Page 46: Vacuum Dry And Leakage Checking
RFWDB Low temperature floor ceiling-Technical Manual R32-50Hz 2 Vacuum Dry and Leakage Checking 2.1 Vacuum Dry: use vacuum pump to change the moisture (liquid) into steam (gas) in the pipe and discharge it out of the pipe to make the pipe dry. Under one atmospheric pressure, the boiling point of water(steam temperature) is 100℃. - Page 47 FWDB Low temperature floor ceiling-Technical Manual R32-50Hz Special vacuum dry procedure ②. This vacuum dry method is used in the following conditions: There’s moisture when flushing the refrigerant pipe. Rainwater may enter into the pipe. Vacuum dry for the first time ······ 2h pumping ③.

FWDB Low temperature floor ceiling-Technical Manual R32-50Hz 3 Additional Refrigerant Charge Caution ● Refrigerant cannot be charged until field wiring has been completed. ● Refrigerant may only be charged after performing the leak test and the vacuum pumping. ● When charging a system, care shall be taken that its maximum permissible charge is never exceeded, in view of the danger of liquid hammer. -
Page 49: Water Drainage
FWDB Low temperature floor ceiling-Technical Manual R32-50Hz 4 Water Drainage 4.1Gradient and Supporting 4.1.1 Keep the drainpipe sloping downwards at a gradient of at least 1/100. Keep the drainpipe as short as possible and eliminate the air bubble. 4.1.2 The horizontal drainpipe should be short. When the pipe is too long, a prop stand must be installed to keep the gradient of 1/100 and prevent bending. - Page 50 FWDB Low temperature floor ceiling-Technical Manual R32-50Hz 4.3 Upwards drainage (drain pump) For Four-way cassette (compact) For Round-way cassette 4.4 Convergent drainage 4.4.1.
