GENERAL
This instruction covers the installation of the following outdoor
units: E1FD018A(S)06, E9FD018S06, E1FD024A(S)06,
E 9 F D0 24 S 06 , E 1F D0 30 A (S )06 , E 9F D 03 0S 06 ,
E 1F D 03 6A (S )06 , E9 FD0 36S 06, E 1FD 036 S(25 ,4 6),
E1FD042A(S)06, E1FD048A(S)06 E1FD048S(25, 46),
E1FD060A(S)06, E1FD060S06(25, 46).
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” (Form
690.01-AD1V).
THIS UNIT IS NOT EQUIPPED WITH A FILTER DRIER. A
SOLID CORE BI-FLOW DIRECTIONAL FILTER IS RE-
QUIRED FOR INSTALLATION AND ANY TIME THE REFRIG-
ERANT CIRCUIT IS OPENED.
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 delivery receipt. A
separate request for inspection by the carrier’s agent should
be made in writing. See Local Distributor for more information.
