c. Water circulation system. The water circulation system on the Versamat
11C-MW (fig 2-4) operates from regulated pressure, through a water mixing valve
and flow meter.
It provides fresh water to the deep wash and spray tanks
through the jacket side of the heat exchanger. Water temperature for the wash
water and heat exchanger is regulated by a thermostatically controlled valve in
the mixing valve.

d. Developer and fixer replenishment system.
The developer and fixer
replenishment systems (fig 2-3 and 2-5) pump developer and fixer to the
processing tanks from the storage tanks. The replenisher pumps can be operated
continuously or automatically controlled by a detector roller system.
Both
systems are energized by a rocker switch, AUTO-ON-MAN. NOTE: The weir blocks
shown in figure 2-5 control the direction of flow for the fixer.
e. Air circulation system.
The air circulation system is designed to
circulate heated air through the dryer section of the processor. The air is
heated by thermostatically controlled heaters. A blower, located beneath the
processing tanks, forces the air through the system.
Make-up air is added
through a grill at the dryer end of the processor, and an equivalent amount of
moist air is discharged through the dryer exhaust to maintain proper relative
humidity in the dryer. Approximately 250 cubic feet per minute of
