Safety Precautions

f) Precautions shall be taken to avoid

excessive vibration or pulsation to
refrigerating piping.

g) Ensure protection devices, refrigerating

piping and

ttings are well protected

against adverse environmental effects
(such as the danger of water collecting and
freezing in relief pipes or the accumulation
of dirt and debris).

h) Expansion and contraction of long runs

piping in refrigerating systems shall be
designed and installed securely (mounted
and guarded) to minimize the likelihood
hydraulic shock damaging the system.

i) Protect the refrigerating system from

accidental rupture due to moving furniture
or reconstruction activities.

j) To ensure no leaking,

eld-made refrigerant

joints indoors shall be tightness tested.
The test method shall have a sensitivity of
5 grams per year of refrigerant or better
under a pressure of at least 0.25 times the
maximum allowable pressure (>1.04 MPa,
max 4.15 MPa). No leak shall be detected.

1. Installation (Space)

• Product with

ammable refrigerants, shall

be installed according to the minimum room
area, Amin (m²) mentioned in Table A of the
Installation Instructions.

• In case of

eld charge, the effect on

refrigerant charge caused by the different pipe
length has to be quanti

ed, measured and

labelled.

• 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 of

ces for

proper handling.

2. Servicing
2-1. Service personnel

• The system is inspected, regularly supervised

and maintained by a trained and certi

service personnel who is employed by the
person user or party responsible.

• Ensure the actual refrigerant charge is in

accordance with the room size within which
the refrigerant containing parts are installed.

• Ensure refrigerant charge not to leak.
• Any quali

ed person who is involved with

working on or breaking into a refrigerant
circuit should hold a current valid certi

cate

from an industry-accredited assessment
authority, which authorizes their competence
to handle refrigerants safely in accordance
with an industry recognised assessment
speci

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

ammable refrigerants.

• Servicing shall be performed only as

recommended by the manufacturer.

2-2. Work

• Prior to beginning work on systems containing

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

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 con

ned spaces. Always

ensure away from source, at least 2 meter of
safety distance, or zoning of free space area
of at least 2 meter in radius.

• Wear appropriate protective equipment,

including respiratory protection, as conditions
warrant.

• Keep all sources of ignition and hot metal
