*NOTES:
Digits 3, 16, 17 & 24 are not used in this model.
All heaters come with standard features: Disconnect Switch, Air Flow Switch (non-adjustable), Power Fusing, and Control Transformer.
Descriptions of features and options are found in the installation and operation manual.
Several intergrated electric heater options are limited to specific configurations of the DOAS unit in which the heater is installed. Please refer to the DOAS configuration to determine
whether the below restrictions apply.
Restrictions:
1: Heater density should be less than 30kW/ft².
2: Heater capacity kW entered as a whole number.
3: Formulas for calculating kW and temperature rise:
4: Stage Code "1" is only available when amperage is less than 96A.
5: Stage Code "4" is only available when amperage is greater than or equal to 96A.
6: Control Box Offset Code "D" is only available with Unit Model "DN-3-" and "DN-5-". Heat sinks on the left size of control box.
7: Control Box Offset Code "V" is only available with Unit Model "DN-2-". Heat sinks on the left side of control box.
8: Width Code "24" is only available with Model Code "DN-2-".
9: Width Code "30" is only available with Model Code "DN-3-" and "DN-5-".
DENSITY = HEATER CAPACITY (kW) < 30
