WARNING
!
PERSONAL INJURY AND ENVIRONMENTAL
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 refrigerant is not vented into the
atmosphere. Recover during system repair or final unit disposal.

*.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.
†.Required maximum diameter for applications using greater than 25 ft. (7.6 m) of lineset is 7/8 in.
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.
Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.

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. PVE oil in compressor is extremely
susceptible to moisture absorption. Always keep ends of tubing sealed
during installation.
!
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. Federal regulations require that refrigerant is not vented
into the atmosphere. Recover during system repair or final unit disposal.
For tubing requirements beyond 80 ft. (24 m), substantial capacity and
performance losses can occur. Follow the pipe sizing recommendations
in the 26VNA1 Product data to manage these losses.
Refer to Table 1 for field tubing diameters. Refer to the Product Data for
accessory requirements.
Refrigerant pipe should be installed with the minimum length possible
and practical for the application. Piping should be protected from
physical damage in operation and in service and be in compliance with
national and local codes such as ASRHAE 15, ASHRAE 15.2, IAPMO
Uniform Mechanical Code, ICC International Mechanical Code, or CSA
B52. When piping is installed through studs in a wall, steel plates should
be used for protection with a minimum thickness of 16 gauge.
All field joints shall be accessible for inspection prior to being covered
or enclosed.
