♦
Is clear of direct sunlight, high temperature sources, and heating and air conditioning vents.
♦
Minimum 8“ (203 mm) above, and minimum 3” (76 mm) behind.

2.2 Placement and Leveling
CAUTIONS
• The evaporation tray located on the rear of the refrigerator may be hot. Do not use the tray as a handle.
• To prevent tipping, ensure the casters are unlocked, leveling feet (if installed) are lifted, and the doors are closed before
moving the refrigerator.
1. Roll refrigerator into place and lock casters.
2. Ensure refrigerator is level.
Note
Helmer recommends the use of leveling feet.
2.3 Temperature Probes
Probe bottle(s) along with a container of glycerin have been provided with this unit. The glycerin is used to create a solution which
simulates the product stored in the refrigerator. The product simulation solution temperature reflects the product’s temperature
during normal operation.
Notes
• Temperature probes are fragile; handle with care.
• Number and location of probes varies by model.
• Remote probes may also be introduced through the existing top port or through the side port (if included).
CAUTION
Failure to fill probe bottles or keep probe bottles filled to the appropriate level may not allow the chamber temperature to
stabilize at the refrigerator setpoint or the chamber temperature to display higher or lower than the actual temperature.
Primary Monitor Probe
The primary monitor probe is located in the top right corner of the refrigerator.
