[arnings on refrigerant leakage
Wdeqhfdq`ms cdmrhsx khlhs
Xhe room where the air conditioner is to be installed should be designed or chosen to meet the
standard in case of the refrigerant leakage3 which will ensure the refrigerant will not exceed the limit5
Xhe refrigerant V;87F in the air conditioner product is relatively safe without the poison and the
combustibility5 V;87F is environmentally friendly and is not restricted by the current or pending laws
regarding the protection of the ozone layer5
Visk of suffocation by the leakage of V;87F is minimal5 Mowever3 with the recent increase in the
number of high density buildings and use of multi air conditioner system to ensure effective use of
floor space3 energy conservation and individual control3 installers should ensure it is not possible
to exceed density limits in the event of a refrigerant leak5 Nn particular3 where a single unit of the
multi conditioner system is to be installed into a small room3 select a suitable model and installation
procedure so that if refrigerant leaks out3 density limits are adjacent rooms3 or install mechanical
ventilation combined with a gas leak detection device5
Xhe density can be calculated as shown belowA
Xotal amount of refrigerant /kg0
Qin5 volume of the room where indoor installed density limit /kg6m:0
Xhe density calculation must be in accordance with GW JR :>?5
[hen installing the unit3 please take the above into consideration according to the local laws3 regulation5
Rote 8A Nf there are 9 or more refrigerant
systems in a single area3 the refrigerant amount
should be considered as the individual outdoor5
Kor exampleA
Kor the possible leaking refrigerant in room F3
G and H is 87kg5
Kor the possible leaking refrigerant in room I3
J and K is 89kg5
Rote 9A Xhe standards for minimum room
volume are as followsA
/80 Ro partition /shaded portion0
/90 [hen there is an effective opening with
the adjacent room for ventilation of leaking
refrigerant gas /opening without a door3 or an
opening 758<- or larger than the respective
floor spaces at the top or bottom of the door05

85 Wafety caution concerned with new refrigerant
Xhe pressure of refrigerant V;87F is 85= times than that of refrigerant V995 Xhe refrigerant oil has
also been changed5 Xherefore be sure that the former refrigerant oil and other contaminants are
not mixed into the refrigerating cycle of the air conditioner with the new refrigerant during installation
or service work5 Nf incorrect work is performed3 there is a possibility of serious accident5 Yse tools
and materials exclusive to V;87F5
95 Hautions on installation6service
C Ion.t mix other refrigerants or other refrigerant oil with V;87F5
C Xhe types of tools and joins3 including the service port differ from those of the former refrigerant
in order to prevent mixtakes5
C Xhe operation pressure of V;87F is high3 always use pipes with the correct wall thickness and
which are specified for V;87F5
C Iuring installation3 ensure pipes are clean and ensure contaminants do not enter the pipes because
the system will be affected by the impuries such as the water3 the dirt3 oil3 and so on5
C Jnsure brazing is completed using the nitrogen5
C Yse a vacuum pump for air purge5
C V;87F refrigerant is an azeotropic mixture type refrigerant5 Xherefore use liquid state to charge
the refrigerant5 Nf gas state refrigerant is used3 the composition of refrigerant will change which affects
the performance characteristics of the air conditioner5
:5 Qaterials
C Kor the refrigerant pipes3 use copper pipes and keep the number of joints to a minimum5
C [hen using long copper pipe for V;87F3 it is recommended to use the seamless copper material
which includes bonded oil3 of amount ;7mg687ml or less5
C Io not use crushed3 deformed or discoloured pipes5
C Yse material in which the amount of contaminates inside the pipes or joint are kept to an absolute
minimum5
C Xhe use of flared joint for joining refrigeration pipes should not be used3 except where fitted to
the indoor6outdoor units by the factory5
