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

3.GAS MODELS ONLY

a.When a gas dryer is first started (during initial start-up), it has a tendency not to ignite on the first ignition attempt. This is because the gas supply piping is filled with air, so it may take a few minutes for the air to be purged from the lines.

b.If the dryer is equipped with a Direct Spark Ignition (DSI) system, the DSI control module has internal diagnostics. If ignition is not established within three (3) attempts, the heat circuit in the DSI control module will “LOCKOUT” until manually reset. To reset the DSI system, open and close the main door and restart the dryer.

c.If the dryer is equipped with a Hot Surface Ignition (HSI) system, the HSI control module has internal diagnostics. If ignition is not established after the first attempt, the heat circuit in the HSI control module will “LOCKOUT” until manually reset. To reset the HSI system, open and close the main door and restart the dryer.

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

Natural Gas -------------------

3.5 Inches (8.7 mb) Water Column.

Liquid Propane (L.P.) Gas ----

10.5 Inches (26.1 mb) Water Column.

IMPORTANT: There is no regulator provided in an L.P. dryer. The water column pressure must be regulated at the source (L.P. tank), or an external regulator must be added to each dryer.

4.Make a complete operational check of ALL safety related circuits:

a.Door Switch(es)

b.Hi-Limit Thermostats

c.Cycling Thermostat

d.GAS AND ELECTRIC MODELS ONLY - Sail Switch

NOTE: The sail switch can be checked for proper operation by opening the lint drawer. While pushing the lint drawer switch in, start a drying cycle. The heating unit should not activate (wait 30-seconds). If heat does activate, make the necessary adjustments to the sail switch.

The D-40 is equipped with a large capacity tumbler that can accommodate significant loads, making it an ideal choice for businesses that require efficient drying solutions.

The dryer utilizes a state-of-the-art microprocessor control system, allowing users to program multiple drying cycles tailored to specific fabric types or customer preferences. This technology enables precise drying times and temperatures, which helps to prevent damage to garments while maximizing efficiency. The control panel is user-friendly, featuring clear displays and intuitive navigation, ensuring that operators can quickly set up and adjust cycles as needed.

In terms of energy efficiency, the D-40 is engineered with advanced drying technologies that reduce utility costs. Its high-performance gas burners and optimized airflow design allow for rapid heat distribution, which significantly shortens drying times. The dryer also features a reliable heat exchanger system that ensures consistent heat output while minimizing energy consumption.

Another noteworthy characteristic of the D-40 is its sound-dampening design. The dryer is equipped with noise-reduction technology, allowing it to operate quietly, which is particularly beneficial in environments where noise may disrupt customers or staff.

Safety features are also of paramount importance in the D-40’s design. It includes a protective door interlock system that ensures the dryer cannot operate when the door is open, reducing the risk of accidents. Moreover, the D-40 has been designed with easy access for maintenance, making it simpler for technicians to perform routine checks and repairs.

In conclusion, the American Dryer Corp D-40 stands out in the competitive landscape of commercial dryers by combining high-capacity performance with energy efficiency, advanced technology, and a commitment to safety and durability.
