Allow all the condensation to drain from the unit for at least an hour or so. Then start the circulation pump only, leave the heater off. If the unit is still leaking water steadily, you may have a water piping leak. The unit should not condensate when the heater is off. Consult your dealer. 15 FILTER SYSTEM MAINTENANCE REQUIREMENTS WATER FLOW Proper water flow is critical to the heaters performance and longevity. The maintenance of your filtering system is directly related to the proper operation of the heat pump. See pages 8 for other information regarding filter cleaning and the start up procedures. CIRCULATION PUMP The circulation pump must be kept in good working order to provide a steady rate of flow to the heater and filtering system as a whole. The circulation pump must be producing a flow rate in accordance with the manufacturers specifications within 10%. The pump should run with a "full prime" without excessive restriction on the vacuum and pressure side of the filtering system. Discharge Outlet Pump Lid ElectricMotor Lint Trap "Pressure" "Suction" Inlet Impeller Housing Typical Circulation Pump VACUUM & PRESSURE LEAKS All vacuum and pressure leaks in the filtering system must be eliminated immediately after occurring. Air allowed into the filter system from the vacuum side of the circulation pump will cause premature wear and physical erosion to the heat exchanger and water piping inside the heater. Air turbulence will cause the water pressure switch to malfunction. Pressure leaks on the filtering system will allow the system to lose vacuum and cause the water in the filter and piping to back siphon or reverse flow through the system when the circulation pump is off. Reverse flow may cause the water pressure switch to malfunction. CHLORINATORS See chlorinator placement and chemical use guidelines. 16 FILTER CLEANING & CARE Your filter system should be cleaned at least twice a month. See manufacturer's directions for proper filter cleaning methods. Size and conditions may require you to clean the filter more often. A filter is considered "dirty", whenever it restricts the flow rate by 10% or more. You can use the pressure gauge on the filter tank to determine a restriction in the filter due to clogging. After the filter has been replaced or when it is new, you should record the actual operating pressure with a "clean filter". When the pressure increases more than 5 p.s.i., the filter should be cleaned. If the pressure does not return to normal you must replace it. Make sure your pressure gauge is kept in good working condition. Filter Tank Air Bleed Valve O-Ring Inlet Outlet Locking Nut & PSI O-RingGauge Typical Cartridge Filter Element There are some after market filter element cleaning solutions that will help remove oil and minerals that may clog the filter. Oil and minerals can not be removed with normal cleaning and back-washing. Spas are particularly susceptible to oil build up in the filter. Do not acid wash a filter until you have removed all oil and grease with a solution designed to remove such. Acid washing a filter with oil in it will cause that oil to become permanently embedded in the fibers. Cartridge filter element replacement is suggested every 1 to 2 years. Sand filters should have the sand replaced every 3 to 5 years. D.E. type filter elements should be removed and soaked in a solution at least every two years. stuck to the main drain port. stuck to the main drain port. Automatic pool cleaners will decrease the water flow by restricting the suction of the circulation pump. Most automatic type pool cleaners operate from the suction provided by the circulation pump. Some automatic pool vacuums are plugged into the skimmer suction port. The main floor drain is then restricted some, so that the auto vac has enough vacuum to operate. It can then move freely and not become ! CAUTION When manually vacuuming the pool or performing service to the filtering system, "shut the heater off !" When the vacuum hose is plugged in, it may cause the pump to loose prime due to the air in the hose. You may also need to restrict the main drain suction port to gain more vacuum to the vacuum hose and head. This will lower the overall flow through the unit and cause it to cycle on & off, possibly causing damage. Shut the heater off whenever there is a chance of restricted water flow or loss of prime. Typical PROFESSIONAL SERVICE Automatic As part of routine maintenance you should schedule a Pool Cleaner licensed air conditioning contractor or the factory service department to check the refrigeration circuit and components of the heat pump against factory specifications. An improper adjustment or diagnosis by others may limit your warranty. You can call the factory service department for a list of factory authorized service Often times, when these auto vacuums begin to wear, centers in your area. Have all the refrigeration compo they require more suction from the pump to operate. nents checked against t...
