7.3.2 Refrigerant Adding
(1) Refrigerant quantity of outdoor unit before delivery:
Mode
GMV-HY36WLT/A-T(U)
GMV-HY48WLT/A-T(U)
Refrigerant Qty (kg/oz)
6.0(212)
6.0(212)
1) The refrigerant amount charged before delivery doesn’t include the amount that needs to be added to indoor units and the
connection pipeline.
2) Length of connection pipe is decided on site. Therefore the amount of additional refrigerant shall be decided on site according to
3) Record the amount of additional refrigerant for convenience of after-sales service.
(2) Calculation of the amount of additional refrigerant
Calculation method of the quantity of additional refrigerant (based on liquid pipe)
Quantity of additional refrigerant = ∑length of liquid pipe X q
