Label the refrigerant piping (injection and suc- tion pipes) as well as the associated electrical control lines of each interior unit with a letter. Only connect the lines to their associated con- nections. NOTICE! Always pay attention to the affiliation of the electrical lines and refrigerant piping! The con- nections of the individual circuits must not be mixed up.
REMKO Series RVT-ARCTIC 6.4 Leak testing Once all the connections have been made, the pressure gauge station is attached to the Schrader valve as follows (if fitted): red = small valve = high pressure blue = large valve = suction pressure Once the connection has been made successfully, the leak test is carried out with dry nitrogen.
Condensate drainage 6.5 Adding refrigerant connection and safe The units contain a basic quantity of refrigerant. In addition, an additional amount of refrigerant must drainage be added for refrigerant piping lengths exceeding 5 metres per circuit. Refer to the following chart: Up to and From 5m to incl.
