maintenance can cause personal injury, loss of life, or
damage to property.
Installation and service must be performed by a licensed
professional installer (or equivalent) or a service agency.
IMPORTANT
The Clean Air Act of 1990 bans the intentional venting of
refrigerant (CFCs, HCFCs and HFCs) as of July 1, 1992.
Approved methods of recovery, recycling or reclaiming
must be followed. Fines and/or incarceration may be
levied for noncompliance.
IMPORTANT
This unit must be matched with an indoor coil as speci­
fied in Lennox SSB*H4 Product Specification bulletin.
Coils previously charged with HCFC-22 must be
flushed.
NOTICE TO INSTALLER
UNIT PLACEMENT
It is critical for proper unit operation to place outdoor unit on an
elevated surface as described in Unit Placement section on page 7.
BRAZING LINE SET TO SERVICE VALVES
It is imperative to follow the brazing technique illustrated starting on
page 12 to avoid damaging the service valve's internal seals.

Shipping and Packing List

Check the unit for shipping damage and listed times below
are intact. If damaged, or if parts are missing, immediately
contact the last shipping carrier.
1 - Assembled outdoor unit.

General

Two-stage S-Classt SSB*H4 outdoor units use
HFC-410A refrigerant. This unit must be installed with a
matching indoor coil and line set as outlined in the Product
Specification bulletin. S-Classt SSB*H4 outdoor units
are designed for use in expansion valve systems (TXV)
only. They are not designed to be used with other
refrigerant flow control devices. The Product Specification
bulletin lists a TXV kit that must be ordered separately.
