3.10 Drain Discharge
Cooldown System with
Cold Water Injection
Washer drain system is piped to automatically cool all drain dis-
charges using building cold water supply.
During draining function of each phase, cold tap water is injected
into washer drain line as washer drain discharges are sent directly to
building drain system.
3.11 Exhaust Fan
During unit operation, exhaust fan removes residual vapors from
wash chamber and directs vapors to building exhaust duct.
3.12 Vapor Condensing
Exhaust System
Vapor Condensing Exhaust System consists of a vapor condenser,
mounted to side of washer, and an exhaust fan, mounted on top of
washer. Unit width and height are increased by 14" and 7.5" (355 mm
and 190 mm).
During unit operation, residual vapors are automatically removed
from wash chamber and directed to vapor condenser. Vapors are
then cooled, condensed, and directed to building drain system.
3.13 Heat Exchanger
Washer is equipped with a steam heat exchanger and valving sys-
tem to preheat incoming fill water, reducing normal water/solution
heat-up time.
System is fully automatic and works during filling phase of all cycle
treatments.
