About this task

To install the WRZ-PTR0000-0 Series Temperature Sensor Probe assembly, complete the following steps:
  1. Peel off the protective paper from the factory-installed strip of adhesive foam tape on the back of the probe mounting strap.
  2. Mount the temperature sensor probe inside the refrigerator or freezer unit away from the front, so as not to interfere with the stored contents and to eliminate any false temperature spikes when the door opens. Clean the mounting surface first to ensure that the adhesive foam tape sticks to the surface.
    Note: The mounting surface, mounting strap, and ambient temperature must be at least 50°F (10°C) when you mount the temperature sensor probe with adhesive foam tape.
  3. Support the wire lead along the inside walls of the refrigerator or freezer unit to the WRZ-STRxxxx-2 Series Wireless Refrigerator or Freezer Temperature Transmitter, run the lead through the door gap or an existing hole designed for remote temperature sensor probe installation.
    Note: Do not use an existing hole designed for electrical voltage, as this affects the temperature reading. Do not drill a hole through the wall of the refrigerator or freezer unit for the wire lead unless approved by the refrigerator or freezer manufacturer, and also approved by the customer.
  4. If you use the door gap method for installation, secure the wire lead with adhesive foam tape where the lead passes through the door gap to protect it from excessive rubbing or getting caught in the door hinge.
  5. Remove the transmitter housing from its mounting base. See Figure 1. Reverse the steps to reinstall the housing.
  6. Feed the wire lead through the slot on the bottom edge of the transmitter housing, tie a knot in the wire just inside the housing to act as a strain relief, and secure the wire ends to the terminal block as illustrated in Figure 2.
  7. Reverse the steps shown in Figure 1 to reinstall the transmitter housing on its mounting base.

Refer to the WRZ-STRxxxx-2 Series Wireless Refrigerator or Freezer Temperature Transmitterand Probe Assemblies Installation Instructions (Part No. 24-10332-10) for information on how to prepare the transmitter for operation.
