Field Wire Routing

UNIT SIZES 030-050 — Field wiring can be brought into the unit through the basepan and roof curb or through the corner post in the side of the unit next to the control box.

A 31/2-in. NPT coupling for field power and a 3/4-in. NPT coupling for 24 v control wiring are provided in the basepan. There are two 45/8-in. knockouts in the corner post for field power wiring.

If field power wiring is brought through the roof curb, route wiring out through one of the 45/8-in. knockouts to the field- supplied disconnect and then back into the unit through the oth- er knockout. See Fig. 39 for recommended disconnect location.

If power wiring is brought through the side of the unit, route wiring from field-supplied disconnect through top 45/8-in. knockouts into unit.

If control wiring is to be brought in through the side of the unit, a 7/8-in. diameter hole must be drilled in the corner post next to the control box.

UNIT SIZES 055-105 — Field wiring is brought into the unit through the bottom of the control box. Wiring can be brought through the roof curb through field-supplied watertight connec- tions. See Fig. 40 and 41.

A 45/32-in. hole for field power wiring and a 7/8-in. hole for

24 v control wiring are provided in the bottom of the control box. Field-supplied couplings must be used when routing wir- ing into the control box.

See Fig. 40 and 41 for recommended disconnect location.

Field Electrical Connections

IMPORTANT: The 48ZN,ZW,Z8 units generate, use, and can radiate radio frequency energy. If units are not installed and used in accordance with these instructions, they may cause radio interference. They have been tested and found to comply with limits of a Class A computing device as defined by FCC (Federal Commu- nications Commission) regulations, Subpart J of Part 15, which are designed to provide reasonable protection against such interference when operated in a commercial environment.

POWER WIRING — Units are factory wired for the voltage shown on the unit nameplate. The main terminal block is suit- able for use with aluminum or copper wires. Maximum wire size varies according to disconnect size.

Units Without Factory-Installed Disconnect — When install- ing units, provide a disconnect per NEC (National Electrical Code) of adequate size (MOCP [Maximum Overcurrent Pro- tection] of unit is on the informative plate). All field wiring must comply with NEC and all local codes. Size wire based on MCA (Minimum Circuit Amps) on the unit informative plate. See Fig. 42 for power wiring connections to the unit power ter- minal block and equipment ground. Maximum wire size is two

(2) 500 MCM (thousand circular mils) conductors per pole.

It features a high Seasonal Energy Efficiency Ratio (SEER) and Heating Seasonal Performance Factor (HSPF), allowing for reduced energy consumption and lower utility bills. This model is equipped with advanced inverter technology that enables variable speed operation, significantly reducing noise levels and providing consistent temperature control.

Turning to the Z6 model, it is engineered for both robustness and reliability. It incorporates a modular design that allows for easy installation and maintenance. One of its key features is the use of innovative insulation materials that minimize sound levels, making it ideal for noise-sensitive environments. Furthermore, the Z6 series comes with a smart control system that allows users to monitor and adjust settings remotely, further optimizing energy usage.

The 48ZG and 48ZT models are designed with durability in mind. They utilize a fully enclosed compressor system that protects critical components from environmental damage. These models also boast enhanced dehumidification capabilities, making them suitable for humid climates. Equipped with advanced filtration systems, they improve indoor air quality by removing allergens and particulates effectively.

Carrier's ZW series exemplifies cutting-edge technology with its dual fuel capability, which allows the system to switch between a heat pump and a gas furnace, depending on outdoor temperatures. This feature maximizes energy savings while ensuring a comfortable indoor climate year-round. The ZW models also support integration with smart home systems, providing seamless control through mobile apps.

Collectively, these Carrier models are designed to meet the diverse needs of today’s consumers, offering a blend of efficiency, comfort, and intelligent control. Their ability to adapt to various environmental conditions while maintaining optimal performance makes them a leading choice in the HVAC market. With a focus on sustainability, these systems not only offer significant energy savings but also contribute to reducing the carbon footprint. As technology continues to evolve, Carrier remains at the forefront, delivering reliable, innovative HVAC solutions.
