Carrier WeatherMaker 8000 - ELECTROSTATIC DISCHARGE (ESD) PRECAUTIONS PROCEDURE

2
home heating requirements. This furnace
family provides the widest range of
heating capacities available.
The superior attention to cabinet
detail is obvious. The Carrier
WeatherMaker 8000 Two-Speed
features 1-piece, seamless, wrap-
around construction. There are no spot
welds on the exterior surfaces of the
WeatherMaker 8000 Two-Speed
Furnace. There is also double protection
for the cabinet. First, a galvanized steel
substrate provides resistance to rusting.
Then the cabinet is constructed of
prepainted steel—the same high-quality
finish found on refrigerators and
dishwashers.
Perhaps the most advanced feature
of the WeatherMaker 8000 Two-Speed
is the state-of-the-art microprocessor
control center which shows true
leadership in furnace technology.
The simplified electronics in this
control provide high reliability while
performing many of the functions of
older, electro-mechanical devices in
other furnaces. Advanced features of
the control show Carrier’s true
leadership in furnace technology.
The control provides blower delay at
start-up and shutdown, while
monitoring furnace operations and
functions. In the unlikely event of a
service call, in less than a minute, the
technician can use the self-test feature
to determine if a major component has
failed. The control will check itself,
then the low and high inducers, silicon
carbide ignition, and low-, medium-,
and high-speed blower. The control
also features a 3-amp fuse that protects
the transformer and control.
Our induced-combustion furnace has
a patented draft safeguard switch. The
draft safeguard switch will stop furnace
operation if the vent system becomes
blocked or is not operating properly.
Best of all, the Carrier
WeatherMaker 8000 two-speed is
easily installed. Many features make
this furnace the easy choice for
replacement or new construction
markets. Left and right connections
are provided for gas and electrical
supplies. An easy-to-remove bottom,
heating and cooling blower speed
selector, cased or uncased cooling
coils, low-voltage humidifier, and
electronic air cleaner terminal
connections are among other features.
