Start Up Procedure
In order for any appliance to work properly it must be set up and tested by a knowledgeable technician.
The following conditions must be met prior to
1.Blower wheel rotates freely inside its housing.
2.Wiring connections are tight.
3.Water is sitting in the "P" trap below the HRV core.
4.All duct and pipe connections are sealed.
5.Front access door is on tight.
Once all of the necessary connections have been made, the Clean Air Furnace
1.Turn on power supply to Clean Air Furnace. Caution: The blower will start running at a lower speed.
2.Switch the room thermostat to heat. The thermostat should be set higher than the current room temperature in order to energize the unit and commence the heating cycle.Verify heat cycle starts.
3.Set room thermostat at desired temperature setting.
4.Switch fan to manual at the thermostat so the unit will run at high speed in order to perform the balancing pro- cedure on the ventilation section.
Note: For ECM motors, refer to note located on this page regarding high speed fan operation.
5.After balancing the ventilation according to instructions, set the thermostats fan switch to "auto". On "auto" the fan will run continuously at a low speed if the ventila- tion switch (fig. 6) is in the continuous mode, until heating or cooling is called for and then will switch to a higher speed. On "manual" the fan will run at high speed continuously.
NOTE: Continuous low speed can be turned ON/OFF with the ventilation switch, (fig. 6).
NOTE: Continuous high speed can be obtained by switching thermostat fan switch to manual/on.
NOTE: For models with the ECM blower motor. Low speed fan is controlled by the thermostat fan switch (R and G terminals).
High speed blower operation is obtained by making a dry contact closure across R and the Orange wire from the ECM motor.
NOTE: Downflow models incorporate a flow switch to verify blower operation and air- flow. If airflow is not sensed or the pressure switch is blocked, the electric heating elements will NOT start. NEVER override or disable safety switches. If air- flow is blocked or too low, the airflow MUST be diagnosed and corrected.
