EMI S1H2D - Manual (Page 3)

Rome, New York, USA Enviromaster International LLC 3
part One “GeneraL”
The heat pump air conditioning systems shall be an EMI America Series split system. The system shall consist of
a high wall mounted packaged evaporator section Model WLH12 and matching America Series outdoor unit Model
S1H2. The units shall be made within North America. The units shall be listed by Intertek Testing Service (ITS) and
bear the ETL label. All wiring shall be in accordance with the National Electrical Code (N.E.C.). The units shall be rated
in accordance with ARI Standard 210/240 and bear the ARI label. The units shall be manufactured in a facility certified
to ISO 9001, which is an international standard used to provide guidance in the development and implementation of an
effective Quality Management System. The condensing unit shall contain R-22 refrigerant charge for the evaporator
section and condenser section. The system efficiency shall meet or exceed 2006 Federal Standards.
part twO “warrantY”
The units shall have a manufacturer’s warranty for a period of (1) year from date of installation. The compressor shall
have a warranty of (5) years from date of installation. If, during this period, any part should fail to function properly due
to defects in workmanship or material, it shall be replaced or repaired at the discretion of Enviromaster International
LLC. This warranty does not include labor. Manufacturer shall have twenty years experience in the U.S. market.
part three “perFOrManCe”
Each indoor unit shall provide at total minimum cooling capacity of 11,400 Btuh with a SEER of 13.0 and EER of 11.5
at ARI standard conditions. The system net minimum total cooling capacity shall be 11,400 Btuh and the net minimum
sensible cooling capacity shall be 8,760 Btuh with a circulating air rate of 400 CFM at 80°F (DB)/67°F (WB) entering
the indoor coil and 95°F (DB) air entering the outdoor coil. The total power consumption of the combined system shall
not exceed 992 Watts at these conditions. The indoor evaporator shall have an air throw of 15 feet. The system shall
provide a heating capacity of 10,600 Btuh with an HSPF of 8.0 and a COP of 3.4 at ARI standard conditions. The
heating capacity at 70°F indoor and 17°F outdoor shall be 6,200 Btuh.
part FOur “inDOOr unit”
The indoor unit shall be factory assembled, wired and contain a low Voltage transformer. The cabinet will be ABS
plastic with a light gray finish and have a galvanized steel sub chassis. The evaporator fan shall be an assembly with
line flow tangential fan direct driven by a single motor. The fan shall be statically and dynamically balanced and run on
permanently lubricated bearings. A motorized louver shall be provided with the ability to change the airflow vertically.
Horizontal-manually adjustable discharge louvers will be provided that can be placed in a fixed position. Return air
shall be filtered by means of a washable, reusable mesh filter. The evaporator coil shall be of nonferrous construction
with louvered fins bonded to rifled copper tubing. The tubing shall have inner grooves for high efficiency heat ex-
change. All tube joints shall be brazed with phoscopper or silver alloy. The coil shall be pressure tested at the factory.
A condensate management system with over flow protection, condensate drain pan with anti-corrosion coating and
drain shall be provided under the coil. System refrigerant flow shall be controlled by means of an orifice piston in the
indoor unit. The unit electrical power shall be 208/230 or 115 Volts, 1 phase, 60 Hertz. The system shall be capable of
satisfactory operation within theVoltage limits of 208/230 or 115 +/- 10%Volts.
part Five “COntrOL sYsteM”
The control system shall consist of a universal unit mounted, infrared compatible control package, configurable to
either unit mount or optional wall thermostat operation. Interconnected low voltage wiring shall run from indoor unit
to outdoor unit direct, no splices. When running low voltage wiring a double insulated, 18 gage cable is mandatory or
use shielded cable. The microprocessor shall be factory wired and located within the indoor unit. The control unit will
have a large LCD backlit display and be configurable to either unit mount or remote wall thermostat operation. Unit
mount-control operation allows the use of an optional IR hand held controller. The control shall have the capability
of sensing return air temperature and indoor coil temperature. The operational range will have adjustable set points
from 55°F to 90°F in one degree increments. The universal control can be used in cooling only, cooling with optional
electric heat, heat pump or heat pump with optional second stage electric heat. Operation modes include, cool, heat,
fan, auto change over and dry. Fan operation of auto (cycling), high and low (constant), auto fan operation automati-
cally selects fan speed according to heating or cooling demand. Dry mode operates cooling and optional electric heat
simultaneously to remove humidity (optional electric heat required). Test mode allows for ease of testing after instal-
lation (all timers are eliminated). Room air sampling (fan auto mode) cycles the fan on periodically to remove tem-
perature stratification. Fan purge runs the indoor fan for 60 seconds after call is dropped for cool/heat, improving unit
efficiency. Unit protection features include, anti short cycling compressor protection, minimum compressor run time,
freeze protection to prevent evaporator freeze, filter change indicator, condensate pan overflow switch, and integral
