To install the WhisperKOOL Phantom 24V Thermostat Conversion Kit, please follow the steps outlined in the installation manual provided by WhisperKOOL. Here is a complete step-by-step guide:
1. Before you start, make sure to shut off power to the evaporator and condensing unit. Disconnect the cooling unit from the power source.
2. Using a 5/16" nut driver, loosen the screws securing the evaporator access panel to the unit. Remove the access panel.
3. Locate the controller enclosure and remove the two 11/32" hex nuts securing it to the divider. Pull the enclosure forward and remove the lid using a Phillips screwdriver.
4. Disconnect the wires Pb1, Pb2, Display, and flag connector from terminal #6. Remove the wires from the enclosure.
5. Cut the flag connector from the black wire.
6. Disconnect the 4-pin Molex connector. The original controller enclosure can now be removed completely from the unit.
7. Locate the 24V Conversion Kit and remove the top by removing the 4 screws.
8. Route the black wire from the previous enclosure into the new enclosure. Insert the black wire into the lever connector.
9. Re-install the box cover.
10. Connect the 4-pin Molex connector from the new 24V kit to the existing unit wire harness.
11. Install the new 24V Kit enclosure in the same location as the previous enclosure using the previously removed hex nut hardware.
12. Route 18/5" thermostat wire from the thermostat location to the evaporator unit.
13. Strip off 6" from the thermostat wire casing. Cut and remove the white thermostat wire. Strip off about 1/4" of the blue, red, green, and yellow thermostat wire casing to expose the copper.
14. Drill a 5/16" hole in the previously removed access panel. Insert the provided grommet into the hole and insert the thermostat wire through the hole.
15. Connect the thermostat wires with the provided wire nuts by color matching (red to red, blue to blue, green to green, and yellow to yellow). Secure the wires to the enclosure using cable ties and an adhesive pad.
16. Install the evaporator access panel onto the unit using the previously removed screws. Use cork tape or duct tape to seal around the hole through which the wire was run.
17. Reconnect power to the evaporator unit.
The 24V Thermostat Conversion Kit should now be successfully installed. If you have any further questions or need assistance, please contact WhisperKOOL Customer Service at 1-800-343-9463 or visit their website at www.whisperkool.com.
