STEAM CONNECTIONS.
Both supply and return steam connections are located at
the rear of the heating coil unit (See Figure 1, Page 10-4) and are 1” NPTF
and 1/2" NPTF respectively. Steam dryers are equipped for operation at 125
psig maximum. The dryer may be operated at reduced pressures as low as 15
psig (with correspondingly reduced drying rate). Low pressure operation re­
quires large supply lines. Properly sized steam supply mains, condensate
returns, and controls are essential to satisfactory performance. All steam
connections should be performed by qualified technicians in accordance with
local codes, and operation and system maintenance should be provided by
properly licensed and competent personnel. Connections between steam supply
and coil must be provided with flexible hoses or couplings to eliminate
piping strains.* Clean lint and dirt from between coil fins regularly for
maximum air flow.
DRYING:
WARNING: Dry only articles that have been washed in water. Articles
with flammable or explosive soil must be thoroughly and carefully washed.
Drying can release volatile vapors which may result in fire or explosion.
Drying time depends upon the size of load being dried, the amount of moisture
left in the clothes by washer-extractor (extraction) type and mass of clothes,
air flow, and adequate heat. "Browning" of cloth is usually due to insufficient
rinsing. Do not dry plastic or rubberized articles in tumblers. Damage
to clothes can result from improper operation or installation, or material not
suited to tumbler drying.
LINT SCREEN:
CAUTION: Keep lint compartment clean.
GENERAL MAMENANCE AND SERVICES
JANITORIAL:
Clothes drying tumblers produce lint and the area around each
dryer should be kept clean. Besides the usual frequent cleaning of the lint
compartment, lint should also be removed from between the basket and the wrap­
pers; from up and behind the front panel in the lint compartment area; gathered
from around the loading door switch and thermostat connections and wiring; from
the burner area; and from within the motor and operator controls enclosures.
Lint should also be removed from the air vents of the motor frames, and from
inside the electrical junction boxes on the rear of the dryer. Exhaust ducts
and make-up air inlets should be examined periodically, and freed of lint at
elbows and grills. Care should be taken not to pile articles near make-up
air vents, exhaust duct exits, over the top or at the back of the dryer. These
good housekeeping suggestions should be performed at least three or four times
a year, and more frequently as conditions may indicate.
ELT CARE:
Motor and drive belts should be examined and a belt conditioner
applied. Cracked or seriously frayed belts should be replaced. Always replace
both belts. Tighten loose belts when necessary and check belt alignment
