Compressors - Hermetically sealed high efciency
rotary compressors. Motors are PSC type with inherent
overload protection.
Condenser Fan/Motor - The condenser fan is a large
diameter, high efciency propeller type, which is directly
connected to the totally enclosed PSC motor. The S2H
units are draw-through airow design and the PSC motor
is tted with internal overload protection.
Condenser Coil - Condenser coils are seamless cop-
per tubing arranged in staggered conguration with
enhanced aluminum ns tested to 460psig. The tubes
are mechanically expanded for secure bonding to the
n shoulder.
Refrigeration Circuits - The S2H is delivered with
pre-charged refrigerant for the condenser coils and
evaporators while charging of eld installed piping is
required. Unit refrigeration service valves are solid brass
for sweat connection. Solid core lter driers are factory
installed on all models.
Refrigerant Run Options - The standard system will
support refrigerant runs to the inside unit of 35’ of lift,
up to 100’ of interconnect.
Reverse Cycle Operation S2H - A four-way reversing
valve, solenoid activated by 24v, is energized for cool-
ing operation. A TXV with internal check valve provides
proven operation through all temperature ranges when
in the heat pump mode.

Nominal Capacities:
9,000 and 12,000 Btuh
EMI offers the nest high capacity dual zone outdoor
units in the ductless split market, the S2H High Capacity
Condensing Unit. The S2H allows the installation of two
circuits from a single outside location when space or aes-
thetic requirements limit the use of locations. The S2H has
easy access interconnect valves on the back of the unit
and each zone is independent so no mixing of refrigerant
will occur. All 9,000 and 12,000 Btuh units are equipped
with the Duratec Performance package which includes a
large capacity suction accumulator with surge bafes and
enhanced oil management and a factory installed solid
core lter drier.
All EMI products are subject to ongoing develop-
ment programs so design and specications may
change without notice.
