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.
