SAFETY CONSIDERATIONS
Improper installation, adjustment, alteration, service, maintenance,
or use can cause fire, electrical shock, or other conditions which
may cause personal injury or property damage. Consult a qualified
installer, service agency, or your distributor or branch for infor-
mation or assistance. The qualified installer or agency must use
factory-authorized kits or accessories when modifying this prod-
uct. Refer to the individual instructions packaged with the kits or
accessories when installing.
Follow all safety codes and wear safety glasses. Have fire
extinguisher available. Read these instructions thoroughly and
follow all warnings or cautions attached to the unit. Consult local
and state building codes and Sheet Metal and Air Conditioning
National Association (SMACNA) for special installation require-
ments.
Recognize safety information. This is the safety-alert symbol
.
When you see this symbol on the unit or in instructions and
manuals, be alert to the potential for personal injury.
Understand the signal word DANGER, WARNING, or CAU-
TION. These words are used with the safety-alert symbol. DAN-
GER identifies the most serious hazards which will result in severe
personal injury or death. WARNING signifies hazards that could
result in personal injury or death. CAUTION is used to identify
unsafe practices which would result in minor personal injury or
product and property damage.
INSTALLATION CONSIDERATIONS
1. Install in non-condensing area with ambients between 32°F
and 120°F.
2. Use vibration isolators (flex connectors) on the zone dampers
and ductwork to minimize noise.
3. Place dampers away from areas that may be noise sensitive.
4. TXV is required in air conditioning and heat pump applica-
tions.
5. Use separate isolated transformer to supply power to Weath-
erMaker Two-Zone Center. (40va minimum, class 2, trans-
former, field supplied)
INTRODUCTION
The WeatherMaker Two-Zone System allows the air conditioning
and heating equipment to control temperatures in 2 distinct spaces
or zones within a building. Each zone has independent temperature
settings controlled by a thermostat.
NOTE:
Thermostats are purchased separately.
The comfort temperature settings can change automatically
through the use of schedules if programmable thermostats are
selected. This allows WeatherMaker Two-Zone to change the
temperature settings in zones to reflect occupancy or usage. The
WeatherMaker Two-Zone System uses motorized air volume
control dampers (also called zone dampers) to regulate the flow of
conditioned air into the zones.
INSTALLATION
Step 1—Check Equipment and Jobsite
INSPECT EQUIPMENT — File claim with shipping company,
prior to installation, if shipment is damaged or incomplete.
Step 2—Wiring
To prevent personal injury or possible equipment damage,
disconnect the power supply before routing wire.
All wiring must comply with local, state, and national codes.

Summary
NOTE: Use No. 18 AWG color-coded, insulated (35°C min) wire. If thermostats are to be located more than 100 ft from theWeatherMaker Two-Zone Center as measured along the controlvoltage wires, use 16 AWG colored-coded wires to avoid exces-sive voltage drop. All wiring is run back to the WeatherMakerT...
