B. REFRIGERANT LINE SETS
The refrigerant line set must be properly sized to assure
maximum efficiency and proper oil circulation.
Refer to Product Specifications and Long Line
Applications Guideline for line set sizing.
NOTE: Total line set length must not exceed 200 feet
(61m).
A crankcase heater must be used when the refrigerant
line length exceeds 80 feet (24.4m).
If outdoor unit is more than 10 feet (3m) higher than the
indoor coil, refer to the Extended Length Refrigeration
Piping Manual for instructions.
When the outdoor unit is higher than the indoor coil, the
vertical separation must not exceed 100 feet (31m).
When the outdoor unit is lower than the indoor coil, the
vertical separation must not exceed 50 feet (15.2m).
If it is necessary to add refrigerant line in the field, use
dehydrated
or
dry,
sealed,
refrigeration tubing. Do not use copper water pipe.
Do not remove rubber plugs or caps from copper tubing
until connections are ready to be made.
Be extra careful when bending refrigeration tubing.
Tubing can "kink" easily, and if this occurs, the entire
length of tubing must be replaced.
WARNING
!
PERSONAL
INJURY
HAZARD
Failure to follow this warning could result in
personal injury or death.
Relieve pressure and recover all refrigerant
before system repair or final unit disposal. Use all
service ports and open all flow−control devices,
including solenoid valves.
Federal regulations require that you do not vent
refrigerant to the atmosphere. Recover during
system repair or final unit disposal.

CAUTION
!
UNIT OPERATION HAZARD
Failure to follow this caution may result in
improper product operation.
Do not leave system open to atmosphere any lon-
ger than absolutely required for installation. Inter-
nal system components − especially refrigerant
oils − are extremely susceptible to moisture con-
tamination. Keep ends of tubing sealed during
installation until the last possible moment.
C. ROUTING AND SUSPENDING REFRIGERANT
LINES
Run refrigerant lines as straight and direct as possible,
avoiding unnecessary bends and turns. Always insulate
the entire suction line. Both lines should be insulated
when routed through an attic or when routed through an
underground raceway.
When routing refrigerant lines through a foundation or
wall, do not allow refrigerant lines to come in direct
contact with the building structure. Make openings large
enough so that lines can be wrapped with extra
insulation. Fill all gaps with RTV caulk. This will prevent
noise transmission between the tubing and the
foundation or wall.
Along floor or ceiling joists, suspend refrigerant lines so
that they do not contact the building structure, water
pipes, or ductwork. Use insulated or suspension type
hangers. Metal straps must be at least 1" (25mm) wide to
avoid cutting into the tube insulation. Keep the liquid and
suction lines separate. Refer to Figure 5.
