Performance Specifications (cont.)
2.01 EQUIPMENT
A. General:
Factory-assembled, single-piece heating and/or
cooling unit. Contained within the unit enclosure
shall be compressor, coils, fans and fan motor, heat-
ing means, controls, all wiring and piping, and a full
refrigerant charge (R410A).
B. Chassis:
e chassis shall be a factory-assembled, single
piece heating and/or cooling unit, that is simple to
install and operate. Just slide the chassis into a wall
sleeve, plug it into an outlet, and operate aer instal-
lation. e chassis dimensions shall not exceed 42
in. wide and 16 in. high with room cabinet in place.
e chassis shall consist of the following functional
sections and components:
1. Operating Characteristics:
Chassis shall be capable of starting and running at
115 °F ambient outdoor temperature per maximum
load criteria of ARI Standard 310/380.
2. Electrical:
Chassis shall be equipped with a 58 in. power cord.
e chassis current draw shall be specied on the
chassis nameplate and match electrical require-
ments specied on the Contract drawing schedule
and specications.
e power cord plug conguration shall conform to
NEMA standards and the rating shall support the
current draw of the electric resistance heater.
For 265V installations, UL codes require the use of
an electrical equipped subbase for power cord usage
or hardwire conduit for non-corded installations.
C. Airow System:
e airow system shall consist of one permanent
split-capacitor, direct-drive permanently lubricated,
two-speed fan motor for the indoor and outdoor
fans. e outdoor fan shall be a dynamically bal-
anced, corrosion resistant polymer multi-blade
axial ow design, with integrated slinger ring. e
indoor fan shall be a dynamically balanced, poly-
mer, reverse curve blower wheel, to assure uniform
air distribution. e Fan Motor shall be of an
enclosed design to reduce the eects of moisture
and corrosion.
D. Compressor and Refrigerant:
e rotary-type Compressor shall be fully hermetic
with internal and external vibration isolation. e
refrigeration system will be sealed and contain a full
refrigerant charge (R410A).
E. Coils:
Condenser and evaporator coils to be constructed of
high-eciency, lanced sine wave enhanced alumi-
num ns and seamless axial grooved copper tubing,
necessary to achieve EER and COP rating, as speci-
ed on the chassis name plate.
F. Factory-Installed Electric Heater:
e factory-installed, open coil type, electric heater
is standard in heat/cool and heat pump chassis. e
electric heater shall contain both an automatic reset
and a one-shot over temperature protection device.
e heating capacity of the electric heater shall be as
identied on the Contract drawing schedule and in
the specications.
