Cooldown with Side
Tank and Temperature
Guarantee
A separate tank is typically mounted along service side of washer to
temporarily retain and cool all drain discharges (see Figure 3-9).
NOTE: Location of drain discharge side tank may change depending
on other options ordered with washer.
During draining function of each phase, if sump water temperature is
over 140ºF [60ºC], solution/water in sump is automatically pumped to
side tank where cold tap water is added. Cold water remains on until
water temperature in side tank reaches programmed set point. Once
cooled to set temperature, side tank gravity drains to building drain
system.

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. Cold water remains on until sump drain valve
closes.
