AmeriCool by Weltem Portable Air Condioners feature spot cool-
ing for large areas where cooling of the enre area is not praccal.
A dedicated spot cooling thermostat controls the unit in this ap-
plica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-diagnos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,
industrial kitchen, 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.

10 by pressing connually. Press the SET TEMP BUTTONS to set temperature. Upper buon is
to heighten temperature and Lower buon is to lower temperture.
6. ALARM: Alarm indicator lights (blinks) and indicates abnormal system operaon. If Alarm oc-
curs, compressor stops. System operaon stops when ALARM light is acvated (blinks) longer
than 3 minutes.
7. CURRENT TEMP: Displays current room temperature in display in Fahrenheit. (In Room Cool
Mode only). SPOT/COOL Mode – Displays outlet (cool air) temperature during normal opera-
ons. In order to change °F to °C, press SPOT/COOL and ROOM/COOL buons together for 2
seconds. C will blink 2 mes and Figure will change to °C. ALARM codes blink and are displayed
when abnormal operaon occurs.
8. TARGET TEMP: displays the unit set temperature for ROOM/COOL mode only.
OFF-TIMER: Enter to Timer Seng Mode if you press BLOWER Buon and SPOT/COOL Buon
together for 1 seconds. Press UP/DOWN Buon to set the mer unl it shows the gure you

FILTER CLEANING (See Figures 10 and 11)
There are three lters in the unit. The evaporator lter is located at the front of the unit. The
condenser lters are 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 lters, li up on the side lters from the middle bar slightly and then
angle the lters 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.

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 opera-
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.
