7 Specifications MDG-30 Fast Dry NOTE : Manufacturer reserves the right to make changes in specifications at any time without notice or obligation..
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 NA TIONAL ST ANDARDS: National Fuel Gas Code ANSI.
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 twelve (12) inches 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 The MDG-30 Fast Dry air supply (makeup air) must be given careful consideration to assure proper perfor- mance of each dryer . An unrestricted source of air is necessary for each dryer .
12 E. EXHAUST REQUIREMENTS Exhaust duct work should be designed and installed by a qualified professional. Improperly sized duct work 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-limit, or lint chamber hi-heat protector thermostat.
13 SINGLE DR YER VENTING IMPOR T ANT : For exhaust duct runs over 30 feet a minimum size of 12 inches must be used. H ORIZONT AL V ENTING When horizontal single 10-inch venting is used, the duct work to the outlet cannot exceed 30 feet (refer to Illus.
14 If the length of the duct run or quantity of elbows used exceeds the above noted specifications, the cross section area of the duct work must be increased in proportion to the number of elbows or duct run added. IMPOR T AN T : For extended duct work runs, the cross section area of the duct can only be increased to an extent.
15 MUL TIPLE DR YER (Common) VENTING H ORIZONT AL V ENTING 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. Each dryer is provided with a back draft damper .
16 Illus. C (refer to the previous page 15 }) shows the minimum cross-section area for horizontal multiple dryer venting. These figures must be increased in proportion if the main duct run from the last dryer to where it exhausts has numerous elbows or is unusually long.
17 IMPOR T ANT VENTING REMINDERS 1. Duct work size and installation should be done by a qualified professional. 2. The dryer must be exhausted to the outdoors. 3. Duct work 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 with 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 Electric 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 a. Gas Model Dryers ONL Y 1) 3-Phase (3 ø ) W iring Connection and Hookup For gas dryers manufactured for operation at 3-phase (3 ø ), the electrical connections are made at the power distribution block located in the service box at the rear , upper left corner of the dryer .
22 IMPOR T ANT : The dryer must be connected to the electric supply shown on the data label that is affixed to the back side of the upper or top control door . In the case of 208 V AC or 230/240 V AC, the supply voltage must match the electric service specifications of the data label exactly .
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 with local and state regulations or codes.
24 2. T echnical Gas Data a . Gas Specifications b. Gas Connections Inlet connection ------------ 3/4" inch N.P .T . Inlet supply size ------------ 3/4" inch N.P .T . (minimum) Btu/hr input (per dryer) --- 176,000 (MDG-30D Fast Dry) 1) Natural Gas Regulation is controlled by the dryer's gas valve's internal regulator .
25 3. Piping Connections ALL components and materials must conform to National or Canadian Gas Code specifications. 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.
26 Consistent gas pressure is essential at ALL gas connections. It is recommended that a 3/4-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.
27 H. PREP ARA TION FOR OPERA TION and 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-W rinkle program is active, the L.E.D. (light emitting diode) 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 b. Select T emperature The dryer will start, the L.E.D. (light emitting diode) display will read the temperature cycle selected, and the drying time portion of the L.E.D. (light emitting diode) display will read "00" and count upward as time elapses, or the vended time will count downward, depending on the program parameter setting.
32 2) Press the "E" on the touchpad of the keyboard. 3) The L.E.D. (light emitting diode) display will quickly show "Ld30," "LC04," "F180." The dryer will start, and the L.E.D. (light emitting diode) display will show "dr30.
