Outdoor Unit Installation
NOTE: The outdoor unit must be installed on a solid surface
0nounting base).
1. Place the rubber absorption cushions (supplied with the
outdoor unit) under the unit's feets to prevent vibrations.
2. Fasten the outdoor unit legs to the mounting base, as shown
in Fig. 12. The cushion goes between the legs and the

MAKE REFRIGERANT PIPING CONNECTIONS (OUTDOOR
UNIT) To connect the refrigerant lines:
Use only "L" type sealed, dehydrated copper reliigerant tub-
ing. No other type of tubing may be used. Use of other types of
tubing will void the lnanufacturer's warranty.
Do not open service valves or remove protective caps from
tubing ends until all the connections are made.
Bend robing with special bending tools to avoid the forlna-
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 3/8-in. walled thermal pipe insu-
lation. Inserting the tubing into the insulation before making
the connections will save time and improve installation The suc-
tion and mixed-phase lines should never come in direct contact.
