Appendices (Cont'd)

1.1The following recommendations are made for the purpose of arriving at easily taken and understood data which, coupled with other observations, may be used to determine whether a display refrigerator is working as intended:

a)INSTRUMENT - A stainless steel stem-type thermometer is recommended and it should have a dial a minimum of 1 inch internal diameter. A test thermometer scaled only in Celsius or dually scaled in Celsius and Fahrenheit shall be accurate to 1°C (1.8°F). Temperature measuring devices that are scaled only in Fahrenheit shall be accurate to 2°F. The thermometer should be checked for proper calibration. (It should read 32°F when the stem is immersed in an ice water bath).

b)LOCATION - The probe or sensing element of the thermometer should be located in the airstream where the air first enters the display or storage area, and not more than 1 inch away from the surface and in the center of the discharge opening.

c)READING - It should first be determined that the refrigerator is refrigerating and has operated at least one hour since the end of the last defrost period. The thermometer reading should be made only after it has been allowed to stabilize, i.e., maintain a constant reading.

d)OTHER OBSERVATIONS - Other observations should be made which may indicate operating problems, such as unsatisfactory product, feel/appearance.

e)CONCLUSIONS - In the absence of any apparent undesirable conditions, the refrigerator should be judged to be operating properly. If it is determined that such condition is undesirable, i.e., the product is above proper temperature, checks should be made for the following:

1.Has the refrigerator been loaded with warm product?

2.Is the product loaded beyond the “Safe Load Line” markers?

3.Are the return air ducts blocked?

4.Are the entering air ducts blocked?

5.Is a dumped display causing turbulent air flow and mixing with room air?

6.Are spotlights or other high intensity lighting directed onto the product?

7.Are there unusual draft conditions (from heating/air-conditioning ducts, open doors, etc.)?

8.Is there exposure to direct sunlight?

9.Are display signs blocking or diverting airflow?

10.Are the coils of the refrigerator iced up?

11.Is the store ambient over 75°F, 55% RH as set forth in ASHRAE Standard 72 and ASHRAE Standard 117?

12.Are the shelf positions, number, and size other than recommended by Hussmann?

13.Is there an improper application or control system?

14.Is the evaporator fan motor/blade inoperative?

15.Is the defrost time excessive?

16.Is the defrost termination, thermostat (if used) set too high?

17.Are the refrigerant controls incorrectly adjusted?

18.Is the air entering the condenser above design conditions? Are the condenser fins clear of dirt, dust, etc.?

19.Is there a shortage of refrigerant?

20.Has the equipment been modified to use replacements for CFC-12, CFC-502 or other refrigerant? If so, have the modifications been made in accordance with the recommendations of the equipment manufacturer? Is the refrigerator charged with the proper refrigerant and lubricant? Does the system use the recommended compressor?

Appendix D. - Recommendations to User

1.0Hussmann Corporation provides instructions and recommendations for proper periodic cleaning. The user will be responsible for such cleaning, including the cleaning of low temperature equipment within the compartment and the cooling coil area(s). Cleaning practices, particularly with respect to proper refrigerator unloading and warm-up, must be in accordance with applicable recommendations.
