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 function 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 Unit 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.
1.2 SYMBOLS FROM THE UNIT AND USER MANUAL
warning
This unit uses a flammable refrigerant.
If refrigerant leaks and comes in contact with a fire or
heating part, it will create harmful gas and there is a risk of
fire.
Read the USER MANUAL carefully before operation.

2.2 SAFETY PRECAUTIONS ON SERVICING
Please follow these warnings when to undertake the following when
servicing an appliance with R32.
2.2.1 Checks to the area
Prior to beginning work on systems containing flammable refrigerants,
safety checks are necessary to ensure that the risk of ignition is minimized.
For repair to the refrigerating system, the following precautions shall be
complied with prior to conducting work on the system.
2.2.2 Work procedure
Work shall be undertaken under a controlled procedure so as to minimize
the risk of flammable gas or vapor being present while the work is being
performed.
2.2.3 General work area
All maintenance staff and others working in the local area shall be
instructed on the nature of work being carried out. Work in confined
spaces shall be avoided. The area around the work space shall be
sectioned off. Ensure that the conditions within the area have been made
safe by control of flammable material.
2.2.4 Checking for presence of refrigerant
The area shall be checked with an appropriate refrigerant detector prior to
and during work, to ensure the technician is aware of potentially
flammable atmospheres. Ensure that the leak detection equipment being
used is suitable for use with flammable refrigerants, i.e. no sparking,
adequately sealed or intrinsically safe.
2.2.5 Presence of fire extinguisher
If any hot work is to be conducted on the refrigeration equipment or any
associated parts, appropriate fire extinguishing equipment shall be
available to hand. Have a dry powder or CO2 fire extinguisher adjacent to
the charging area.
