v IMPORTANT SAFETY PRECAUTIONS (continued) Swimming Pool Energy Saving Tips It is important to note that a heat pump will not heat a pool as fast as a large gas or electric pool heater. If the pool water is allowed to cool significantly, it may take several days to return to the desired swimming temperature. For weekend use, it is more economical to maintain the pool water temperature at or near your desired swimming temperature. If you do not plan to use your pool for a prolonged period, then y

5 Clearances All criteria given in the following sections reflect minimum clearances. However, each installation must also be evaluated, taking into account the prevailing local conditions such as proximity and height of walls, and proximity to public access areas. The heat pump must be placed to provide clearances on all sides for maintenance and inspection. 1. At least 24 in. [61cm] access must be available in the front and 12 in. [30 cm] on all the other sides of the heat pump for service, se

6 Drainage and Condensation Condensation will occur from the evaporator coil while the unit is running and drain at a steady rate, usually three to five gallons per hour, depending upon ambient air temperature and humidity. The more humid the ambient conditions, the more condensation will be produced. The bottom of the unit acts as a tray to catch rainwater and condensation. Keep the drain holes, located on the bottom pan of the base of the unit, clear of debris. Lawn Sprinklers N NO SPRINKLERS

9 Multiple Unit Installation Heat Pump, Heater and/or Solar Combination In certain regions of the country it may be more economical to run a heat pump during the warmer months and a gas heater during the cooler months. In some situations it may be desirable to run the heat pump in the “Chiller” mode, if so equipped, during the hottest portion of the year and a heater during the cooler months. The Pentair Water heat pump may be used in conjunction with a gas or electric heater or any combination

10 Multiple Heat Pump Connections All plumbing on multiple heat pump installations must be done in parallel see Figures 9 and 10. An equal flow of water to each heat pump is important for optimum operation. NOTE: It may be necessary to adjust water pressure switch if a unit is installed below the water level. See page 20 for details on when and how to adjust the pressure switch. Each heat pump allows a maximum flow rate of 125 gpm and requires a minimum of 30 gpm. 24 inches min. clearance around
