Safety precautions
Prevent water leakage by ensuring drainage
pipe is:
- Connected properly,
- Kept clear of gutters and containers, or
- Not immersed in water
After a long period of use or use with any
combustible equipment, aerate the room
regularly.
After a long period of use, make sure the
installation rack does not deteriorate to prevent
the unit from falling down.
Remote control
Do not use rechargeable (Ni-Cd) batteries. It
may damage the remote control.
To prevent malfunction or damage of the remote
control:
• Remove the batteries if the unit is not going to
be used for a long period of time.
• New batteries of the same type must be
inserted following the polarity stated.
Power supply
Do not disconnect the plug by pulling the cord to
prevent electric shock.
nanoe-G generator
Do not touch the sharp pin which may cause
injury.
Precaution for using R32 refrigerant
The basic installation work procedures are the same as
conventional refrigerant (R410A, R22) models.
1. Installation (Space)
• Must ensure the installation of pipe-work shall
be kept to a minimum. Avoid use dented pipe
and do not allow acute bending.
• Must ensure that pipe-work shall be protected
from physical damage.
• Must comply with national gas regulations,
state municipal rules and legislation. Notify
relevant authorities in accordance with all
applicable regulations.
• Must ensure mechanical connections be
accessible for maintenance purposes.
• In cases that require mechanical ventilation,
ventilation openings shall be kept clear of
obstruction.
• When disposal of the product, do follow to the
precautions in #12 and comply with national
regulations.
Always contact to local municipal offi ces for
proper handling.

2. Servicing
2-1. Service personnel
• Any qualifi ed person who is involved with
working on or breaking into a refrigerant circuit
should hold a current valid certifi cate from
an industry-accredited assessment authority,
which authorizes their competence to handle
refrigerants safely in accordance with an
industry recognised assessment specifi cation.
• Servicing shall only be performed as
recommended by the equipment manufacturer.
Maintenance and repair requiring the
assistance of other skilled personnel shall be
carried out under the supervision of the person
competent in the use of fl ammable refrigerants.
• Servicing shall be performed only as
recommended by the manufacturer.
2-2. Work
• Prior to beginning work on systems containing
fl ammable refrigerants, safety checks are
necessary to ensure that the risk of ignition is
minimised.
For repair to the refrigerating system, the
precautions in #2-2 to #2-8 must be followed
before conducting work on the system.
• Work shall be undertaken under a controlled
procedure so as to minimize the risk of a
fl ammable gas or vapour being present while
the work is being performed.
• All maintenance staff and others working in the
local area shall be instructed and supervised
on the nature of work being carried out.
• Avoid working in confi ned spaces.
• Wear appropriate protective equipment,
including respiratory protection, as conditions
warrant.
• Ensure that the conditions within the area
have been made safe by limit of use of any
fl ammable material. Keep all sources of ignition
and hot metal surfaces away.
2-3. 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
fl ammable atmospheres.
• Ensure that the leak detection equipment
being used is suitable for use with fl ammable
refrigerants, i.e. non sparking, adequately
sealed or intrinsically safe.
• In case of leakage/spillage happened,
immediately ventilate area and stay upwind and
away from spill/release.
• In case of leakage/spillage happened, do notify
persons down wind of the leaking/spill, isolate
immediate hazard area and keep unauthorized
personnel out.
