After all debris has been removed from the system, replace the cover onto the unit being
careful not to pinch or damage the wiring connecting the cover to the base.
Another part of the system which may need cleaned occasionally is the cooling system
cabinet. To clean the system cabinet, simply wipe it with a damp, lint free cloth. A mild
soap solution may be used if necessary.
Trouble Shooting
If your air conditioning system should fail to operate satisfactorily during the first
year of operation, do not remove the cover without first notifying the factory. Removal of
the cover will immediately void your warranty. If an operating problem should occur,
please make the following simple checks before contacting DDB.
*
Is
electrical power available at the outlet?
* Is the power cord plugged into the outlet?
* Is the controller set point temperature above the enclosure temperature?
* Is the evaporator (cold air stream) blower operating?
* Is the compressor and condenser (warm air stream) blower operating?
* Is the enclosure door closed tightly?
* Are all gaskets in place?
* Are there any unusual ambient conditions?
* Has the warm air filter been cleaned or changed recently?
* Is the system mounted level on the enclosure?
* Is there adequate space within the enclosure for air flow?
* Is there adequate space around the enclosure for air flow?
* Have you recently added electronic equipment to the enclosure?
If you are still experiencing operating difficulties after making these checks, please
contact DDB at 800-753-8459.
