Preoperational Tests | American Dryer Corp ML-175DR specs

J. PREOPERATIONAL 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.

1.Turn on electric power to the dryer.

2.Make sure the main door is closed and the lint drawer is securely in place.

3.Refer to the Operating Instructions for starting your particular model dryer.

4.Check to ensure that the basket (tumbler) starts in the clockwise (CW) direction. Additionally, check the direction of the blower motor impellor (fan) to ensure that the impellor (fan) rotates in the clockwise (CW) direction as viewed from the front. If it is, the phasing is correct. If the phasing is incorrect, reverse two

(2) of the leads at L1, L2, or L3 of the power supply connections made to the dryer.

IMPORTANT: Dryer blower motor/pulley that drives the impellor/fan (squirrel cage) when viewed from the back of the dryer must turn in the counterclockwise (CCW) direction, otherwise the dryer efficiency will be drastically reduced and premature component failure can result.

5.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 three (3) attempts, the heat circuit DSI module will LOCKOUT until it is manually reset. To reset the DSI system, open and close the main door and restart the dryer (press the “START” key).

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

3)Once ignition is established, a gas pressure test should be taken at the gas valve pressure tap of each dryer to ensure that the water column (W.C.) pressure is correct and consistent.

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

Natural Gas ________________ 3.5 Inches (8.7 mb) Water Column.

Liquid Propane (L.P.) Gas _____ 10.5 Inches (26.1 mb) Water Column.

ML-175DR specifications

American Dryer Corp ML-175DR is a high-efficiency, state-of-the-art hand dryer designed to provide a superior drying experience in public restrooms and commercial environments. With its sleek and modern design, the ML-175DR not only enhances the aesthetic appeal of any facility but also offers numerous practical benefits.

One of the standout features of the ML-175DR is its powerful motor, which generates a strong airflow of up to 17,000 RPM. This ensures that hands are dried quickly and effectively, taking only about 10 to 15 seconds to achieve optimal dryness. This efficiency significantly reduces waiting time for users, making it a convenient choice for high-traffic areas.

The ML-175DR incorporates advanced sensor technology that allows for touchless operation. The built-in infrared sensors detect the presence of hands beneath the nozzle, automatically activating the drying process. This feature not only promotes hygiene by minimizing contact with surfaces but also helps conserve energy, as the dryer only operates when needed.

Another noteworthy characteristic of the ML-175DR is its eco-friendly design. It is constructed with energy-efficient components that use significantly less power compared to traditional hand dryers. This not only reduces electricity costs but also supports sustainability efforts by minimizing the carbon footprint associated with restroom facilities.

Moreover, the ML-175DR includes an adjustable airspeed feature, allowing users to customize their drying experience according to different environments. Whether it’s a busy restaurant or a quiet office, the adjustable settings enable optimal performance tailored to the specific needs of each location.

In terms of durability, the ML-175DR is built with heavy-duty materials that ensure longevity, making it a reliable choice for various commercial and public settings. Its robust construction is resistant to wear and tear, which is essential for hand dryers that see frequent use.

In summary, the American Dryer Corp ML-175DR stands out for its powerful yet efficient drying capabilities, touchless operation, eco-friendly design, adjustable airspeed, and durable construction. These features make it an excellent choice for modern facilities looking to enhance hygiene, improve user experience, and promote sustainability.
