After completing the temperature differential test, determine if the unit is not cooling at all or if it is 

not cooling enough.
If the unit is not cooling at all, contact WhisperKOOL Customer Service at 800.343.9463. Be sure to have 

the measurements and results from your Temperature Differential test available. 

If the unit is cooling but not cooling fully (with a evaporator differential of 10°F-15°F and a condenser 

differential of approximately 30°F), it indicates that there is too much heat on the back side of the unit. 

In this case, you should:

• Check to make sure that there is at least 3’ of unobstructed space in front of the fans/vents to allow 

adequate ventilation. Improper ventilation causes the majority of problems with cooling units.

• On the condenser side, if the inlet air temperature is >90°F and/or the outlet air temperature is 

>120°F, there is too much heat on the back side of the unit which is preventing it from cooling 

fully. To remedy this, heat needs to be dissipated away from the unit through an exhaust fan or 

other means of ventilation on the exhaust side. You can contact Vinothèque Customer Service to 

request a ducting flange adapter at no charge to assist in directing heat away from the unit (for 

warranty units only).

• You might consider installing a WhisperKOOL approved ventilation ducting system for your unit 

which can be obtained through WhisperKOOL Customer Service.

• Contact WhisperKOOL Customer Service at 800.343.9463. Be sure to have the measurements and 

results from your Temperature Differential test available.
