FOR FUTURE REFERENCE
The S-Class '" SPA outdoor units use R-410A HFC refrig-
erant. This unit must be installed with a matching indoor
coil and line set as outlined in the Lennox Engineering
Handbook. SPA outdoor units are designed for use in ex-
pansion valve (TXV) systems only. They are not designed
to be used with other refrigerant flow control devices. The
Lennox Engineering Handbook lists indoor TXV kits that
must be ordered separately.
These instructions are intended as a general guide and do
not supersede local codes in any way. Consult authorities
who have jurisdiction before installation.
