Please read and save these instructions. Read carefully before attempting to assemble, install, oper-
ate or maintain the product described.
Protect yourself and others by observing all safety information. Failure to comply with instructions
could result in personal injury and / or property damage! Retain instructions for future reference.
Weltem Portable Air Condioners feature spot cooling for large
areas where cooling of the enre area is not praccal. A dedi-
cated 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 oc-
curs, 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, outdoor event,
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.

14. DO NOT use the plug to start and to stop the unit. Always use the control panel to start and
to stop the unit.
15. Always turn o the unit when it is not in use and unplug the power plug from the electrical
outlet.
16. Always turn the unit o and unplug the main power plug from the electrical outlet before
cleaning, moving or performing maintenance.
17. AVOID the use of adapter plugs or extension cords. If it is necessary to use an extension cord
or an adapter plug to operate the unit, ensure that they are correctly rated for the applica-
on. Consult a local qualied lectrician and all local electrical codes to ensure proper setup.
Any extension cord used with this device must be rated for a minimum of 10A, 250V.
18. DO NOT unplug the unit by pulling on the electrical cord. Keep electrical cord away from heat
sources and always completely unroll the cord to avoid overheang. If the power cord be-
comes damaged, a qualied service agent, qualied electrician, or similarly qualied person

ing, always ensure that the unit has been turned o and unplugged from the electrical outlet.
20. Regularly clean the lters to maintain eciency. If the lters are not cleaned regularly, the
units output performance and eciency will decline and energy consumpon will increase.
21. DO NOT operate the unit with a damaged power cord or plug, aer it malfuncons, has been
dropped or damaged.
22. Only use in the upright posion on an even, at surface. Unit must be posioned at least 24

order to change °C to ° F, press SPOT/COOL and ROOM/COOL buons together for 2 seconds.
F will blink 2 mes and Figure will change to °F. 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 for1 seconds. Press UP/DOWN Buon to set the mer unl it shows the gure you want

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 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.
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.
