STEAM DRYERS
Clean the steam coil fins. We suggest using compressed air and a vacuum cleaner with brush attachment.
NOTE: When cleaning steam coil fins, be careful not to bend the fins. If fins are bent, straighten by
using a fin comb, which is available from any local air-conditioning supply house.
90 DAYS
Remove lint from around tumbler, drive motors, and surrounding areas. Remove lint from the gas valve burner
area with a dusting brush or vacuum cleaner attachment.
Impellor (fan/blower) shaft bearings should be lubricated using Shell Alvania NLGI2 or its equivalent. Generically,
this grease would be described as an NLGI grade 2 multipurpose industrial grease with a lithium thickener and
mineral base oil.
Check to make sure that the setscrews on the impellor/fan shaft bearings are tight.
NOTE: To prevent damage, avoid cleaning and/or touching the Direct Spark Ignitor.
Remove lint accumulation from inside.
6 MONTHS
Inspect and remove lint accumulation in customer furnished exhaust ductwork system and from dryer’s internal
exhaust ducting.
NOTE: THE ACCUMULATION OF LINT IN THE EXHAUST DUCTWORK CAN
CREATE A POTENTIAL FIRE HAZARD.
NOTE: DO NOT OBSTRUCT THE FLOW OF COMBUSTION AND VENTILATION AIR.
CHECK CUSTOMER FURNISHED BACK DRAFT DAMPERS IN THE EXHAUST
DUCTWORK. INSPECT AND REMOVE ANY LINT ACCUMULATION, WHICH
CAN CAUSE THE DAMPER TO BIND OR STICK.
NOTE: A back draft damper that is sticking partially closed can result in slow drying and shutdown of
the heat circuit safety switches or thermostats.
NOTE: When cleaning the dryer cabinet(s), avoid using harsh abrasives. A product intended for the
cleaning of appliances is recommended.
Check ALL V-belts for tightness and wear. Retighten, realign, or replace if required.
NOTE: V-belts should be replaced in matched sets (pairs).
