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 informa- tion 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, and 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. NOTE is used to highlight suggestions which will result in enhanced installation, reliability, or operation.

INSTALLATION CONSIDERATIONS

Before the actual installation of a zoning system can begin, decisions need to be made to determine the number and location of zones. This affects duct and damper selections.

This instruction covers the physical installation and start up of the Carrier 3-Zone system. Use this instruction to guide the actual installation process after all the air side decisions have been made.

1.Install in non-condensing areas with ambients between 32°F and 158°F.

2.A TXV is required on the indoor coil when used with all residential split system equipment.

3.A separate transformer is not needed to power the 3-Zone system. Up to five dampers may be used in each zone by electrically connecting them in parallel.

4.Load calculations must be performed for each zone’s peak demand. Size each zone duct for at least its peak demand plus 25%. Size equipment for the building block load, not the sum of zone peak demands. It is important that the equipment not be oversized.

5.When only two zone operation is needed, any two of the three zone connections may be used. There is no inherent priority dependent on zone number.

UNIT DAMAGE HAZARD

Failure to follow this caution may result in unit damage. TXV on indoor coil is required with all residential split system equipment.

INTRODUCTION

The Carrier 3-Zone system allows the air conditioning and heating equipment to control temperatures in 3 distinct spaces or zones within a building. Each zone has independent temperature settings controlled by a conventional thermostat.

There are two distinct controllers:

•ZONECC3ZAC01 - Single Stage Heat / Single Stage Cool using conventional single stage thermostats.

•ZONECC3ZHP01 - Three Stage Heat / Two Stage Cool compatible for HP and multi-stage application thermostats and equipment.

Each system controller is comprised of a three-zone controller and a duct temperature sensor.

NOTE: Thermostats are purchased separately.

The comfort temperature settings can change automatically through the use of schedules if programmable thermostats are selected. This allows the Carrier 3-Zone to change the temperature settings in zones to reflect occupancy or usage. The Carrier 3-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 Job Site

INSPECT EQUIPMENT — File claim with shipping company, prior to installation, if shipment is damaged or incomplete.

Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.
