MAKE REFRIGERANT PIPING CONNECTIONS (OUTDOOR
UNIT) To connect the refrigerant lines:
Make sure to properly identit) and separate between the pip-
ing and control cables coming tiom indoor unit No. 1 and the pip-
ing and cables coming from indoor unit No. 2
Use only "L" type sealed, dehydrated copper refrigerant tub-
ing. No other type of tubing may be used. Use of other types of
tubing wilt void the manufacturer's warranty.
Do not open service valves or remove protective caps from
tubing ends until all the connections are made.
Bend tubing with special bending tools to avoid the forma-
tion of sharp bends. Take care to avoid kinks or flattening of the
tubing.
Keep the tubing tree of dirt, sand, moisture, and other con-
taminants to avoid damaging the refrigerant system.
Avoid sags in the suction line to prevent the formation ofoil
traps.
Insulate each tube with 318-in. walled thermal pipe
insulation. Inserting the tubing into the insulation before making
the connections will save time and improve installation The
suction and mixed-phase lines should never come in direct
contact.
