Instructions applicable to unit type with R410A refrigerant
• Don't use the refrigerant except for R410A. The R410A has the pressure 1.6 times higher than that of the
previous refrigerant.
The refrigerant R410A tank is marked with pink sign.
• Against charging different refrigerant, we change the diameter injection hole for operating valve of outdoor unit
and that of the check joint diameter of the R410A unit
To enhance the compression consistence, for refrigerant pipe, we also change machining dimension of
refrigerant flared pipe and opposite side dimension of flared nut.
When construction and maintenance, prepare the R410A special tools according to the below table.
• Don't use aeration tank, or it will cause changes of refrigerant composition and lack of refrigeration capacity.
• When filling the refrigerant, make sure to take it out of refrigerant tank in liquid form.
• Indoor unit refers to R410A appropriative unit. Please confirm the indoor unit available for connection according
to the catalogue. (If other indoor unit is connected, normal operation will be impossible.)
