Conclusions
After completing the temperature dierential 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 Dierential test available.
If the unit is cooling but not cooling fully (with a evaporator dierential of 10°F-15°F and a condenser
dierential 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 ange 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 Dierential test available.
