ADC HBG76 Preparation for Operation/Start-Up, Preoperational Test, Preoperational Instructions

Warning

!Electrical power must be provided to the dryer at all times. If the main electrical power supply

to the dryer is disconnected, the fire suppression system is inoperative!!

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.

•GAS MODELS – Check to ensure that the dryer is connected to the type of heat/gas indicated on the dryer data label.

•GAS MODELS – Be sure that all gas shutoff valves are in the open position.

•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.

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

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

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.

Gas Dryers

Open all shutoff valves.

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.

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

A gas pressure test should be taken at the gas valve pressure tap of each dryer to ensure that the water column pressure is correct and consistent.

Note: Water column pressure requirements (measured at the pressure tap of the gas valve body) must be verified.

Important: In most cases 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.

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

Make a complete operational check of all operating controls.

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.

Microprocessor 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.

Preoperational Instructions __________

Important: For more detailed information regarding the microprocessor controller (computer), refer to the microprocessor user’s manual included with the dryer.

Coin Models

Microprocessor Controller (Computer)

When the microprocessor controller (computer) is in the ready state, the L.C.D. screen will display “Ready, Insert $XX.XX (amount) to Start”.

Insert coin(s). Once the correct “Amount to Start” has been inserted, the L.C.D. will display “Select Temperature”.

Select temperature by pressing “HI,” “MED,” or “LO.” The cycle will start and the L.C.D. will display the Dry Cycle selected and the remaining time.

The dryer will continue through the drying and cooling cycles, until the vended time has expired.

Note: To stop the dryer, open main door. Continuation of the cycle will resume only after the door has been closed and any one of the 3 temperature selections is pressed.
