38 3. It is normal for the heater to display up to a 5-second delay when the keypad is used to reset the control to clear an error code. 4. The control will accept a mode change during lockout after 5 seconds. The control will continue to display the error code and remain in lockout until it is reset. At reset the control will go to the last saved mode. Automatic reset time: The heater will automatically reset when an error condition is corrected and resume operation as detailed in the table below. The heater can be manually reset using the keypad by cycling the mode button through "STANDBY" and back to the original operating mode ("SPA" or "POOL"). Periodic inspection: The heater is designed and built for long performance life when installed and operated according to the manufacturer's directions. Regular inspection by qualified service personnel is recommended to keep the heater working properly. The following inspection points are suggested to help maximize heater life. 1. Periodically check the venting on outdoor heaters. The heater's venting areas (the louvered top panel) must never be obstructed in any way and minimum clearances must be observed to prevent restriction of combustion and ventilation air. Remember that shrubs grow and in time may obstruct a heater's venting areas. 2. Check the venting of indoor heaters for looseness and possible leaks. Keep all openings for combustion and ventilation air clear and unobstructed. 3. Keep the entire pool heater area clean and free of all debris, combustible materials, gasoline, and other flammable vapors and liquids. Remove any leaves or paper from around the heater. 4. Do not store chlorine, other pool chemicals, or other corrosives in the vicinity of the heater. 5. If the heater is operating on propane gas, the tank must not fall below 30% full or damage to the heater may occur. Hayward will not be responsible for heaters that soot up due to improper gas level in the tank resulting in inadequate gas volume. 6. If another appliance is added to the gas line at a later date, consult the local gas company to be sure the gas line will have the capacity to supply both units at full input rating at the same time. 7. Do not use the heater if any part has been under water. Contact a qualified service technician to inspect the entire heater and replace any part of the control system or gas valve that was under water. If heater has been totally submerged in water it must be removed and the entire heater must be replaced. 8. An inspection program is a good preventative maintenance measure. Keep this manual in a safe place for future reference for yourself as well as for a service technician to consult when inspecting or servicing the heater. Additional inspection procedures to be performed by a qualified service technician are covered in Section VI of this manual. Winterization: In moderate climates, the heater can continue to operate during short-term cold spells. Do not use the heater to maintain the water temperature just above freezing or for freeze protection. Care must be taken to avoid freeze-up in the heater. When it is used during freezing weather, the pump must run continuously. The heater is not warranted against freeze-ups. In regions where freezing temperatures are encountered, all water must be drained from the heater when it is out of service, to prevent damage to the heater and piping. Draining the heat exchanger is recommended as part of the season's shutdown procedures. ATTENTION: A heater damaged by freezing is not covered under the Hayward warranty.
