Adjusting a Hayward Heat Pump's Water Pressure Switch

A swimming pool can provide a vacation in your backyard. A pool heater extends your swimming season during the cool fall days by warming the water. A heat pump is an electrically powered heater that works similarly to a home air conditioner. It removes the heat from the outdoor air and transfers that energy to the pool water. Hayward pool heaters have water pressure switches that are designed to turn off the heater if the water pressure gets too low. This protects the exchanger from damage from overheating.
