1 Assembled XP13 outdoor unit
General
The XP13 outdoor unit uses HFC−410A refrigerant. This
unit must be installed with a matching indoor blower coil
and line set as outlined in the XP13 Engineering
Handbook. These outdoor units are designed for use in
check / expansion valve (CTXV) systems only and are not
to be used with other refrigerant flow control devices. An
indoor coil check / expansion valve approved for use with
HFC−410A must be ordered separately and installed prior
to operating the unit.
