York N1VSD10A06 User Manual

GENERAL
This instruction covers the installation of the following variable
speed blower sections.
The blower section is the basic component of an indoor modular
system which may be combined with various accessories listed
below to make an evaporator blower, evaporator blower with
electric heat, heat pump blower, and heat pump blower with
electric heat.
Because of the many ways this Air Handler may be applied and
the large variety of available accessories, the indoor portion of the
cooling or heat pump system comes to you in modules. These
modules must be field assembled to meet the specific needs of
the owner.
If this variable speed air handler is installed with a two stage
(H*DS) outdoor condensing unit, a thermal expansion valve kit
must be installed on the indoor side.
Check modules (accessories, etc.) received, against plans to be
sure all required modules are available for assembly.
INSPECTION
As soon as a unit is received, it should be inspected for possible
damage during transit. If damage is evident, the extent of the
damage should be noted on the carrier’s freight bill. A separate
request for inspection by the carrier’s agent should be made in
writing. See Form 50.15-NM for more information.
REFERENCE
This instruction should be used in conjunction with installation
instructions supplied with each accessory as well as the matching
outdoor section.
Installer should pay particular attention to the words: NOTE,
CAUTION and WARNING.
NOTES are intended to clarify or make the installation easier.
CAUTIONS are given to prevent equipment damage.
WARNINGS are given to alert the installer that personal injury
and/or equipment damage may result if installation procedures
are not handled properly.
