Notes:
① Cooling only unit (GMVL type) has no items on heating;
②Noise was tested in semi-silenced room, so the actual noise value will be a little higher for change of
ambient;
③Nominal capacities are based on the following conditions:
Cooling Heating
Indoor :27℃(80.6℉)/19℃(66.2℉)
Outdoor: 35℃(95℉)/-
Indoor: 20℃(68℉)/-
Outdoor : 7℃(44.6℉)/6℃(42.8℉)

Note:
①The comprehensive energy-efficiency ratio is (the cooling capacity obtained by indoor unit + Heating capacity
of hot water / Power consumption. Example: ECOP= (8.0kW+（8.0kW+2.86kw）)/2.86 kW=6.6
② The performance data of the air conditioner unit are measured under rated working conditions.
③ The R410A charge volume above refers to the charge volume in the outdoor unit at the time of shipment.
During installation, the charge volume of additional refrigerant shall be calculated according to the pipe length
and the configuration of indoor units.
④ The data above shall be based on the nameplate.
