WFS 1545 Operations Manual
uses a Tecumseh AWA45203XNXC condensing unit with a custom made evaporator. It requires 208
-220 VAC 50-60 hz electrical power.
The evaporator uses custom made titanium coils enclosed in schedule 80 PVC housing. The wetted
surfaces are PVC and titanium making the heat exchangers impervious to the effects of DI water.
NOTE: The condensing section of unit should be periodically cleaned. Use clean dry compressed air to blow
dust out from cooling fins. For specific detailed information concerning the Tecumseh condensing unit see
the design data page in the appendix.

TEMPERATURE CONTROLLER
The water temperature for the Process Circuit is controlled by a RANCO ETC111000020 Electronic
Temperature Controllers. This is mounted on the side of the main control cabinet. Water
temperature can be increased or decreased by use of the up or down arrows on the face of the
RANCO unit.
NOTE: For additional information see the Design Data section in the appendix.
e.
FLOAT VALVE
A Hudson Float Valve is installed at a fixed position in the reservoir to maintain proper level and
compensate for evaporation and minor leaks. It is recommended that a separate supply source be
available for initial commissioning.
