How to Install a Hot Tub Thermostat How to Install a Hot Tub Thermostat
When you install or replace a hot tub thermostat, you must remember to stay safe and follow all instructions precisely. The steps below explain how to install a hot tub thermostat in a safe manner.
Step 1 - Prepare for Safety
Before you start working on your hot tub thermostat, you need to take precautionary measures to stay safe so you don't pose any danger to yourself or others.
Unplug your hot tub at the breaker box so all power going to the hot tub is disconnected. You will also want a pair of shoes with rubber soles. Rubber protects you by being grounded when you work with wires.
Step 2 - Remove the Covers
Locate and remove the motor cover. Make sure you keep the screws that hold the casing in place.
You will also be removing other screws, so you need to keep these screws separate from any other ones. Use your baggie to store these for now.
Step 3 - Remove the Housing Cover
Now that the motor cover is removed, you can move onto the housing cover. Remove that as well, by using your screwdriver to loosen the screws, and then place those screws into a separate bag.
Step 4 - Insert the New Hot Tub Thermostat
Take your newly purchased thermostat out of the box and slide it into the holder. Then you must tighten the nut that holds it.
Step 5 - Attach the Wires
If you are replacing an existing thermostat that needed some repair, you want to attach the wires as they were when you took the old thermostat out of place.
If you are inserting a new hot tub thermostat, follow the manual that came with your new thermostat. This manual will explain the best, as well as the safest, route to take when you are wiring your hot tub thermostat.
Step 6 - Replace the Covers
Replacing the housing cover first. Use the correct screws you saved in your baggie to tighten the cover back on and into place. After you've replaced the housing cover, you need to replace the motor cover as well. Use the correct screws to do this, and make sure the cover is secure.
Step 7 - Test It Out
Now it's time to turn the breaker back on and plug in your spa. Check to see if your hot tub heats up, and you're good to go.
