NOTES: 1. LIne A" is
only used for systems with hot gas bypass. See chart
above for line sizes for 15 and 25 ton circuits. Line "A" is size
d to
carry the oil at minimum load condition
s.
2. Line "B" incorporates inverted "p"-traps as sho
wn, with additional
"p"-traps each addit
ional 15 feet of rise, up to 50 ft. max. See chart
above for line size
s.
3. Line "C" is for horizontal hot gas lines and
carries the full flow.
See chart above for line size
s.
4. The liquid
li ne " D" s hould incorporate a check va lve fo r
applications where the condenser is at a lower temp
erature than the
receiver, to p
revent refrigerant migration during the off-cycle. See
chart above for line siz
es.
5. All pitches are 1/8" per foot downward in the di
rection of the
refrigerant f
low.
6. One refrigerant circu it is shown. There are
two separa te
refrigerant circuits for each AR2 modul
