Electric Heat Section

(Optional)
Optional factory installed electric heat section consists of
open coil duct heater mounted to the unit at the supply fan
discharge. Heat section includes heating coils and an electrical
control box with single point field power connection for heater
and supply air fan.
Factory provided field knockouts are located on the side
of the electric heat control panel for field power and
control wiring to pass through. A factory installed non-
fused disconnect is located in the electric heat control
panel to disconnect power to the supply air fan and heater
components. All wiring must be in conformance with the
national electric code and local restrictions.

Quality Control
• Heaters are di-electrically tested for 1000V plus twice the
rated volts, or 2000V whichever is greater. The resistance
of each heater is measured and recorded and must be
within 5% of the rated value
• Every heater is checked during the production process
and as a final assembly
