SPECIFICATIONS
C. MAIN WIRING PORT (CONT.)
When the main port is wired and power supply turned on, the electronic control panel is activated. A second wiring
port is located next to the main wiring port and is labeled 'Back up heater'. Under normal operation, only the main
wiring port must be wired and the Back-up heater wiring port must remain un-wired. The back-up heater is an
emergency heating source and must be wired only when a system failure is preventing the unit from operating
normally. This procedure must be authorized by AirGenerate and performed by a qualified technician. Failure to do so
will void the warranties on the product.
