1. BEFORE YOU BEGIN
1.1 PRODUCT DESCRIPTION
Our powerful portable air conditioners are great cooling solutions for
creating a comfortable atmosphere in your space. It also features
ventilation and dehumidifying functions for circulating air and the removal
of moisture. They are self-contained systems that do not require any
permanent installation allowing you to move to the space in which it is
most needed. They are commonly used in kitchens, computer rooms,
garages, and many other areas where installation of an Air-conditioner
Outdoor Unit is limited.
The environmentally friendly R290 is used as the refrigerant. R290 has no
damaging influence on the ozone layer (ODP), a negligible greenhouse
effect (GWP) and is available worldwide. Because of its efficient energy
properties, R290 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 SAFETY PRECAUTIONS ON SERVICING

10
Please follow these warnings when to undertake the following when
servicing an appliance with R290.
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 a 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 workspace 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.

11
2.2.6 No ignition sources
No person carrying out work in relation to a refrigeration system which
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, repairing, removing and disposal, during which flammable
refrigerant can possibly be released to 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 ventilation should safely disperse any released refrigerant and
preferably expel it externally into the atmosphere.
2.2.8 Checks to the refrigeration equipment
Where electrical components are being changed, they shall be fit for the
purpose and to the correct specification. At all times the manufacturer’s
maintenance and service guidelines shall be followed. If in doubt consult
the manufacturer’s technical department for assistance.
The following checks shall be applied to installations using flammable
refrigerants:
– 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;

12
– 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;
– refrigeration pipe 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 which are inherently resistant to being corroded
or are suitably protected against being so corroded.
2.2.9 Checks to electrical devices
Repair and maintenance to electrical components shall include initial
safety checks and component inspection procedures. If a fault exists that
could compromise 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 possibility of sparking;
- that there no live electrical components and wiring are exposed while
charging, recovering or purging the system;
- that there is continuity of earth bonding.
WARNING!
Install the unit in rooms which exceed 10 m².
Do not install the unit in a place where inflammable gas
may leak.
