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.
