Page 12

IMPORTANT: Failure to comply with these codes or ordinances and/or the requirements stipulated in this manual can result in personal injury or component failure.

The gas dryer installation must meet the American National Standard, National Fuel Gas Code ANSI Z223.1- LATEST EDITION, or in Canada, the Canadian Electrical Codes Parts 1 & 2 CSA C22.1-1990 or LATEST EDITION (for Electrical Connections) as well as, local codes and ordinances, and must be done by a qualified technician.

NOTE: Undersized gas piping will result in ignition problems and slow drying and can create a safety hazard.

The dryer must be connected to the type of gas (natural or L.P. [liquid propane]) indicated on the dryer data label. If this information DOES NOT agree with the type of gas available, contact the distributor who sold the dryer or contact the factory.

The gas input ratings shown on the dryer data label are for elevations up to 2,000 feet (610 meters), unless elevation requirements of over 2,000 feet (610 meters) were specified at the time the dryer order was placed with the factory. The adjustment for dryers in the field for elevations over 2,000 feet (610 meters) are made by changing the burner orifices. If this adjustment is necessary, contact the distributor who sold the dryer or contact the factory.

NOTE: Any burner changes must be made by a qualified technician.

C. OPERATIONAL SERVICE CHECK PROCEDURE

1.Turn on electric power to the dryer.

2.To start dryer:

a.Display will read “READY.”

b.Press “E” on the keyboard (touchpad) of microprocessor controller (computer).

c.The dryer will start and the display will show “dr30.”

NOTE: Pressing keyboard (touchpad) selections “A,” “B,” “C,” “D,” and “F” will also start the dryer. Six (6) preprogrammed drying cycles (“A” through “F”) have been stored in the computer’s memory. (Refer to the Computer Operator’s Manual for details.)

3.Make a complete operational check of ALL the operating controls to assure that the timing is correct, temperature selection switches are functioning, etc.

4.Make a complete operational check of ALL safety-related circuits - door switch(es), hi-limit thermostat, sail switch, cycling thermostats, etc.

5.For gas dryers a gas pressure test should be taken at the gas valve pressure tap of each dryer to assure that the water column pressure is correct and consistent.
