Voltage

If your existing spa pack runs on 220 volt current, you should order a replacement spa pack that runs on 220V too. A 220 volt system is really two dedicated 110 volt wired paralleled to each other. In 110 volt systems the electric current is pulsed in one direction. In 220 volt systems the current is alternately pulsed in both directions. So, a 220 volt system can run 110 volt accessories, but a 110 volt system cannot run anything that requires 220 volts.

If your spa currently runs on 110 volt current, you should consider upgrading to 220 volts. This will, however, require you to change the wiring and circuit breakers between your home’s electrical control box and your spa.

With the upgrade you’ll get the following benefits:

• Your spa heater will be able to run while your spa pump is running on high speed. With 110V when the pump is on high speed there’s not enough power left over to run the heater.
  


• The heater will run at 5.5 kw on 220 volts versus just 1.5 kw on 110 volts, so your spa will heat up more than three times faster.
  


• If your spa has more than 7 jets, a 110V spa pump may be underpowered for the size of your spa. 110V spa pumps cannot be bigger than 1.5 horsepower. Generally a spa pump needs 1 horsepower for every 4 jets.
  

The spa pack’s price is the same for 220V or 110V. If you have a 110V system you’ll probably be very happy with the improved performance of your spa if you upgrade.

When ordering a 220 volts Controller, we highly recommend a Spa Side GFCI Load Center to protect the bather if it hasn't already been installed.
