Outdoor Unit Installation
NOTE
: The outdoor unit must be installed on a solid surface
(mounting base).
1. Place the rubber absorption cushions (supplied with the
outdoor unit) under the unit’s feet 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 mounting base.
3. Be sure that the unit is leveled.
MAKE REFRIGERANT PIPING CONNECTIONS (OUT-
DOOR UNIT) — To connect the refrigerant lines:
Make sure to properly identify and separate between the piping
and control cables coming from indoor unit No. 1 and the piping
and cables coming from indoor unit No. 2
Use only ”L” type sealed, dehydrated copper refrigerant tubing.
No other type of tubing may be used. Use of other types of tubing
will 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 formation of
sharp bends. Take care to avoid kinks or flattening of the tubing.
Keep the tubing free of dirt, sand, moisture, and other
contaminants to avoid damaging the refrigerant system.
Avoid sags in the suction line to prevent the formation of oil
traps.
Insulate each tube with 3/8
−
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.
