    AIR/WATER HEAT PUMPS MODELS COVERED IN THIS MANUAL HC HEAT PUMPS These heat pumps are heater chillers, designed for areas of the world where the ambient temperature can vary from 7ºC to 50°C. The pool water is heated when the ambient temperature is low and cooled when the ambient temperature is high, enabling the user to enjoy the pool throughout the year.
