50 Section V. Troubleshooting General: ATTENTION: 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 or the use of "do-it-yourself" consumers. WARNING: BURN HAZARD The operation of the heater with the pump shut off could cause heater overheating and fire. Never operate heater with the pump shut off. ATTENTION: As a preliminary check, make sure that all wire connections are clean and tight and that all wiring conforms to the wiring diagram. 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 ("POOL" or "SPA"). Error codes: See Figure 52 for an error code chart. Troubleshooting: See Figure 53 for troubleshooting guide. Supply wiring: If the heater is connected to the line side of the circuit it will be powered at all times. In this situation, when the pump shuts down the heater will display a fault code of "LO". If there is a call for heat and the pump then restarts there will be a 2-minute delay for the heater to fire. After the pump has been running for at least 2 minutes there is no delay for heater operation. Wiring the heater to the load side of the timer or controller will not result in a 2-minute delay if the pump primes quickly enough to activate the heater's water pressure switch. If the pump is slow to prime the heater may display an "LO" fault code and will take 2 minutes to automatically restart. If the pump has primed, this wait can be avoided by manually clearing the error code via the keypad by changing the mode through the "STANDBY" setting and returning to the initial setting ("SPA" or "POOL"). When a heater is wired to the line side of the power circuit (continuous power) the blower will not operate when the pump is cycled via a time clock or other switch method.
