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.

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′ |
