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 words 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 which
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 150°F.

2. Use vibration isolators (flex connectors) on 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)

6. Load calculations must be performed to determine equipment

size. Equipment selection is matched to block load. It is
imperative equipment is not over sized.

7. Ductwork must be designed based off the sum of peak plus 25

percent oversize. It is imperative ductwork is not under sized.

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.
