Preparing For The Activation

Before you activate your jandy pool heater, you need to make sure that everything is in order. Here are the essential things to prepare:

Check The Weather Conditions To Ensure That It’S Suitable For Pool Heating

Before you activate your pool heater, it’s important to check the weather conditions. You don’t want to waste energy and money heating your pool when you won’t be using it. Here’s what to look for:

Check The Water Level In The Pool And Make Sure It’S At The Appropriate Level

The water level in your pool is essential for proper pool heater operation. If the water level is too low or high, it can cause the heater to malfunction. Here’s what to do:

  • Check the water level in your pool before activating the heater. The water must be at the appropriate level, which is usually halfway up the skimmer.
  • If the water level is too low, add water to bring it up to the right level. If it’s too high, use a submersible pump to remove some of the water.
