1 Certified in accordance with the AHRI Unitary Small Air-Source Heat Pumps (USHP) Certification Program which is based on the latest edition of AHRI Standard 210/240.
2 Other pipe restrictions and requirements exist. Please consult installation manuals or technical data book for full details.
3 Vertical separation: 131' when outdoor unit is lower than the indoor units, 164' when the outdoor unit is higher than the indoor units.
4 When cooling in outside temperatures between 0°F ~ 23°F, wind baffles are required. When outside temperature is between 0°F ~ 23°F, 50% operating capacity should be maintained to ensure reliability while in cooling mode.
Accessories
- Wind Baffles: Front (WBF-1M2), Back (WBB-2M)
- Wi-Fi Adapter (MIM-H03UN)
- Base Pan Heater Kit (MHC-015EE)
- External contact control interface module (operation and error output, night silent mode manual activation) (MIM-B14)
Safety Certifications & Protection Devices
Certifications: ETL (UL 1995)
Protection Devices: Intelligent logic to ensure proper operation within unit design limitations and operational parameters. Includes high pressure sensor, low pressure sensor, over-voltage protection, compressor over-current protection, current transformer, fan motor voltage protection, fan motor thermal protection, and high voltage fuses.
Compatibility
Only compatible with Samsung DVM S indoor units (AM****N***H***) that are equal to or less than 60,000 Btu/h and the MCM-D211UN Universal Communication Kit.
Construction
The unit shall be galvanized steel with a baked on powder coated finish.
Heat Exchanger
The heat exchanger shall be mechanically bonded fin to copper tube. The aluminum fins of the heat exchanger shall have a protective coating. Salt spray test method: ASTM-B117-18 - the heat exchanger showed no unusual rust or corrosion development to 2,280 hours.
Controls
The unit shall be operated via NASA Protocol with controls provided by Samsung. The outdoor unit shall have a removable EEPROM that stores unit serial number, startup information, system settings, system tag/name, and other information. Controls shall integrate with Samsung central controllers without additional interface modules. Control wiring shall be 16 AWG X 2 shielded wire.
Refrigerant System
The compressor shall be Samsung hermetically sealed, inverter driven, twin BLDC Rotary type. The condenser shall be able to provide simultaneous heating and cooling operation. Refrigerant flow shall be controlled by EEV (electronic expansion valve) throughout the system. A flat plate subcooler device will improve capacity at extreme system refrigerant pipe lengths and reduce refrigerant noise. Installation of an HR Changer (MCU-R4NEK0N) is mandatory. If additional Mode Control Unit(s) are needed, the HR Changer must be installed between the outdoor unit and addtional MCU's. Please refer to the installation manual for compatible MCU models. Indoor units that will be used for cooling only year-round may be piped direct to the liquid and suction pipes after the HR Changer and bypassing MCU connection.
Other Features
- Advanced oil recovery cycle logic to ensure adequate oil level is maintained in the compressor. Oil recovery operation shall not interrupt heating or cooling operation.
- Optional night quiet modes to reduce outdoor unit sound (4 levels) with automatic activation or manual activation (with MIM-B14).
- Optional snow blowing logic to prevent snow accumulation on idle outdoor units.
- Maximum current control of outdoor unit(s) to limit current (50% - 100% of design current) adjustable at outdoor unit or central control devices: DMS 2 (MIM-D00AN), DMS 2.5 (MIM-D01AUN), BACnet Gateway (MIM-B17N, MIM-B17BUN), LON Gateway (MIM-B18N, MIM-B18BUN).
- Energy savings options to reduce system energy consumption in heating mode when average indoor room temperatures are greater than average indoor set temperatures.
