Description
Unpacking
Specifications
Weltem Portable Air Conditioners feature spot cooling for large areas
where cooling of the entire area is not practical. A dedicated
spot cooling thermostat controls the unit in this application.
These air conditioners can also be used in smaller areas
for room cooling.
A control panel provides ease of use and contains a self-diagnostic
function and display, showing operating modes, room and
set temperatures, and faults.
If an abnormal operation occurs, a visual display of the fault is shown.
Caster wheels are included for easy portability.
Suitable applications include: a factory or work place, industrial kitchen,
computer room, emergency cooling, outdoor event, etc.

guard in the closed position.
5. Replace the clean filter and close the filter guard.
6. To clean the condenser filter, lift up on the side filter from the middle bar slightly and then angle the filter outwards
from the bottom and remove.
7.Use the same cleaning procedure as above (3 – 5).
8. To replace the condenser filter, place the top of the filter in the guide and slide the filter up until the bottom of the
filter clears the frame.
Then push the bottom of filter into the guide and let filter gently fall inside the guide.
NOTE: For effective cooling clean the filter at least every 2 weeks.
– For your convenience, record the complete model number and product name (located on the Product
