GMV-36WL-B-T(U) Multi Pro Ultra Heat Systems High Walls

Product Information

The product is an outdoor unit with different nominal capacities and SEER (Seasonal Energy Efficiency Ratio) ratings. It comes in Multi-Pro Single Fan Models and Multi-Pro Dual Fan Models. The Multi-Pro Ultra Heat Systems have a lower SEER rating but provide ultra heat capabilities. The product has different outdoor model numbers, pipe connections, and MCA (Minimum Circuit Amps) values based on the capacity and model type. It also has common indoor units, including high walls, ceiling cassettes, compact consoles/floor ceiling models, and different combinations of outdoor models.

Product Usage Instructions

Choose the appropriate outdoor unit model based on your cooling and heating needs.
Check the nominal capacities and SEER ratings to ensure they meet your requirements.
Check the MCA and MOCP (Maximum Overcurrent Protection) values to ensure the electrical circuit can handle the unit’s power requirements.
Check the recommended breaker size to ensure it is compatible with the electrical circuit.
Check the factory charge of the outdoor unit to ensure it h as a sufficient refrigerant.
Choose the appropriate indoor unit based on your preferences and space requirements.
Follow the piping rules for single-zone piping or multi-zone piping based on your installation requirements.
Connect the indoor and outdoor units using the appropriate pipe connections.
Follow the installation guidelines provided in the user manual for proper installation and operation of the product.

Piping Rules

Piping limitations are important and absolute. EXNO CEPTIONS.
98 4 fequivalent ofeet piping
All piping lengths within the Piping Rules are in one direction, measuring the liquid line.

Control options

Wired Controller (Included with all Horizontal Ducted Units and AHU Kits) Optional for All Others
XK46
Wireless remote control (Included with Ductless Units)

XE70-33/H
Included with Multiposition Air Handler. Optional for Others. Controller with 7-day programmable function, Max. Indoor unit connectable is 16

CE52-24/F Central Controller
Enables centralized local control. Can control and monitor up to 16 MultiPRO Systems with up to 32 indoor units. Expanded option also available. Enables 7-Day programming, grouping, and function lockout.
ME30/24D1(BM) BACnet and Modbus Gateway
Converts GREE CAN bus to BACnet or Modbus building management protocols for monitoring and control of up to 16 MultiPRO systems and 160 indoor units.

Refrigerant Piping Installation Guidelines & Descriptions

Refrigerant Piping

Heat Pump has two pipes, liquid and gas
Mode changes occur in outdoor unit

Y-Branches

For even distribution of refrigerant to and from indoor units
Specially engineered for even flow
Different sizes dependent on capacity downstream

Headers

Must be installed level
Cannot have Y-Branch downstream
Includes caps for unused ports

Y-Branches Installation

Cannot be sideways, will cause poor performance
Must be level or plumb within 15 degrees

Y-Branch Installation

Must have 20” between Y-Branches, elbows, and between Y-Branches and elbows
Failure to meet these minimums can cause turbulence and refrigerant noise

Y-Branch Equivalent Length

Equals 20” (0.5m)
Used when calculating total piping and additional refrigerant charge

Basic Piping Rules Defined

Note: The following is a basic set of rules for piping lengths. The MultiPRO systems are capable of far greater lengths and more complex configurations. Use our MultiPRO System Builder, MultiPRO Selector, or see installation manual for more details

SINGLE ZONE

Single Zone Piping Limits	2 and 2.5T	3, 4, and 5T
Maximum Length ODU to IDU:	328′	393′
Max Height ODU Above IDU:	98′	164′
Max Height ODU Below IDU:	98′	131′

Single Zone MultiPRO
The piping sizes are determined by ODU
Model	Liquid	Gas
2 Ton Outdoor Unit	3/8″	5/8″
2.5 Ton Outdoor Unit	3/8″	5/8″
3 Ton Outdoor Unit	3/8″	5/8″
4 Ton Outdoor Unit	3/8″	5/8″
5 Ton Outdoor Unit	3/8″	3/4″
If necessary, reduce the piping size at the indoor unit

DUAL AND MULTIZONE

Dual/Multi Zone Piping Limits	2 and 2.5T	3, 4, and 5T
Max Length IDU to Y-Branch or Header:	98′	98′
Max Height IDU to Y-Branch or Header:	30′	30′
Max Height ODU Above IDU:	98′	98′
Max Height ODU Below IDU:	98′	98′
Note: these are basic limitations. Actual limitations are far greater. Use MultiPRO System Builder, MultiPRO Selector, or see installation manuals for more details.

Dual and Multi Zone MultiPRO
Model Liquid Gas			Model Liquid Gas
