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 start-up
1. Ensure that connecting water lines are purged and free of debris
Caution: solder or other debris may cause the furnace pump or check valve to malfunction
2. Blower wheel rotates freely inside its housing
3. Wiring connections are tight
4. All duct and pipe connections are sealed
5. Check that all packaging is removed
6. Front access door is on tight.
7. Fan speed selection:
Heating/Cooling - factory setting is at high speed and can be changed in the
electrical box to medium-high or medium if required.
Once all of the necessary connections have been made, the Air Handler
Start-Up Procedure is as follows:
1. Close shut-off valves separating the Air Handler from the water heater/boiler.
2. Set up water heater/boiler according to manufacturer's instructions.
3. Purge air from unit. To do so, open the supply shut-off valve to the furnace. Attach a garden
hose to drain valve, and drain water until you get a continuous flow. Close the drain valve and
purge the pump. To purge the air from the pump, turn the large screw on the face of the pump
counterclockwise until water leaks out, then tighten. Open the supply shut-off valve.
4. Turn on power supply to Air Handler. Caution: blower will start to operate.
5. Switch the room thermostat to heat. The thermostat should be set higher than the current room
temperature in order to energize the pump and commence the heating cycle. (If the pump does
not start, or the Air Handler is not producing heat, refer to the Troubleshooting Section in this
manual.
6. Set room thermostat at desired temperature setting.
