Operation Manual specific to the refrigeration unit(s) being installed. NOTE: All wiring to be performed in accordance with the National Electrical Code and/or regulatory agency for the installation locality. All wiring that enters the Sentry II control box must be sealed with cord grips or liquid-tight conduit connectors.
IMPORTANT NOTE: Mueller warrants to the original purchaser/user that the Mueller factory calibration of a Mueller milk cooler will not be affected (i.e. exceed the tolerances prescribed by the National Institute of Standards and Technology) by distortion or structural change for a period of five (5) years from the date of installation or sixty-six (66) months from the date of shipment from the Company factory, whichever occurs first.
7. Ensure that the final location and position complies with all regulations for the installation locality, including the proper height of the milk outlet and the proper dimensions beneath and around the milk cooler. Figure 4 - Leveling the Milk Cooler Sentry II with Auto-Dosing Assembly Operating Instructions Effective April 1, 2000...
If the milk cooler is bulkheaded through a wall, the wall must be free-standing and not load bearing against the milk cooler. Mueller offers an optional steel-formed structural support channel that may be installed in masonry walls to prevent the wall from bearing load on the milk cooler. Contact Mueller’s Sales Department for availability and pricing.

SECTION 4.0 - SENTRY II TEMPERATURE CONTROL Sentry II Temperature Control and Thermocouple Sensor The Sentry II control uses an electronic temperature control with digital display and a Type “T” thermocouple sensor. The following installation and calibration procedures are very important to ensure accurate sensing of the milk temperature.
Cut and insulate the foil shield and drain wire of the thermocouple extension cable at the top-rear junction box. The drain wire should be grounded (one end only) at the Sentry II control cabinet. Route the thermocouple extension cable from the rear junction box to the wall-mounted Sentry II.
Use non-metallic wire nuts, Mueller Part No. 8822361, to make all spliced thermocouple connections. If thermocouple extension cable is required, Mueller Part No. 8820166, connect the drain wire to the electrical ground at the Sentry II enclosure and cap and insulate the foil shield and drain wire at the opposite end.
Sentry II Temperature Control Lock and Unlock Features The temperature control is equipped with a locking feature to prevent unauthorized adjustments to the calibration, temperature set points, and unit of measure. Unlock - To unlock the temperature control for adjustment, press and hold the keys (see Figure 28) simultaneously for two seconds.
Lock the temperature control by pressing and holding the keys simultaneously for 4 seconds. When released the display will blink once indicating a successful lock, otherwise repeat the process. Sentry II with Auto-Dosing Assembly Operating Instructions Effective April 1, 2000...
The display will blink once when the keys are released, informing you that the control was successfully locked. See Section 4.6. Sentry II Temperature Control Unit of Measure (Fahrenheit or Celsius) 1. Unlock the temperature control as instructed in Section 4.6.
Store chemicals in an area that prevents access by children or unauthorized individuals.

Determining Water Usage Requirements The PLC in the Sentry II is supplied with a potentiometer that allows the volume of fill water to be adjusted for each specific installation. As the timer is turned clockwise to increase the volume of wash water, it automatically increases the electric drain time to ensure adequate drainage at the end of each cycle.
Wash Cycle Timing Sequence The Sentry II provides several programming options for the wash cycles. See Section 6 for detailed information. Chart 1 - (Detergent Wash or Complete Wash) NOTE: Fill and drain times are charted with the PLC potentiometer turned to the far counterclockwise position.
Chart 2 - (Acid Cycle or Sanitize Cycle) NOTE: Fill and drain times are charted with the PLC potentiometer turned to the far counterclockwise position. See Section 5.6 and Figure 31. Sentry II with Auto-Dosing Assembly Operating Instructions Effective April 1, 2000...
