4.4 Password
The controller is shipped with the password disabled. If you wish to enable it, see Section 5.2.2 for
operation. With the password enabled, any user can view but not change settings. Note that this provides
protection only against casual tampering.

Startup
Initial Startup
After the
Pulse
~Pure Integrated Controller Panel has been wired and the conductivity probe and
blowdown valve are plumbed and wired, the controller is ready to be started.
Supply power to the unit by switching the main power disconnect to the “ON” position. The disconnect is
located on the upper right of the panel door. All circuit breakers in the panel should be in their ON
position. The display will briefly show the message “Evapco Controller Initializing” then revert to the
Home display.
4.5.1
Temperature sensor is included as part of the electrodeless conductivity sensor.
Verify that the conductivity probe is calibrated accurately for temperature. For most
probes the factory- calibration is adequate. If the temperature calibration needs
adjustment see Section 5.3.2
4.5.2
Follow the procedure for Open Air calibration before inserting the electrodeless probe into
the process flow. Once completed, perform the steps for a One Point Process calibration.
The probes must be calibrated during initial start-up of the system (see Section 5.3.1) or
when a conductivity probe has been replaced.
4.5.3
Enter Bleed conductivity set point value. Refer to Evapco’s PPF1.0 document for the initial
recommended conductivity set point.
Once Inputs and Outputs are connected to the Pulse~Pure Panel, calibration has been completed and
Bleed set point entered, the controller will continuously manage all Inputs and Outputs within the
desired programming parameters.
4.6 Shutdown
To shut the controller down, turn off the power to the Pulse~Pure panel using the main power disconnect.
Programing remains in memory when the Pulse~Pure panel is de-energized. Shutdown only if
maintenance or troubleshooting requires the Pulse~Pure panel door to be opened, or if the cooling system
is to remain off for an extended period of time, e.g. winter shutdown. During periods of intermittent
operation the Pulse~Pure Panel should remain energized. De-energizing the Pulse~Pure panel disables
system water treatment.
