38AQS008/40RMQ008 HEAT PUMP SYSTEM PIPING —
Addition of a liquid solenoid valve (LLSV) is recommended
when the piping system length exceeds 75 feet. The LLSV
must be a bi-flow type suited for use in heat pump systems.
The recommended valve is Sporlan model CB14S2 (5/8-in.
ODF, 7/8-in. ODM) available from the Replacement Com-
ponents Division as part number EF23JS-214. This solenoid
valve requires Sporlan part no. MKC-2 coils that must be
purchased locally. Wire the solenoid valve in parallel with
the compressor contactor coil.
The LLSV must be installed at the outdoor unit with the
flow arrow pointed toward the outdoor unit (in-flow
direction for the heating mode.)

40RMQ012 AND 38AQS016/40RMQ016 HEAT PUMP
SYSTEMS — The 38AQS012 and 016 units do not in-
clude filter driers. Filter driers must be field-supplied
and installed in 38AQS012/40RMQ012 and 38AQS016/
40RMQ016 systems. The filter driers used with these sys-
