American Dryer Corp ADH-75, ADH-170 Preparation for Operation/Start-Up, Preoperational Test

Page 29

Preparation for Operation/Start-Up ___

The following items should be checked before attempting to operate the dryer:

Read all “CAUTION,” “WARNING,” and “DIRECTION” labels attached to the dryer.

Check incoming supply voltage to be sure that it is the same as indicated on the data label. In the case of 208 VAC or 240 VAC, the supply voltage must match the electric service exactly.

ELECTRIC MODELS – The sail switch damper assembly was installed and adjusted at the factory prior to shipping. However, each sail switch adjustment must be checked to ensure that this important safety control is functioning. (Refer to Sail Switch Adjustment in the Preoperational Test section).

Be sure all back panels (guards) and electric box covers are in place.

Be sure the service doors are closed and securely in place.

Be sure the lint door/drawer is securely in place.

Rotate the tumbler (drum) by hand to be sure it moves freely.

Check bolts, nuts, screws, terminals, and fittings for tightness and security.

STEAM MODELS – check to ensure that a clean, dry, regulated air supply (80 psi [5.51 bar]) is on the dryer (with air-operated damper system only).

STEAM MODELS – Check to ensure all steam shutoff valves are open.

STEAM MODELS – Check steam damper operation.

Check tumbler bearing setscrews to ensure they are all tight.

Check that the vent is connected to the dryer and is exhausted to the outdoors.

Preoperational Test ___________________

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.

Turn on electric power to the dryer.

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

Steam Dryers

Check to ensure that steam damper is functioning properly. The steam damper should not “slam” (open or closed) when it reaches the end of (piston) travel. Additionally, the steam damper should not bind and/or stop during travel. If either of these conditions occur, the flow control must be adjusted. Refer to the Steam Damper Air Piston (Flow Control) Operation Adjustment instructions in the Steam Information section.

Electrical Dryers

Check to ensure that electric oven/contactor assembly is activating.

Safety Related Circuits

Make a complete operational check of all safety related circuits:

Door Switch(es)

Hi-Limit Thermostats

Sail Switch (for Electric Models Only)

Sail Switch Adjustment – To check for proper sail switch operation (for electric models only), open the main door and while holding main door switch plunger in, start dryer. Dryer should start but heat circuit should not be activated (on). If the heat system is activated, the sail switch is improperly adjusted and must be adjusted by bending the actuator arm of the sail switch toward the burner box. If the actuator arm is bent too far toward the burner box of the dryer, the dryer may not have heat when needed. After any adjustment to the sail switch, the above procedure must be repeated to verify proper operation of the sail switch.

The dryer should be operated through 1 complete cycle to ensure that no further adjustments are necessary and that all components are functioning properly.

Make a complete operational check of all operating controls.

For microprocessor model check controller (computer) programs/selections: each microprocessor controller (computer) has been preprogrammed by the factory with the most commonly used parameter (program) selections. If computer program changes are required, refer to the computer programming manual which was shipped with the dryer.

Tumbler Coating

The 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 tumbler to remove this coating.

3-Phase (3ø) Electric Service

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

Important

!If the blower/fan is rotating in the wrong direction, it will drastically reduce drying efficiency and it can

also cause premature component failure.

Spin and Dwell (Stop) Times Adjustment

Reversing tumbler dryers should never be operated with less than a 66% load (dry weight), since the load’s weight affects tumbler coast time during a direction reversal command. It is important that the tumbler come to a complete stop prior to starting in opposite direction.
