9,000, 12,000, 18,000, and 24,000 btuh
EMI offers the nest 13 SEER multi-zone Heat Pump
unit in the ductless split market. The Top Discharge
multi-zone Heat Pump Unit allows the installation of up
to four circuits from a single outside location when space
or aesthetic requirements limit the use of locations.
Each zone is independent and no mixing of refrigerant
will occur.
All EMI products are subject to ongoing develop-
ment programs and design and specications may
change without notice.
Compressors - Hermetically sealed high efciency
rotary, reciprocating, or scroll types, depending on zone
capacities. Motors are PSC type with inherent over-
load protection. Compressors are installed on resilient
Capacities/Efciencies - EMI’s Top Discharge
systems meet or exceed 13.0 SEER efciency require-
ments and 7.7 HSPF.
Cabinet - Fabricated of G90U galvaneal steel, n-
ished with corrosion inhibiting, polyester, powder coated
paint (2,000 hr. salt spray tested)
• Fan Guard - Black vinyl coated
P/N# 240006735 Rev. 2.0 [10/08]
• Cabinet Color - Light gray & black
• Concealed Service Valves
• Easy access service port connections at 45°
from valve body.
• Common suction pressure access point.
Refrigeration Circuit - The T2HB, T3HB and T4HB
are delivered with pre-charged refrigerant (R-22) for the
condenser coils and evaporators. Charging of the eld
installed piping is required. Unit refrigeration valves are
solid brass, for sweat connection. Solid core lter driers
are factory installed on all models.
Condenser Coil - The condenser coils are tested to
600 psig and are constructed of seamless copper tubing,
with enhanced aluminum ns. The tubes are mechani-
cally expanded for secure bonding to n shoulder.
Condenser Fan/Motor - The condenser fan is a large
diameter, high efciency, four blade aluminum propeller
type, directly connected to the totally enclosed, PSC
motor. The motor is tted with internal thermal protec-
tion. These multi-zone units are a drawthrough air ow
