The sensing bulb is located under the coil cover on the back side of the fan shroud. It can be wired in series with the low-pressure (L.P.) control. It can also be used in a pump down system by wiring it in series with the liquid solenoid valve.

    There are many control options available for multiple case defrost systems. Wiring diagrams and instructions can be obtained by contacting Zero Zone’s Service Department. External wiring should be sized according to the amperage rating stamped on the serial plate. The serial plate is located on the ceiling inside the left-hand door.
  • Page 34 ELECTRICAL GENERAL (CONT.) Single Point Connection (Medium Temp) The “single point” connection system is designed to reduce the time required to install and wire one display case with one condensing unit. Figure 31 on page 37 is a typical diagram for this system. All of the display case controls, including the disconnect switch and electronic case controls, are installed behind the kickplate and prewired.
  • Page 35 ELECTRICAL GENERAL (CONT.) Master Satellite Connection (Medium Temp) The “master satellite” connection system allows one condensing unit to be connected to multiple cases. Figure 32 on page 38 shows a typical diagram for this system. All of the display case controls, including the disconnect switch, time clock, and temperature control, are installed behind the kickplate and prewired.

    Unless the installer rewires the defrost thermostat, the defrost heater is de-energized when defrosting is complete. Electric Defrost Zero Zone VZ and VZT2 30" door electric defrost freezers are also equipped with a high-limit, snap-disc thermostat that de-energizes Frequency: One electric defrost per day is recommended.
  • Page 44 Sizing and component selection depend on the type of defrost, size, and location of high side refrigeration system. Zero Zone freezers equipped for gas defrost consist of a side port distributor and a TXV check valve for coil defrost, and a suction line check valve to bypass hot gas to the serpentine coil.

  • Page 48: Medium Temp

    DEFROSTING MEDIUM TEMP GENERAL Periodic defrosting to keep the coil free of frost is accomplished automatically by a time clock. Medium temperature cases generally operate at temperatures that allow for off-cycle defrost. Medium temperature cases that operated at colder temperatures for fresh meat products may use electric or hot gas defrost.
