Electrical Installation Temperature Sensor Air outlet temperature sensor is included. Without proper installation of this probe the Make-Up Air unit will not operate correctly. The sensor probe/cable is attached to the control board. However, the sensor probe must be installed external to this unit.
High Voltage Hookup Service Panel Circuit Breaker(s) Sizing – based upon unit size, the specification page shows appropriate service size requirements based on UL and NEC code. Note: These two models require 120VAC source (not 240). Source Power – route and install proper current carrying conductors as per local code requirements, from service panel.
Basic Setup Fan Speed Adjustment – located in the hinged cover low voltage compartment and on the divider is a plastic shaft knob which allows for fine tuning the fan speed. If you do not need full CFM for your application and desire a larger temperature rise, the lower factory default set speed may be adequate.
