Ultra Heating GMV5 Multi VRF for North America 5 Vacuum drying for the system 5.1 Selection requirement for the vaccum pump Do not use different vacuum pump for vaccum-pumping for different refrigerant system ； The final vacuum for the vacuum pump should reach -0.1MPa. The air discharge volume for the vacuum pump should reach 4L/S above;... - Page 90 Ultra Heating GMV5 Multi VRF for North America NOTICE (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 the dimension and length of field-installed liquid pipe.
- Page 91 Ultra Heating GMV5 Multi VRF for North America NOTICE! Liquid pipe that is within 20m (65-5/8 feet) doesn’t need to be added refrigerant. Therefore, the minimum quantity of additional refrigerant = (23-20)×0.054+11×0.022= 0.404kg(14oz). 5.3.2 Operation procedure for adding refrigerant (1) Put the charging tank on the weightometer, record the reading and then calculate the data after charging refrigerant;...
