Notes:
1. Heating Data in BOLD = Freeze protection of the source loop is required.
2. Alldataisbasedon100%waterastheheattransferuid.
3. Apply capacity correction factors based on the percent anti-freeze mixture.
4. Do not select units above 120°F leaving water temperature for the load in the heating mode or below 40°F for the load in the cooling mode.
5. Capacity - Btuh produced by the load loop.
6. Load - water loop serving the air handler or terminal device.
7. Source - heat rejection water loop; geothermal or boiler/tower loop.
EWT = Entering water temperature, °F
GPM=Gallonsperminuteow
WPD = Water pressure drop, ft. of water
Btu/h = Btu per hour of heat transfer
LWT = Leaving water temperature, °F

Notes:
1. Heating Data in BOLD = Freeze protection of the source loop is required.
2. Alldataisbasedon100%waterastheheattransferuid.
3. Apply capacity correction factors based on the percent anti-freeze mixture.
4. Do not select units above 120°F leaving water temperature for the load in the heating mode or below 40°F for the load in the cooling mode.
5. Capacity - Btuh produced by the load loop.
6. Load - water loop serving the air handler or terminal device.
7. Source - heat rejection water loop; geothermal or boiler/tower loop.
EWT = Entering water temperature, °F
GPM=Gallonsperminuteow
WPD = Water pressure drop, ft. of water
Btu/h = Btu per hour of heat transfer
LWT = Leaving water temperature, °F

Notes:
1. Heating Data in BOLD = Freeze protection of the source loop is required.
2. Alldataisbasedon100%waterastheheattransferuid.
3. Apply capacity correction factors based on the percent anti-freeze mixture.
4. Do not select units above 120°F leaving water temperature for the load in the heating mode or below 40°F for the load in the cooling mode.
5. Capacity - Btuh produced by the load loop.
6. Load - water loop serving the air handler or terminal device.
7. Source - heat rejection water loop; geothermal or boiler/tower loop.
EWT = Entering water temperature, °F
GPM=Gallonsperminuteow
WPD = Water pressure drop, ft. of water
Btu/h = Btu per hour of heat transfer
LWT = Leaving water temperature, °F

Notes:
1. Heating Data in BOLD = Freeze protection of the source loop is required.
2. Alldataisbasedon100%waterastheheattransferuid.
3. Apply capacity correction factors based on the percent anti-freeze mixture.
4. Do not select units above 120°F leaving water temperature for the load in the heating mode or below 40°F for the load in the cooling mode.
5. Capacity - Btuh produced by the load loop.
6. Load - water loop serving the air handler or terminal device.
7. Source - heat rejection water loop; geothermal or boiler/tower loop.
EWT = Entering water temperature, °F
GPM=Gallonsperminuteow
WPD = Water pressure drop, ft. of water
Btu/h = Btu per hour of heat transfer
LWT = Leaving water temperature, °F

Notes:
1. Heating Data in BOLD = Freeze protection of the source loop is required.
2. Alldataisbasedon100%waterastheheattransferuid.
3. Apply capacity correction factors based on the percent anti-freeze mixture.
4. Do not select units above 120°F leaving water temperature for the load in the heating mode or below 40°F for the load in the cooling mode.
5. Capacity - Btuh produced by the load loop.
6. Load - water loop serving the air handler or terminal device.
7. Source - heat rejection water loop; geothermal or boiler/tower loop.
EWT = Entering water temperature, °F
GPM=Gallonsperminuteow
WPD = Water pressure drop, ft. of water
Btu/h = Btu per hour of heat transfer
LWT = Leaving water temperature, °F

