Weltem Portable Air Condi oners feature spot cooling for
large areas where cooling of the en re area is not prac cal.
A dedicated spot cooling thermostat controls the unit in this
applica on.
These air condi oners can also be used in smaller areas for
room cooling.
A control panel provides ease of use and contains a self-diag-
nos c func on and display, showing opera ng modes, room
and set temperatures, and faults.
If an abnormal opera on occurs, a visual display of the fault is
shown. Caster wheels are included for easy portability. Suitable
applica ons include: a factory or work place, computer room,
emergency cooling, etc.
A er unpacking the unit, carefully inspect unit for any damage that may have occurred during
transit. Check for any loose, missing, or damaged parts.

FILTER CLEANING (See Figures 9 and 10)
There are two lters in the unit. The evaporator lter is located at the front of the unit. The
condenser lter is located at the side of the unit.
1. loosen up 2 bolts on the front lter guard.
2. Slide lter up and use a vacuum cleaner to remove the dust from the lter.
3. If the lter is heavily covered with dust and dirt, warm water and mild soap or neutral deter-
gent may be used to wash the lter. Do not use any other chemicals to clean lter, as they will
likely damage the lter.
4. Dry the lter in a shaded area before replacing it. Do not operate the unit without the lter
installed and the lter guard in the closed posion.
5. Replace the clean lter and close the lter guard.
6. To clean the condenser lter, li up on the side lter from the middle bar slightly and then
angle the lter outwards from the boom and remove.
7.Use the same cleaning procedure as above (3 – 5).
8. To replace the condenser lter, place the top of the lter in the guide and slide the lter up
unl the boom of the lter clears the frame. Then push the boom of lter into the guide
and let lter gently fall inside the guide.
NOTE: For eecve cooling clean the lter at least every 2 weeks.

SPRING REPLACEMENT (See Figure 11)
SELF-DIAGNOSTIC CODES (See Table 1)
The alarm light is acvated if abnormal operaon occurs, and a code is displayed on the control
panel. The compressor and condenser fan motor will stop operang. The evaporator fan will
connue to run for 3 minutes. If the fault is reced within 3 minutes, the unit will resume oper-
aon. If the fault persists for more than 3 minutes, the evaporator fan also stops. The fault must
be reced before the unit can resume normal operaon.
There are two springs on the rear of condensate water tank guide.
1. Release the screw on the spring hook.
2. Take o the spring hook, and then pull out the opposite spring
hook from hole in the condensate water tank guide.
3. Replace with a new spring in reverse order.
4. Repeat this cycle for the other spring.
