LIQUID LINE SOLENOID VALVE (PH1S090 only)
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). This solenoid valve requires Sporlan part
no. MKC-2 coils that must be purchased locally. Wire the sole-
noid valve in parallel with the compressor contactor coil.
The LLSV must be installed at the outdoor unit with the flow ar-
