Mechanical Components

EVAPORATOR COIL & EXPANSION VALVE

The evaporator coil is located in the bottom of the case under the deck pans. The 

thermostatic expansion valve (TXV) is typically located at the end of the evaporator 

coil. The TXV is not preset, and superheat should be adjusted to 6-8°F. Contact 

Zero Zone for superheat setting if using high-glide refrigerants.

To adjust the TXV, remove the far right deck pan (

See Figure 36

). Remove the cap 

from the bottom of the TXV. When looking at the valve stem end, turn the valve 

stem counterclockwise to decrease superheat. Turn the valve stem clockwise to 

increase superheat. Measure the suction line temperature at the TXV sensing bulb 

and compare it to the suction temperature corresponding to the saturated pressure. 

Make sure that line pressure drop is taken into account. Turn the valve stem only 

1/4 turn at a time and allow sufficient time (20 to 30 minutes) for the TXV to settle 

before making further adjustments. After the superheat has been adjusted, wipe the 

valve stem cap dry and screw it back on.

EVAPORATOR FANS

Air is circulated through the display case by fans, which are located below the deck pans in the bottom of the case (

See Figure 37

). Air is drawn 

through the front return air grill and discharged out of the honeycomb at the top. The fan motors must be operating at all times. Fan motors 

should be replaced with motors having the same characteristics including type, physical size, lubricant temperature range, wattage, and RpM. 

Fan blades should be replaced with OEM parts or have the same fan pitch as the OEM fan blade.

! 

CAUTION! 

 

DISCONNECT pOWER TO THE CASE BEFORE SERVICING ELECTRICAL 

COMpONENTS TO AVOID pERSONAL INJURY AND DAMAGE TO THE UNIT.

1.  Disconnect power to the fan.
2.  Remove the fan blade nut and fan blade.
3.  Remove the mounting bolts and remove the fan assembly from the fan housing.
4.  Remove the fan motor mounting screws from the back of the fan motor.
5.  Replace the fan, and reverse steps 1-3 to install the cover. Restore case power.

Refrigerant piping

Unless otherwise specified, the liquid and suction connections terminate inside the case under the coil 

cover. Refrigerant piping may enter the case through the left rear back panel or the left rear top panel of 

the case. Other exit options are available. The copper pipe should not touch or rub on the edges of the 

sheet metal.

Correct refrigeration line sizing and industry standard installation practices are essential for proper 

system operation. Zero Zone offers many refrigerant choices. We recommend using the Sporlan Virtual 

Engineer Toolbox to calculate sizing for liquid, suction, and discharge lines: 

https://solutions.parker.com/

sporlanvirtualengineer

. Go to the link, select the line type, and then enter the information required to 

calculate the recommended line size. Toggle between metric or imperial units as needed.

After connections have been made, the refrigeration access holes or penetrations in the case must be 

sealed completely with an aerosol-dispensed urethane insulation or equivalent (example: Great Stuff).
