1. BEFORE YOU BEGIN
1.1 PRODUCT DESCRIPTION
Our powerful portable air conditioners are great cooling solutions for
single rooms, creating a comfortable atmosphere in your space. It also
has ventilation and dehumidifying functions for circulating air and removal
of moisture. They're self-contained systems that do not require any
permanent installation allowing you to move to the space in which it is
most needed. They're commonly used in kitchens, temporary-resided,
computer rooms, garages, and many other places where installation of
Air-conditioner Outdoor unites is limited.
The environmentally friendly R32 is used as the refrigerant. R32 has no
damaging influence on the ozone layer (ODP), a negligible greenhouse
effect (GWP) and is available worldwide. Because of its efficient energy
properties, R32 is highly suitable as a coolant for this application. Special
precautions must be taken into consideration due to the coolant's high
flammability.

2.2.6 No ignition sources
No person carrying out work concerning a refrigeration system that
involves exposing any pipe work that contains or has contained flammable
refrigerant shall use any sources of ignition in such a manner that it may
lead to the risk of fire or explosion. All possible ignition sources, including
cigarette smoking, should be kept sufficiently far away from the site of
installation, repair, removal, and disposal, during which flammable
refrigerant can be released into the surrounding space. Prior to work
taking place, the area around the equipment is to be surveyed to make
sure that there are no flammable hazards or ignition risks. “No Smoking”
signs shall be displayed.
2.2.7 Ventilated area
Ensure that the area is in the open or that it is adequately ventilated
before breaking into the system or conducting any hot work. A degree of
ventilation shall continue during the period that the work is carried out.

– The charge size is in accordance with the room size within which the
refrigerant-containing parts are installed;
– The ventilation machinery and outlets are operating adequately and are
not obstructed;
– If an indirect refrigerating circuit is being used, the secondary circuit
shall be checked for the presence of refrigerant;
– Marking to the equipment continues to be visible and legible. Markings
and signs that are illegible shall be corrected.
12
– Refrigeration pipes or components are installed in a position where they
are unlikely to be exposed to any substance which may corrode
refrigerant-containing components unless the components are constructed
of materials that are inherently resistant to being corroded or are suitably
protected against being so corroded.
2.2.9 Checks to electrical devices
Repair and maintenance of electrical components shall include initial
safety checks and component inspection procedures. If a fault exists that
could compromise the safety, then no electrical supply shall be connected
to the circuit until it is satisfactorily dealt with. If the fault cannot be
corrected immediately but it is necessary to continue operation, an
adequate temporary solution shall be used. This shall be reported to the
owner of the equipment so all parties are advised.
Initial safety checks shall include:
-those capacitors are discharged: this shall be done in a safe manner to
avoid the possibility of sparking;
-that there are no live electrical components and wiring that are exposed
while charging, recovering, or purging the system;
-that there is continuity of ground bonding.

plug.
Notes: Please move the machine carefully, so as not to spill the water in the
water pan at the bottom of the body.
2）Place the water container below the side water outlet behind the body.
3）Unplug the water plug, the water will automatically flow into the water
container.
Notes:
1. Keep the water plug properly closed tight.
2. During drainage, the body can be tilted slightly backwards.
3. If the water container cannot hold all the water before the water container is
full, plug the water outlet with the water plug as soon as possible to prevent
water from flowing to the floor or the carpet.
4）When the water is discharged, stuff the water plug.
Notes: 1. Restart the machine after the water plug and drainage cover are
installed, otherwise the water inside the machine will flow to the floor or the
carpet.
28
Continuous drainage
The self-evaporating system uses the collected water to cool the
condenser coils for better efficient performance. There is no need to
empty the drainage tank in cooling operation except in drying operation
and high humidity conditions. The condensation water evaporates at
the condenser and is evacuated through the exhaust hose.
For continuous operation or unattended operating in drying operation,
please connect the attached drain hose to the unit. Condensation water
can automatically flow into a bucket or drain by gravity.
Switch off the unit before
operating.
Remove the plug of the water
outlet opening and keep it in safe
area.
Securely and properly connect
the drain hose and make sure it
is not kinked and clear of
obstruction.
Place the outlet of hose over a
drain or bucket and ensure that
water could freely flow out of the
unit.
Do not submerge the end of hose
into water; otherwise it can cause
"Air Lock" in the hose.
To avoid water spillage:
• As the negative pressure of condensation drain pan is large, tilt the
drain hose downward toward the floor. It is appropriate that the
degree of inclination should exceed 20 degrees.
• Straighten the hose to avoid a trap existing in the hose.