Notes:
1. Heating Data in BOLD = Freeze protection of the source loop is required.
2. Alldataisbasedon100%waterastheheattransferuid.
3. Apply capacity correction factors based on the percent anti-freeze mixture.
4. Do not select units above 120°F leaving water temperature for the load in the heating mode or below 40°F for the load in the cooling mode.
5. Capacity - Btuh produced by the load loop.
6. Load - water loop serving the air handler or terminal device.
7. Source - heat rejection water loop; geothermal or boiler/tower loop.
EWT = Entering water temperature, °F
GPM=Gallonsperminuteow
WPD = Water pressure drop, ft. of water
Btu/h = Btu per hour of heat transfer
LWT = Leaving water temperature, °F

Notes:
1. Heating Data in BOLD = Freeze protection of the source loop is required.
2. Alldataisbasedon100%waterastheheattransferuid.
3. Apply capacity correction factors based on the percent anti-freeze mixture.
4. Do not select units above 120°F leaving water temperature for the load in the heating mode or below 40°F for the load in the cooling mode.
5. Capacity - Btuh produced by the load loop.
6. Load - water loop serving the air handler or terminal device.
7. Source - heat rejection water loop; geothermal or boiler/tower loop.
EWT = Entering water temperature, °F
GPM=Gallonsperminuteow
WPD = Water pressure drop, ft. of water
Btu/h = Btu per hour of heat transfer
LWT = Leaving water temperature, °F

Notes:
1. Heating Data in BOLD = Freeze protection of the source loop is required.
2. Alldataisbasedon100%waterastheheattransferuid.
3. Apply capacity correction factors based on the percent anti-freeze mixture.
4. Do not select units above 120°F leaving water temperature for the load in the heating mode or below 40°F for the load in the cooling mode.
5. Capacity - Btuh produced by the load loop.
6. Load - water loop serving the air handler or terminal device.
7. Source - heat rejection water loop; geothermal or boiler/tower loop.
EWT = Entering water temperature, °F
GPM=Gallonsperminuteow
WPD = Water pressure drop, ft. of water
Btu/h = Btu per hour of heat transfer
LWT = Leaving water temperature, °F

Notes:
1. Heating Data in BOLD = Freeze protection of the source loop is required.
2. Alldataisbasedon100%waterastheheattransferuid.
3. Apply capacity correction factors based on the percent anti-freeze mixture.
4. Do not select units above 120°F leaving water temperature for the load in the heating mode or below 40°F for the load in the cooling mode.
5. Capacity - Btuh produced by the load loop.
6. Load - water loop serving the air handler or terminal device.
7. Source - heat rejection water loop; geothermal or boiler/tower loop.
EWT = Entering water temperature, °F
GPM=Gallonsperminuteow
WPD = Water pressure drop, ft. of water
Btu/h = Btu per hour of heat transfer
LWT = Leaving water temperature, °F

Notes:
1. Heating Data in BOLD = Freeze protection of the source loop is required.
2. Alldataisbasedon100%waterastheheattransferuid.
3. Apply capacity correction factors based on the percent anti-freeze mixture.
4. Do not select units above 120°F leaving water temperature for the load in the heating mode or below 40°F for the load in the cooling mode.
5. Capacity - Btuh produced by the load loop.
6. Load - water loop serving the air handler or terminal device.
7. Source - heat rejection water loop; geothermal or boiler/tower loop.
EWT = Entering water temperature, °F
GPM=Gallonsperminuteow
WPD = Water pressure drop, ft. of water
Btu/h = Btu per hour of heat transfer
LWT = Leaving water temperature, °F

Notes:
1. Heating Data in BOLD = Freeze protection of the source loop is required.
2. Alldataisbasedon100%waterastheheattransferuid.
3. Apply capacity correction factors based on the percent anti-freeze mixture.
4. Do not select units above 120°F leaving water temperature for the load in the heating mode or below 40°F for the load in the cooling mode.
5. Capacity - Btuh produced by the load loop.
6. Load - water loop serving the air handler or terminal device.
7. Source - heat rejection water loop; geothermal or boiler/tower loop.
EWT = Entering water temperature, °F
GPM=Gallonsperminuteow
WPD = Water pressure drop, ft. of water
Btu/h = Btu per hour of heat transfer
LWT = Leaving water temperature, °F
