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 dedicated spot cool-
ing 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-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 in-
clude: a factory or work place, industrial kitchen, computer room, emer-
gency 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.

InstallaƟon
MOVING THE UNIT
PLUGGING IN THE UNIT
Unlock the casters and push the unit using the side handles to a flat, level surface and set the
caster brakes to the locked posion.
Check the prongs and surface of the power cord plug for dust/dirt. If dust and/or dirt are pres-
ent, wipe offwith a clean, dry cloth.
Check the power cord, plug and prongs for damage or excess play.
If any damage or excess play is found, contact a qualified repair technician or a qualified electri-
cian to perform replacement or repair of the power cord, plug or prongs.
NOTE: Make sure the AC outlet is free of dirt, dust, oil, water, or any other foreign material. The
unit is equipped with an approved NEMA plug configuraon (WPC-7000: 6-20P / WPC-
9000:6-30P). The appropriate outlet must be used for each plug type.
WARNINGS REGARDING PROPER LOCATION FOR INSTALLATION
Do not use the unit in explosive environments or in areas where flammable
gas leakage may occur.
Do not use the unit in areas where it will be exposed to rain or water.
Do not use the unit in a corrosive atmosphere.
Do not use the unit above 18°C(64°F) ~ 45°C(113°F).
Do not install the unit on uneven or sloping surface. The unit may roll or
topple over even if the casters are set to the locked posiƟon.
If the power cord or plug is damaged, repair should only be performed by
qualified electrical personnel.
Do not connect / disconnect the power cord or aƩempt to operate buƩons
with wet hands. This could result in electrical shock.
An ambient air adapter can be purchased separately. Air adapter fits over
the condenser to duct condenser air to the unit to improve cooling ef-
ficiency.
1. Remove air adapter from carton.
2. Place air adapter on the rear of air condioner.
3. Use screws (enclosed inside of box with air adapter) to install the adapter
on the air condioner as shown in Figure 6.

OperaƟon
CONTROL PANEL
1. POWER BUTTON: Acvates unit when POWER BUTTON is pressed. (Fan starts on low speed). If
power buon is pressed during operaon, unit stops.
2. BLOWER BUTTON: Changes fan speed from (Low) to (High) when pressed.
3. SPOT/COOL BUTTON: Acvates compressor and begins producing cool air 5 seconds aer but-
ton is pressed. Regulates temperature based on outlet cool air temperature.
4. ROOM/COOL BUTTON: Acvates compressor and produces cool air 5 seconds aer buon is
pressed. Regulates temperature based on inlet ambient air temperature.
5. SET TEMP BUTTONS: Change target temperature/data value by +/- 1. Change data value by +/-
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.
NOTE: Canadian version shows the temperature in Celsius first when you turn on the unit.
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 figure you want
to set. Aer 5 seconds,the figure will be memorized and the compressor will stop aer the me set.
AUTO RESTART: If the unit goes offdue to an electrical interrupon, the unit will automacally
restart when the power resumes.

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

SPRING REPLACEMENT (See Figure 10)
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fied 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fied 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 offthe 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.
