Troubleshooting - Hayward HeatPro VS HP50952T Manuel D'installation Et D'utilisation

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 continuous-
ly. 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.
NOTICE - A heater damaged by freezing is not covered under the manufactures warranty.
DRAINING THE HEAT EXCHANGER: This procedure applies to installations where the heater is located higher than the pool water level. If itis necessary to drain
a pool heater located below the pool water level, you must either partially drain the pool, or isolate the pool heater from the pool using valves, then perform
draining the heat exchanger.
1. Set the heater to OFF mode.
2. Turn the electricity to the heater OFF at the circuit breaker panel.
3. Be sure the circulating pump is OFF.
4. If no drain plug is provided, open lower inlet water union and allow all water to drain from the heater.
5. Re-install the drain plug or reattach the water union.
SPRING START-UP: This procedure should be performed annually to ready your heater for the upcoming season. In addition to the steps outlined below, it is
recommended that a PERIODIC INSPECTION also be performed.
1. Inspect and clean the heater, being sure the heater is free of leaves and debris prior to startup.
2. Properly attached inlet and outlet piping and confirm the drain valve is closed.
3. Turn the filtration system pump ON and allow the system to run long enough to purge all the air from the lines.
4. Turn the electricity to the heater ON at the circuit breaker panel.
5. Set the heater to H mode and adjust the set point to the desired temperature setting.
6. If operating difficulties are encountered, contact a qualified service company for assistance.
Component Service
NOTICE - Only qualified service technicians, with appropriate test equipment, should be allowed to service the heater. For conditions where refrigerant
must be managed, an EPA certified technician is required. All of the components that comprise the system have an effect on heater operation. Before
proceeding with heater related troubleshooting tips, be certain that the pump is operating correctly, the filters and strainers are not blocked, the valves in
the piping are properly positioned, and the time clocks are properly set.
WARNING
-
components in any manner. To do so may result in a malfunction that could result in death, personal injury, or property damage. Check with
the pool owner to see if any part of the heater has been under water. Replace any electrically operated component that has been under water.
WARNING
-
to servicing. Always disconnect power circuit before connecting the heat pump, or working on the heat pump. This equipment contains wiring
that carries high voltage. Contact with these wires could result in death or personal injury and/or may also cause property damage.
TROUBLESHOOTING: See TABLE 5: Troubleshooting Lookup Chart.
ERROR and OPERATION CODES: See TABLE 6: Display Code Index.
AUTOMATIC RESET TIME: The heater will automatically reset when an error condition is corrected and resume operation.
NOTICE - These instructions are intended for the use of qualified personnel trained and experienced in the installation and servicing of this type of
heating equipment and its related system components. Some states may require installation and service personnel to be licensed. Persons not qualified
should not attempt to repair this equipment according to these instructions. These instructions and procedures are not for the use of "do-it-yourself"
consumers.
NOTICE - As a preliminary check, make sure that all wire connections are clean and tight and that all wiring conforms to the wiring diagram.
