this user manual before using the product,
including safety warnings, and any
assembly and operating instructions.
Keep the manual for future reference.
Safety precautions and recommendations
detailed here must be fully understood
and followed to reduce the risk of injury,
fire, explosion, electrical hazard, and/or
property damage.
Safety information presented here is
generic in nature – some advice may not
be applicable to every product. The term
"equipment" refers to the product, be it
electrical mains powered, battery powered
or combustion engine powered.
• Before Use - If you are not familiar with
the safe operation/handling of the
equipment, or are in any way unsure of
any aspect of suitability or correct use
for your application, you should
complete training conducted by a
person or organization qualified in safe
use and operation of this equipment,
including fuel/electrical handling and
safety.
• Do NOT operate the equipment in
flammable or explosive environments,
such as in the presence of flammable
liquids, gases or dust. The equipment
may create sparks or heat that may
ignite flammable substances.
• Keep clear of moving parts.
• Equipment may be a potential source of
electric shock or injury if misused.
• Do NOT operate the equipment if it is
damaged, malfunctioning or is in an
excessively worn state.

Assembly and Set-Up
Leave the mobile air-conditioner in an upright position for at least 2 hours before first use.
This air-conditioner may be moved indoor conveniently; leave the air-conditioner in an upright position
while moving it. The air-conditioner should be placed on a flat, stable surface. Do not install or operate
this air-conditioner in a bathroom or other wet environments.

1. Take out the C-shape buckle of the heat exhaust hose and remove the plastic bag.
2. Point the rotary hole at the end of the heat exhaust hose snap toward the rotation shaft of the back
shell and slide it onto the back shell in accordance with the snap joint direction of the rotation shaft
on the back shell (as shown in the figure above).
NOTE: When the end snap joint at the end of the rotation shaft of the back shell sticks out, it means
that the heat exhaust hose snap has been positioned into place.
3. Rotate the C-shape buckle of the heat exhaust hose that was positioned into place anti-clockwise
to clip the snap joint of the C-shape buckle of the back shell successfully through the guide of the
slide way of the back shell (as shown in the right part of the figure above).

Installation of the Heat Exhaust Hose Assembly and Unit
1. Pull the end of the heat exhaust hose apart by several turns.
2. Hold the end handle of the C-shape buckle of the heat exhaust hose with the left hand and the heat
exhaust hose short connector with the right hand, put one end of the heat exhaust hose that is
pulled apart onto the snap of the lower air duct bottom, press the C-shape buckle of the heat
exhaust hose with the left hand by force so that the C-shape buckle of the heat exhaust hose clips
the snap joint of the back shell (as shown in the right part of the figure above).
NOTE: The end of the heat exhaust hose must reach one step inside the bottom of the lower air
duct (as shown in the figure above).
3. The few turns at the end of the heat exhaust hose must be snapped in the snap of the lower air duct
bottom.
4. The C-shape buckle that clips the heat exhaust hose must clip the back shell and heat exhaust
hose firmly.
5. Hold the unit with one hand and the heat exhaust hose short connector with another hand; or both
people cooperate with one person holding the unit and the other person pulling the heat exhaust
hose to prolong the heat exhaust hose gently.

sealing board assembly (as shown in the figures above).
NOTE: • The flat end of the heat exhaust hose short connector must be snapped into
place. • The heat exhaust hose should not be bent and should be free from significant
bending (greater than 45°), and the heat exhaust hose must be ventilated properly. • The
exhaust hose is 270-1500mm long and this length is determined based on the specification of the
unit. Do not overextend the hose or replace it with other different hoses as this may affect the
functions of the air-conditioner. The exhaust pipe must be as straight as possible; air-conditioner
may overheat if the exhaust pipe is obstructed.
