box.

NOTE: A CIRCUIT SERVICING EACH DRYER MUST BE PROVIDED.

4.Grounding

A ground (earth) connection must be provided and installed in accordance with state and local codes. In the absence of these codes, groundingmust conform to applicable requirements of the National Electrical Code ANSI/NFPA NO.70-LATESTEDITION, or in Canada, the installationmust 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.

NOTE: A grounding connection (terminal lug) is provided in the in the dryers electrical service/relay box at the rear, upper left hand corner of the dryer.

For added personal safety, when possible, it is suggested that a separate ground wire (sized 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 pipemust have metal to metal connectionALL the way to the electrical ground. If there are any nonmetallic interruptions, such as a meter, pump, plastic, rubber, or other insulating connectors, theymust be jumped out with no. 4 copper wire and securely clamped to bare metal at both ends.

IMPORTANT: For personal safety and proper operation, the dryermust be grounded. For proper operation of the microprocessor controller (computer), an earth (zero) ground is required.

NOTE: Grounding via metallic electrical conduit (pipe)is not recommended.
