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.
AmeriCool by Weltem Portable Heat Pump feature spot
cooling/hea ng for large areas where cooling/hea ng of the
en re area is not prac cal. A dedicated spot cooling/hea ng
thermostat controls the unit in this applica on.
This unit can also be used in smaller areas for room cooling/
hea ng. 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, indus-
trial kitchen, computer room, emergency cooling/hea ng,
outdoor event, supplement cooling / hea ng 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.

General Safety Informaon
Please read this manual carefully for instrucons on correct installaon and usage. Please read
all safeguards.
1. Transport and store the unit in an upright posion only. Leave unit in an upright posion for at
least 3 hours before rst use.
2. Always place the unit on an even, level surface.
3. Ensure the unit is connected to a grounded power supply of the correct rang / capacity.
4. The unit will cool when the room temperature is between 18°C (64°F) ~ 45°C(113°F) and heat
when the room temperature is between 12°C(56°F ) ~ 27°C(80°F), depending on the thermo-
stat seng.
5. DO NOT use this unit for funcons other than those described in this instrucon manual.
6. DO NOT lt the unit.
7. DO NOT cover or obstruct the unit’s inlet and outlet grilles.
8. DO NOT use the unit in areas where it will be exposed to rain or water.
9. NEVER unplug the unit while it is operang.
DO NOT use the unit in wet environments, such as a laundry room, to avoid
the risk of electrical shock.
DO NOT operate the unit in explosive or ammable environments.
10. DO NOT place any foreign objects on the unit.
11. DO NOT operate the unit with wet or damp hands.
12. DO NOT allow chemical substances to come into contact with the unit.
13. DO NOT operate the unit in the presence of ammable substances or vapors such as alcohols,
pescides, gasoline, etc.
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 20A.(120V)
18. DO NOT unplug the unit by pulling on the electrical cord. Keep electrical cord away from heat

FILTER CLEANING (See Figures 10 and 11)
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 back of the unit.
1. Pull the lter frame forward to remove the front lter.
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 rear 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 12)
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.
