PRODUCT OVERVIEW SUPERIOR DESIGNS PROVIDE EASY SOLUTIONS TO COMPLEX PROBLEMS GREE Ductless Multi Zone systems provide quiet comfort and energy efficient heating and cooling in up to five different rooms – without ductwork. For most residential and light commercial applications, this is the ideal solution to balance comfort, efficiency and ease of installation. This Inverter-driven system offers Seasonal Energy Efficiency Ratings (SEER) up to 16.
PRODUCT OVERVIEW Self-Diagnostics System Each indoor and outdoor unit continuously runs a series of multi-point diagnostic tests on the system, to automatically scan for unacceptable operating conditions or malfunctions. If such conditions occur, the system takes corrective action or stops. The fault code will be shown on the indoor, outdoor and wired controller displays. Problems and system status are displayed with comprehensive diagnostic codes to simplify system troubleshooting and shorten repair times.
+Multi Outdoor Units Each +Multi heat pump is powered by Gree’s energy efficient G-10 Inverter and a variable speed compressor. These units can heat and cool up to five zones without distribution boxes, and all offer the G-10 advantages of energy savings, noise reduction and room temperature consistency. Each outdoor coil also features a corrosion-resistant Gold Fin coating to withstand corrosive environments and to further promote energy efficiency.
FEATURES AND BENEFITS Low Voltage Start Up Having stable electrical power is not always an option. The Gree Multi Zone units will operate from 170v to 265v which is suitable for unstable power supply areas. Self-Diagnosis With an on-board computer using real-time diagnostics, the Gree Multi Zone system helps to prolong its own life. The automatic diagnosis feature continuously scans for unacceptable operating conditions or malfunctions. If such conditions occur, the system takes corrective action or stops.

MINIMUM OUTDOOR CLEARANCE SPECIFICATIONS The unit installation must meet or exceed the following minimum clearances for proper operation.
+Multi Outdoor Units ELECTRICAL WIRING The main power is supplied to the outdoor unit. System must be on a single dedicated circuit. Use appropriate wire size and circuit breaker (or fuse) size for proper system overcurrent protection. Follow all local building codes and NEC (National Electrical Code) regulations. Interconnecting Cable Wiring Diagram The indoor units are powered by the outdoor unit.
ELECTRICAL WIRING Local codes may require a disconnect switch within sight of the indoor unit. For these installations, use a DFS Disconnect Switch Accessory Kit (Part No: DFS-SWITCH-A) to break wires going to the N(1), 2, 3, terminals on the indoor unit, as shown in the wiring diagram below: Interconnecting Cable with Disconnect Switch Wiring Diagram CONDENSATE REMOVAL Install condensate drain to bottom of outdoor unit to safely and effectively route condensate water to a safe location.
+Multi Outdoor Units INDOOR UNIT COMBINATIONS SELECTION CRITERIA When selecting a variable speed system, match the system capacity to the calculated load of the building. Since a variable speed system can accommodate a wide range of loads, it is important to understand the percentage of time that the system will be required to run at both maximum and minimum load points. Generally there will be more load diversification in residential applications (shifting from low load to high load).
