After numerous years of use your Haliburton spa may require some service to keep it running like new. If you’re experiencing temperature issues with your hot tub, a heater replacement may be needed. Follow these steps to remove your old Haliburton heater tube.
Step 1 – Disconnect the power supply and remove the mothership from the spa cabinet. Be sure to dump out any extra water that may be within the mothership. (TIP: Plastic bags can be squished up into a ball and inserted into the intake and outtake pipes of the spa to block the water and save you the process of emptying out the Haliburton)
Step 2 – Remove the motherboard frame. To do this you first unplug the pump and the blower from the motherboard frame. Then unscrew the two unions connecting the heater to the mothership (be sure to keep the rubber gaskets and replace when reassembling). Next take out the four screws securing the frame to the base. Lastly be sure to disconnect the grounding wire from the pump.
Step 3 – With the motherboard frame removed from the base, take off the back plate by removing the four screws holding it in place
Step 4 – Carefully remove the four nuts holding the heater in place using a wrench. CAUTION: The middle two nuts on the heater terminals can be difficult to remove, and we recommend that you use a second wrench positioned underneath the nut to ensure the connection doesn’t break. This can be an awkward step and may require an extra hand to hold the wires out of the way.
Step 5 – Pull off the two black connections from the heater
Step 6 – Remove the two screws located on the outside of the frame that hold the heater in place.
Step 7 – Carefully twist out the heater until it is removed from the frame
Step 8 – Take out the wingnut holding the hi-limit sensor in place underneath the heater tube
Congratulations! If you have reached this point you have successfully disassembled the heater from the mothership. Repeat the same steps in the opposite order to install a new heater.
