Specific Performance Issues | WhisperKool XLT 4200, XLT 8000, XLT 3000

Specific Performance Issues:

Unit is Not Cooling Sufficiently or Not Cooling at All:

19) On a thermostat with digital readout, what is the set temperature? To check, hold down the	Yes
“SET” button on the thermostat to see the set temperature. Refer to page 15 - 16 of the owner’s
manual.
20) What is the actual temperature of the cellar?	Yes

*To check air temperature, use a digital thermostat which can be purchased at any hardware store under kitchen supplies.

21) On a thermostat with digital readout, does the thermostat display two horizontal dashes or	Yes
the letters “PRB”? (This indicates a problem with the thermostat.)
22) Is the probe inserted into a bottle of water? Refer to page 14 of the owner’s manual.	Yes

Water is Leaking from the Unit:

All units come with a drain line for additional removal of excess condensate, as a back up system to the Condensate Evaporator which is used to maintain proper humidity. It is critical to install the drain line attachment for the unit to function effectively, preventing overflows and leaks from build up of condensate. See page 13.

Failure to install drain line will void warranty.

23) Is the unit level?	Yes
24) Is the drain line attached?	Yes
25) Is the unit leaking from the back?	Yes
This is generally due to an improper setting on the condensate evaporator. In high humidity
regions, the condensate evaporator should be set to “ON” while other regions should be set to
“AUTO”. Refer to page 13 of the owner’s manual.
Unit is Icing Up:
26) Is the unit icing up? Allow the unit to thaw for 24-36 hours and ensure that there is adequate	Yes
airflow to and from the unit before operating again. Obstructed airflow is a possible reason
why units ice up. Make sure coils are clean and the probe in inserted in the bottle. Refer to page
22 of the owner’s manual.
Unit Short Cycles, Clicks Intermittently, Trips Breaker, or does not Run:
27) Is there power being supplied to the outlet? To check, test the outlet using a small appliance	Yes
(hairdryer).
28) Is the unit on a GFI (Ground Fault Interrupter)? The unit should not be run on a GFI. Refer to	Yes
page 10 of the owner’s manual.
29) Does the unit have a dedicated electrical line and 20 amp circuit breaker? To check, examine	Yes
the breaker box to see if the cellar is on its own circuit. Refer to page 22 of the owner’s manual.
30) Are there any large appliances plugged into the same room or in the same area of the building	Yes
of the cooling unit? Refer to page 22 of the owner’s manual.
