Carrier 59SC2A - Electrostatic Discharge (Esd) Precautions

59SC2A
13. These furnaces SHALL NOT be installed directly on carpet-
ing, combustible tile, or any other combustible material oth-
er than wood flooring. In downflow installations, factory
accessory floor base MUST be used when installed on com-
bustible materials and wood flooring. Special base is not re-
quired when this furnace is installed on manufacturer’s Coil
Assembly Part No. CNRV, CNPV, CAP, or CAR or when
Coil Box Part No. KCAKC is used. See Table 2 for clear-
ance to combustible construction information.
INTRODUCTION
This 4-way multipoise Category IV condensing furnace is CSA
design-certified as a direct-vent (2-pipe) or non-direct vent
(1-pipe) furnace. See Fig. 2. The furnace is factory-shipped for
use with natural gas. The furnace can be converted in the field for
use with propane gas when a factory-supplied conversion Kit is
used. Refer to the furnace rating plate for conversion kit
information.
These furnaces are not approved for installation in recreational
vehicles or outdoors. Single-stage furnaces (40,000 through
120,000) are approved for installation in manutactured
housing/mobile homes with manufacturer-approved accessory.
The conversion kit is required for use with both natural and
propane gas. The furnace must also be installed on a
factory-supplied accessory combustible floor base or evaporator
coil casing.
This furnace is designed for minimum continuous returm-air
temperature of 60°F (15°C) db or intermittent operation down to
55°F (13°C) db such as when used with a night setback
thermostat. Return-air temperature must not exceed 80°F (27°C)
db. Failure to follow these return-air temperature limits may affect
reliability of heat exchangers, motors, and controls. See Fig. 3.
The furnace should be sized to provide 100 percent of the design
heating load requirement plus any margin that occurs because of
furnace model size capacity increments. Heating load estimates can
be made using approved methods available from Air Conditioning
Contractors of America (Manual J); American Society of Heating,
Refrigerating, and Air-Conditioning Engineers; or other approved
engineering methods. Excessive oversizing of the furnace could
cause the furnace and/or vent to fail prematurely.
For accessory installation details, refer to the applicable instruction
literature.
NOTE: Remove ail shipping materials, loose parts bag, and
literature before operating the furnace. See Table 1.
CODES AND STANDARDS
Follow all national and local codes and standards in addition
to these instructions. The installation must comply with
regulations of the serving gas supplier, local building, heating,
plumbing, and other codes. In absence of local codes, the
installation must comply with the national codes listed below and
all authorities having jurisdiction.

ELECTROSTATIC DISCHARGE (ESD)
PRECAUTIONS PROCEDURE
4& CAUTION
FURNACE RELIABILITY HAZARD
Failure to follow this caution may result in unit component
damage.
Electrostatic discharge can affect electronic components.
Take precautions during furnace installation and servicing
to protect the furnace electronic control. Precautions will
prevent electrostatic discharges from personnel and hand
tools which are held during the procedure. These
precautions will help to avoid exposing the control to
electrostatic discharge by putting the furnace, the control,
and the person at the same electrostatic potential.
