American Dryer Corp AD-24 Phase 7 installation manual Basket Tumbler Coating

NOTE: Gas model dryers are equipped with an ignition system, which has internal diagnostics. If ignition is not established after one (1) time, the heat circuit in the ignition module will attempt two (2) more ignitions (total of three [3] ignition attempts). If there is no flame after the third ignition attempt, the module will lock out until it is manually reset. To reset the ignition system, open and close the main door and restart the dryer.

b.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 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 Thermostats

d.Sail Switch

NOTE: The sail switch can be checked for proper operation by opening the lint door while the heating circuit (gas burner/electric oven) is active (on). The heating unit should shut off within a few seconds. If not, make necessary adjustments to the sail switch.

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.

6.The dryer should be operated through one (1) complete cycle to ensure that no further adjustments are necessary and that ALL components are functioning properly.

BASKET (TUMBLER) COATING

The basket (tumbler) is treated with a protective coating. We suggest dampening old garments or cloth material with a solution of water and nonflammable mild detergent and tumbling them in the basket (tumbler) to remove this coating.

7.Check the electric service phase sequence (3-phase [3ø] models only). While the dryer is operating, check to see if the blower wheel (impellor/fan) is rotating in the proper direction. Looking from the front, the blower wheel (impellor/fan) should spin in the clockwise (CW) direction. If it is, the phasing is correct. If the phasing is incorrect, reverse the two (2) leads at connections L1, L2, or L3 of the power supply to the dryer.
