Description of Parts, Compressed Air Requirements

IMPORTANT: Make-up air must be provided from a source free of dry cleaning fumes. Make-up air that is contaminated by dry cleaning fumes will result in irreparable damage to motors and other dryer components.

Exhaust ductwork should be designed and installed by a competent technician. Improperly sized ductwork will create excessive back pressure, which will result in slow drying, increased use of energy, and shut down of the burner by the airflow (sail) switch, burner hi-limit or lint chamber hi-heat protector thermostat. (Refer to appropriate Installation Manual for more details.)

CAUTION: Improperly sized or installed

!exhaust ductwork can create a potential fire hazard.

Compressed Air Requirements

The dryer requires an external supply of air (2.5 cfm @ 80 psi [0.07 cmm @ 5.52 bar) on the steam models, the air is necessary to operate the damper system. On both steam, as well as the gas model, the air is necessary/required for the blower air jet operation to clean lint from the impellor/ fan (squirrel cage type).

Electrical and Gas Requirements

It is your responsibility to have all electrical connections made by a properly licensed and competent electrician to assure that the electrical installation is adequate and conforms to local and state regulations or codes. In the absence of such codes, all electrical connections, materials, and workmanship must conform to the applicable requirements of the National Electrical Code ANSI/NFPA NO. 70-LATEST EDITION or in Canada, the Canadian Electrical Codes Parts 1 & 2 CSA C22.1-1990 or LATEST EDITION.

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 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.) indicated on the dryer data label. If this information does not agree with the type of gas available, contact the reseller 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 reseller who sold the dryer or contact the factory.

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

Operational Service Check Procedure

Turn on electric power to the dryer. To start dryer:

Display will read “READY.”

Press “E” on the keypad of microprocessor controller (computer).

The dryer will start to run.

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

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

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

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 in wc; L.P. Gas – 10.5 in wc

If computer program changes are required, refer to the Phase 6 OPL Operator’s Manual (ADC P/N 113022) for details.

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

Check the electric service phase sequence. While the dryer is operating, check to see if the tumbler is rotating in the proper direction. Looking from the front, the tumbler should spin in the clockwise direction. If so, the phasing is correct. If the phasing is incorrect, reverse two leads at connections L1, L2, or L3 of power supply to the dryer.
