GENERAL
This instruction covers the installation of the following outdoor
units: E1FB012A(S)06, E1FB018A(S)06, E1FB024A(S)06,
E1FB030A(S)06, E9FB012S06, E9FB018S06, E9FB024S06,
and E9FB030S06.
The outdoor units are designed to be connected to a matching
indoor coil with either quick or sweat connect lines. Quick
connect units are factory charged with refrigerant for a match-
ing indoor coil and factory charged line sets are available in
various lengths. Sweat connect units are factory charged with
refrigerant for a matching indoor coil plus 15 feet of field
supplied lines.
Matching indoor coils are available with a thermal expansion
valve or an orifice liquid feed (YORKMATE flow control device)
sized for the most common usage. The orifice size and/or
refrigerant charge may need to be changed for some indoor-
outdoor unit combinations, elevation differences or total line
lengths. Refer to Application Data covering “General Piping
Recommendations and Refrigerant Line Length”.
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
Use this instruction in conjunction with the instructions for the
appropriate indoor unit, air moving system and accessories.
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 followed properly.
NOMENCLATURE
LIMITATIONS
The unit should be installed in accordance with all national and
local safety codes.
Limitations for the indoor unit, coil and appropriate accessories
must also be observed.
The outdoor unit must not be installed with any ductwork in the
air stream. The outdoor fan is the propeller type and is not
designed to operate against any additional external static pres-
sure.
The maximum and minimum conditions for operation must be
observed to assure a system that will give maximum perform-
ance with minimum service.
