The heat pump is a single, compact, easily installed unit. A 220-volt dedicated circuit and attachment to your existing pool pump is basically all that is required. The machine must meet a minimum clearance requirement, to insure proper airflow. Proper placement is critical to the performance of the pool/spa heat pump. A concrete slab may be required unless there is enough room on an existing slab. If a chlorinating device is present it must be placed downstream from the heat pump and a check valve must be installed to prevent chemical damage.
Compared to other types of heating equipment, (with the exception of solar heaters, which only heats when the sun is present) the AQUAHEAT pump is very economical. Two types of energy sources are utilized to produce the required heat output. This is the heat from the ambient air and electrical power used to run the compressor.
There is no attention required by a Heat Pump as with air conditioner. Simply remove any leaves, grass, paper, etc. which occasionally collects from the air. The pool chemistry should always remain balanced. The evaporator grills are coated to prevent corrosion. However if you live near a salt-water environment you may want to hose down the outside evaporator coil to help prevent the build up of salt and rust.
As with all swimming pool heating systems you are advised to use a pool cover when the swimming pool is not in use. This will keep evaporation (the greatest heat loss) to a minimum and so reduce the overall pool heating costs and unwanted frustrations. A pool cover can cut total heat loss by 50% to 95%.
The AQUAHEAT heat pump has a sealed refrigeration system that is filled with a refrigerant called "freon". The factory charge of freon should last for the life of the unit. Freon is a very stable gas and should not degrade or breakdown even under severe operating circumstances. If your unit needs freon it probably has a leakage which must be located and repaired before more freon is added, otherwise the problem will not be resolved. Fortunately freon leaks are rare and usually only occur due to shipping damage.
