As shown in Figure 3-17 and 3-18, the unit has refrigerated pipe connectors and labels on top and bottom.
Don’t burn the labels d
uring brazing. These labels assist and point out the connections to the discharge pipe
and liquid pipe of the indoor unit. The horizontal sections of the discharge pipes must be tilted downwards
from the compressor with a slope of at least 1:200 (5mm down for every 1m run). The discharge pipes must
be insulated from heat at the location where they are routed in the conditioned space (including the raised
floor).
