Considerations when replacing a blower

  When replacing a hot tub blower, there are a few important factors to consider. One of the most important considerations is ensuring that the voltage of the replacement blower matches the voltage of your hot tub’s electrical system. This is because using a blower with the wrong voltage can result in damage to the blower, the hot tub’s electrical system, or both. Check if the blower you are replacing is 230V or 120V – it makes a difference!   While the power of the blower is not necessarily important, it’s a good idea to select a replacement blower that has a similar power rating to your existing blower. This will help ensure that the replacement blower is capable of producing the desired air pressure and flow rate in your hot tub.   Another factor to consider when replacing a blower is the size of the blower’s outlet pipes. If the replacement blower has different pipe sizes than your existing blower, you may need to use adaptors or convertors to connect the blower to your hot tub’s plumbing. This is important to ensure that the blower is properly connected and doesn’t leak air.   In summary, when replacing a hot tub blower, it’s important to match the voltage of the replacement blower to your hot tub’s electrical system and consider the power rating and pipe sizes of the replacement blower. By selecting a replacement blower that matches these criteria and ensuring that it’s properly installed, you can help ensure that your hot tub continues to provide a relaxing and enjoyable experience.  

Don’t forget the Check Valve!

  A check valve is an important component to consider when installing a hot tub blower. A check valve is a one-way valve that allows water to flow in one direction only, preventing backflow. In a hot tub, the check valve is typically installed on the air line between the blower and the jets. This keeps the water out of your blower – last thing you want is water in your blower. There are a few reasons why a check valve is important when using a hot tub blower:

1. Prevents water from entering the blower: Without a check valve, water can backflow from the hot tub plumbing into the blower when the blower is turned off. This can cause damage to the blower and can also create a safety hazard if water comes into contact with the blower’s electrical components.
2. Maintains air pressure: A check valve helps maintain the proper air pressure in the hot tub system. Without a check valve, air can escape from the hot tub jets when the blower is turned off, reducing the water pressure and the effectiveness of the massage feature.
3. Reduces noise: A check valve can help reduce noise in the hot tub plumbing system. When the blower is turned off, water can flow backwards through the air line and create a gurgling or burping noise. A check valve prevents this noise from occurring.

In summary, a check valve is an important component to consider when installing a hot tub blower. It helps prevent water from entering the blower, maintains air pressure, and reduces noise in the plumbing system. By including a check valve in your hot tub blower installation, you can help ensure that your hot tub runs smoothly and efficiently.  

Wiring a Hot Tub Blower

          When wiring a hot tub blower, it’s important to not only follow the manufacturer’s instructions but also to check the pin out diagram on the spa pack. The pin out diagram will show you the location of the various terminals and connectors on the spa pack, which you’ll need to connect to the blower. Here are the steps to wire a hot tub blower while checking the pin out diagram on the spa pack:

1. Turn off the power to the hot tub at the circuit breaker.
2. Locate the spa pack, which is usually located near the hot tub. Look for the pin out diagram, which should be located on the inside of the access panel.
3. Determine the voltage requirements of the blower. Most hot tub blowers operate on 120 volts, but some may require 240 volts. Make sure you have the correct voltage before proceeding.
4. Connect the blower to the control system. The blower should have a set of wires that connect to the spa pack. Match the wires from the blower to the corresponding terminals on the pin out diagram. Make sure to follow the manufacturer’s instructions for the proper wiring sequence.
5. Connect the blower to the power source. The power source is usually a dedicated GFCI breaker or a GFCI outlet that is installed near the hot tub. Again, follow the manufacturer’s instructions and match the wires from the power source to the corresponding terminals on the pin out diagram.
6. Test the blower to make sure it’s working properly. Turn on the power to the hot tub and activate the blower from the control panel. The blower should start up and produce the desired amount of air.
7. Secure all wiring connections and close the access panel to the spa pack.
8. Turn on the power to the hot tub at the circuit breaker.
