3 SECTION I IMPOR T ANT INFORMA TION A. RECEIVING AND HANDLING The dryer is shipped in a protective stretch wrap cover with protective cardboard corners and top cover (or optional box) as a means of preventing damage in transit. Upon delivery , the dryer and packaging, and wooden skid should be visually inspected for shipping damage.

W ARNING: The dryer must never be operated with any of the back guards, outer tops, or service panels removed.
5 W ARNING: DO NOT dry mop heads. Contamination by wax or flammable solvents will create a fire hazard. W ARNING: DO NOT use heat for drying articles that contain plastic, foam, sponge rubber , or similarly textured rubber materials. Drying in a heated basket (tumbler) may damage plastics or rubber and may be a fire hazard.
6 SECTION II SPECIFICA TIONS A. SPECIFICA TIONS * MDG30V reversing dryer available with 3-phase (3ø) 1/2 HP (0.373 kw) motors standard. ** Size of piping to dryer varies with installation conditions. Contact factory for assistance. NOTE: Manufacturer reserves the right to make changes in specifications at any time without notice or obligation.
7 NOTE: Manufacturer reserves the right to make changes in specifications at any time without notice or obligation. Specifications MDG30V.
8 SECTION III INST ALLA TION PROCEDURES Installation should be performed by competent technicians in accordance with local and state codes. In the absence of these codes, the installation must conform to applicable American National Standards: ANSI Z223.
9 B. LOCA TION REQUIREMENTS Before installing the dryer , be sure the location conforms to local codes and ordinances. In the absence of such codes or ordinances the location must conform with the National Fuel Gas Code ANSI.Z223.1 LA TEST EDITION, or in Canada, the installation must conform to applicable Canadian Standards: CAN/CGA-B149.
10 C. DR YER ENCLOSURE REQUIREMENTS Bulkheads and partitions should be made of noncombustible materials and must be located a minimum of 12-inches (30.48 cm) above the dryer ’ s outer top; except along the front of the dryer, which may be closed if desired.
11 D. FRESH AIR SUPPL Y REQUIREMENTS The MDG30V 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 . As a general rule, an unrestricted air entrance from the outdoors (atmosphere) of a minimum of 1-1/2 square feet (0.
12 E. 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 ener gy , and shutdown of the burner by the airflow (sail) switch, burner hi-limits, or lint chamber hi-limit protector thermostat.
13 SINGLE DR YER VENTING IMPOR T ANT : For exhaust duct runs over 20 feet (6.1 meters) a minimum size of 10-inches (25.4 cm) must be used. HORIZONT A L VENTING When a single 8-inch (20.32 cm) horizontal vent is used, the ductwork to the outlet cannot exceed 20 feet (6.
14 VER TICAL VENTING When vertical single 10-inch (25.4 cm) venting is used (refer to Illus. B below ), the ductwork from the dryer to the outside outlet cannot exceed 40 feet (12.19 meters). This calculation compensates for the use of a maximum of three (3) elbows including the two (2) elbows creating the 180° (turned downward) outside outlet.
15 MUL TIPLE DR YER (COMMON) VENTING If it is not feasible to provide separate exhaust ducts for each dryer , ducts for individual dryers may be channeled into a common main duct.
16 HORIZONT A L VENTING Illus. C VER TICAL VENTING Illus. D.
17 IMPOR T ANT VENTING REMINDERS 1. Ductwork size and installation should be done by a qualified professional. 2. The dryer must be exhausted to the outdoors. 3. Ductwork should be routed as short as possible to the outdoors with as few elbows as possible.
18 F . ELECTRICAL INFORMA TION 1. Electrical Requirements It is your responsibility to have ALL electrical connections made by a properly licensed and competent electrician to assure that the electrical installation is adequate and conforms to local and state regulations or codes.
19 NOTE: Component failure due to improper voltage application will VOID THE W ARRANTY . 3. Grounding A ground (earth) connection must be provided and installed in accordance with state and local codes. In the absence of these codes, grounding must conform to applicable requirements of the National Electrical Code ANSI/NFP A NO.
20 If local codes permit, power to the dryer can be made by the use of a flexible U.L. listed power cord or 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 .
21 5. 3-Phase (3ø) W iring Connections/Hookup The only electrical input connections to the dryer are the 3-phase (3ø) power leads (L1, L2, L3, and sometimes Neutral) and ground. Single-phase (1ø) power for the control circuit is done internally to the dryer .
22 IMPOR T ANT : Figures shown are for non-reversing models only . For reversing models contact the factory . IMPOR T ANT : The dryer must be connected to the electric supply shown on the data label that is affixed to the left side panel area behind the top control (access) door .
23 G . GAS INFORMA TION It is your responsibility to have ALL plumbing connections made by a qualified professional to assure that the gas plumbing installation is adequate and conforms to local and state regulations or codes.
24 2. T echnical Gas Data a . Gas Specifications *Measured at outlet side of gas valve pressure tap when gas valve is on. b. Gas Connections Inlet connection ------------- 1/2” N.
25 3. Piping Connections ALL components/materials must conform to National Fuel Gas Code Specifications ANSI Z223.1-LA TEST EDITION, or in Canada, CAN/CGA-B149.
26 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 12.
27 H. PREP ARA TION FOR OPERA TION/ST AR T -UP The following items should be checked before attempting to operate the dryer: 1. Read ALL “ CAUTION ,” “ W ARNING ,” and “ DIRECTION ” labels attached to the dryer .
28 I. PREOPERA TIONAL TESTS 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.
29 5. Make a complete operational check of ALL operating controls. NOTE: If computer program changes are required, refer to the computer programming section of the manual supplied with the dryer .
30 NOTES: 1 . If the Anti-Wrinkle program is active, the light emitting diode (L.E.D.) display will continue to read “donE,” and the microprocessor controller (computer) will proceed through the Anti-W rinkle program until the maximum “Active Guard T ime” has expired or until the door is opened, whichever comes first.
31 IMPOR T ANT : If the door is opened during a cycle, both the heat and motor will stop. However , the microprocessor controller (computer) will continue to count the time, either upward or downward, depending on which parameter is programmed.
32 K . SHUT DOWN INSTRUCTIONS If the dryer is to be shut down (taken out of service) for a period of time, the following must be performed: 1. Discontinue power to the dryer either at the external disconnect switch or the circuit breaker . 2. Discontinue the heat supply: a.
