INSTALLATION INSTRUCTION
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.
