The dryer installation must meet the AMERICAN NATIONAL STANDARD, NATIONAL FUEL GAS CODE ANSI
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.) 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, unless elevation require- ments of over 2,000 feet 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 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" touch pad on the keyboard of microprocessor controller (computer).
c.The dryer will start and display will show "dRYING MANUAL CYCLE, 30 MIN REMAIN," then display the drum temp.
NOTE: Pressing touch pads 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. (See 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
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.
NOTE: Water column pressure requirements (measured at the pressure tap on the gas valve body): Natural Gas - 3.5 to 4 inch water column
L.P. Gas - 10.5 to 11 inch water column.
6.If computer program changes are required, refer to the Phase 6 OPL Operator's Manual (ADC P/N 113022) for details.
7.The dryer should be operated through one complete cycle to assure that no further adjustments are neces- sary and that all components are functioning properly.
8.Check the electric service phase sequence. While the dryer is operating, check to see if the blower wheel is rotating in the proper direction. Looking from the front, the blower wheel should spin in the clockwise direction. If so, the phasing is correct. If the phasing is incorrect, reverse two (2) leads at connections L1, L2 or L3 of power supply to the dryer.
