INSTALLATION MANUAL---Important considerations
When compared with other refrigerants, R32 is more environmentally friendly. Please use this product
as instructed. This refrigerant is flammable and may combust under certain conditions, however when
this product is used as directed these risks are significantly reduced. Always consult with a trained
professional when maintaining or repairing an air conditioner.
Important Considerations
• The air conditioner you buy must be installed by professional personnel and
the “Ins
tallation manual” is used only for the professional installation personnel!
•
The installation specifications should be subject to our after-sale service regulations.
•
When filling the flammable refrigerant, please use caution to avoid serious injury.
•
A leak test must be done after the installation is completed.
•
It is a must to perform the safety inspection before maintaining or repairing an air c
onditioner
using flammable r
efrigerant in order to ensure that the fire risk is reduced to a minimum.
•
Requirements for the total weight of filled refrigerant and the area of a room to
be equipped
with an air c
onditioner (are shown as in the following Tables GG.1 and GG.2)
The maximum charge and the required minimum floor area
m1 = (4 m3) x LFL , m2 = (26 m3)) x LFL, m3 = (130 m3 )x LFL
Where LFL is the lower flammable limit in kg/ m3,R290 LFL is 0.038 kg/ m3,R32 LFL is 0.038 kg/ m3.
For the appliances with a charge amount m1 < M = m2:
The maximum charge in a room shall be in accordance with the following:mmax= 2.5 x (LFL)(5/4) x h0 x (A)1/2
The required minimum floor area Amin to install an appliance with refrigerant charge M (kg) shall be in accordance with
following: Amin = (M/ (2.5 x (LFL)(5/4) x h0)) 2
Where:
mmax is the allowable maximum charge in a room, in kg;
M is the refrigerant charge amount in appliance, in kg;
Amin is the required minimum room area, in m2;
A is the room area, in m2;
LFL is the lower flammable limit, in kg/m3;
h0 is the installation height of the appliance,in meters for calculating mmax or Amin, 1.8 m for wall mounted;
Warning
• Please read the manual before installing, using, or conducting maintenance.
•
Do not use means to accelerate the defrosting process or to clean, other than those recommended by
the manufacturer.
•
Be aware that refrigerants may not contain an odor.
