Page 13 of 22 HEATPRO HEAT PUMP Changing Temperature Display (All Models): HP13023772 Rev: D The control will display temperatures in either degrees Fahrenheit or Celsius. To change the temperature display, place the heat pump in "Stand-By" mode so that the scrolling dots appear on the screen. Press and hold both the pool button and the down arrow button for two seconds and release. Place the heat pump back in pool or spa mode and the temperature change will be displayed. When viewing the temperature in degrees Fahrenheit only the numeric temperature is displayed, but when viewing degrees Celsius the control will display the numeric temperature followed by a lower case "c". Lock Out Feature (All Models): A lock out function is provided to keep the temperature set point from being changed. To engage this function in the pool or spa mode press the up arrow button, down arrow button and pool button at the same time and hold for 2 seconds. The control display will read "LOC" while the lock out function is engaged. To exit the lock out function in pool or spa mode press the up arrow button, down arrow button and pool button at the same time. Defrost Function (All Models): The Defrost function is provided to prevent the evaporator coil from freezing when the outside air temperature is near 50°F (10°C). There is no exact temperature at which this function will operate, as each unit will vary depending upon conditions surrounding the heat pump, clearance around the heat pump and heat pump maintenance. This time period will vary from 15 minutes to several hours. Maintenance Water Chemistry Proper chemical balances are necessary for sanitary swimming conditions as well as ensuring your heat pump's long term reliability. Sanitizing Equipment Sanitizers, if used, MUST be installed downstream of the heat pump (in the return line to the pool) and a check valve installed in a manner that will not allow the raw chlorine to drain back to the heat pump when the water filter pump is off. This will prolong the overall life of the heat pump. DO NOT POUR CHEMICALS DIRECTLY INTO THE SKIMMER. Inspection and Service Hayward HeatPro heat pumps are designed and constructed to provide long performance life when installed and operated properly under normal conditions. Periodic inspections are important to keep your heat pump running safely and efficiently through the years. Keep all objects off the top of the heat pump. Blocking airflow could damage the unit and void the warranty. USE ONLY HAYWARD GENUINE REPLACEMENT PARTS Pomona, CA Clemmons, NC Nashville, TN Tel: 908.351.5400 www.haywardpool.com
