THIS PROCEDURE MUST BE PERFORMED BY A QUALIFIED TECHNICIAN.
WARNING
HAZARDOUS VOLTAGE: Risk of electric shock. Can cause injury or death. Heater may be connected to more than one branch circuit. Disconnect power to all circuits before servicing.
Part Numbers Covered:
Item #1021037R-120 Blower 2002/2003/Quantum 120V REPL
Item #1021037R-240 Blower 2000/Quantum/3100/4100 240V REPL
Included:
- Blower
- 1100 Ohm 50 Watt Resistor
- 250 Ohm 50 Watt Resistor
NOTE: When replacing a blower in a 2000 Series heater, it is important to make sure the blower resistor is correct for the application. Read and follow instructions carefully to ensure proper installation and operation.
Disconnect Power
Disconnect power to all branch circuits of the heater.
Remove Painted Front Panel
Remove painted front panel by removing the screws located on the bottom edge of the painted front panel.
Remove Mounting Plate
Remove the control circuit board mounting plate (Figure 1) by sliding it off its mounting screws. Hook it on these same screws using the eyelet’s provided on the front of the mounting plate for ease of service and access to the electrical compartment.
Remove Spring
Release the spring (Figure 2) that is holding the blower in place.
Remove Wires
Disconnect ground wire and line voltage wiring to the blower at the quick disconnects.
Replace Blower
Remove the old blower and install new blower.
NOTE: Use care to not damage element ends and other connections. Removing the blower can be difficult due to the wiring. To make this process easier, clip tie wraps as necessary.
Disconnect Blower Wires
Connect ground wire and line voltage wires, making sure to tap the motor for the appropriate voltage for the application. Reference the wiring schematic on the blower motor.
Reconnect Spring
Reconnect the spring (Figure 2) to hold the blower in place and avoid vibration noises.
Check Resistor
Check the ohm value of the blower resistor in the heater. Blowers manufactured by different companies require different resistors. See resistor table for information required for the application:
Replace Resistor
If necessary, replace the blower resistor (Figure 3).
Re-install Control Panel
Place control panel back to operating position. See Figure 1.
Energize Heater
Restore power to the heater.
Adjust Locations
There are no locations to adjust in 2000-Series heaters, Quantum units only
Check Blower
Verify blower operation.
Install Painted Cover
Re-install the painted front panel.
