WARNING
PERSONAL INJURY AND UNIT DAMAGE
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.
CAUTION
!
UNIT DAMAGE HAZARD
Failure to follow this caution may result in equipment
damage or improper operation.
Do not leave system open to atmosphere any longer than
minimum required for installation. POE oil in compressor is
extremely susceptible to moisture absorption. Always keep
ends of tubing sealed during installation.
CAUTION
!
UNIT DAMAGE HAZARD
Failure to follow this caution may result in equipment
damage or improper operation.
If ANY refrigerant tubing is buried, provide a 6 in. (152.4
mm) vertical rise at service valve. Refrigerant tubing lengths
up to 36 in. (914.4 mm) may be buried without further
special consideration. Do not bury lines longer than 36 in.
(914.4 mm).
Outdoor units may be connected to indoor section using accessory
tubing package or field--supplied refrigerant grade tubing of correct
size and condition. For tubing requirements beyond 80 ft. (24.38
m), substantial capacity and performance losses can occur. Follow
the pipe sizing recommendations in the 280ANV Product data to
manage these losses.
Refer to Table 1 for field tubing diameters. Refer to Table 2 for
accessory requirements.

* Units are rated with 25 ft. (7.6 m) of lineset. See Product Data sheet for performance data when using different size and length line sets.
Notes:
1. Do not apply capillary tube indoor coils to these units.
2. For Tubing Set lengths between 80 and 200 ft. (24.38 and 60.96 m) horizontal and / or greater than 20 ft. (6.1 m) vertical differential, an accessory Liquid Line
Solenoid must be installed.
